Background technology

Cordless communication network often uses some characteristic of representing the network different piece or the information of parameter.For example, some mobile wireless navigation systems estimate that by using wireless measurement portable terminal operates with respect to the position of the known location of wireless network access point.For the particular case of cellular mobile phone navigation system, these access points are honeycombs.

The estimation portable terminal need be understood the correlation properties of those access points with respect to the navigation system of the position of one or more wireless network access points.For example, in the mobile honeycomb navigation system based on thick cellular marker, correlation properties generally include the geographical coordinate at peculiar identifier of honeycomb and honeycomb place.

More accurate system has also introduced the system that wireless signal is measured such as those in computing, need extra configuration information.This generally includes transmitting power, antenna gain and antenna direction.

The performance of such navigation system depends on the integrality of the database of the configuration information that comprises this network to a great extent.This dependence can increase in the system that is hopeful higher levels of spatial resolution or accuracy.In the ideal case, the configuration of cellular network is with the matching network database.But experience in the past shows, is difficult to maintain configuration information usually, strides that a plurality of databases send configuration informations and configuration information often has many mistakes.

The reason of the deviation between provisioning database and the actual disposition may be network data base or network configuration or these two.Database may be because following mistake and not right, such as the literal error, particularly Shuo Zi transposition during the data input; Be used to collect and put in order the problem that the processing of network data has; Send the failure of database to change with network configuration.On the contrary because the mistakes such as failure that the network of literal error when keying in configuration detail and the one or more hope of configuration changes, network configuration may not can with desirable the same.

Another problem of operator is that network configuration is not static.In the whole life-span of network, all might be inconsistent between the configuration of network data base and employing.Network configuration can change when increasing the site with raising capacity and/or covering.When being disengaged trust, honeycomb also can change.Also can change when supporting the capacity of the increase that incident such as important competitive sports and outdoor concert for example is required having supported when setting up mobile cellular (being called cell on wheels (Cells-On-Wheels)).To this interim increase of network with delete sustainable several hours and can last for days in some cases.When existing because when scheduled maintenance, equipment failure or power failure and idle honeycomb, but the configuration Iterim Change.Readjust network when improving performance or adapting to the change that takes place for above-mentioned reasons the technician, network also can change.

The mistake of network data base causes also causing unacceptable service quality for the user in some cases based on the corresponding mistake in corresponding mistake in the operation of system of location and the service that is associated.Drive the test (drive test) except carrying out with wireless surveillance equipment around the network, network operator has no idea to verify the same that network configuration must be with plan.It is that up-to-date cost has been represented concerning the service provider and increased sizable operation burden that database update is become database is continued.

The operator of mobile wireless network changes the configuration of network and the reason of increase network for example is performance improvement and capacity increase etc.When making these changes, all relevant navigation systems all need be upgraded at the configuration that changes.If cannot do the performance that will reduce navigation system like this, might reach the degree that makes navigation system invalid.

The objective of the invention is to make correction and safeguard that mobile network's configuration information is more convenient.

The supervising the network inconsistency

Term " inconsistency " is used for representing any different between the expression of network of real network configuration and network.Inconsistency can include but not limited to: lack the network element that has in the real network in the database, have the network element that does not have in the real network in the database, and/or the value of the network parameter in the database is different with value in the actual database.

When system detected inconsistency, this problem needed to solve.One aspect of the present invention is to use the described method of following chapters and sections to come provisionally or solution for good and all causes the network of configuration and the problem of the inconsistency between the network data base.Described method can be used independently and/or use with any sequential combination ground.Although utilize the detail of some function of this method to change according to the character of described inconsistency, described method can be applicable to the detected inconsistency of all-network.Such function has been described in the other parts of this specification.

Directly notify (Direct Notification)

A kind of mechanism that is used to find the correction that change that network is made or database are required is to implement via the direct notice that network operator 40 is made.Network operator 40 can provide this information to include but not limited to the incident of following incident with response to navigation system 30: the configuration of network 10 is modified, and finds mistake and detect and report to operator's inconsistency in network data base 50.Network operator 40 provides data guaranteeing the accurately current configuration of reaction network 10 of network data base 30, and guarantees that the service performance that depends on network data base 50 can not damaged because of evitable Database error.

The detection method of describing in the common unsettled PCT application of mentioning before can detect the network 10 that is configured and the inconsistency between the network data base 50, but the basic reason server 30 that may be not easy to be positioned identifies under many situations.Location-server 30 is to Systems Operator's 40 notice inconsistencies.Network operator can be determined the basic reason of inconsistency then, determines necessary correction and provides network data base to upgrade to compensate this inconsistency to location-server.In some cases, preferably when determining basic reason, provide interim workaround to inconsistency.Method described herein is supported this interim solution.

Database is corrected or the form of the notice that network configuration changes can be new network data base, thus, can be by relatively this new network data base and current database are determined described change (change of the increase of honeycomb, deletion and parameter).Another selection of network operator provides the database increment, and the institute that this database increment has been listed network changes, and comprises the deletion and the increase of honeycomb.In addition, described network data base upgrade can comprise to which change be correct and which change be owing to network be reconfigured cause indication.

Detect inconsistency and reporting system operator

Fig. 1 shows the system architecture of the network inconsistency that is used for detecting mobile radio communication network 10, it comprises transmitting base station (Base Transmitting Station) 11, and in some embodiments to the suspicious inconsistency of network operator 40 reports.Radio Measurement to the network wireless signal of telecommunication is to be made by for example radio receiver of mobile radio terminal 20.In one embodiment, these measurements are sent to network processing unit such as location-server 30, might send by using the same mobile radio communication network of making measurement at first.Location-server 30 is handled these and is measured, they are compared with the data in being stored in network data base 50, and when detecting inconsistency by utilizing one or more communication mechanisms that this inconsistency is passed to network operator 40.

Fig. 2 shows the general handling process that is used to detect inconsistency and such inconsistency is reported to the Systems Operator.This processing originates in step 100.At step 101 place, for example obtain network measure from one or more mobile radio terminals from network.In step 102, the measurement that analyze to obtain also should be measured and network data base 50 compares, to determine whether to exist any inconsistency.In another form, this network measure can analyzed mistake and is identified one or more inconsistencies.Under these circumstances, the report of carrying out to system can be the relevant details of being reported now with detecting in the past of actual inconsistency.Describe in the common unsettled PCT patent application that this inconsistency is mentioned before can using one or a plurality of methods detect.In one form, this inconsistency can reported when detecting inconsistency.In another form, inconsistency or measurement can be put in order in the report that produces, and this report is with the number of times of appointment or send to the Systems Operator at interval.In another form, when detected inconsistency outnumber the threshold value of configuration the time this inconsistency can be incorporated in the report that is generated and sends to the Systems Operator.

In step 103 and 104, if the inconsistency of detecting, then the reporting system operator 40.This processing finishes in step 105.

Described then operator can determine the basic reason of described inconsistency and utilize administration interface (as will be described in more detail above) that renewal and/or correction to described database 50 are provided.As other local detailed description in detail of this specification, can be transmitted to the system element that influenced by described change then for these renewals of network data base, for example based on the section summary document (zone profile) in the navigation system of section.

Detect inconsistency and compensation automatically

In another kind of form of the present invention, detected inconsistency can compensate automatically, and need not involve network operator.

