Description
Technical field
The present invention relates to a kind of wireless terminal technology, relate in particular to a kind of double-mode and double-standby terminal control method, device and terminal.
Background technology
Along with the development of wireless communication technology, cellular radio access network has experienced from simulation 1G, digital 2G, broadband 3G, the more technology evolution of the LTE system of high bandwidth; Yet, in order to maximize investment return, meet customer service continuity, extend the useful life of user terminal, operator can dispose a plurality of Radio Access Networks simultaneously.If current many operations commercial city is that 2G, 3G system are being runed simultaneously, will be that LTE, 3G, 2G run simultaneously future.But, because the network design investment of operator is all to expand gradually deployment scope from point to face, so the overlay area of on-premise network is greater than the overlay area of follow-up evolution technology the earliest.Meanwhile, the evolution due to mobile communication system is driven by the broadband demand of people's business again, so business demand difference also will be brought the difference of network's coverage area.For example, in China, take and provide basic voice service to be greater than 3G system as the overlay area of main 2G system GSM, and provide future the covering of the LTE of high speed data transfer will within a very long time, be less than the covering of 2G/3G.
So a plurality of network coexisted, one side there will be the situation of each network coverage zones of different, there will be on the other hand each network implementation different business to carry tactful situation.Therefore, under the situation of simultaneously runing at a plurality of networks, how according to the coverage of network and service bearer strategy, effectively to utilize each Internet resources, for user provides continuously voice, data service reliably, become the problem that mobile communication industry has challenge very much.Wherein, because speech business is very high to real-time, continuity requirement, the main source of profits of You Shi operator, so how to realize voice business continuity in LTE and 2G/3G coexistence of systems situation, becomes the content that current industry is the most paid close attention to simultaneously.
The voice continuity problem coexisting in situation in order to solve many nets, at present industrial circle has proposed many schemes, comprises CS Fallback(Circuit Switched Fallback) scheme, VoLGA(Voice overLTE via Generic Access), SRVCC(Single Radio Voice Call Continuity) and dual-mode dual-standby.Wherein, first three methods is all that multimode list is treated working method, in multimode terminal, synchronization only has a pattern in work, these schemes will inevitably need complicated multisystem Signalling exchange and complicated switching and network reselection flow process, thereby cause access and the handover delay grown, and finally have influence on user's experience.Dual-mode dual-standby mode is in a mobile phone, to place two to overlap independently physics transceiver module, and they can work in different networks at synchronization.As shown in Figure 1, independently module of two of GSM and LTE is housed in a mobile phone, they can realize transmission-receiving function respectively at synchronization in GSM and LTE network; These two modules connect by an application processor, thereby realize the mutual of two modules.Can find out, this scheme has been avoided complicated Signalling exchange and complicated switching flow, can effectively utilize each Internet resources, optimizes the deployment of miscellaneous service.
Although double model double standby phone can be avoided excessive complicated Signalling exchange and switching, brings user good business experience, when two patterns are worked simultaneously, the phase mutual interference between two radio frequencies is one of this programme key issue that need to solve.For double model double standby phone, the interference of two modules is mainly reflected in: when a module receives, another module is launched simultaneously, this will be interfered the module in accepting state, can greatly reduce the receiver sensitivity of this module thus, thereby cause the communication efficiency variation of mobile phone, even cannot work.
As shown in Figure 2, when not disposing LTE, the GSM base station in regional center after the network optimization can cover A+B region, and the GSM mobile handset user who singly treats all can realize effective call in A+B region; Yet, when disposing LTE and using GSM/LTE dual-mode handset to work simultaneously, because the radio-frequency transmissions of LTE will reduce GSM receiver sensitivity, therefore can cause the gsm module of this double-module double-standby cannot realize communication in B region.So the GSM network of having optimized will be affected due to the introducing of LTE double-module double-standby, cutting off rate increases, and call completing rate declines, thereby causes user's experience variation, and this will have a strong impact on the operation service quality of operator and user's satisfaction.Therefore,, when resolving two two modules of standby and working simultaneously, a module transmitting receives the radio frequency interference problem causing to another module, be to realize the important topic that dual-mode dual-standby scheme need to solve.
