Embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.

Embodiment one

Embodiments of the invention provide a kind of network registering method, as shown in figure 1, including：

101st, when terminal is resident in the PLMN of roaming place, terminal receives the location area information of the roaming place from the PLMN.

102nd, terminal obtains its subscription data, the subscription data each IMSI and corresponding relation in the position area contracted in multiple IMSI comprising the terminal.

103rd, terminal is according to location area information and subscription data, it is determined that IMSI corresponding with the location area information.

If the 104, the first IMSI that terminal is being used and the IMSI determined are inconsistent, the first IMSI used is then switched to twoth IMSI consistent with the IMSI determined by terminal.

105th, terminal is registered to the PLMN of the roaming place by the 2nd IMSI.

The terminal being related in the embodiment of the present invention, it can be the mobile terminal for supporting multiple IMSI, for example, SVLTE terminals can support 3 IMSI, it is the own IMSI1 of China Telecom respectively, IMSI1 can be used for the networks such as the HRPD (High Rate Packet Data, HRPD) on ground such as access China's Mainland；It can also the own IMSI2 of branch China Telecom, IMSI2 can be used for the networks such as the LTE on ground such as access China's Mainland；In addition, it can also support the IMSI3 of Waduven's (US carrier), IMSI3 can be used for the G/W (i.e. 3G network/WCDMA networks) in access roaming region, that is this SVLTE terminals are both PLMN1 (the Public Land Mobile Network belonging to IMSI1, public land mobile network) contracting terminal, while being also PLMN2 belonging to IMSI2 and IMSI3 and PLMN3 contracting terminal.

It can be seen that, when this multiple IMSI of support terminal roaming to the roaming place contracted, especially under international roaming scene, the terminal can switch to the IMSI of roaming place from the first IMSI being being currently used, the IMSI of roaming place can be thus used to carry out network registry in the roaming place, to ensure the normal communication of user.

In a step 101, the network that terminal can be searched for regularly in current environment automatically, when terminal enters roaming place or started shooting in roaming place, the corresponding PLMN that can be provided according to the strategy of terminal built-in (such as selection signal most strong network) selection roaming place is resident, and in order to register the corresponding network of roaming place to ensure normal communication of the terminal in roaming place, terminal needs that the illegal IMSI used (i.e. the first IMSI) is switched into the legal IMSI in roaming place (i.e. the 2nd IMSI) in time, in order to which SS later registers the network of roaming place using the 2nd legal IMSI.

Now, terminal can receive the location area information of the roaming place from resident PLMN, for example, current PLMN MCC (Mobile Country Code, Mobile Country Code MCC) is 310 (representing that the current position of terminal is located at U.S. locations).

Wherein, position area (LA, Location Area) is the set of one group of cell in GSM, and the effect in set location area is the position for enabling mobile switch or mobile switching centre to know terminal in time.

Location area information, may be used to indicate the information in terminal belonging positions area, for example, location area information can refer to the MCC of terminal, CHINESE REGION is referred to when MCC is 460, U.S. locations are referred to when MCC is 310；Location area information can also refer to the LAC (Location Area Code, position code) or LAI (Location Area Identity, band of position ID) of terminal, wherein, LAI is MCC, MNC and LAC combination.

Further, in a step 102, terminal can also obtain its subscription data, due to User is before using terminal is communicated, need to complete to contract with each operator, for this multiple IMSI of support terminal, these terminals need the different operators with country variant to contract respectively, it could cross when ensureing that user roams to roaming place, the subscription data contracted according to terminal obtains the service on the ground in time, therefore, when terminal is resident in the PLMN of roaming place, terminal can also get the subscription data of the roaming place.

Wherein, the subscription data each IMSI and corresponding relation in the position area contracted in multiple IMSI comprising the terminal, further, the corresponding relation of operator that can also be further comprising each IMSI and the different regions contracted in the subscription data, as shown in table 1, the terminal can support 3 operators to distinguish corresponding 3 IMSI.

Table 1

IMSI1	China Mobile
IMSI1	China Mobile	IMSI2	CHINAUNICOM
IMSI3	Waduven of the U.S.	IMSI2	CHINAUNICOM

Certainly, the information such as conditions of service, the service range that can also have been contracted in the subscription data including the operator of terminal and roaming place.

For example, the IMSI2 that terminal A is supported has contracted short message and session services with the operator of Waduven in the U.S., that is terminal A can enjoy short message and session services after completing local network registry using IMSI2 in the U.S., so, when terminal A roams to the U.S., terminal A subscription data is obtained, such as, the subscription data is the IMSI lists that operator of Waduven allows to use in the U.S., legitimacies of the IMSI that terminal just can used according to IMSI lists judgement terminal A in the U.S..

