(3) network No. of described first community is present in reciprocity PLMN (EPLMN) list of described second terminal card;
(4) network No. of described first community is the registration PLMN (RPLMN of described second terminal card, refer to the PLMN of user's successful registration last time, RPLMN may be HPLMN, EHPLMN, EPLMN, or any PLMN allowing this terminal card to roam);
(5) described second terminal card cannot normally other communities resident (other community failures resident); Namely the second terminal card is searched and is netted unsuccessfully, can not find can be normally resident community.
(6) described second terminal card registration or the business of initiation are by subzone network refusal (as be in arrearage state or some other major reason cause cannot be normally resident), usually in this case, the first community provides limited service can only to the second terminal card.
In certain country, the cellular mobile communication networks of certain standard of certain operator is called as PLMN (PublicLandMobileNetwork, public land mobile network).The operator that PLMN is ratified by government or it is the network that the public provides land mobile business purpose and set up and manage.This network can interconnect with other communication networks such as PSTN (PublicSwitchedTelephoneNetwork, PSTN), forms the communication network of whole distract or Country Scale.In CONTINENTAL AREA OF CHINA, have 3 PLMN at present.That is: GSM/GPRS/EDGE (the GlobalSystemForMobileCommunication/GeneralPacketRadioSer vice/EnhancedDataRateforGSMEvolution of China Mobile, global mobile communication system/general grouping wireless service/enhanced data rates for gsm evolution) network, CHINAUNICOM GSM/GPRS network, with CDMA-1X (CodeDivisionMultipleAccess1X, the code division multiple access 1X) network of China Telecom.
PLMN has distinguished the network of the different mode of different operators or same operator.Such as, can be used for distinguishing China Mobile and CHINAUNICOM, also TD-SCDMA (the TimeDivision-SynchronousCodeDivisionMultipleAccess of China Mobile can be distinguished, the code division multiple access of time division synchronous) network and GSM network, or distinguish WCDMA (WidebandCDMA, Wideband Code Division Multiple Access (WCDMA)) or its GSM network of CHINAUNICOM.In fact, existing mobile phone is exactly by identifying PLMN, and on mobile phone screen, shows " 2G " or " 3G " identify.What 2G (second generation) referred to is exactly GSM, CDMA-1X network, and TD-SCDMA, WCDMA etc. are 3G (third generation) network.TD-SCDMA and WCDMA e-learning quality network, is Long Term Evolution (LTE, LongTermEvolution) system.
Classify by the relation of PLMN, HPLMN (HomePublicLandMobileNetwork can also be divided into, home public land mobile network network, or be called Home PLMN), EHPLMN (EquivalentHomePLMN, reciprocity Home PLMN), EPLMN (EquivalentPLMN, equity PLMN), RPLMN (RegisteredPublicLandMobileNetwork, registration PLMN) etc.This is mainly used to the relation between distinguishing terminal card and PLMN.Such as, the PLMN of the TD-SCDMA of China Mobile is the EPLMN of its GSM network, can simply think, mobile phone resides in GSM and TD-SCDMA of China Mobile, be equivalent, i.e. the fees policy of the business of charging (call, send the business such as note), permission etc. is consistent.The SIM provided for China Mobile or usim card, China Mobile's GSM network is exactly its HPLMN, TD-SCDMA is then EHPLMN.RPLMN is exactly the PLMN succeeded in registration last time.
Below in conjunction with accompanying drawing, be described in detail to embodiment of the present invention for double card double standby mobile phone, double card double standby mobile phone comprises terminal card 1 and terminal card 2.
Please refer to Fig. 1, the synchronous method of the double card double standby mobile phone of the present embodiment comprises:
Step S11, start, terminal card 1 searches net.The present embodiment, in advance designated terminal card 1 start shooting time search net, like this for multi-card multi-standby single-pass sytem, owing to only having a set of communication module, without the need to adopt the mode of timesharing switch in turn 2 card search net, therefore search network process faster.
Search network process to comprise:
A () measures Received signal strength field intensity instruction (RSSI) of all frequencies in mobile phone band support.Particularly, all frequencies in the network formats scanning band supported according to mobile phone, measure the RSSI of each frequency.