The main method that solves at present radio frequency interference has: 1, improve wiring in mobile phone; 2, improve Antenna Design, increase the isolation between antennas of different working modes; 3, choose reasonable frequency strengthens frequency spectrum isolation as far as possible.Although these methods can reduce interference strength, do not disturb and eliminate, when two patterns are worked simultaneously, the telex network in cell edge still can be influenced.

Embodiment
The present invention, mainly according to feature and the priority of two communication module bearer services of double-module double-standby, adopts central schedule mode, and the dual-mode of operation strategy of appropriate design reduces by two radio frequency mutual interference between pattern, and then assurance double-module double-standby is effectively worked.In the following description, this motion is that example is set forth mainly with GSM/LTE double model double standby phone, but the method that this motion proposes is not limited to GSM/LTE double model double standby phone.
embodiment of the method
As shown in Figure 3, double-mode and double-standby terminal control method of the present invention mainly comprises the following steps:
Step 302, determines the priority of two communication modules; Can determine according to the business that in double-mode and double-standby terminal, different communication module is carried, also can set according to actual needs;
Step 304, during to two communication module work, time priority communication module is analyzed the annoyance level of master-priority communication module;
Step 306, judges according to analytical structure whether two communication modules can work simultaneously; When two communication modules can be worked simultaneously, execution step 310; When two communication modules can not be worked simultaneously, execution step 308;
Step 308, controls master-priority communication module and preferentially carries out work;
Step 310, two communication modules are normally worked.
Preferably, step 306 specifically comprises: to described priority block, to the interference experience factor of master-priority module and master-priority module, select community quality assessment parameter resident and the required investigation of normally working to analyze.Concrete analysis comprises: relatively time priority communication module is selected the size of the resident quality assessment parameter in community to the interference experience factor of master-priority communication module and master-priority communication module, judges whether two communication modules can work simultaneously; When quality assessment parameter is all greater than described interference experience factor, judge that two communication modules work simultaneously; Otherwise judge that two communication modules can not work simultaneously;
Because double-module double-standby is that many nets are runed the solution under situation simultaneously, operator can come to the different business of each network positions according to covering, investment situation and main business revenue situation.After distinguishing priority, can when need to working simultaneously, two communication modules preferentially guarantee that the high communication module of priority carries out work.So, in double-module double-standby, the division of the priority of different communication module is the basis of supporting this motion, the work that guarantees the communication module that priority is higher is not subject to the interference of the communication module that priority is lower, and the method that this prioritization is carried out scheduling will make the work of double-module double-standby more effective.
In the present embodiment, not only the priority of communication module is divided, also further the disturbed condition between communication module is analyzed, when phase mutual interference hour, two communication modules are normally worked, when phase mutual interference is larger, when two communication modules can not be worked simultaneously, control the communication module that priority is higher and first carry out work.Like this, not only avoided two communication modules to interfere with each other the phenomenon that causes working, also guaranteed that the annoyance level that in double-mode and double-standby terminal, the communication module of groundwork is subject to is lower, can normally work, thereby improve the operating efficiency of double-mode and double-standby terminal, improved user's susceptibility.In the present embodiment, after step 310, also comprise, in the situation that two communication modules are worked simultaneously, the signal quality of monitoring master-priority communication module; When the signal quality of master-priority communication module is reduced to default threshold value, close time priority communication module, start timer; Detect the signal quality of master-priority communication module, when signal quality recovers, close time priority communication module until the work of master-priority communication module is complete; When search is during less than the community of master-priority communication module, after timer regularly finishes, recover time priority communication module work, when inferior priority communication module work is idle, find can be resident master-priority communication module community; By master-priority communication module work after switching or cell reselection, recover, close time priority communication module until the work of master-priority communication module is complete; Again judge whether two communication modules can work simultaneously.
