Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of control method of mobile terminal.
Background technology
UMTS(Universal Mobile Telecommunication System, universal mobile telecommunications system) be 3GPP(Third Generation Partnership Project, third generation partner program) a kind of third generation (3G) cordless communication network technical standard of tissue definition.UMTS network is made up of core net and Access Network, and core net comprises CS(Circuit Switching, circuit switching) territory and PS(Packet Switching, packet switching) territory.CS territory provides based on Circuit-switched business, as speech business; PS territory provides the business based on packet switching, as Internet access.3GPP organizational protection or formulated bis-generations of 2G(such as GSM, GPRS, EDGE) standard, and the 3G standard such as WCDMA, TD-SCDMA.The another one system CDMA2000 of 3G technology, its standard is organized to set up by another one.
LTE(Long Term Evolution, Long Term Evolution) technology is a kind of important technology of cellular communication after 3G.In the standard operation of 3GPP, LTE project is mainly for the evolution of Access Network; SAE(System ArchitectureEvolved, System Architecture Evolution network) project is mainly for the evolution of core net.LTE comprises time division duplex LTE(LTE TDD, or is called TD-LTE) and Frequency Division Duplexing (FDD) LTE(LTE FDD).
LTE and SAE emphasis have been optimized PS territory Packet Service, and have cancelled CS territory.Therefore, in LTE network, do not support traditional CS territory speech business, speech business mainly depends on the MultimediaSubsystem based on IMS(IP, IP multimedia system) VoIP(Voice Over IP, ip voice) provide.Another method is CSFB(Circuit Switched Fall Back, circuit switching fall-back).CSFB flow process can make user's CS business transfer to the access network of relatively low bandwidth, for example GSM, WCDMA, TD-SCDMA.
Due to the variation of operator and the communication network of runing, after 3G occurs, more and more mobile terminals are all multimode terminals.Support the terminal of plurality of communication schemes, for example, when supporting 2G system, also support 3G system.Support the mobile terminal of 5 patterns, support the terminal of GSM/GPRS/EDGE, WCDMA, TD-SCDMA, LTE TDD and LTE FDD, after several years, perhaps can become main flow terminal.
The corresponding network of above-mentioned these patterns is all cellular communications networks.Region is divided into community, lane place and Route Area by cellular network.There is the cell ID (Cell ID, the standard also having is referred to as Cellidentity) of oneself each community, with and affiliated Location Area Identification (LAI) and Routing Area Identifier (RAI); At this, above-mentioned mark is referred to as to cell identity information.Multimode terminal can be measured the neighbor cell of multiple patterns of network configuration, and selects suitable community, on the network of resident Dao Gai community institute associative mode.Conventionally the network of different mode is to use different PLMN(Public Land Mobile Network, public land mobile network) value differentiation.
When overlapping covering, may there is pingpang handoff in neighbor cell in mobile terminal.The signal strength signal intensity of phenomenon, especially neighbor cell that so-called pingpang handoff is exactly mobile terminal to be switched back and forth in Serving cell and neighbor cell is all in very weak situation, and terminal may repeat resident or switch between multiple communities.Pingpang handoff process easily causes speech quality unintelligible, experiences thereby affect user.
Except multimode, the another one Evolution Tendency of mobile terminal is intelligent.Intelligent mobile terminal, comprises the panel computer with communication function, has configured abundant ancillary equipment.These ancillary equipment comprise the devices such as global positioning system (GPS), bluetooth, wireless lan (wlan), FM receiver (FM), high-resolution pick-up device, large scale touch screen; And intelligent terminal is also supported to apply widely.For example, download thousands of application software by network, be then installed on smart mobile phone, as digital map navigation, Mobile banking, game etc.