Fig. 3 shows and is used to detect the network inconsistency and by upgrading the system architecture that each network element compensates this inconsistency automatically.The wireless measurement of network 10 wireless signals is made by mobile radio terminal 20.These measurements are sent to location-server 30, can use the same mobile wireless network 10 of initial measurement to send.As describing before, location-server 30 handle measure and with its with database 50 in the data of storing compare.If the inconsistency of detecting, then location-server 30 is determined the influenced and definite adequate compensation to this inconsistency of which system element, to keep service, though this service can be attenuated potentially.Location-server 30 is to being subjected to described inconsistency influence and determining that each system element that compensates sends information.In particular instance shown in Figure 3, determining to be subjected to one or more inconsistent sex system elements can be a plurality of mobile radio terminals 20,20a, 20b and 20c.This comprises makes network measure at first and these is reported to the mobile radio terminal 20 of location-server 30.In this particular instance, mobile radio terminal 20,20a, 20b and 20c can be the groups that is associated with the particular section of a series of network measure definition.If exist inconsistency in network measure and database, this may influence the various services that are associated with that section.Therefore, offset data can be offered each mobile radio terminal to compensate this inconsistency.In PCT/AU2006/001479, describe in detail and can be used to multiple device and application program that a plurality of users and particular section are associated.

Fig. 4 shows and is used to detect inconsistency and upgrades affected system element automatically to compensate the handling process of this inconsistency.Processing begins at step 200 place, measures or detected inconsistency and in step 202 these and network data base 50 being compared at step 201 place collection network then.Which if in step 203, detect inconsistency, then determine in the influence that is subjected to this inconsistency based on the section summary document in the navigation system of section in step 204 place system.Described in other place of this specification and to be used to make such method of determining.In step 205, system compensates each as previously described like that and is subjected to this inconsistent sex section.In step 206, system determines the influence of the section summary document which user is upgraded, and in step 207, and the section summary document that upgrades is sent to each affected user, as above and with reference to unsettled PCT application described.This method finishes at step 208 place then.

A kind of compensation method is to use to ignore mark, and is such as described in more detail below.For many inconsistencies that identifies, system may not discern inconsistency basic reason behind, therefore may not adjust by rights.Therefore, the method that compensates inconsistency automatically is that affected single honeycomb or a plurality of cellular application are ignored mark.

Find out and be subjected to the section that network changes to be influenced

It is the needed any change that relates to the information of network of navigation system that network changes.Can to be navigation system be the result of the action that responds detected inconsistency and take in such change.Such change can be that the operator is upgrading and/or expanding in a plurality of renewals that provide owing to network configuration.Such change can be to one or more correction of response are provided by the mistake that exists in the network data that provides before the network operator.

Fig. 5 shows and is used to detect which section summary document and is subjected to the influence of the change of network data base 50 or is subjected to inconsistent sex handling process.This processing originates in step 300, obtains the data that change about network then in step 301.In step 302 and 303, this each honeycomb that is treated in each section summary document checks whether the honeycomb parameter in this summary document is subjected to the influence of described change or inconsistency.If honeycomb is affected and in step 305 this change be considered to significantly, therefore think in step 306 that so relevant section summary document is subjected to the influence of this change and is made a mark so that upgrade.In step 307, all section summary documents of having been done mark are collected further processing, send to the associated user of this section such as the section summary document after will upgrading, such as previously described.By determining influenced section and upgrading relevant section summary sets of documentation altogether, can obtain treatment effeciency like this.

In each execution mode, if there are many aspects in the network data base of storing in the described mobile radio terminal, then need to weigh send message for example SMS to each mobile radio terminal that is subjected to given variable effect with the cost that solves this change with ignore this change and the performance degradation of the navigation system that causes.If the given variation at given portable terminal or section summary document is considered to endurable to the navigation system Effect on Performance, should change just not remarkable so.

Any change to the identifier relevant with honeycomb is considered to significant.

Surpass threshold value if the signal strength signal intensity that honeycomb receives changes, the change that then influences this signal strength signal intensity that receives is considered to significant.This thresholding can be arranged in the following scope, and for example about 0dB to 9dB, about 0.5dB are to about 4dB, or about 1dB is to about 6dB.

Surpass threshold value if the signal strength signal intensity that receives changes, then will influence the change of regularly measuring and think significantly.This threshold value can be arranged in the following scope, and for example about 0m is to about 1000m, and about 10m is to about 50m, and about 20m is to about 100m, and about 50m is to about 500m, or about 200m is to about 1000m.

If the signal strength signal intensity that new honeycomb expection receives surpasses threshold value, then the existence of this new honeycomb is considered to significant.In GSM, this threshold value can be arranged in the following scope, and for example about-110dBm is to pact-80dBm, and pact-105dBm is to pact-95dBm, or pact-100dBm is to pact-90dBm.

If the signal strength signal intensity that honeycomb receives surpasses threshold value, then delete this honeycomb and be considered to significant.In GSM, this threshold value can be arranged in the following scope, and for example about-110dBm is to pact-80dBm, and pact-105dBm is to pact-95dBm, or pact-100dBm is to pact-90dBm.

One group network change may cause to given portable terminal or section summary document more than one change.Under these circumstances, what is that the significant definition that changes can be changed to so that think based on each honeycomb significant change outnumber threshold value the time all changes all be considered to significant.For example, if having two to the change of section summary document but this two changes all are considered to inapparent, think that then described combination is significant.This threshold value can be arranged in about 2 extremely about 20 inapparent changes.This threshold value also can be set to 2,3,4,5,6,7,8,9 or 10 inapparent changes in certain embodiments.

Do not propagated when giving system element when network changes, randomly described change is stored in the central server, with as to being stored in the increment of the baseline in the portable terminal.Can be stored in baseline evaluation change afterwards in the portable terminal according to this then, and make decision about conspicuousness according to this baseline.This has been avoided a series of less inapparent changes by accumulation with when the summation that is changed is considered to significant and be left in the basket.In addition, in office what is the need for when will send a message to portable terminal, storing of this increment is beneficial to all tangible changes of transmission.

, exist with propagation to change to the relevant minimum cost of each system element during in all information relevant by centralized stores with network.And might not be considered to the conspicuousness of the given change of given portable terminal or section summary document.Simple process and transmission are all carried out in all changes on request.

Utilize simulation to find and be subjected to the section that network changes to be influenced

Fig. 6 shows and is used to detect change or inconsistent sex another handling process which section summary document is subjected to network data base.This processing is similar to processing shown in Figure 5, except this pack processing includes network changes the influence widely of (particularly because the change that network is resetted and caused).The character of the multi-frequency channel among frequency reuse and the mobile network means that disturbing is a problem.No matter when have the change to network, the honeycomb that can hear in given place can change.In this respect of the present invention, this handles the influence of estimating all honeycombs on the section, and not only estimates the influence of those honeycombs that defined in the given section summary document.This processing also can be estimated the influence of the subclass of all honeycombs on the section.Usually, this subclass is confirmed as those and is positioned at the honeycomb that disposes the scope of distance with section apart.This configuration distance can change according near the density of the intrasystem cells the section.A kind of such method that is used for definite and the proportional distance of cellular densities is the multiple to the intermediate distance of adjacent cell, detects the PCT patent of inconsistency in common unsettled being used for of mentioning before and has described this method.These methods have such advantage, and the honeycomb that becomes and can hear owing to described change or reverse can be found in promptly former ground that can't hear certain honeycomb in section.

Begin from step 400, handle the information that changes about network in the acquisition of step 401 place.In step 402 and 403, for each section, this signal that is treated near this section of all cellular analog of this section receives.In step 404 and 405, near each honeycomb this section, this is handled and determines the influence of described change to described honeycomb summary document parameter.In step 406, make determining that the conspicuousness that whether changed about described honeycomb influences.If, then in step 407 the described section of mark so that carry out follow-up renewal.If not, then hold fire.In step 408, all sections that are labeled are gathered together so that carry out follow-up action.This processing finishes at step 409 place.

