The method for synchronous at the multi-card multi-standby terminal of embodiment of the present invention comprises: after the start, first terminal card is searched net and is resided in first sub-district; Control second terminal card and reside in said first sub-district, said second terminal card is terminal card suitable and the resident same cells of said first terminal card.
Said first terminal card can be for searching the terminal card of net and successful persistent district at first when starting shooting; When promptly starting shooting; All terminal cards are searched net and persistent district separately, and the terminal card of searching net and successful persistent district at first is first terminal card, and its resident successful sub-district is first sub-district.To be not suitable for the other-end card resident if search the net and the resident sub-district of terminal card of successful persistent district at first, and first terminal card also can be the terminal card of follow-up successful persistent district.
Said first terminal card also can be preassigned terminal card, and a terminal card when promptly starting shooting in many terminal cards of appointment searches net and the sub-district is resident, and its resident successful sub-district is first sub-district.
First terminal card also can be described as main card; If follow-up have an other-end card same cells resident with it (first sub-district); Then received and stored the system message of first sub-district by main card, the terminal card of other and the resident same cells of main card can directly read the system message of having stored.And the nearby region measurement result of first sub-district also only need report to main card, and the terminal card of other and the resident same cells of main card can be shared the nearby region measurement result of first sub-district.In addition, if the success of the cell synchronizing of many terminal cards in start back, the district reselecting of these terminal cards also can be synchronous, promptly when main card generation district reselecting, then the other-end card also gravity treatment to main card gravity treatment and resident sub-district.
The technical scheme of embodiment of the present invention can be applied to the diverse network standard, for example TD SDMA (TD-SCDMA) network, WCDMA (WCDMA) network, code division multiple access (CDMA) network, global system for mobile communications (GSM) network, LTE network etc.
Be fit to meet one of following condition with the terminal card (second terminal card) of the resident same cells of said first terminal card:
(1) said second terminal card belongs to identical operator with said first terminal card;
(2) the public land mobile communication network network of the resident sub-district (first sub-district) of said first terminal card sign (PLMN ID; Be used to identify operator; Hereinafter to be referred as network No.) be present in reciprocity Home PLMN (EHPLMN, HPLMN are meant the PLMN under the terminal card) tabulation of said second terminal card;
(3) network No. of said first sub-district is present in reciprocity PLMN (EPLMN) tabulation of said second terminal card;
(4) network No. of said first sub-district is the registration PLMN (RPLMN refers to the PLMN that the user successfully registered last time, and RPLMN possibly be HPLMN, EHPLMN, EPLMN, or allows any PLMN of this terminal card roaming) of said second terminal card;
(5) said second terminal card can't normally resident other sub-districts (resident other sub-districts failures); Promptly second terminal card is searched the net failure, and can not find can normally resident sub-district.
(6) said second terminal card registration or initiate professionally by subzone network refusal (as be in arrearage state or some other major reason cause can't be normally resident), usually in this case, first sub-district provide limited service can only for second terminal card.
In certain country, the cellular mobile communication networks of certain standard of certain operator is called as PLMN (Public Land Mobile Network, public land mobile network).The operator that PLMN is ratified by government or it, the network that provides the land mobile business purpose to set up and manage for the public.This network can wait other communication networks to interconnect with PSTN (Public Switched Telephone Network, PSTN), forms the communication network of whole distract or national scale.In CONTINENTAL AREA OF CHINA, have 3 PLMN at present.That is: the GSM/GPRS/EDGE of China Mobile (Global System For Mobile Communication/General Packet Radio Service/Enhanced Data Rate for GSM Evolution; Global mobile communication system/general grouping wireless service/enhanced data rates for gsm evolution) the GSM/GPRS network of network, CHINAUNICOM; CDMA-1X (Code Division Multiple Access 1X, code division multiple access 1X) network with China Telecom.
PLMN has distinguished the network of the different mode of different operators or same operator.For example; Can be used for distinguishing China Mobile and CHINAUNICOM; Also can distinguish TD-SCDMA (the Time Division-Synchronous Code Division Multiple Access of China Mobile; The code division multiple access that time-division is synchronous) network and GSM network are perhaps distinguished WCDMA (Wideband CDMA, WCDMA) or its GSM network of CHINAUNICOM.In fact, existing mobile phone is exactly through identification PLMN, and on mobile phone screen, shows what " 2G " or " 3G " identified.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 network evolvement network are Long Term Evolution (LTE, Long Term Evolution) system.
Relation by PLMN is classified, and can also be divided into HPLMN (Home Public Land Mobile Network, home public land mobile network network; Or be called Home PLMN); EHPLMN (Equivalent Home PLMN, reciprocity Home PLMN), EPLMN (Equivalent PLMN; Equity PLMN), RPLMN (Registered Public Land Mobile Network, registration PLMN) etc.This mainly is used for the relation between distinguishing terminal card and the PLMN.For example; The PLMN of the TD-SCDMA of China Mobile is the EPLMN of its GSM network, can simply think, mobile phone resides in the GSM and the TD-SCDMA of China Mobile; Be equivalent, the fees policy of the business of promptly chargeing (calling, send business such as note), allowing etc. is consistent.For SIM or usim card that China Mobile provides, China Mobile's GSM network is exactly its HPLMN, and TD-SCDMA then is EHPLMN.RPLMN is exactly the PLMN that succeeded in registration last time.
