Abstract
The method comprises: when the controllers of base stations are in a separation state, the destination base station controller sends the region- classified ID of current cell that user device affiliates with to the source base station controller through the interface between the base station controllers; based on the region-classified ID of the user device carried by the interface message, the source base station controller makes location decision for the classified region to decide if the user has left or entered the classified region; if yes, then the source base station controller reports the location decision result of the classified region of the user device to the core network through a location report message.
Description
Technical field
The present invention relates to the mobile communication system location technology, refer to the method for locating classified regions under a kind of base station controller released state especially.
Background technology
The location-based service business is admitted by operator and user the value of subscriber equipment location as one of characteristic value-added service of wireless communication system.At present, the location-based service business is used widely at aspects such as traffic monitoring, automobile navigation, urgent rescues, and plays an important role.
Location technology based on cell ID (CellID) is a most basic a kind of localization method in the location-based service business, and this method is applicable to all cellular networks.Positioning principle based on CellID is: the position and the sub-district of the current serving BS of living in of network based subscriber equipment cover positioning mobile station.
Especially, when some zone is in particular surroundings, such as infectious disease takes place, need monitor entering or leave these regional subscriber equipmenies, these special areas are called as specification area.For can supervisory user equipment the situation of turnover specification area, provide the function of configuration specification area at the operating desk of base station controller, mark is set promptly for different specification areas.A specification area is mapped as one or more coverages (SA), the zone that SA is made up of the one or more sub-districts that belong to a certain co-located region (LA).
According to 3G (Third Generation) Moblie partner program (3GPP) standard TS 25.413 regulations, when subscriber equipment enters or leaves a specification area, radio network controller (RNC) at first triggers the judgement of specification area location, then, universal mobile telecommunications system land radio access web (UTRAN) sends a position message (LOCATION REPORT) message to core net (CN), the Service Area Identifier (SAI) and cause value (CAUSE) cell that comprise the affiliated service area of this subscriber equipment in the message, here, SAI is used for the zone that unique identification is made up of the one or more sub-districts that belong to a certain identical LA, this zone is used to indicate the position of subscriber equipment in the band of position, the coverage of representing the subscriber equipment place with SAI, the CAUSE cell then should indicate user's restriction and begin indication (UserRestriction Start Indication), and the expression subscriber equipment enters the specification area corresponding with this SAI; Perhaps the user limits and finishes indication (User Restriction End Indication), and the expression subscriber equipment leaves the specification area corresponding with this SAI.After CN received position message, then the strategy according to operator's regulation carried out respective handling to this position message.The method of above-mentioned specification area location judgement is: corresponding with specification area if the SAI of the current affiliated subdistrict of subscriber equipment is set to, then adjudicating the current affiliated subdistrict of subscriber equipment is specification area; If it is not corresponding with specification area that the SAI of the current affiliated subdistrict of subscriber equipment is set up, then adjudicating the current affiliated subdistrict of subscriber equipment is not specification area.
When the unfiled zone of judgement subscriber equipment current affiliated subdistrict, RNC is carried at the SAI of the current affiliated subdistrict of subscriber equipment and cause value " User Restriction Start Indication " and reports core net in the position message; When the current affiliated subdistrict of judgement subscriber equipment was not specification area, the SAI of affiliated subdistrict and cause value " User Restriction EndIndication " were carried at and report core net in the position message before RNC switched subscriber equipment.
At present, fairly simple to the method for specification area location, mainly judge according to configuration information and realize by base station controller.Be example with Wideband Code Division Multiple Access (WCDMA) (WCDMA) system below, be described in detail.Fig. 1 is the UTRAN structural representation of prior art based on the WCDMA system, and sub-district 1 and sub-district 2 belong in the RNC1 scope, and sub-district 3 belongs in the RNC2 scope.Suppose that sub-district 1 is set to specification area among Fig. 1, and the label of SA is SAI1 under the sub-district 1; Sub-district 2 is not a specification area, and the label of SA is SAI2 under the sub-district 2; Sub-district 3 is specification areas, and the label of SA is SAI3 under the sub-district 3.