Because network changes and update system

Fig. 7 shows and is used for the system architecture of update system because network changes.No matter this change is to the correction of network data base or upgrades that this architecture all is identical.Network operator perhaps manually or by automatic system, will offer location-server 30 to the change of network 10.Location-server 30 is analyzed this network and is changed, and by getting up to determine which system element with this analysis with from the data combination of database 50, be mobile radio terminal 20,20a and 20b in this example, be subjected to the influence of this change, and any correction need be sent to each this system element.Via wireless network 10 one or more network updating message are sent to each this system element then.As mentioned above, may involve during this is handled or may not involve network operator 40.

Upgrade section summary document

No matter when have the change to network, section summary document all may need to upgrade.This change can be any combination of following change: network renewal that operator 40 provides or correction, application parameter as make by the operator or system makes automatically to the application of ignore-tag or removing, increase or deletion honeycomb or any other change that the summary document is updated, as this specification is specifically described.

Fig. 8 shows the processing that comes the section summary document in the update system based on changing.Each section summary document is carried out this processing to determine the influence of described change to the summary document.If have the change of determining to influence the zone detection performance, then upgrade the summary document.Like this, upgrade conspicuousness and the system architecture of the decision of summary document, as described herein based on described influence.

The update system element

For response to network upgrades, network is corrected or the change of the behavior of application, described system needs the update system element.This change can be order about by the Systems Operator or by ordering about of detecting based on inconsistency from dynamic response.Under the situation based on the navigation system of section, the system element that needs to upgrade is the section summary document of definition section.

Change is classified to network

Figure 11 shows the classification that network data base changes.How the classification of given change will handle change and will make what change to the navigation system element if having influenced.

The network data base change is classified as to be upgraded or correction.The change of the network configuration that the renewal expression has reflected in the network data base that upgrades.The network data base that initially provides that makes that exists in the expression network data base is provided is not reacted the mistake of real network configuration.

These change also can classify as interim or permanent.The correction that the mistake found to the permanent change of real network configuration or for response is carried out network data base has been reacted in permanent change.Iterim Change is to be caused by the environment in the certain limit.The example of this change comprises owing to the scheduled maintenance failure honeycomb of not operation provisionally, the volatile data base that is mounted short-term to increase the interim honeycomb of capacity and/or coverage and is used to compensate the also unidentified network configuration inconsistency that goes out of basic reason changes.Permanent change expression because network configuration changes the renewal that causes and to the correction of the mistake in the network data base.Expression is contemplated to the overwhelming majority that network data base changes to the permanent change of the renewal of network configuration.

Change the parameter that relates to unique and cellular marker non-uniqueness or influence the signal audibility or both for any given network data base of existing honeycomb.Cellular marker is to be observed the parameter that can not change wherein.Change to cellular marker requires any system element that influenced by this change is all made a change.Signal audibility parameter is to influence the signal level of given position expection and the parameter that the ability of signal can be heard in the given position.Change to the parameter that influences the signal audibility requires the observed signal of any energy to propagate, and as the time of advent or signal strength signal intensity, compensate based on each position.The parameter that influences the signal audibility comprises antenna azimuth, antenna downtilt, antenna height, antenna (honeycomb) position and transmitting power.Can handle change simply by only considering influence that given change receives signal to the parameter that influences the signal audibility.For example, if the honeycomb transmitting power increases 3dB, the expection signal strength signal intensity of so any position should increase 3dB.The more exact method of determining the influence of change is other wireless signal of considering in interior same wireless channel of the honeycomb environs that upgrades and the adjacent channel.Utilize same instance, the increase of power level will increase the interference to other honeycomb in same channel and the adjacent channel.In the given position, this increase of interference may make another honeycomb not be heard.On the contrary, the increase of power make the given position honeycomb can hear and before honeycomb can not hear.Cell ID, part identifier (for example, the BSIC among the GSM) and the change of tranmitting frequency are influenced signal identification.It will be understood by those skilled in the art that the first approximate sign changes the change that can be considered to influence with those signal audibility and has nothing to do.If adopted above-described more accurate method, some parameter changes will influence cell identities and signal audibility so.Particularly, the wireless channel as tranmitting frequency is the identifier of nonuniqueness and also influences the signal audibility.

Adding honeycomb to network need determine the effect of new honeycomb and upgrade affected system element provisionally or for good and all with new honeycomb.Honeycomb may be because fault, scheduled maintenance or the inoperation because honeycomb has withdrawed from use.Need be updated with affected honeycomb system associated element.

Also having a kind of change is to revise the apply property that is associated with honeycomb.The example of this attribute is included in other local ignore-tag of describing of this specification, expired time and the short ID fuzzy mark as in PCT/AU2006/000478 describe relevant with honeycomb or application parameter.

Determine affected section

Network data base upgrades and corrects and need be transmitted to system element, section summary document for example, and this system element is subjected to the change influence of single or multiple honeycombs.The first step is to determine which system element is affected.

In certain embodiments, can estimate each system element to determine whether influenced system element for the change of given honeycomb.In other embodiments, evaluation that at first will be more rough is handled and is used for definite those system elements that are subjected to the change influence of given honeycomb potentially, and whether each that estimate then in those system elements has influence on that system element with change of determining given honeycomb.Change among the embodiment that effect to each system element is complicated calculating estimating given honeycomb, this has the minimized advantage of the computing cost of making.The example that rough evaluation is handled is to determine that those are at new honeycomb or revise the system element of (as shown in figure 12) in the scope of predetermined radius of honeycomb.Radius is illustrated in given network configuration and allows the system element position that new honeycomb under any probabilistic situation is arranged or revise the expection maximum magnitude of honeycomb.That radius at about 50m to about 50km, from about 50m to about 35km, from about 100m to about 1000m, change from about 500m to about 3000m or in the scope from about 2000m to about 10000m.In certain embodiments, in whole network or in some part of network this radius to be treated to constant be desirable, in other embodiments, be desirable based on each honeycomb treatment radius, and In yet another embodiment, be desirable by coming treatment radius with the compound mode of upper type.For example, if the expection maximum magnitude that honeycomb has is 5000m, and section location is accurate to 500m, and the search radius that is subjected to the system element of new honeycomb influence so is 5500m at least.

It is search technique under the situation of wireless summary document of definition space section that Figure 13 shows at system element.Section is marked as Z1 to Z6.Come the nominal position of mark section with stain.The search of finding section Z2, Z3, Z5 and Z6 with honeycomb in the scope of R.

Determine which section is subjected to the method that given network changes influence and is to use radio transmission model to determine whether can hear honeycomb new or that change in the position of given system element, as shown in figure 13.Such propagation model is well known in the art, compiles Mobile RadioCommunication, Hata the 2.7th chapter of second edition, ISDN 047197806X, J.Wiley ﹠amp as Steele and Hanzo; SonsLtd, 1999.If comprise also that more than the reference noise of receiver and in model the summation of interference and these all interference of interference ratio is all high a lot of if estimate the signal level that receives, then expection can be heard given honeycomb in the position of given system element.As disclosed among the PCT/AU2006/001479, system element such as section summary document can have relative position, and perhaps the measurement of making at this system element place of Shi Yonging has the estimated position of this system element of calculating.Such position, what no matter provide still calculates, and can have an inexactness in various degree.This may owing to system element for example further from problematic honeycomb or more influence the audibility of given honeycomb near the such effect of interference source.In certain embodiments, can make amendment with the uncertainty of compensation location to examination criteria.A kind of such compensation method is the threshold value that reduces the receiver reference noise, thereby thinks that potentially honeycomb may be heard, but is considered to below reference noise at this honeycomb before.Compensation is to reduce the about 0dBm of reference noise to about 10dBm, about 0dBm about 2dBm, about 1dBm about 3dBm or about 2dBm about 6dBm extremely extremely extremely.