Below in conjunction with accompanying drawing, be that example is elaborated to embodiment of the present invention with the 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 method for synchronous of the double card double standby mobile phone of present embodiment comprises:
Step S11, start, terminal card 1 is searched net.Present embodiment, designated terminal card 1 is searched net when start in advance, like this for the multi-card multi-standby single-pass sytem, owing to have only a cover communication module, need not to adopt the mode of timesharing to come to switch in turn the net of searching of 2 cards, so it is faster to search network process.
Searching network process comprises:
(a) the reception signal strength of measuring all frequencies in the mobile phone band support is indicated (RSSI).Particularly, according to all frequencies in the network formats scanning band of mobile phone support, measure the RSSI of each frequency.
(b) judged whether that frequency need carry out Cell searching, then carried out (c), do not finished if then search network process if having.(for example-108dbm), then this frequency need carry out Cell searching if the RSSI of frequency is greater than predetermined threshold value; Otherwise, be not fit to resident sub-district, search the net failure.
(c) carry out Cell searching according to frequency of RSSI selective sequential from high to low, if search for successfully then carry out (d), if search failure then continue to select a frequency to carry out Cell searching.Particularly, the frequency that needs is carried out Cell searching sorts according to RSSI from high to low, at first selects the highest frequency of signal strength signal intensity to carry out Cell searching; Mobile phone receives the synchronizing information of sub-district, and (the GSM network is the synchronous channel SCH information transmitted; The TD-SCDMA network is a Primary Common Control Physical Channel P-CCPCH information transmitted, and the WCDMA network is a CPICH Common Pilot Channel CPICH information transmitted) after, then think to have searched this sub-district; Be the Cell searching success, carry out (d); If the Cell searching of this frequency failure then continues to select the high frequency of next RSSI to search for, up to the Cell searching success, perhaps all frequencies that need carry out Cell searching are all searched for failure.
(d) attempt the successful sub-district of resident search, if resident success then search the network process end, if resident failure then carry out (b).The process of persistent district comprises:
(d1) receive all system messages of this sub-district.Mobile phone is monitored the BCCH (BCCH) of this sub-district, receives the general information of BCCH transmission, i.e. system message.
(d2) if receive successfully then carry out (d3), if take defeat then resident failure.After if mobile phone receives whole system messages of BCCH, be stored in the terminal card 1, then carry out (d3); Otherwise persistent district failure.
(d3) if (the GSM network is for receiving signal strength signal intensity indication RSSI for the reception signal strength signal intensity of this sub-district; TD-SCDMA network, WCDMA network are received signal code power RSCP) meet the minimum access thresholding of network requirement; Lane place under the sub-district is not under an embargo; The sub-district does not get clogged (bar), and the network No. of sub-district belongs to the network (being that the sub-district can be resident) of terminal card 1 operator, then resident success; Otherwise resident failure.
Step S12, resident first sub-district of terminal card 1 success, then execution in step S13.In the present embodiment, the terminal card of specifying start to search net is a terminal card 1, and after its persistent district success, terminal card 1 is decided to be first terminal card, and its resident sub-district of success is first sub-district.If terminal card 1 is searched net and persistent district failure, then can continue to make terminal card 2 search net, if terminal card 2 successful persistent districts then are decided to be first terminal card with terminal card 2, its resident sub-district of success is first sub-district.Also can specify first terminal card 2 to search net in other embodiments, perhaps, terminal card 1 is searched net and persistent district respectively with terminal card 2, and searching the successful terminal card of net and persistent district at first is first terminal card, and its resident successful sub-district is first sub-district.
Step S13 judges whether terminal card 2 belongs to identical operator with terminal card 1, if execution in step S21 then, execution in step S14 then if not.International mobile subscriber identity (IMSI) through reading terminals card 1 and terminal card 2 can judge whether two cards belong to same operator; If two cards belong to identical operator; Then let terminal card 2 and terminal card 1 resident identical sub-district, promptly let terminal card 2 resident first sub-districts; If two cards belong to different operators, then continue to judge terminal card 2 whether satisfy other can with the situation of terminal card 1 resident same cells.