For specification area is positioned, at first, need each RNC to dispose the interior specification area information of scope separately respectively, promptly dispose some SA and belong to a specification area, and some SA belongs to another specification area according to demand.Like this, when RNC obtains SAI information, can judge just whether the SA of SAI correspondence belongs to specification area, and belong to which specification area.Suppose to have disposed among the RNC1 above-mentioned SAI1 and belong to specification area I, SAI2 does not belong to any specification area; Dispose SAI3 among the RNC2 and belonged to specification area II.
After UE inserts sub-district 1, stipulate according to agreement, RNC1 triggers the judgement of specification area location, SAI1 according to SA under the sub-district 1, RNC1 judges that sub-district 1 is a specification area, and this moment, UE inserted sub-district 1, so RNC1 reports position message message to CN, the SAI1 that in the reporting message of position, comprises the SA under the sub-district 1, and cause value User Restriction Start Indication.
When UE 1 switches to sub-district 2 from the sub-district, and after finishing switching flow, RNC1 triggers the specification area location determination, according to the SAI2 of SA under the sub-district 2, RNC1 judges that sub-district 2 is not a specification area, and this moment, UE left sub-district 1, enter sub-district 2, so RNC1 reports position message message to CN, comprise the SAI1 of the SA under the sub-district 1 in the position message message of this moment, and cause value UserRestriction End Indication.
As can be seen from Figure 1, affiliated scope of RNC1 and the affiliated scope of RNC2 are all crossed in sub-district 2 and sub-district 3, method according to prior art specification area location, need RNC1 that sub-district 3 is configured, promptly in RNC1, dispose the specification area information that SAI3 belongs to specification area II, simultaneously, also need RNC2 that sub-district 2 is configured, promptly in RNC2, dispose the specification area information that SAI3 belongs to specification area II.Only in this way, when UE from the sub-district 2 when switching to sub-district 3, RNC1 just can know the current specification area that whether is in of UE.
When UE 2 switches to sub-district 3 from the sub-district, in switching flow, RNC2 is in the message of RNC1 response when setting up Radio Link, the relevant configuration information of the sub-district 3 that UE can be switched to sends to RNC1, RNC1 is then according to the SAI3 of SA under the sub-district in the relevant information of sub-district 33, the SA that searches the local SAI3 correspondence that has disposed belongs to the specification area information of specification area II, judge that UE enters specification area II at this moment, RNC1 reports position message message to CN, the SAI3 that comprises the SA under the sub-district 3 in the position message message of this moment, and cause value User Restriction StartIndication.
Switch to from sub-district 2 under the situation of sub-district 3 at above-mentioned UE, RNC1 is the Serving RNC (SRNC) of UE, and the Radio Resource basic function of UE is managed; And the RNC2 that UE switches under the sub-district 3 are control RNC (CRNC), are responsible for the Radio Resource of the sub-district of its control is managed, and after UE switched to RNC2, RNC2 also was the Drift Radio Network Controller (DRNC) of UE simultaneously, and the link establishment of UE this moment is on DRNC.With this SRNC and DRNC or CRNC is not that the situation of same RNC is called base station controller and separates.
2 situations that switch to sub-district 3 are as seen from the sub-district for the UE that describes from above-mentioned Fig. 1, under the base station controller released state, RNC will be referred to the relevant information allocation problem of peripheral adjacent R NC to the configuration effort of specification area, and the affiliated sub-district of RNC may be thousands of, and a RNC can have a plurality of adjacent RNC, so, in the prior art, dispose the specification area information of peripheral adjacent R NC affiliated subdistrict at a RNC, be a job of wasting time and energy, along with the dilatation of network, this method is unpractical.
Be that example is introduced with the WCDMA system more than, described base station controller separates and is meant between SRNC and CRNC or the DRNC and separates that also SRNC can be called source RNC, CRNC/DRNC is called purpose RNC.In addition, such as in gsm system, base stations control is separated and then to be referred to separate between source base station controller (BSC) and control BSC or the purpose BSC.

Embodiment
Core concept of the present invention is: under the base station controller released state, the purpose base station controller sends the specification area sign of the current affiliated subdistrict of subscriber equipment to the source base station controller by the interface message between base station controller; The source base station controller is according to the specification area sign of this subscriber equipment that carries in the interface message, carry out the judgement of specification area location, determine whether subscriber equipment leaves or enter specification area, if subscriber equipment enters or left specification area, then the source base station controller reports the specification area location court verdict of this subscriber equipment to core net by position message message.