Figure 13 shows the search technique under the situation of wireless summary document that system element is the definition space section.Section is marked as Z1 to Z6.Come the nominal position of mark section with stain.The definite border that can hear the scope of honeycomb of wireless simulation.Find the search of section Z2, Z3 and Z5 in the wireless coverage of honeycomb, to carry out.

As described in the patent application of the common submission of describing detection method, pass to the message of server from portable terminal, for example section state updating message can have and section state update group wireless data altogether.For the expression of given section from going into to going out transformation or the section state updating information of opposite transformation the wireless data of representing section is provided.After network was changed, location-server can be analyzed these wireless datas and determine network changes whether section summary document is had any influence.Location-server can be determined: if comprise new honeycomb in wireless measurement, then section summary document is subjected to the influence of that new honeycomb.Location-server can be determined: if the honeycomb of can't hear in section before has been included in the wireless measurement, then section summary document is subjected to the influence of one or more changes that honeycomb become can hear.By being given section accumulation wireless data, location-server can be determined no longer can hear the given honeycomb that comprises in the section summary document because one or more network changes in section.This data accumulation can realize that this technology is used to detect the not operation honeycomb but the data limit of checking is arrived and the relevant data of particular section summary document by disclosed technology in the described patent application of using common submission.Selectively, location-server can only be analyzed and relate to those and be determined and will have been changed the data of the section summary document that influences potentially, and wherein, this change is handled to determine by using rough technology described herein and being used for search refinement then.

Existing honeycomb

Directly influence among some embodiment of the honeycomb that has existed in the network data base in the network change, the system element that is subjected to the influence of honeycomb parameter change is to determine with those system elements that the honeycomb that changes is associated by search in network data base.

The network of the honeycomb that has existed in network data base changes among some embodiment of the signal level that can influence the system element reception, and the system element that is influenced like this is to determine to determine the influence which system element is changed by the simulation of using wireless network.

Such network change includes but not limited to the use of withdrawing from of honeycomb, is detected at given system element place because remove the signal that is interfered before honeycomb can make it.Other change that can influence the signal level that receives includes but not limited to frequency, antenna parameter and transmitting power.Selectively, the honeycomb that relates to can be only considered in simulation in system element.Selectively, system can file the parameter that is associated with the honeycomb that no longer can hear at given system element place, conveniently to reinstall the honeycomb in the given summary document, as long as later change can make honeycomb can be heard once more.

Illustrated in following example and determined which system element is subjected to the processing to the influence of the change of honeycomb, in following example, system element is a GSM section summary document.Network changes has caused cell ID 54763 to be changed into 33932.Affected section summary document is by search system, comprises that promptly the database of any section summary document of cell ID 54763 is determined.In the above table 3 that illustrates, will find such section summary document by this processing.

In another example, the ARFCN of honeycomb 892 and BSIC are changed.New ARFCN is 76, and new BSIC is 18.Again, the set of searching for existing section summary document at those cell IDs that relate to 892 is to determine to be subjected to the set that this changes the section summary document of influence.

In another example, the transmitting power of honeycomb 18322 is reduced 3dBm.Again, the set of searching for existing section summary document at those cell IDs that relate to 18322 is to determine to be subjected to the set that this changes the section summary document of influence.

In certain embodiments of the present invention, being independent of those parameters that influence signal strength signal intensity changes cell identities and handles.Being subjected to system element that cell identities changes influence and being the data that the element search of the honeycomb by relating to change at those is associated with system element determines.

Determine the change of the signal strength signal intensity that receives of the existing honeycomb of influence.Can follow the same processing that search relates to the section summary document of the honeycomb of revising because like this, discern affected honeycomb.This same processing can be applied to removes the honeycomb that uses.

New honeycomb

Can accurately do not known during signal in not measuring that section of the audibility of the new honeycomb in the given section and signal level.Because user's the inconvenience and the potential load of system, and unnecessary hope makes the user set up new registration procedure section.The replacement method of setting up new registration procedure section is to use radio transmission model to determine to hear the system element at new honeycomb place.

With cellular marker for being left in the basket

In one aspect of the invention, existing the cellular marker in database and other system element is with uncared-for mechanism.When honeycomb is marked as when being left in the basket, navigation system does not comprise the measurement from that honeycomb in the correlation computations of any location.

When having database-network inconsistency, " ignoring " tagging mechanism to the maintenance system performance of great use.In case the inconsistency of detecting then can be to affected cellular application ignore-tag, change with the database update or the network configuration of carrying out any needs up to identifying basic reason or obtaining suitable data.Such ignore-tag provides the method for rapid handling problem, and does not need actual dealing with problems.An example is to detect unknown honeycomb by navigation system.As discussed earlier, this may comprise existing in new honeycomb or the database having typing error because of multiple reason.Up to identifying before the actual cause, the data about " new " honeycomb of collection are used for creating the clauses and subclauses of network data base, and these clauses and subclauses are marked as and will be left in the basket.Change and be transmitted to all affected system elements.In case this problem is solved, then these clauses and subclauses in the database are removed.

" ignoring " tagging mechanism also has and can stand to the change of network data base with to the advantage of the time difference between the change of network configuration." ignore " inconsistency that mark can be used for compensating expection, but the duration of this inconsistency shortage short or information has hindered the suitable data storehouse to upgrade.Ignore-tag can be arranged to application before the network configuration of reality changes, and be arranged to after network configuration is resumed and be removed.For example, when honeycomb was arranged to turn-off a period of time for scheduled maintenance, the precise time that honeycomb will be turned off and keep out of the way will not be known once more.Ignore-tag is arranged to be employed in the past in the expection turn-off time the earliest, and is arranged to after the time is opened in expection the latest and is removed.

Exemplary use to ignore-tag comprises: interim honeycomb, and wherein the position of this honeycomb or this honeycomb correct time that is used and removes use can accurately not known; Be detected but for its deal with problems required information and unavailable inconsistency; The honeycomb of interim not operation.

By using the method for describing among the PCT/AU2006/000478, the effect of ignore-tag can be counted roughly like this: in the summary document for the bigger sigma of honeycomb distribution, so that the cost that is associated with honeycomb can be ignored.The value of sigma in the present context can be approximately greater than 10dB, approximately greater than 15dB, approximately greater than 25dB, approximately greater than 40dB, approximately greater than changing in the 60dB scope.

The action of Time Triggered

Renewal to system element can be configured to be triggered by the time.Before network configuration was changed, system can pre-determine the effect of this change and implement this change at the special time place, and it is identical with the planned time that changes network configuration that this special time is designed to.The example of this change to system is the planned maintenance of base station.The change that the honeycomb of NOT-AND operation is associated can be used at the fixed time automatically, and can reverse this change when base station expects return.

The Time Triggered device also can be used for reversing the application parameter that comprises ignore-tag and section registration permission.For example, as other place of this specification is described, can be to the cellular application ignore-tag of not operation.Utilize above example, can use ignore-tag to the honeycomb in the maintenance, and this ignore-tag is configured to reset in particular moment.Another example is the permission that registration section in the given time period is provided for the user.This permission can be cancelled automatically at predetermined instant.

The Time Triggered device can be realized in portable terminal or realize in server.Under latter event, server will send order to carry out any action that the portable terminal place requires, with the result as triggering to any portable terminal.

The Event triggered action

System can be configured to take when detecting certain incident special action to change with influence, thereby safeguards the consistency of the network data base in the whole system.Such incident comprises and detects new honeycomb, detects the not operation honeycomb that turns back to service state and detect new honeycomb when in section.

When detecting any inconsistency, system can take one or more following actions:

But the reporting system operator of-system has detected the network of configuration and the database that provides between inconsistency.This notice can randomly comprise the details of the character of inconsistency, for example, and detected new honeycomb and just cause details in the measurement of detected inconsistency.