Whether step S14, the network No. of judging first sub-district are present in the EHPLMN tabulation or the EPLMN tabulation of terminal card 2, and perhaps whether the network No. of first sub-district is the RPLMN of terminal card 2, if execution in step S21 then, execution in step S15 then if not.If two cards belong to different operators; Then continue to judge whether to also have other possible situation; Can make terminal card 2 and terminal card 1 resident identical sub-district; Whether the network No. like first sub-district is present in the EHPLMN tabulation or EPLMN tabulation of terminal card 2, and perhaps whether the network No. of first sub-district is the RPLMN of terminal card 2.Wherein, the system message of the BCCH that receives through reading terminals card 1 of the network No. of first sub-district is obtained; The EHPLMN of terminal card 2 tabulation can obtain through reading terminals card 2, and the EPLMN tabulation of terminal card 2 can be read from the nonvolatile random access memory of mobile phone (NV is used for keeping the information of needs use after mobile phone start next time); The RPLMN of terminal card 2 is networks that terminal card was successfully registered for 2 last time, can obtain through reading terminals card 2.If the network No. of first sub-district is present in the EHPLMN tabulation or the EPLMN tabulation of terminal card 2, perhaps the network No. of first sub-district is the RPLMN of terminal card 2, then lets terminal card 2 and terminal card 1 resident identical sub-district, promptly lets terminal card 2 resident first sub-districts; If the network No. of first sub-district is neither in the EHPLMN of terminal card 2 tabulation, also not in the EPLMN tabulation, RPLMN that neither terminal card 2 then attempts letting terminal card 2 resident other available cell.
Step S15, terminal card 2 search net and resident other available cell, then execution in step S16.Terminal card 2 searches net and the persistent district process can refer step S11.
Step S16 judges whether success resident second sub-district (being other available cell) of terminal card 2, if execution in step S17 then, execution in step S21 then if not.If other sub-districts outside resident first sub-district of terminal card 2 successes, then terminal card 2 resident sub-districts are decided to be second sub-district, carry out the registration of second sub-district then; If terminal card 2 persistent districts failures, i.e. normal residing network then can only be limited resident, so also can force terminal card 2 resident first sub-districts, and terminal card 2 only can be initiated restricted service (like urgent call).
Step S17, terminal card 2 carry out the registration of second sub-district, then execution in step S18.
Step S18 judges the whether success of terminal card 2 registration second sub-district, if execution in step S19 then, execution in step S21 then if not.If terminal card 2 is accomplished the registration of second sub-district, then terminal card 2 standbies are at the network of second sub-district; If terminal card 2 registrations are in the arrearage state by the network refusal like terminal card 2, then can only be limited resident, therefore also can force terminal card 2 resident first sub-districts, terminal card 2 only can be initiated restricted service.
Step S19, terminal card 1 carry out the registration of first sub-district.After terminal card 1 was accomplished the registration of first sub-district, terminal card 1 resided in different districts respectively with terminal card 2, and terminal card 1 standby is at the network of first sub-district, and terminal card 2 standbies are at the network of second sub-district.
Step S21, terminal card 2 resident first sub-districts, then execution in step S22.If terminal card 1 belongs to same operator with terminal card 2; Perhaps the network No. of first sub-district is present in the EHPLMN tabulation of terminal card 2, and perhaps the network No. of first sub-district is present in the EPLMN tabulation of terminal card 2, and perhaps the network No. of first sub-district is the RPLMN of terminal card 2; Perhaps terminal card 2 resident second sub-district failures; Perhaps the network of terminal card 2 registrations second sub-district is rejected, and then forces terminal card 2 and terminal card 1 resident identical sub-district, i.e. first sub-district.Owing to search in the process of net and resident first sub-district of success at terminal card 1; Stored the system message of first sub-district that receives; Therefore terminal card 2 can directly read the system message of first sub-district from terminal card 1, and the time of terminal card 2 resident first sub-districts significantly shortens like this.
Step S22, terminal card 1 carry out the registration of first sub-district, and terminal card 2 carries out the registration of first sub-district.Can force two to block resident same cells during resident same cells when judging terminal card 1 and terminal card 2; After terminal card 1 is accomplished the sub-district registration in turn with terminal card 2, terminal card 1 and terminal card 2 all standby at the network of first sub-district, mobile phone monitoring seek channel (PCH); Can receive the beep-page message of two cards simultaneously; And notify two cards respectively, and improved the paging receiving efficiency like this, avoided call loss.And two cards can be shared nearby region measurement information, have improved efficiency of measurement; When district reselecting takes place in terminal card 1; Terminal card 2 also gravity treatment synchronously that is to say, after start to terminal card 1 gravity treatment and resident sub-district; If judge that terminal card 1 and terminal card 2 can be resident during same cells, terminal card 1 can reside in identical sub-district all the time synchronously with terminal card 2.
Need to prove; The foregoing description is to be that example specifies with the dual-card dual-standby terminal; In fact; The technical scheme of embodiment of the present invention equally also is applicable to the multi-card multi-standby terminal of supporting that two terminal cards are above, when start, have a terminal card (first terminal card) to search net and persistent district success after, as long as one or more terminal card (being referred to as second terminal card) that the resident sub-district of first terminal card can be fit in the other-end card is resident; Then can force this or many terminal cards to reside on the resident sub-district of first terminal card, many terminal cards are accomplished the sub-district registration in turn then.