Fig. 2 is a method for locating classified regions flow chart of the present invention, in the subscriber equipment cross base station controller switches, under the base station controller generation released state, may further comprise the steps:
Step 200: subscriber equipment place purpose base station controller identifies the specification area of the current affiliated subdistrict of subscriber equipment in the interface message that is carried between base station controller, sends to the affiliated source base station controller of subscriber equipment.
For base station controller, which sub-district in its coverage is a specification area, has been provided with when configuration, in the base station controller configuration, increases specification area sign for each sub-district among the present invention, is used to represent whether this sub-district is specification area.Such as, specification area is designated 1 expression effectively, and promptly this sub-district is a specification area, and it is invalid that specification area is designated 0 expression, and promptly this sub-district is not a specification area.
In this step, when subscriber equipment switched between different base station controller affiliated area, the present invention was carried at the specification area sign of the current affiliated subdistrict of subscriber equipment in the interface message that has now between base station controller, returns to the source base station controller.Here, the interface message between base station controller can be that the Radio Link in switching is set up response message etc., promptly utilizes the Radio Link that has now in the switching flow to set up response message and transmits the specification area sign.
Step 201: the affiliated source base station controller of subscriber equipment carries out the judgement of specification area location according to the specification area sign of carrying in the interface message between the base station controller that receives, and reports court verdict to core net transmission position message.
The concrete processing and the prior art of this step are in full accord, and just the source base station controller obtains the mode difference of the specification area information of the current affiliated subdistrict of subscriber equipment:
Prior art needs to dispose in the source base station controller relevant information of this sub-district in the purpose base station controller, by the related news of source base station controller according to response, set up sub-district relevant information under the subscriber equipment that response message carries in such as Radio Link, whether the SAI that searches this pre-configured sub-district correspondence in this locality belongs to certain specification area, and whether what obtain the current affiliated subdistrict of subscriber equipment is specification area;
In the inventive method, the specification area sign that the source base station controller can be directly set up the current affiliated subdistrict of subscriber equipment that carries the response message from Radio Link directly judges whether this sub-district is specification area, if, then the SAI information of the current affiliated subdistrict of subscriber equipment and cause value User Restriction StartIndication are carried at and send to core net in the position message, the expression subscriber equipment enters the specification area of SAI correspondence; If the current affiliated subdistrict of subscriber equipment is not a specification area, then the SAI information of the sub-district that subscriber equipment is left and cause value User Restriction End Indication are carried at and send to core net in the position message, and the expression subscriber equipment leaves the specification area of SAI correspondence.
As seen above-mentioned, method of the present invention does not need the relevant information of this sub-district in the pre-configured purpose base station controller of source base station controller and the corresponding relation between the specification area, has significantly reduced workload.And along with the dilatation of network, the inventive method more can embody its practicality easily.
From above-mentioned Fig. 2 flow process as can be seen, the inventive method is to utilize subscriber equipment interface message between base station controller in the switching flow between different base station controller affiliated area, sends the specification area sign of the current affiliated subdistrict of subscriber equipment to the source base station controller by this interface message by the purpose base station controller.The source base station controller can utilize the specification area sign of this subscriber equipment that carries in this message quickly and easily like this, carries out the judgement of specification area location, determines the situation of the current discrepancy specification area of subscriber equipment.
For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing preferred embodiment that develops simultaneously, the present invention is described in more detail.
Be example with the WCDMA system below, the method for locating classified regions of different switching states is described in detail.Fig. 3 is an embodiment of the invention system configuration schematic diagram, supposes that sub-district 1 (Cell1) is set to specification area among Fig. 3, and the specification area sign of sub-district 1 is configured to 1, and the label of SA is SAI1 under the sub-district 1; Sub-district 2 (Cell2) is not a specification area, and the specification area sign of sub-district 2 is configured to 0, and the label of the SA under the sub-district 2 is SAI2; Sub-district 1 belongs in the RNC1 scope, and sub-district 2 belongs in the RNC2 scope.
In system shown in Figure 3, suppose that UE at first connects by radio resource control layer (RRC) to be based upon sub-district 1, promptly RNC1 is the SRNC of UE, and UE 1 switches to sub-district 2 from the sub-district then, and promptly RNC2 is DRNC.