-system can determine which section summary document is subjected to the influence of inconsistency.For such section summary document, affected cellular marker becomes will be left in the basket, and the summary document after will upgrading sends to all portable terminals that depends on this section summary document.

A kind of execution mode is the inconsistency that no matter when detects any kind, all adopts above dual mode.

Can adopt these to move and respond any inconsistency.Except these actions, following chapters and sections have been described in further detail the action to the inconsistency special use of certain type.Such action can independently be used or be used in combination with above one or more actions.

Based on the navigation system of section when detecting new honeycomb renewable potential affected section summary document to ignore this new honeycomb.Based on navigation system renewable potential affected section summary document when detecting new honeycomb of section, if when portable terminal is in that section, to detect new honeycomb then announcement server.Randomly, portable terminal can comprise the measurement to new honeycomb, as the signal strength signal intensity that receives.This has the advantage that can accurately determine can hear new honeycomb in which section.Then, server can be implemented one or more following actions:

-system can determine which section summary document can hear new honeycomb potentially for.Add new honeycomb to such section summary document, ignore-tag is set simultaneously.Use ignore-tag to mean that system can't require the exact value of all parameters of section summary document needs.

-system can use the report measurement of new honeycomb and optional other honeycomb or analogue measurement or above the two combination, thinks that section produces new wireless summary document, then, new section definition is sent to the user that all depend on this section definition.

-system can permit the portable terminal of one or more use sections to remeasure this section, so just accurately catches the signal level of new honeycomb, thereby makes new section summary document can be generated and be sent to all affected portable terminals.This is preferential selection, because its institute that has captured the network configuration change produces effect.

Exist potential unknown honeycomb if portable terminal has detected, then portable terminal can add honeycomb in the affected section summary document to based on getable measurement, and to that cellular application ignore-tag.Portable terminal can this detection of announcement server.Portable terminal rewritable area section state.These actions are not exclusive mutually, and can use with any order in any combination.

Handling with ignore-tag under the situation of not operation honeycomb, navigation system can be taked one or more following actions detecting when honeycomb is operated once more:

-portable terminal is detecting the ignore-tag of can resetting when honeycomb is operated.

But-portable terminal is announcement server when detecting the honeycomb operation.

-server renewable all cellular marker is become uncared-for portable terminal.

Under the situation that detects the inconsistency that relates to cellular marker, uniqueness and/or nonuniqueness, system can take one or more following actions:

-system can determine that those section summary documents are subjected to the influence of inconsistency.For such section summary document, affected cellular marker become will be left in the basket and will upgrade after the summary document send to the portable terminal that all depend on this section summary document.

If-have enough about the data of the reformed parameter that from network operation, obtains and correct inconsistency automatically, server can be determined affected section summary document, and the summary document that will upgrade after each section summary document also will upgrade sends to each portable terminal that depends on each summary document.For example, send but on ARFCN43, be heard by ARFCN 28 if having the honeycomb expection of cell ID 52415, server renewable all relate to the section summary document of cell ID 52415 so that ARFCN is changed over 43.Those of ordinary skills should be well understood to other cellular marker that how this is applied in GSM and other wireless access technology very much, and other wireless access technology for example is CDMA (IS-95), UMTS and CDMA-2000 etc.

Upgrade affected section

Following chapters and sections have been described section summary document definition because how the network change is upgraded.Have the change that to make network of many types, and each this change all there is discussion to the influence of section summary document.Can walk abreast to this change of network and to make.For example, honeycomb can make transmit power level and antenna downtilt tiltedly be changed simultaneously, and BSIC and ARFCN that the GSM honeycomb can have it simultaneously change.Those of ordinary skills should be very clear, can at first determine the cumulative effect that the group network on given section changes, and then new section summary document sent to each affected mobile phone.This has the advantage of the number that minimizes the message that sends to phone.

Handle Iterim Change

Need make Iterim Change and by this change being propagated into the scene of system element Iterim Change network data base to network thereby exist.Such scene includes but not limited to: safeguarded failure or experiencing the honeycomb of maintenance and honeycomb is being set to support the capacity requirement of short-term temporarily.Also exist following such situation: the difference between network data base and the actual disposition is found, and has perhaps made the network change, but changes the more required still part or all of non-availability of information of new database for this network.Following chapters and sections have described the method for the interim reparation that is used to realize inconsistency in detail.This reparation can be used automatically by server, as described in other place in this specification, and perhaps can be by Systems Operator's manual application when receiving notice or knowing this inconsistency by alternate manner.

Reverse and change

A kind of mode of handling Iterim Change is that network data base is made a change and this change is propagated into system element, submits to another to change to reverse this initial change subsequently.If honeycomb is interim not operation, then this honeycomb is removed and is propagated into all affected system elements from database.In case honeycomb is operated once more, then database is upgraded once more and the honeycomb of this deletion is reused.The data that this method requires to be associated with honeycomb are filed, thereby make can obtain such data when needs are reused these data.If prematurely honeycomb is removed from database, then honeycomb can be reused in database, and will change propagation to all affected system elements.Be disengaged use in case confirm honeycomb, then this honeycomb removed from database and it is propagated into all system elements.If interim honeycomb has been installed, then this honeycomb can be added in the database, and change is propagated into all affected system elements.In case the needs of honeycomb have been stopped and honeycomb is switched off, then this honeycomb can have been removed from database and other affected system element.

Cellular marker is become will be left in the basket

Be not that all types of network inconsistencies between configuration and the database can both reverse this inconsistency subsequently or otherwise solve this inconsistency in the time after a while and solve easily by change being propagated into system element.Can from database and other system element, remove inconsistent honeycomb, but they move in network still, and from the angle of navigation system, these inconsistent honeycombs will be that new honeycomb occurs as them.All measures of having taked are the influences that are used to change the character of described consequence and readjust these consequences when possibility.In addition, system is also with this new inconsistency of Final Report.

Solve the data that inconsistency requires to obtain to be used to correct inconsistency by upgrading network data base, and this needs to determine the basic reason of problem and determines correct change.In addition, network data base being made any change and will this any change propagate into time of affected system element need be consistent with the actual time that changes of network configuration.

The use of " ignoring " mark of not operation cellular application is based on use to section summary document illustrates by the zone detection system.This example uses the summary document that has defined section as shown in table 6.

In this example, can obtain one group of new measurement, as shown in following table 7.This measurement can be made in the section that it has been defined the summary document.For the honeycomb that service is provided, ARFCN and BSIC are unavailable, because do not report them in the NMR data.Honeycomb 25068 in measurement, do not occur, do not sending because this honeycomb is current.

As described at PCT/AU2006/000478, by will with the corresponding cost of the honeycomb sum up the costs of adding up coupling, unmatched and not report.Following Fig. 8 shows the value that goes out of honeycomb cost calculation for coupling, and this value representation is to 2 significant digits.

In this example, be not fully generally to use owing to use the measurement of the method for describing among the PCT/AU2006/000347, therefore use the not threshold value-105 of report.The value that calculates for the honeycomb of not reporting has been shown in the table 10.

Table 10

Cell ID	ARFCN	BAIC	Summary document RxLev	Threshold value	Cost
						25068	95	38	-60.0	-105	15.07

The strongest honeycomb is that the cost of honeycomb 25068 is the very high parts 15.07 in the total cost 15.26 in the summary document of losing from the measurement group.Whether in section, this cost has proved this portable terminal very significantly not in section, and according to the zone detection threshold value, this portable terminal can be declared beyond section about the decision portable terminal.State that because of the honeycomb of not operation portable terminal is not gratifying beyond section.By the honeycomb in the summary document 25068 is used ignore-tag, the total cost of measurement group is 0.19, and portable terminal is clearly in section.Begin operation in case honeycomb becomes, thereby then ignore-tag can be reset and makes zone detection operation and performance can turn back to normal condition.