In step 103, after terminal gets location area information and the subscription data of roaming place, just it can judge whether the first IMSI that terminal is being used is legal in roaming place according to the location area information and subscription data of roaming place, the IMSI corresponding to the location area information that gets is determined, whether the first IMSI used with terminal is consistent.

Exemplary, if the position of the location area information instruction terminal for the roaming place that terminal is received from resident PLMN is in U.S. locations, and the IMSI for the CHINESE REGION that it is 460 that the IMSI1 that terminal is being used, which is MCC, subscription data so according to table 1, IMSI3 corresponding to the location area information of the roaming place and the IMSI1 that terminal is being used are not consistent The IMSII that i.e. terminal is being used is illegal in roaming place.

It should be noted that, the first IMSI that involved terminal is being used in the embodiment of the present invention may particularly include two kinds of situations, when terminal is being started shooting after entering roaming place, first IMSI can be the last used IMSI of terminal, when being in open state when terminal enters roaming place, this is repeated no more in the IMSI that first IMSI is then using for terminal, subsequent embodiment.

Further, after execution of step 103, if the first IMSI that terminal is being used is consistent with the IMSI determined, the first IMSI that i.e. terminal is being used is legal in roaming place, so, terminal directly can carry out location update operations using the PLMN of the legal roaming place, and complete to register the PLMN of roaming place network registry.

Accordingly, if the first IMSI that is using of terminal and the IMSI determined are inconsistent, i.e., the first IMSI that terminal is being used is illegal in roaming place, so, as described in step 104, now, the first IMSI used is switched to twoth IMSI consistent with the IMSI determined by terminal.

Still continue to use the example in step 103, subscription data according to table 1, IMSI3 corresponding to the location area information of the roaming place and the IMSI1 that terminal is being used are not consistent, the IMSI1 that i.e. terminal is being used is illegal in roaming place, therefore, card module in terminal instruction terminal switches to the IMSI1 that terminal is being used the IMSI3 corresponding to the location area information of the roaming place, in order to which terminal completes the network registry flow of roaming place using the IMSI3 after switching.

In addition, if the first IMSI that terminal is being used and the IMSI determined are inconsistent, terminal is when performing step 104, the limited service that the PLMN of roaming place where can also accessing is provided, so, terminal can ensure that user carries out the business such as urgent call using the limited service of roaming place while IMSI is switched.

Certainly, in embodiments of the present invention, terminal judges the first IMSI used in the whether legal method in roaming place according to subscription data, it is applicable not only to support multiple IMSI terminal to carry out the scene of IMSI switchings, for any terminal, the legitimacy for the first IMSI that usable this method is being used terminal judges before location update operations are carried out, terminal just can launch position renewal operation only in the case where the first IMSI is legal IMSI To complete network registry of the terminal in current resident network, once the first IMSI is illegal IMSI, terminal just registers the limited service of resident network, so, avoid terminal in the prior art and use the trial registered network that illegal IMSI is repeated, and cause the problem of network registry speed declines, while Internet resources can be saved.

In step 105, after the first current IMSI is switched to two legal IMSI of roaming place by terminal, the legal IMSI supported by the 2nd IMSI after switching by the network of roaming place, therefore, terminal can use the 2nd IMSI launch positions after switching to update operation, and then complete the network registry in the PLMN of roaming place.

In addition, the embodiment of the present invention also provides a kind of network registering method, specifically, as shown in Fig. 2 can also carry out step 100 to 300 performing step 101 to terminal before 103.

100th, terminal receives the information of roaming place of user's input.

200th, terminal is according to information of roaming place, and the corresponding IMSI of the information of roaming place is searched in corresponding relation of the preset roaming place with IMSI.

300th, the IMSI used before being powered off, is switched to the corresponding IMSI of the information of roaming place of this in step 200 by terminal.

So, when the information of roaming place that terminal is inputted according to user reaches the roaming place, above-mentioned steps 101 to 103 can be continued executing with, until terminal is according to location area information and subscription data, it is determined that IMSI corresponding with the location area information, now, due in step 300, the IMSI used is switched to the corresponding IMSI of the information of roaming place of this in step 200 by terminal, therefore, the first IMSI that terminal is being used when the PLMN of roaming place is resident is the corresponding IMSI of the information of roaming place in step 200, so, terminal determine the first IMSI used it is consistent with the IMSI determined after, the IMSI used without switching, and the PLMN of the roaming place can be directly registered to by the corresponding IMSI of the information of roaming place.