The frequent meeting of WLAN and Wi-Fi lump together.It is the abbreviation of Wireless Fidelity (wireless fidelity) that Wi-Fi starts most, refers to " wireless compatibility certification " at the category of WLAN (wireless local area network).IEEE(Institute of Electrical and Electric Engineers) specification of 802.11 series is WLAN standard that IEEE organizes to set up.In 802.11 specifications, following two kinds of equipment or entity are defined.Mobile radio station (STA), any equipment that contains the wireless medium interface that meets IEEE 802.11 media access controls (MAC) and physical layer defined; Access point (AP), has the function of mobile radio station (STA), and provides any entity of access by wireless medium for associated STA.
Each access point has a service configuration identifier (SSID, i.e. service set identifier) to identify its oneself, and SSID is broadcasted in the frame of beacon frame, and at other frames, for example, in probe request frame, is cited.SSID is equivalent to the title of access point.Each access point also has a basic service that identifier (BSSID, i.e. basic serviceset identifier) is set, and BSSID is equivalent to the MAC Address of access point, conventionally appears at the somewhere in address 1 to the address 4 of MAC head.In the specification of 802.11 series, also define mobile radio station and be linked into the process of access point, access procedure comprises association process and the verification process that also may need.Different authentication modes, its authentication phase may be accompanied by the association process described in agreement; Also may be after association process described in agreement, to carry out again certification.Mobile radio station, in association with by after authenticating, just can pass through access point, the service that uses access point to provide, and for example Internet connects.
Intelligent terminal, after the success of access Wi-Fi access point, can be recorded the identifier of access point conventionally, comprises its SSID and BSSID, and the information such as authentication mode, authentication password that may need.At this, this record is referred to as to Wi-Fi Network records.
In order to save power consumption, the intelligent terminal that has accessed Wi-Fi conventionally can be in the time that screen be closed, or screen closes after a period of time, closes Wi-Fi.Need to use intelligent terminal Deng user time, when having opened screen, one surely terminal can be automatically the previously Wi-Fi network of access of access again.
From above-mentioned, more and more due to the pattern that the device that mobile terminal is supported is more and more, support, power consumption is also increasing, therefore saves the principle that must consider emphatically when power consumption is Terminal Design.

Embodiment
In embodiment, describe below detailed features of the present invention and advantage in detail, its content is enough to make any those skilled in the art understand technology contents of the present invention and implement according to this, and according to the disclosed specification of this specification, claim and accompanying drawing, those skilled in the art can understand object and the advantage that the present invention is relevant.
Illustrative to the description only actually of at least one exemplary embodiment below, never as any restriction to the present invention and application or use.
The invention provides a kind of control method of mobile terminal, for reducing the power consumption of mobile terminal, and can reduce the probability of mobile terminal pingpang handoff.
Fig. 1 illustrates according to the schematic diagram of embodiments of the invention one.Particularly, Fig. 1 shows statistics and the storage of presence information.
The control method of mobile terminal provided by the invention comprises the presence information (101) of adding up and store community.Described presence information comprises, but be not limited to, the cell identity information of the resident community of mobile terminal and following information partly or entirely: the weight of the time period of resident time span, resident accumulated time, resident date, resident number of times, the number of times of dialing or receive phone or accumulated time length, the number of times that uses packet switch domain service or accumulated time length, statistics presence information, resident probability, institute persistent district, the resident accumulated time of dividing by the period, resident probability, resident number of times, the function being associated with aforementioned information.
For example, the presence information of community is added up and stored to mode that can according to the form below.