The ignore-tag of using with the honeycomb of the unknown

The use of " ignoring " mark of unknown cellular application is based on use to section summary document illustrates by the zone detection system.This example uses the summary document of section shown in the above table 6 of definition.As other local explanation in this specification, the problem that detects unknown honeycomb can many reasons cause, comprise: the new honeycomb that becomes operation, in database, changing and do not having the correct cell identities parameter of upgrading and be scheduled to and removing the honeycomb that uses and from network data base, remove prematurely.

In this example, newly measure for one group that can obtain as shown in the following Table 11.Can not get ARFCN and BSIC for the honeycomb of serving, because in the NMR data, do not report them.

Near the honeycomb 25068 that service is provided, system do not find any coupling ARFCN be 84 and BSIC be 14 honeycomb.So in the network of network data base and configuration, have inconsistency.Simultaneously, because therefore this honeycomb and the summary document that do not match hear that the cost of unknown honeycomb is 9.68, as shown in Table 12.This representative has clearly evidence to show that described portable terminal is not in section and can obviously influence the performance of zone detection.In case system detects the existence of this unknown honeycomb, then the details of this honeycomb can be added in each affected section summary document, and ignore-tag is set.In case determine the basic reason of inconsistency and obtain the required data of update system, then use the affected summary document of correct information updating, the temporary information that the mark that is left in the basket is contained is removed.

Distinguish network renewal and correction

When sending to system element when new database more with change, preferably having what be associated with each change is the indication of correcting or upgrading about change.In Utopian network, change is with the change recently that is updated with the reaction pair network configuration.Experience shows, has mistake between the network of network data base and reality.Correction is the change of the detection of this mistake being made for response.In both cases, all be necessary to upgrade network data base.According to the updating type and the system type of navigation system, may wish automatically or otherwise to upgrade all system elements and correct with response.The classification of type of database update is helped improving network change processing.

Difference between renewal and the correction below has been described.In an example, there is such navigation system, in this system, defines this section, thereby produce the summary document that provides in the following table 13 based on the actual measurement in the section based on section.After the definition of this section, find that the transmitting power about honeycomb 54763 and 18322 that network data base has is-33dBm, and this transmitting power should be-30dBm.This change will be marked as correction, because this change is not associated with the change of the physical configuration of network.Owing to be based on the actual measurement configuration for 54763 summary document entry, so the mistake in the database can't influence this summary document entry, thereby should not change to propagate and give these section clauses and subclauses.On the contrary, be based on the signal level of prediction for the summary document entry of honeycomb 18322.A parameter of prediction will be a launching electrical level.Because the level 3dB on the low side that uses, so the RxLevMean summary document entry of honeycomb 18322 is with 3dB on the low side.This summary document entry should be upgraded.

Readjust the transmitting power that causes honeycomb 54763 and 18322 at network from-30dBm to the-true change of 33dBm and under the different situations of other change, database changes will be marked as renewal, because in fact the signal that has weakened 3dBm has all taken place to change and now just sending two honeycombs.Because it is real changing, rather than fault causes, so all section summary documents that comprise one of them or two honeycombs all should be updated.For the summary document of definition in the table 12, honeycomb 54763 and 18322 RxLevMean will be changed over respectively-91.3dBm and-95.1dBm.

The application of this respect of the present invention that changes for networks of different type will be described in the chapters and sections after a while of this specification.

Sign changes the Vs signal level and changes

Any given change in network data base, ignore new honeycomb and ignore the honeycomb of deletion and can be classified as the change of the signal level that the change that influences cellular marker or influence receive to the renewal of network data base.

The change that influences identifier can easily be upgraded, and edits change with the reaction identifier because only must relate to existing data in the section summary document of described honeycomb to each.Such identifier comprises cell ID, signal frequency and and nonuniqueness identifier.For example, the GSM network data base is readjusted and is updated owing to network.For cell ID 45241, ARFCN (frequency) becomes 53 from channel 32, and BSIC (identifier of nonuniqueness) becomes 16 from 53.Neglect the possible effect of interference, each section summary document that relates to honeycomb 45241 all is updated to has new ARFCN and BSIC.

Handle nonvolatil change

Usually, most of network change is permanent change.Permanent change represents that this change expection can be used to tie up continuous network state and reaction network state.This is opposite with provisional change, provisional change represent this change expection be relative transience and will be reversed by permanent change or replace.Being used for of this paper discussion upgraded network element because of permanent change technology can be used for handling some provisional change, thereby this provisional change is reversed when provisional condition stops.

Change to existing honeycomb can be categorized into change that influences cellular marker or the change that influences the signal level that receives usually.According to wireless network type, frequency can be used as cellular marker, is used as the parameter that influences the signal level that receives, or these two.

Identifier changes

The change that influences identifier can easily be upgraded, and edits change with the reaction identifier because only must relate to existing data in the section summary document of honeycomb to each.Such identifier comprises the identifier of cell ID, signal frequency and nonuniqueness.

For example, the GSM network is updated.One of them change is originally to have the honeycomb of cell ID 54763 to have cell ID 33932 now.Table 12 shows one of them and is changed the wireless summary document that influences.In order to compensate this change, cell ID 54763 is changed over 33932, to upgrade section summary document.

In another example, the GSM network is updated.One of them change is for honeycomb 892, and ARFCN (frequency) becomes 76 from channel 71, and BSIC (identifier of nonuniqueness) becomes 18 from 61.Table 14 shows one of them and is changed the wireless summary document that influences.Change in order to compensate this, the ARFCN and the BSIC that are associated with cell ID 892 are updated to new value, to upgrade section summary document.

Signal level changes

To transmitting power, antenna type, antenna azimuth, antenna downtilt tiltedly and the change of antenna (honeycomb) position can influence the received signal level at system element place.The net change of the through-put power of propagating on the direction of system element that can be by determining to come cellular autofluorescence is upgraded the data that are associated with system element, and update system element correspondingly subsequently.How the change that following chapters and sections have been described different parameters solves, and wherein system element is a section summary document.When power is to be unit when measuring with dB, and change is an additivity.For example, if honeycomb increases 3dB and scope angle 5 degree that turn clockwise with transmitting power, so the change of system element be increase that 3dB adds since antenna towards the change that causes.

If the transmitting power of honeycomb 45241 has increased 4.5dB, all comprise that the section summary document of the received signal intensity of honeycomb 45241 need increase 4.5dB with the expection received signal intensity of honeycomb 45241 so.So the section summary document that relates to honeycomb 45241 will expect that received signal intensity-78dBm is updated to-73.5dBm.

When the antenna azimuth changed, effect was that emitted power uprises on some direction, and on other direction step-down.When the position of section summary document is not in the main lobe at antenna, change remarkable especially.

The processing that is used for the effect of definite antenna azimuth change is to find before the change and the difference between the antenna gain of section summary document after changing.Can obtain according to the specification of this antenna manufacturer or by the universal model that uses antenna with respect to the antenna gain on the assigned direction of antenna boresight (antenna boresight).In case calculate antenna gain difference, then need to use change towards section.Figure 14 shows the model of the horizontal antenna pattern of the honeycomb represented with solid line circle and honeycomb.The antenna boresight energized north.The gain of this antenna on sight line is 12.4bBi.The antenna gain of pointing to the section that is expressed as section 1 of spending with antenna boresight skew 10 is 11.6dBi.The antenna gain of pointing to the section that is expressed as section 2 of spending with antenna boresight skew 100 is-8.6dBi.Figure 15 shows the honeycomb that antenna is pointed to the point of 10 degree from the north by west again.The result is that the gain of pointing to section 1 is 10.6dBi now, has reduced 1dB.Like this, the signal level of section 1 place expection reduces to-76dB (table 16) from-75dB (table 15).The gain of pointing to section 2 is-13.1dBi to have reduced 4.5dB now.Like this, the expection signal level at section 2 places reduces to-98.4dB (table 18) from-94dB (table 17).