B () has judged whether that frequency needs to carry out Cell searching, if having, carry out (c), if not, searches network process and terminates.If the RSSI of frequency is greater than predetermined threshold value (such as-108dbm), then this frequency needs to carry out Cell searching; Otherwise, be not applicable to resident community, search and net unsuccessfully.
C () carries out Cell searching according to RSSI selective sequential frequency from high to low, if search for successfully, carry out (d), if search for unsuccessfully, continues selection frequency and carries out Cell searching.Particularly, sort needing the frequency carrying out Cell searching from high to low according to RSSI, first the highest frequency of signal strength signal intensity is selected to carry out Cell searching, mobile phone receive community synchronizing information (GSM network be synchronous channel SCH transmission information, TD-SCDMA network is the information that Primary Common Control Physical Channel P-CCPCH transmits, WCDMA network is the information of Common Pilot Channel CPICH transmission) after, then think and searched this community, i.e. Cell searching success, carries out (d); If the Cell searching failure of this frequency, then continue to select the high frequency of next RSSI to search for, until Cell searching success, or all frequencies carrying out Cell searching that needs all search for failure.
D () attempts the successful community of resident search, if resident success, search network process and terminate, if resident failure, carries out (b).The process of persistent district comprises:
(d1) all system messages of this community are received.The Broadcast Control Channel (BCCH) of this community monitored by mobile phone, receives the general information of BCCH transmission, i.e. system message.
(d2) if receive successfully, carry out (d3), if taken defeat, resident failure.If after mobile phone receives whole system messages of BCCH, be stored in terminal card 1, then carry out (d3); Otherwise persistent district failure.
(d3) if (GSM network is received signal strength indicator RSSI to the received signal strength of this community, TD-SCDMA network, WCDMA network are received signal code power RSCP) meet the minimum access thresholding of network requirement, lane place belonging to community is not prohibited, community does not get clogged (bar), the network No. of community belongs to the network (namely community can be resident) of terminal card 1 operator, then resident success; Otherwise resident failure.
Step S12, resident first community of terminal card 1 success, then performs step S13.In the present embodiment, the terminal card of specifying start to search net is terminal card 1, and after its persistent district success, terminal card 1 is decided to be first terminal card, and its resident community of success is the first community.If terminal card 1 searches net and persistent district failure, then can continue to make terminal card 2 carry out searching net, if the successful persistent district of terminal card 2, then terminal card 2 is decided to be first terminal card, its resident community of success is the first community.Also first terminal card 2 can be specified in other embodiments to carry out searching net, or terminal card 1 and terminal card 2 carry out searching net and persistent district respectively, searching the successful terminal card of net and persistent district is at first first terminal card, and its resident successful community is the first community.
Step S13, judges whether terminal card 2 belongs to identical operator with terminal card 1, if then perform step S21, then performs step S14 if not.Can judge whether two cards belong to same operator by the international mobile subscriber identity (IMSI) of reading terminals card 1 and terminal card 2, if two cards belong to identical operator, then allow the resident identical community of terminal card 2 and terminal card 1, namely allow resident first community of terminal card 2; If two cards belong to different operators, then continue judge terminal card 2 whether meet other can with the situation of the resident same cells of terminal card 1.
Step S14, judges whether the network No. of the first community is present in EHPLMN list or the EPLMN list of terminal card 2, or whether the network No. of the first community is the RPLMN of terminal card 2, if then perform step S21, then performs step S15 if not.If two cards belong to different operators, then continue to judge whether other possible situations in addition, the resident identical community of terminal card 2 and terminal card 1 can be made, in the EHPLMN the list whether network No. as the first community is present in terminal card 2 or EPLMN list, or whether the network No. of the first community is the RPLMN of terminal card 2.Wherein, the system message of BCCH that the network No. of the first community is received by reading terminals card 1 obtains; The EHPLMN list of terminal card 2 can be obtained by reading terminals card 2, and the EPLMN list of terminal card 2 can be read from the nonvolatile random access memory of mobile phone (NV needs the information of use for retaining mobile phone next time after start); The RPLMN of terminal card 2 is terminal card 2 networks that last time, successful registration was crossed, and can be obtained by reading terminals card 2.If the network No. of the first community is present in EHPLMN list or the EPLMN list of terminal card 2, or the network No. of the first community is the RPLMN of terminal card 2, then allow the resident identical community of terminal card 2 and terminal card 1, namely allow resident first community of terminal card 2; If the network No. of the first community is neither in the EHPLMN list of terminal card 2, also not in EPLMN list, neither the RPLMN of terminal card 2, then attempt allowing terminal card 2 other available cell resident.