In addition, in the present embodiment, by the signal quality of master-priority communication module is monitored, adjust in real time the result to interference analysis between two communication modules, according to the work of two communication modules of corresponding policy control, further guarantee the stability of double-mode and double-standby terminal work, improve the work quality of double-mode and double-standby terminal, improved user's susceptibility.
In the situation that two communication modules can be worked simultaneously, for two communication modules, mainly contain following working strategies:
(1), when the work of master-priority communication module, when inferior priority communication module is not worked, keep the work of master-priority communication module, if inferior priority communication module has work requirements, allow its work, regularly signal measurement independently, judges whether two communication modules can work simultaneously again;
(2) when master-priority communication module is not worked, during inferior priority communication module work, keep time priority communication module work, if master-priority communication module has work requirements, allow its work; Regularly signal measurement independently, judges whether two communication modules can work simultaneously again;
(3), when master-priority communication module is not worked, when inferior priority communication module is not worked yet, regularly signal measurement independently, upgrades and judges whether two communication modules can work simultaneously;
(4), when the work of master-priority communication module, during inferior priority communication module work, keep two communication modules to work simultaneously.
In the situation that two communication modules can not be worked simultaneously, for two communication modules, mainly contain following working strategies:
(1) when master-priority communication module work, when inferior priority communication module is not worked, keep the work of master-priority communication module, allow time communication module to receive signal, but do not allow transmitted signal, regularly signal measurement independently;
(2) when master-priority communication module is not worked, during inferior priority communication module work, keep time priority communication module communication, but master-priority communication module will inferior priority communication module not delivery time monitor, as master-priority communication module finds that there is new reception task, close at once time priority communication module, regularly signal measurement independently;
(3), when master-priority communication module is not worked, when inferior priority communication module is not worked yet, regularly signal measurement independently, as two communication modules have communication requirement simultaneously, only allows the communication of master-priority communication module.
In the present embodiment, by the priority of different communication module in double model double standby phone is judged, and the disturbed condition during further to the work of two communication modules is analyzed, under different operating states, formulate corresponding working strategies, two communication modules are controlled, to reduce the annoyance level that in double-mode and double-standby terminal, groundwork communication module is subject to, improve the work quality of double-mode and double-standby terminal, improved user's susceptibility.The GSM/LTE double model double standby phone of take is below specifically addressed the present embodiment double-mode and double-standby terminal control method as example.
For covering very perfect GSM network, its location is to ensure low speed and the high speech business of income; And for LTE network, its location is data service at a high speed.Because speech business is the main business revenue of operator source, and require very high to access rate, continuity; And data service is relatively less important business revenue source at present, for access rate and continuity, require high not as speech business.So, can think that speech business priority is now higher than data service.
As shown in Figure 4, the master controller of GSM/LTE double model double standby phone can be made following priority judgement: the speech business priority of GSM mode carrying is higher than the data service of LTE carrying, so when two communication modules of appearance are worked simultaneously, and when the signal that LTE module sends can cause interference to gsm module, need to use the scheduling strategy of preferential guarantee gsm module work.
In the present embodiment, according to inferior priority communication module, the interference analysis in advance of master-priority communication module is divided into the anticipation result of two standbies: 1. two communication modules can be worked simultaneously; 2. two communication modules can not be worked simultaneously.
As shown in Figure 4 may be simultaneously operated in the GSM/LTE double model double standby phone under GSM and two patterns of LTE, the speech business priority of gsm module carrying is higher than the data service of LTE module carrying.And due to the interference analysis of LTE module to GSM, two stand-by operation states can be divided in advance to two regions as shown in Figure 2: 1., in the A of region, gsm module and LTE module can be worked simultaneously; 2. in the B of region, the work of LTE module will cause gsm module normally to work.