Except the vertical gain mode of antenna is used, the adjustment of the oblique change of antenna downtilt is similar to azimuthal change.Have a down dip adjust before and afterwards difference towards the vertical antenna gain of section summary document be applied to the expection signal strength signal intensity at section summary document place.

The adjustment that antenna model is changed is similar to azimuthal change.Difference to level on the direction of section summary document and vertically gain is calculated, and this difference is applied to the expection signal strength signal intensity at section summary document place.

Adjustment to antenna height has two effects.At first, the change of height has influenced the vertical gain of given system element, because with respect to the vertical angle of system element change has taken place.Identical for the account form of this influence of system element with technical approach about the change that has a down dip.

The second, the change of height can change the expection signal level that receives at given system element place.When being to use radio transmission model at the received signal level at this system element place of estimation before the antenna height change and in new high degree, this method estimates the received signal level at this system element place once more.Then the difference between two estimations is applied to this system element.Randomly, radio transmission model the increase that terrestrial information produces owing to the change of antenna height with the coverage considering honeycomb and provide is provided or reduces.Randomly, radio transmission model will comprise that also interference is to the influence of other signal with in the audibility of other honeycomb at the system element place that considers and other system element place.

Horizontal gain can be influenced to the change of aerial position, the change of antenna model, antenna height and the scope of system element can be comprised towards the vertical gain of system element towards system element.Technical description described above how to handle except the change of scope the institute produce effect.The change of scope is adjusted to by using radio transmission model to estimate in given system element position because the difference of the received signal intensity that the change of scope causes.Then the expection received signal intensity at this system element place is used this difference.This method is similar with the method that is used to adjust the influence of intensity highly to received signal.

In some cases, when the effect that exists some with the change of prediction cellular configuration be associated uncertain the time, also be necessary for affected summary document element adjustment sigma.As an example, consider to relate to the change of cellular antenna being reorientated 100 meters.In the case, the wireless channel between honeycomb and the section can have significantly different shadow fading.It is known that such effect is propagated in the field of simulation at mobile wireless, and wherein, the correlation of the shadow fading between 100 meters two acceptance points of being separated by is approximately zero usually.Therefore, after having adjusted rxLevMean according to simulation, by the current example of use with cellular antenna offset 100m, thereby the sigma of honeycomb 25068 should be increased the bigger uncertainty that reaction is associated with the average rxLev of summary document.As an example, can use increase 3dB.

Change under the very big situation in aerial position, if affected section summary document also is the feature of signal timing element, these signal timing elements also must be updated.

It is to determine by the influence of accumulating each change independently that a plurality of network configuration change the influence of intensity to received signal.When the difference of received signal intensity be with dB be unit measure the time, accumulation is addition simply.For example, if the transmitting power of honeycomb 45241 increases 4.5dB, and thereby the antenna azimuth of this honeycomb is rotated counterclockwise 10 degree and makes the signal strength signal intensity of system element estimate reduce 1dB, and the influence about the 45241 pairs of system elements of honeycomb that come into question is that the expection signal strength signal intensity increases 3.5dB so.

The substitute mode that the effect that will change the difference of honeycomb is progressively accumulated is to use the radio transmission model that combines all parameters.Such model can comprise the influence to the given signal audibility of given position of cochannel, adjacent channel and replacement channel disturbance.Model can be at before changing and the network operation after changing.Then the difference between the received signal intensity is applied to section summary document.This method has calibrated analog effectively and accurate signal intensity more can be stored into advantage in the summary document.

The advantage of this method is can detect the network that causes existing or new honeycomb to become being heard to change in section.

Confers similar advantages is can detect to cause existing honeycomb owing to the expection signal level is reduced to receiver ground noise or the following network change that becomes and can't hear of unnecessary noise in section, and such network changes the existence that comprises new honeycomb.

If honeycomb is considered to be interfered and thereby no longer can be heard, preferably make honeycomb in the section definition have renewal the section defined parameters but with cellular marker for uncared-for honeycomb.That is to say that can this honeycomb it be heard and do not considered by the zone detection algorithm.One of them advantage of doing like this be honeycomb still in section definition, but network in the future changes and no longer disturbs this honeycomb.Another selection is that the honeycomb that will be disturbed is removed from the section definition.This will reduce the quantity that need carry out the zone detection algorithm process to each iteration.Another selection is the tabulation that is maintained in the honeycomb that can hear in this section but can not be heard for each section under the situation of given current network configuration, and the section parameter relevant with them.When making the future network configuration change in the future, network analog thinks that the honeycomb in section summary document, the honeycomb in the tabulation is be evaluated as the candidate's honeycomb that comprises in the section summary document.

If can in described section, can hear owing to the change to network becomes honeycomb, then this honeycomb can be adjusted to and use the technology identical technology used with the honeycomb of up-to-date use, in other place of this specification this technology has been described.If the honeycomb that can hear in section is removed owing to previous network changes before, then under the prerequisite that the section summary document parameter that is associated is retained, this honeycomb can be reset in the section summary document.Restore this honeycomb with the parameter value early that is adjusted to the change between the network configuration that adapts to early and the new network configuration suitably.

New honeycomb

When new honeycomb is used, this honeycomb is added in the section summary document of the definite any section that can be heard potentially of new honeycomb.This may reduce the performance of zone detection, will be used as unmatched honeycomb and treat because if new honeycomb confirms to be heard then it.Usually, upgrade section two steps are arranged owing to the existence of new honeycomb.First step is to determine which section needs to upgrade.Second step is to take to upgrade the action of section, so that the existence of new honeycomb is compensated.

Figure 16 shows the handling process of the existence that is used to handle new honeycomb.This processing originates in step 800, and after this step, this processing receives the information that new honeycomb has been detected.At step 801,802 and 803 places,, determine whether section summary document is subjected to the influence of new honeycomb for each section.If then in step 804, upgrade section summary document, and the summary document after step 805 will be upgraded sends to the mobile radio terminal that each uses section.This processing finishes at step 806 place.Manage with database 50 in step 802,804 and 805 everywhere and to carry out alternately with comparing data and new data more.

Following method has been described and has been used for determining which section is subjected to the means of the influence of new honeycomb.These methods can according to the audibility of signal in the section or according to section with the state that closes on of new honeycomb from broadly classifying.

Renewal is considered to be subjected to the section of the influence of new honeycomb

Determine that new honeycomb is to remeasure section to a kind of method of the influence of section summary document, the received signal level that so just can not only capture new honeycomb can also capture the influence of new honeycomb to the audibility of other honeycomb in the section.User's transmission to each such section requires the user to set up new registration procedure the text message of section.In PCT/AU2006/001479, the method that is used to control section registration permission has been described.If adopt this method, then location-server can send message to the user of each affected section, to make things convenient for the section registration.

Another method is to add new honeycomb to each section that has been considered to be used the new honeycomb influence of ignore-tag.This has guaranteed can not influence the zone detection performance in the existence of considering the stylish honeycomb of unmatched honeycomb.Yet as long as it cannot report other known honeycomb to portable terminal to the report expression of new honeycomb, the existence of new honeycomb will influence the section performance.

The variant of ignore-tag is to use it as the means of determining can hear new honeycomb more accurately in which section.If mobile radio terminal in section and its can hear new honeycomb, then mobile radio terminal is sent to a message, this message informing user hotline need be set up new registration procedure.This can finish by utilizing the software in the mobile radio terminal.This also can finish by mobile radio terminal and server, and this mobile radio terminal sends message to server, and this server is used to messages sent by users and responded and use when needed the permission of response registration section.In this mode, overcome before setting up new registration procedure and to have waited for that mobile radio terminal reports the shortcoming of new honeycomb.Before the moment that section is set up new registration procedure, the influence by using ignore-tag with new honeycomb minimizes.This method also have can in section, detect at any time new honeycomb rather than only in the section transition trigger section state could detect the advantage of new honeycomb when upgrading.Become effectively back a period of time at new honeycomb, for example 30 days, described section, detect less than removing new honeycomb in the section of described honeycomb from any.This has been avoided section summary document to be upset by unnecessary honeycomb.