Step S15, terminal card 2 searches net and other available cell resident, then performs step S16.Terminal card 2 searches net and persistent district process can refer step S11.
Step S16, judges whether successful resident second community (i.e. other available cell) of terminal card 2, if then perform step S17, then performs step S21 if not.If other communities outside resident first community of terminal card 2 success, then the community that terminal card 2 is resident is decided to be the second community, then carries out the second cell registration; If the failure of terminal card 2 persistent district, namely cannot normal residing network, then can only be limited resident, therefore also can force resident first community of terminal card 2, terminal card 2 only can initiate restricted service (as urgent call).
Step S17, terminal card 2 carries out the second cell registration, then performs step S18.
Step S18, judges whether successfully terminal card 2 registers the second community, if then perform step S19, then performs step S21 if not.If terminal card 2 completes the second cell registration, then the standby network in the second community of terminal card 2; If terminal card 2 is registered refused by network, as terminal card 2 is in arrearage state, then can only be limited resident, therefore also can force resident first community of terminal card 2, terminal card 2 only can initiate restricted service.
Step S19, terminal card 1 carries out the first cell registration.After terminal card 1 completes the first cell registration, terminal card 1 and terminal card 2 reside in different districts respectively, the standby network in the first community of terminal card 1, the standby network in the second community of terminal card 2.
Step S21, resident first community of terminal card 2, then performs step S22.If terminal card 1 and terminal card 2 belong to same operator, or the network No. of the first community is present in the EHPLMN list of terminal card 2, or the network No. of the first community is present in the EPLMN list of terminal card 2, or the network No. of the first community is the RPLMN of terminal card 2, or the resident second community failure of terminal card 2, or the network that terminal card 2 registers the second community is rejected, then force terminal card 2 identical community resident with terminal card 1, i.e. the first community.Due to search at terminal card 1 net and success resident first community process in, store the system message of the first community of reception, therefore terminal card 2 directly can read the system message of the first community from terminal card 1, and the time of resident first community of such terminal card 2 significantly shortens.
Step S22, terminal card 1 carries out the first cell registration, and terminal card 2 carries out the first cell registration.When judging that terminal card 1 and terminal card 2 can force two to block resident same cells during resident same cells, after terminal card 1 and terminal card 2 complete cell registration in turn, terminal card 1 and all standby network in the first community of terminal card 2, mobile phone monitoring seek channel (PCH), the beep-page message of two cards can be received simultaneously, and notify two cards respectively, which enhance paging receiving efficiency, avoid call loss.And, two cards can share neighbor measurement information, improve measurement efficiency, when there is cell reselection in terminal card 1, terminal card 2 also can synchronously gravity treatment to terminal card 1 gravity treatment and resident community, that is, after powering, if judge terminal card 1 and terminal card 2 can resident same cells time, terminal card 1 and terminal card 2 can synchronously reside in identical community all the time.
It should be noted that, above-described embodiment has been described in detail for dual-card dual-standby terminal, in fact, the technical scheme of embodiment of the present invention is equally also applicable to the Multi-card multi-standby terminal of more than support two terminal cards, have upon power-up a terminal card (first terminal card) search net and persistent district success after, as long as one or more terminal card (being referred to as the second terminal card) that the resident community of first terminal card can be applicable in other-end card is resident, this or multiple terminal cards then can be forced to reside on the resident community of first terminal card, then multiple terminal cards complete cell registration in turn.