| Cell?ID | 0xA1 | 0xA2 | 0xA3 | 0xA4 |
| Whether just resident | Be | No | No | No |
| Residing mode | GSM | GSM | LTE | GSM |
| The timing statistics cycle | 7 days | 7 days | 7 days | 7 days |
| Current/last time resident duration | 60 minutes | 5 hours | 3 hours | 1 hour |
| Accumulation residence time | 55 hours | 90 hours | 10 hours | 4 hours |
| Accumulate resident number of times | 80 times | 100 times | 5 times | 3 times |
| Circuit domain business duration | 100 minutes | 50 minutes | 15 minutes | 0 minute |
| Packet switch domain service duration | 40 minutes | 30 minutes | 30 minutes | 5 minutes |
| Accumulate resident probability | 0.35 | 0.56 | 0.06 | 0.03 |
| In the daytime resident accumulation duration of period | 40 | 30 | 5 | 4 |
| The resident accumulation duration of night-time hours | 15 | 60 | 5 | 0 |
| In the daytime resident probability of period | 0.51 | 0.38 | 0.06 | 0.05 |
| The resident probability of night-time hours | 0.19 | 0.75 | 0.06 | 0 |
Can there be multiple dividing mode the above-mentioned middle period, and for example each hour as a period, or simply will within one day, be divided in the daytime and two periods of night, and in the daytime from 6:00 to 18:00, night is from 18:00 to 6:00.Resident probability, or by the resident probability of period, can add up the accumulation of each community or simply by the resident duration proportion of period; Also can, by above-mentioned all parameters, comprise each duration, number of times etc., each parameter weighting, calculates a comprehensive probability.For example, number of times and duration weight are all 0.5, calculate the weight of the resident number of times in each community and duration, then average, and calculate last probability.Probability in upper table, has used the method for resident duration proportion to calculate.
The weight that resident probability directly can be considered as to institute persistent district, also can mark off multiple ranks by span by resident probability, the corresponding weight of each rank.For example, probability was at 0 to 0.25 o'clock, and weight is 1; Probability was at 0.26 to 0.5 o'clock, and weight is 2; By that analogy.
In above-mentioned example, provide the presence information statistics of 7 days; The accumulation residence time deficiency of Si Ge community 168 hours.The remaining time, can be understood as mobile terminal in off-mode.
An above-mentioned just example, actual related number of cells should be more.
For the presence information that continuous updating is stored, can use following method.Each resident Dao Yige community, for example 0xA1 community, records the initial time of its cell identity information, pattern or PLMN, resident Dao Gai community.Resident to other communities when leaving 0xA1 community, or when shutdown, according to current time, calculate the resident time span to 0xA1 community, and record corresponding period and date.
If the time cycle of statistics is 7 days, there will be the sequence being formed by many records, each record is comprising cell identity information, pattern, resident period, resident date, resident duration.
Like this, each hour, or before each shutdown, or after each start, mobile terminal is added up once above-mentioned records series, by cell identity information, add up the information such as duration, number of times, probability of resident Dao Gai community, and further upgrade the presence information of storing.
In the time having there is the cell identity information of not stored before, corresponding this cell identity information presence information is stored.When certain cell identity information of storing before, while appearance, delete the corresponding presence information of this cell identity information in the records series of nearest 7 days.
The method of above-mentioned records series is a kind of the simplest method just.The method of statistics presence information can have multiple.For example, set up the list of identification information of all resident Guo community, every passing hour, just corresponding each community residence time is multiplied by 167/168, then this hour corresponding resident duration in resident community added to 1/168.Such mode, can make resident probability Hen little community, and the resident duration of its correspondence is more and more less, until level off to 0.
The presence information of above-mentioned statistics, can store in the Flash of terminal inner, or inserts in the SIM card or SD card of terminal.
Above-mentioned statistics and stored the parameter such as duration, number of times, the further function of statistics and storage duration, number of times, probability etc.For example, distinguish the function of conventional community,, in the time that resident probability is greater than 0.3, functional value is 1; Otherwise be 0.Mobile terminal can be got according to the function of conventional community, judges whether current area is often resident community.
According to the present embodiment, can make termination environment which separate in resident community is conventional community, and can make terminal further according to these information, terminal be controlled.
Fig. 2 illustrates according to the schematic diagram of embodiments of the invention two.
Embodiment bis-provides a kind of method of controlling mobile terminal, and the method comprises the presence information (201) of storing and add up community; And according to the presence information storing and add up control mobile terminal (203).
Because presence information has in fact comprised user's positional information and motion track, therefore, can control cell measurement or the model selection that mobile terminal carries out according to presence information, save power consumption and improve the object that user experiences thereby realize.