When UE inserted sub-district 1, RNC reported position message message to give CN, carries the SAI1 information of sub-district 1 affiliated SA in the position message message, and cause value " User Restriction StartIndication ", illustrated that this moment, UE entered specification area; When UE switches to sub-district 2, DRNC utilizes and has the message that responds to SRNC when setting up Radio Link now, send the specification area sign of sub-district 2 to SRNC, SRNC judges that according to the specification area sign that receives the current affiliated subdistrict 2 of UE is not a specification area, judge that promptly UE has left specification area, give CN by the position message information reporting, carry the SAI information under the sub-district 2 in the position message message, and cause value " User RestrictionEnd Indication ".
Above-mentioned switching can be divided into forward direction according to actual conditions and switch with back to switching two kinds, the existing switching flow of two kinds of situations is different, for the inventive method, the message that is used to carry specification area information also can be different, be example with the WCDMA system below, respectively the forward direction switching being taken place UE is embodiment with the back to switching two kinds of situations, and the inventive method is specifically described.
Embodiment one: the method for classification zone location during cell update during forward direction switches.
Fig. 4 is the embodiment of the invention one specification area positioning flow figure, and present embodiment with UE forward direction takes place and switches to example.Forward direction switches and to be meant and to be in common signal channel, and the cell update or the Acceditation Area (URA) of initiating as the UE of sub-district FACH (CELL_FACH) state, sub-district PCH (CELL_PCH) state or Acceditation Area PCH (URA_PCH) state upgrade.
Be that example is described with the cell update among Fig. 4, in conjunction with Fig. 3, the UE that supposes to be in common channel state 1 switches to sub-district 2 from the sub-district, and RNC1 is SRNC, and RNC2 is DRNC, and this moment, the sub-district gravity treatment took place, and concrete steps are as follows:
Step 400:UE sends cell update (CELL_UPDATE) message and gives DRNC, and DRNC is according to SRNC relevant information under the UE that carries in the cell update message, and the SRNC that learns UE is RNC1.
Step 401:DRNC is by the Iur interface between RNC1 and the RNC2, the specification area sign of the current affiliated subdistrict 2 of the UE that has disposed is carried in up signaling transmission indication (UplinkSingnalling Transfer Indication) message, and this message is sent to the affiliated SRNC of UE.
In this step, it is existing message that up signaling transmits Indication message, and this message has comprised cell update message, and the configuration information of the sub-district 2 that switches to of UE, comprising the SAI2 of SA under the sub-district 2.Unlike the prior art be, transmit in Indication message in this up signaling, also carried the specification area sign of the current affiliated subdistrict 2 of UE.
Step 402:SRNC identifies according to the specification area that the up signaling that receives transmits the current affiliated subdistrict of UE that carries in the Indication message, carries out the specification area location and adjudicates and court verdict is carried in the position message.
In this step, whether the specification area sign that judgement receives is effective, if effectively, then adjudicating the current affiliated subdistrict of UE is specification area, SRNC is carried at the SAI and the cause value " User Restriction Start Indication " of the current affiliated subdistrict of UE in the position message; Otherwise the current affiliated subdistrict of judgement UE is not a specification area, and the SAI and the cause value " UserRestriction End Indication " of affiliated subdistrict were carried in the position message before SRNC switched UE.
In this step, in conjunction with Fig. 3, specification area according to sub-district 2 is designated 0, expression sub-district 2 is not a specification area, thereby judge that it is not specification area that UE works as the sub-district that advances into, also be that UE leaves specification area, the SAI1 and the cause value " User Restriction End Indication " of sub-district 1 is carried in the position message.
Step 403:SRNC will carry the SAI1 of sub-district 1, and cause value " User RestrictionEnd Indication " reports to CN in position message.
This step specific implementation and prior art are in full accord, no longer repeat here.
From above-mentioned flow process as can be seen, what the present invention emphasized is, in step 401 and step 402, because DRNC has sent to SRNC with the specification area sign of the current affiliated subdistrict of UE, like this, SRNC just need not in the relevant information of the specification area of this locality configuration adjacent R NC, saved the configuration effort of wasting time and energy, only need just can solve simply under the base station controller released state, to the problem of specification area location according to the specification area sign that receives.
Fig. 4 is that example is described with the cell update, upgrades for URA, only needs that the cell update message in the switching flow is changed to the URA updating message and gets final product.