In the present embodiment, main basis time priority communication module selects the resident parameter in community jointly to carry out interference analysis to the interference experience factor Δ of master-priority communication module and master-priority communication module.Interference factor when wherein Δ is the inferior priority communication module work drawing by great many of experiments chamber test synthesis, master-priority communication module being impacted is a strict empirical value.It is different due to each system, selecting the resident parameter in community, so Δ do not characterize a fixing parameter, but series of parameters, specifically by master-priority communication module, persistent district is carried out that parameter that quality evaluation adopts determines.The two standbies of GSM/LTE and UMTS/LTE of take are example (GSM and UMTS voice-bearer are master-priority communication modules):
(1) the two standbies of GSM/LTE
In gsm system, mobile phone uses " Path loss criterion " and descending rub-out signal counter (DSC:Downlink signaling failure conter) jointly to determine the signal quality [3GPP TS43.022: " Functions related to Mobile Station (MS) in idle mode and group receive mode "] of institute persistent district.Specifically refer to, when characterizing the dBm of level parameters C1>0(unit of " Path losscriterion "), during unison counter DSC>0, this gsm module need select this community resident, and can realize effectively work with greater probability.C1 is the value calculating according to received signal level herein; DSC can be greater than zero initial integer by one of Lookup protocol behind terminal persistent district, when this terminal can successfully demodulate the signal of its paging channel, this technology device increases 1(but surpasses never the integer of initial setting up, if the value of DSC itself is exactly initial value, it is 1 invalid to add); And when this terminal cannot Exact Solutions recalls the signal of its paging channel, DSC value subtracts 4.Therefore, disturbing experience factor Δ is the empirical value of corresponding quality assessment parameter, and interference experience factor herein has two parameters, the interference power values Δ of Ji YidBmWei unit
1with real integer Δ
2, be used in conjunction with quality assessment parameter C1 and the descending rub-out signal count value DSC of gsm system respectively, to determine the mode of operation of double-module double-standby.Judgment criterion is as follows:
Two communication modules of ■ can be worked simultaneously, i.e. two standbies are in region A: when C1-Δ
1>0 and DSC-Δ
2>0, or C1-Δ
1>=0 and DSC-Δ
2>=0 o'clock;
Two communication modules of ■ cannot be worked simultaneously, i.e. two standbies are in region B: when not meeting above-mentioned situation.
(2) the two standbies of UMTS/LTE
In UMTS system, in the situation that does not have LTE module to disturb, UMTS module complete that community is selected and gravity treatment after, determined that an optimum community carries out residently, now, this UMTS module can realize effectively work with very large probability.UMTS comprehensively judges the quality of selected community according to the parameter S rxlev in S criterion (SCriterion) and Squal, when not having LTE to disturb, selected resident optimum subdistrict meets: FDD community Srxlev>0 and Squal>0; TDD community Srxlev>0[3GPP TS25.304: " UE Procedures in IdleMode and Procedures for Cell Reselection in Connected Mode "].Srxlev refers to community selective reception grade point herein, and Squal is cell selection quality value.These two values are all that the quality of normally working desired signal energy and receiving signal according to terminal calculates jointly.Yet the interference producing after the work of LTE module can impact these two parameters.Therefore, Δ experience factor herein has two parameter Δs
1and Δ
2, being respectively the empirical value that parameter S rxlev and Squal are corresponding, unit is all dB, is used for characterizing the interference that LTE module causes UMTS module.Judgment criterion is as follows:
Two communication modules of ■ can be worked simultaneously, and two standbies are in A:FDD community, region Srxlev-Δ
1>0 and Squal-Δ
2>0, or Srxlev-Δ
1>=0 and Squal-Δ
2>=0 o'clock, or for TDD community, when Srxlev-Δ
1>=0 or Srxlev-Δ
1>=0 o'clock;
Two communication modules of ■ cannot be worked simultaneously, i.e. two standbies are in region B: while not meeting above-mentioned situation.
The present embodiment is not limited to above-mentioned two situations, the double-mode and double-standby terminal combining for variety classes communication module, the quality assessment parameter adopting is not identical yet, slightly different to the interference analysis method of two of double-mode and double-standby terminal terminals according to quality assessment parameter and interference experience factor yet.
It is to be noted, normal work in order to ensure master-priority communication module, above-mentioned interference experience factor Δ is a series of very strict numerical value that the critical condition test of great many of experiments chamber draws, and the application meeting of these numerical value guarantees the accuracy of anticipation result with maximum probability.