The selection of described terminal to pattern, refers to that terminal is resident a certain public land mobile network, in the pattern of supporting, selects applicable pattern, and work in this pattern in terminal.Every kind of pattern that terminal is supported is corresponding a kind of wireless access technology (RAT) conventionally.And operator is in the time of Operation Network, different RAT uses different PLMN numberings conventionally, multiple PLMN that certainly also do not got rid of identical RAT correspondence, or identical PLMN correspondence the situation of multiple RAT.In any case but terminal all can be selected an applicable pattern, and work in this pattern, to can realize normally resident to selected PLMN.At this, by resident terminal during to a PLMN, selected, use or the pattern of work, also referred to as the resident pattern of terminal.
For example, from the table shown in embodiment mono-, can judge user's positional information.0xA1 community should be the community that user job unit is positioned at, and 0xA2 should be the community that user dwelling is positioned at, and 0xA3 is likely the user community that is positioned at of handling affairs of going out, and 0xA4 is the community that user passes by temporarily.
From user's motion track, especially for the obvious user of the rule of life towards nine evenings five, be usually located at place work unit its workaday daytime; The daytime at weekend and all nights, very large probability is positioned at dwelling.Therefore,, from the resident probability of mobile terminal, period daytime on working day, residing in community that work unit is positioned at is Great possibility; Residing in community, place, dwelling at night and weekend is Great possibility.
In mobile terminal, in most time, reside in a certain specific community.Only during user moves, for example, go to work, in next way, just occur roaming and switch.In the time that mobile terminal resides in a certain specific cell, the neighbor cell of this community, can will obviously be less than in fact for the number of cells of terminal gravity treatment and switching the number of whole neighbor cells that network configures.That is to say, the probability that mobile terminal is static is greater than the probability of motion; In the time of motion of mobile terminals, the probability moving in a specific cell is greater than the probability in minizone motion.
In the present embodiment, mobile terminal is the measurement to community according to presence information control, comprises and increases and/or reduce the measurement to community; And the selection of the resident PLMN/ pattern of control mobile status.
In one embodiment, mobile terminal is set presence information threshold value.The threshold value of presence information, can arrange according to duration, number of times, probability philosophy, also can be only according to probability or weight setting.When the duration of resident certain community, number of times, probability, weight etc., while exceeding the presence information threshold value setting, reduce the measurement to community.The threshold value of presence information can also be the number of conventional community.For example be set to 2.In all resident communities, resident maximum probability Liang Ge community, resident during to this 2 communities when mobile terminal, reduce the measurement to community.Referring to embodiment mono-, when the community of resident maximum probability is 0xA2,0xA1,, in the time of the resident Dao Zheliangge of mobile terminal community, reduce the measurement to community.
For example, the threshold value that by the resident duration of accumulation the presence information of presence information is set is 50 hours., from the chart of embodiment mono-, the resident duration of community 0xA1 and community 0xA2 exceedes this threshold value., in the time of the resident Dao Gai of terminal community, reduce the measurement to community, especially reduce neighbor cell, or the measurement of the neighbor cell of other patterns.
And for example, the threshold value that by the resident probability of the accumulation of period presence information is set is 0.3.From embodiment mono-, the period in the daytime, the resident probability of community 0xA1 and community 0xA2 exceedes 0.3; The resident probability of night-time hours community 0xA2 exceedes 0.3.In the daytime, resident during to community 0xA1,0xA2 when terminal, reduce the measurement to community; At night, in the time that terminal resides in community 0xA2, reduce the measurement to community.
Above-mentioned resident to reducing the measurement to community behind certain community, the community of measurement comprises the neighbor cell under neighbor cell under this community and the resident PLMN of institute and other PLMN.But conventionally reduce or stop measure, be the neighbor cell under other PLMN.Be placed in the less amplitude in neighbor cell under this PLMN, should be less than the measurement to the neighbor cell under other PLMN.The frequent degree of measurement of Dui Zhe community, is recommended as and does not reduce.