Another method of upgrading section summary document is to add honeycomb to think to those and be subjected in the section of signal level influence that this signal level draws by utilizing analogue technique to derive.As previously mentioned, the use of signal strength model is depended on estimation to section position.

For example the signal strength model of Hata can be used for estimating the new cellular signal strength in the given section.The output of this model is normally coarse, because model can't be considered the certain effects of the propagation path between transmitter and section, this is known in the art.In order to compensate this inexactness, the signal strength signal intensity standard deviation relevant with honeycomb can be increased.This increase can be at about 0dBm to about 18dBm, and about 0dBm is to about 3dBm, and about 1dBm is to about 5dBm, and about 3dBm is to the scope of about 9dBm.Any difference between the signal strength signal intensity of this signal strength signal intensity that causes the measured place and expection is estimated lower cost.If there be the uncertainty relevant with section position, then can increase change in signal strength can compensate.

Under new honeycomb and the juxtaposed particular case of existing honeycomb, for example, the honeycomb of a 1800MHz is installed on the place of the honeycomb that only has 900MHz before.In this case, use simulation to estimate the receiving intensity of two honeycombs and calculate difference.Then this difference is increased on the signal level in the section summary document of existing honeycomb to obtain the value of new honeycomb.In fact, the existing signal level in the section summary document is used to calibrated analog.Because the shadow fading between honeycomb and the section can be owing to shared transmission path has very strong correlation, so this method can work.For example, the signal strength signal intensity that has of the honeycomb 55615 in the section summary document is-85dBm.Install new honeycomb 45615 at identical place, place.The low 6dB of the expection signal strength signal intensity of the expection signal intensity ratio honeycomb 55615 of honeycomb 45615 in the simulation estimate display block.Be noted that absolute signal intensity level and uncorrelated, just be used for calculated difference.Like this, honeycomb 45615 is added in the summary document, and its signal strength signal intensity is-91dB.

If detect new honeycomb in portable terminal, this portable terminal must not have all information of the section summary document process inconsistency by upgrading it of being used for, even provisionally.If portable terminal detects potential new honeycomb, then this portable terminal can be realized one or more following options:

* make the situation of section send message to indicate the possibility of described new honeycomb for " outward " and to server.This message can be special-purpose message or the status update of having the measurement data that is associated.

* this portable terminal can be arranged to the section situation " interior ", and sends message to indicate the possibility of described new honeycomb to server.This message can be special-purpose message or the status update of having the measurement data that is associated.

* this portable terminal can add described honeycomb to its section summary document, this cellular marker is become will be left in the basket, and send message so that this action is notified to it to server.

Remove the honeycomb that uses

When honeycomb is removed when using, section summary document is adjusted to adapt to the method for optimizing that changes be to remove this honeycomb from each relates to the section summary document of this honeycomb from network.Alternatively, system can keep the section summary document parameter that is associated with the honeycomb that is disengaged use, makes that then this section can be upgraded exactly if this honeycomb is being reused in the future.

The execution mode of replacing is to the cellular application ignore-tag in all affected section summary documents.To this method disadvantageously honeycomb be disengaged use.

The another execution mode that processing is disengaged the honeycomb of use is to use the more multiple-effect fruit of wireless network simulation to determine to make honeycomb remove use.Direct affected summary document can be determined by above-mentioned observation.Further effect is to remove the place of using to have reduced this is disengaged the employed frequency of honeycomb of use and the interference level of side frequency channel.Can use simulation to observe whether to have any summary document to be updated to have because the additional honeycomb that disturbs minimizing to become and to hear in specific location.

Use ignore-tag

Ignore-tag can be used as adjustment to adapt to the method that network changes.This mark can be used automatically and be removed under the incident of server or portable terminal or the triggering of time.The Systems Operator also can use ignore-tag or ignore-tag is used as the parameter that is associated with each honeycomb in the database via administration interface.The mechanism of carrying out ignore-tag below has been discussed:

Use to ignore-tag can be controlled from location-server, and location-server sends order to ignore the one or more honeycombs on one or more summary documents to one or more portable terminals for this reason.As discussed above, server also will uncared-for honeycomb add the transmission order in the summary document to.Server is incited somebody to action the interim clauses and subclauses that issue an order is similarly removed ignore-tag and/or removed the summary document.Be under the situation of honeycomb of interim non-operational at honeycomb, detect then remove ignore-tag in case server can randomly notify the referred honeycomb of portable terminal to be moved terminal once more.

Mobile radio terminal also can be implemented ignore-tag and interfere without location-server when this wireless terminal detects some incident.The example of such incident is to handle via zone detection to detect unknown honeycomb, as described in other place of this specification.Alternatively, portable terminal can be provided with for example 10 minutes time restriction on ignore-tag, and when the hypothesis location-server will be in this time be made response to the action of portable terminal, this portable terminal can continue to use ignore-tag simply.

Section is set up new registration procedure

Can be used for adjusting a kind of method with the change that adapts to network configuration and be in case to network implementation just section is remeasured to be also referred to as during change and sets up new registration procedure.If this is particularly useful when having new honeycomb to be used.This processing cause producing new section summary document and thereby accurately compensating network change any influence to the wireless measurement of definition section.This processing sends message by the application program of system in portable terminal and plays a role, and this message makes portable terminal start a function, and this function allows user's initialization registration procedure.This can implement under optional control.Randomly, the influence which section of described system estimation can be changed, and allow in those sections each to be set up new registration procedure.Randomly, this system section set that will be allowed to set up new registration procedure influence of being constrained to wherein said change is considered to significant those sections.The definition of significant change comprises that the existence of new honeycomb and the change of expection received signal intensity surpass predetermined threshold value (such as 3dB).Randomly, any section summary document of not set up new registration procedure can be deleted by this system in the preset time window.For example, the time that the user is given a week is set up new registration procedure section after network changes, and after this week, the deleted and any related service of existing section summary document is ended till this section is set up new registration procedure.Alternatively, if the user is not benefited the chance in (for example 2 weeks) in the stipulated time, then this system removes setting up new registration procedure the permission of section.Alternatively, this system can send message so that notify their sections to set up new registration procedure permission because may influencing of zone detection performance granted to the user.Similarly, if can send text message so that notify the user to implement that option then the user must set up new registration procedure section.Alternatively, described portable terminal can the new honeycomb of notified existence and is ignored this new honeycomb.If, permit that then section is set up new registration procedure when this portable terminal stylish honeycomb in section is detected.This permission can be granted automatically by portable terminal, perhaps notifies the existence of new honeycomb and central server to grant permission and grant this permission automatically by the response portable terminal to central server.

Propagate and change

In case for section summary document calculations goes out to upgrade, the summary document after then upgrading will be sent to each system element, for example need the mobile radio terminal of that section summary document definition.No matter how character that this change can take place: no matter be change to one or more identifiers, and still to the change of one or more signal strength parameters, or to such as the change of the such Application Parameters of application program or to the removing of ignore-tag.

Make section summary document adapt to seasonal variations

In some geographic area, the seasonal variety of plant can cause the remarkable change of signal level that portable terminal is received in cellular band.In this case, system of the present invention can use the suitable correction factor with the change signal attenuation between compensation base station and the user hotline.The density of vegetation may be bigger the suburb and rural areas in may more need such correction.