Also it is to be noted, because above-mentioned analytical method is to carry out community according to two standbies to select required cell quality evaluate parameter (not being actual service signal mass parameter) and experience factor Δ to estimate interference analysis result, although the Δ using ensures the accuracy of interference analysis result with maximum probability as far as possible, yet exist all the time certain probability to occur that the inaccurate or channel variation of result causes the renewal of interference analysis result to lag behind real channel variance very soon.In fact, the communication module of two standbies can be carried out quality to the service signal receiving and assessed (investigate to characterize the Rxlev of level and characterize the Rxqual parameter of BLER) when practical communication.
Therefore, also need to carry out the adjustment of anticipation result according to measured practical business signal quality in two stand-by operation.Preferably, in the present embodiment, also comprise: signal quality is monitored, regularly carried out independently signal measurement, obtain and there is no between communication module the quality assessment parameter of each communication module to institute persistent district under disturbed condition.And according to the quality assessment parameter after upgrading, rejudge two communication modules and whether can work simultaneously.
When GSM is different with LTE, under the prerequisite of work, the comprehensive judgement that the C1 measuring according to gsm module, DSC parameter and experience factor are made, is divided into double-module double-standby interference analysis result: 1. two communication modules can be worked simultaneously; 2. two communication modules cannot be worked simultaneously.Working strategies for GSM and LTE module is as follows:
One, under inferior priority communication module is disturbed, master-priority communication module can effectively be worked
1) two communication modules are all in off position: evaluate parameter C1 and the DSC of periodic measurement gsm module to persistent district, and according to measured value and experience factor Δ, carry out the anticipation result (whether two communication modules can work simultaneously) of modification region;
2) LTE module work, gsm module is not worked: keep LTE module normally to work, but want parameters C 1 and the DSC of periodic measurement gsm module under LTE module is disturbed, if judging gsm module, the actual value of these two parameters cannot reside in former community, revise double standby state---two communication modules cannot be worked simultaneously, in B region.Follow-uply according to the strategy under this anticipation result, carry out work;
3) gsm module work, LTE module is not worked: keep normally working, periodic measurement is to upgrade two standby interference analysis results;
4) two communication modules are worked simultaneously: keep normally working, but will monitor the service signal quality that GSM receives; As shown in Figure 5, main operational steps is as follows:
Step 502, gsm module and LTE module are worked simultaneously;
Step 504, monitoring GSM signal quality, need to not switch or during cell reselection, keep two communication module co-operation when GSM signal quality drops to; When dropping to, GSM signal quality need to switch or during cell reselection execution step 506;
Step 506, closes LTE, and starts timer;
Step 508 continues to detect GSM and receives signal in timer time section.
Step 510, if GSM signal quality recovers, closes LTE until gsm service finishes, and revises anticipation result and carries out work according to the strategy of this result;
Step 512, if closed after LTE, GSM works on by switching or cell reselection, closes LTE until gsm service finishes, and revises anticipation result and also according to the strategy of this result, carries out work;
Step 514, if GSM cannot realize and switching and cell reselection in timer time section, consider that GSM is without covering, now after finishing, recovers by timer the work of LTE module, and the time search of transmitted signal gap can resident GSM community in LTE module, after searching, measure and revise two standby anticipation results.
Two, under inferior priority communication module is disturbed, master-priority communication module cannot effectively be worked
1) two communication modules are all in off position: periodic measurement is to upgrade interference analysis result;
2) LTE module work, gsm module is not worked: keep normally working, but whether measure gsm module with the circulation of shorter interval called.If find calledly, close at once LTE module.If a certain moment gsm module is initiated caller, stop at once the work of LTE module.Periodic measurement is to upgrade anticipation result;
3) gsm module work, LTE module is not worked: keep gsm module work, if LTE has reception business, receive (if can normally receive); If LTE module has the demand of initiation business, it is carried out to random delay, until gsm module speech business finishes.Periodic measurement is to upgrade interference analysis result;
4) two communication modules are worked simultaneously: do not allow to occur this situation.