Network can, to the multiple neighbor cells of terminal configuration, for multimode terminal, also can configure the neighbor cell of multiple other patterns.And mobile terminal should, taking the cycle as unit, be measured configured neighbor cell and resident community.
The community that terminal is resident, is current service cell, other Ze Wei neighbor cell, community.Neighbor cell can be divided into again (Inter-RAT) adjacent area between interior (Intra-RAT) adjacent area of system and system.Adjacent area in system, refers to the current resident PLMN network Nei community of mobile terminal, more precisely, is the community that uses current wireless access technology (RAT); Adjacent area between system, refers to the neighbor cell outside current PLMN or current wireless access technology.For example, if terminal works in GSM pattern, the neighbor cell of GSM network is adjacent area in system, the neighbor cell of TD-SCDMA, LTE network is exactly adjacent area between system; If terminal works is in LTE pattern, the adjacent area of LTE network becomes adjacent area in system.
To the measurement of neighbor cell comprise comprise in system measure and/or system between measure, between system, measure and be also referred to as cross-system and measure.Above-mentioned to the measurement of other PLMN/ mode networks outside resident PLMN/ pattern, be cross-system and measure.
For example, in 1.28 seconds, mobile reply all monitoring Ji community completes measurement once; And as far as is humanly possible other communities outside monitoring collection are measured with polling mode.The title difference of monitoring collection in various patterns, generally, refers to that mobile terminal is in the time of cell reselection, switching or soft handover, the set of most probable Target cell.And community outside monitoring collection, normally network configuration but community that in fact terminal can't detect or measured but the very weak community of signal, then or network does not configure but mobile terminal detects Liao community.Also the communication system having, the concept of indefinite regulation monitoring collection, but require terminal by signal strength signal intensity, to be sorted in the community measuring, and it is several above, for example 8 communities, require to measure once described cycle planted agent, and the measurement of other communities is requirement in power.This number that has been equivalent to specify monitoring collection is in 8.
The mode of the measurement of described minimizing to community, comprises increasing measuring period, reduce the number of times of measuring community in each measuring period, reducing the number of the community of measuring in each measuring period and/or insert the cycle of not measuring between measuring period.
For example, network configuration requires 1.28 seconds to measure the community that once configured, and now terminal can 2.56 seconds or the community that once configured of longer period measurement.In addition, for multimode terminal, for example GSM/TD-SCDMA/LTE TDD tri-mould lists are treated terminal, if the current GSM community that resides at of mobile terminal can stop the measurement of the community to other patterns.Also can be by not reducing measuring period, the method that still reduces the number of cells of measuring in one-period reduces the measurement to community.Or still measure according to the frequent degree of measurement in the cycle of existing configuration and each cycle, but between measuring period, insert the time period that stops measurement.
The measurement of above-mentioned minimizing to community, following operate part or all of of simultaneous:
Reduce or stop mobile terminal to the measurement of other PLMN/ mode networks outside resident PLMN/ pattern; When cell reselection, do not select the community of other PLMN/ patterns outside resident PLMN/ pattern carry out resident; Select other patterns outside LTE pattern resident; Improve the thresholding that mobile terminal carries out cell reselection.
Can reduce or stop measurement, gravity treatment to other mode cell, and not reduce this pattern, the measurement of resident PLMN Xia community, can ensure like this connectedness of mobile terminal under situation of movement.Like this, do not added up and stored Guo community once mobile terminal is resident to its presence information, or resident probability Hen Di community, recover the desired measurement to community of prior art, comprise the measurement and the gravity treatment that recover other mode cell.
The operation that above-mentioned minimizing is measured, can reduce while starting to community resident, starts minimizing after also can continuing for some time behind resident Dao Gai community.Latter event is optimized more.Due to just, from resident Dao Gai community, other communities, signal quality is also unstable, therefore needs a period of time stably to measure neighbor cell.For example, resident Dao Gai community, continues, after 10 minutes, whether to belong to resident probability at first 2 according to this community, determines whether reducing and measures.
In addition, whether reduce measurement, can be according to the presence information of stored statistics, also can be according to current just at the presence information of resident community.