Specifically describe behind the UE when switching for an embodiment below, the present invention carries out fixed method to specification area:
Embodiment two: the method for specification area location in switching, back.
Fig. 5 is the embodiment of the invention two specification area positioning flow figure, and present embodiment the back takes place to switching to example with UE.The back is meant handoff procedure between soft handover, direct-cut operation or the system that network side initiates the UE that is in cell private channel (CELL_DCH) state to switching.
Among Fig. 5 existing back is simplified to switching flow, emphasis is described content related to the present invention, can be with reference to 3GPP 25.931 agreements to switching flow for the back of cross-Iur interface.In conjunction with Fig. 3, the UE that supposes to be in the CELL_DCH state 1 moves to sub-district 2 from the sub-district, and RNC1 is SRNC, and RNC2 is DRNC, and concrete steps are as follows:
Step 500:UE reporting subdistrict measurement report is given SRNC, and the cell signal quality that SRNC reports according to UE is selected the measured sub-district of matter and triggered the process that cross-Iur interface switches to the measured sub-district of this matter.
In this step,, then in the measurement report that UE carries out message, be bound to show that the quality of sub-district 2 is better than the quality of sub-district 2, so SRNC can trigger the process of switching to sub-district 2 because UE 1 moves to mobile cell 2 from the sub-district.This step belongs to prior art, and the specific implementation process no longer repeats, can be with reference to 3GPP 25.931 agreements.
Step 501:SRNC sends Radio Link to DRNC and sets up request message, require to set up UE in the sub-district 2 Radio Link.
This step specific implementation process can no longer repeat here with reference to 3GPP 25.931 agreements.
Step 502:DRNC sets up UE behind the Radio Link of sub-district 2, and DRNC is carried at Radio Link with the specification area of the current affiliated subdistrict 2 of UE sign and sets up in the response message, returns SRNC.
In this step, it is existing message that Radio Link is set up response message, and this message has comprised the configuration information of the sub-district 2 that UE switches to etc., comprising the SAI2 of sub-district 2.Unlike the prior art be, set up in the response message at this Radio Link, also carried the specification area sign of the current affiliated subdistrict 2 of UE.
Step 503: 1 cross-Iur interface to sub-district 2 switches from the sub-district to finish UE.
This step specific implementation process can no longer repeat here with reference to 3GPP 25.931 agreements.
The specification area that step 504:SRNC sets up the current affiliated subdistrict of UE that carries in the response message according to the Radio Link that receives identifies, and carries out the specification area location and adjudicates and court verdict is carried in the position message.
In this step, in conjunction with Fig. 3, specification area according to sub-district 2 is designated 0, expression sub-district 2 is not a specification area, thereby judge that it is not specification area that UE works as the sub-district that advances into, also be that UE leaves specification area, the SAI1 and the cause value " U8er Restriction End Indication " of sub-district 1 is carried in the position message.
Step 505:SRNC will carry the SAI1 of sub-district 1, and cause value " User RestrictionEnd Indication " reports to CN in position message.
This step specific implementation and prior art are in full accord, no longer repeat here.
In addition, if UE has set up Radio Link at DRNC, afterwards, when UE switched between the DRNC affiliated subdistrict again, the specification area of the sub-district that UE can be switched to sign was carried in the existing Radio Link increase response message and sends SRNC to.
From above-mentioned flow process as can be seen, what the present invention emphasized is, in step 501 and step 502, because DRNC has sent to SRNC with the specification area sign of the current affiliated subdistrict of UE, like this, SRNC just need not in the relevant information of the specification area of this locality configuration adjacent R NC, saved the configuration effort of wasting time and energy, only need just can solve simply under the base station controller released state, to the problem of specification area location according to the specification area sign that receives.
The present invention is equally applicable to gsm system, GSM strengthens wireless access network (GERAN) system etc.In gsm system, base stations control is separated and then to be referred to separate between source BSC and control BSC or the purpose BSC.
In the GERAN system, the system that the RNC of WCDMA system links to each other with the BSC of GSM by the Iurg interface, the specification area that can use the present invention to solve under RNC and the BSC separation case is equally located, and is RNC such as the source base station controller, and the purpose base station controller is BSC; Perhaps the source base station controller is BSC, and the purpose base station controller is RNC.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