For example, the current period is night, and current area is resident 4 hours, and current time is 2 o'clock mornings, can judge that user is probably between sleep period; The probability of fast mobile terminal is very little.Even if this community is Yi Gexin community, do not added up and stored, also can carry out and reduce the operation of measuring.
The advantage of the present embodiment is, reduces and measures, and saves the power consumption of terminal; Reduce and measure in resident probability great community, especially only reduce the measurement to other pattern adjacent areas, make terminal reduce power consumption under large Probability Condition, and do not reduce the connectivity of terminal and cellular network.
Above-mentioned minimizing is measured, be with respect to communication protocol defined in prior art for the measurement task in the system of Serving cell, neighbor cell or outside system, measuring period.In the prior art, network can configure paging cycle, and for example 640 milliseconds or 1.28 seconds, this cycle is conventionally also as using measuring period; In the communication protocol of some system, directly specify a measuring period, or the report cycle of measurement result.Network simultaneously can be in terminal configuration system and system outside the parameter of neighbor cell, the synchronous code that comprise neighbor cell frequency used, cell ID, uses etc., the design parameter comprising in the neighbor cell list of each system is different.In communication protocol, also specify, in middle measuring period, the measurement to measuring amount that terminal should complete, as completed the measurement of at least 1 time to how many communities.
Therefore, in the prior art, mobile terminal is taking the cycle as unit, and the measurement target and the requirement that at least configure by the desired frequent degree of agreement and network, measure configured neighbor cell and resident community.Reduce or increase and measure, refer to minimizing or increase with respect to the measurement task in the some cycles of prior art communication protocol defined.Suppose network configuration Liao20Ge community, in measuring period or measurement report cycle, should at least measure each community 1 time, can be understood as so current period measurement number of times is 20.In same period, average measurement number of times is less than 20 so, can be understood as to reduce to measure, and unnecessary 20 can be understood as increase measurement.
Fig. 3 illustrates according to the schematic diagram of embodiments of the invention three.
Embodiment tri-is with the difference of embodiment bis-, on the basis of embodiment bis-, further adds and increases or the operation (305) of recovery to cell measurement.
In embodiment bis-, reduce or stop the measurement to other mode cell, be unfavorable for that terminal is resident to the best PLMN of signal quality.Therefore, can set very first time threshold value and the second time threshold, for example, be set to respectively 10 minutes and 1 minute.Exceed very first time threshold value whenever the duration that reduces measurement, measurement is returned to the degree before reducing, and maintain the second time threshold, 1 minute.
The advantage of the present embodiment is, reducing under the prerequisite of power consumption of terminal, still makes the terminal can be resident on applicable pattern.
The present invention also provides embodiment tetra-.
The difference of embodiment tetra-and embodiment bis-and three is the control to reducing measurement degree.
To the minimizing degree of cell measurement, can be change with changeless two kinds, or both combinations.
Changeless mode, with respect to the frequent degree of measuring being divided into normal and two kinds of reducing.For example, be 1.28 seconds the measuring period of current network configuration, and reduce while measurement, and be 2.56 seconds measuring period., be positioned at resident probability once mobile terminal and be greater than 0.3 community, reduce the measurement to community; Otherwise, by the frequent degree measurement of normal measurement.
The mode changing, operable method is a lot.
For example, by resident probability, divide multiple ranks, each rank is measured the degree difference reducing.As resident probability is greater than 0.5 community, stop the measurement to other pattern adjacent areas; Resident probability is in the community of 0.3-0.5, to being the measuring period of other mode cell 2.56 seconds.
And for example, directly use resident probability calculation measuring period.As, measuring period being (the resident probability of 1+) × 1.28 seconds.After this resident probability Yue little community, reside at, and measuring period is shorter.
It is pointed out that and it will be understood by a person skilled in the art that the present invention is not limited to the above-mentioned embodiment enumerating.And the embodiment that the present invention enumerates all can combine mutually and apply, further to optimize technical scheme of the present invention.