Embodiments of the invention provide a kind of network registering method, terminal is by obtaining the location area information of its subscription data and roaming place, it is determined that IMSI corresponding with the location area information, the subscription data each IMSI and corresponding relation in the position area contracted in multiple IMSI comprising terminal, if the first IMSI that the terminal is being used and the IMSI determined are inconsistent, the IMSI that the first IMSI used is then directly switched to and determined by terminal The 2nd consistent IMSI, and use the 2nd IMSI registration roaming place networks after switching, so, without as in existing protocol, terminal needs to use the network for registering roaming place that incorrect IMSI is repeated before IMSI switchings are carried out, until the network for all standards that traversal terminal is supported, it was found that after the network of all standards all registration failures, IMSI switchings are just carried out according to the location area information of roaming place, it can be seen that, this programme solve terminal in the prior art taken when carrying out IMSI switchings it is long and the problem of cause the network registry time to increase, the utilization rate of Internet resources is improved simultaneously.

Embodiment two

Embodiments of the invention provide a kind of network registering method, as shown in figure 3, including：

201st, terminal determines whether to receive the information of roaming place of user's input.

If 202a, receiving the information of roaming place of user's input, terminal searches the corresponding IMSI of the information of roaming place then according to information of roaming place in corresponding relation of the preset roaming place with IMSI.

The IMSI used before being powered off, is switched to the corresponding IMSI of the information of roaming place in step 202a by 203a, terminal.

204a, when terminal is started shooting in roaming place and PLMN in roaming place is resident, the location area information of the roaming place is received from the PLMN.

205a, terminal obtain its subscription data, the subscription data each IMSI and corresponding relation in the position area contracted in multiple IMSI comprising the terminal.

206a, terminal are according to location area information and subscription data, it is determined that IMSI corresponding with the location area information, and determine that the corresponding IMSI of the location area information is the corresponding IMSI of the information of roaming place in step 202a.

207a, terminal are registered to the PLMN of the roaming place by the corresponding IMSI of the information of roaming place.

If 202b, the information of roaming place for being not received by user's input, when terminal is resident in the PLMN of roaming place, terminal receives the location area information of the roaming place from the PLMN.

203b, terminal obtain its subscription data, the subscription data each IMSI and corresponding relation in the position area contracted in multiple IMSI comprising the terminal.

204b, terminal according to location area information and subscription data, it is determined that with the location area information Corresponding IMSI.

If the first IMSI that 205b, terminal are being used and the IMSI determined are inconsistent, the first IMSI used is then switched to twoth IMSI consistent with the IMSI determined by terminal.

206b, terminal access the limited service that the PLMN of the roaming place is provided.

207b, terminal are registered to the PLMN of the roaming place by the 2nd IMSI.

If the first IMSI that 208b, terminal are being used is consistent with the IMSI determined, terminal is then registered to the PLMN of the roaming place by the first IMSI.

In step 201, when user goes on a journey to before roaming place, the information of roaming place for the roaming place that will be reached can be inputted in terminal, for example, user can input the information of roaming place of " roaming place is the U.S. " in terminal, if terminal receives the information of roaming place of user's input, step 202 is performed；If terminal is not received by the information of roaming place of user's input, step 203 is performed to 209.

In step 202a, if terminal receives the information of roaming place of user's input, terminal just can search the corresponding IMSI of the information of roaming place according to the information of roaming place in corresponding relation of the preset roaming place with IMSI.

In step 203, terminal is before being powered off, the IMSI used switched into the corresponding IMSI of the information of roaming place of this in step 202, it is to avoid when terminal attempts the network that all terminals of registration can search for using the incorrect IMSI not switched in roaming place, the time overhead brought.

For example, user needs to go on business from Beijing to Washington, DC, so, user can input the information of roaming place of Washington, DC, the information of roaming place for the Washington, DC that terminal is inputted according to user, in the corresponding relation list of the information of roaming place and IMSI of terminal preset directly in terminal, determine the IMSI2 that the IMSI of Washington, DC is supported by terminal, so, before terminal closedown goes to roaming place, terminal switches to the first IMSI used the 2nd IMSI of roaming place.

It can be seen that, terminal just completes IMSI switching flows before roaming place is roamed to, when the information of roaming place that terminal is inputted according to user reaches the roaming place, terminal can directly complete the network registry of roaming place using the 2nd IMSI after switching, greatly reduce terminal and exist The network registry time of roaming place.

After execution of step 203a, terminal can continue executing with above-mentioned steps 204a to 207a, until terminal is registered to the PLMN of the roaming place by the corresponding IMSI of the information of roaming place, the related elaboration of step 100-300 in embodiment one is for details, reference can be made to, therefore here is omitted.

In step 202b, if terminal is not received by the information of roaming place of user's input, then, when terminal is resident in the PLMN of roaming place, terminal can receive the location area information of the roaming place from resident PLMN, and the step can be found in the step 101 in embodiment one, therefore here is omitted.

In step 203b, when terminal is resident in the PLMN of roaming place, terminal can also obtain its subscription data, the subscription data each IMSI and corresponding relation in the position area contracted in multiple IMSI comprising the terminal.

It specifically, the subscription data can be preset in terminal, can also be stored in network side equipment, when PLMN of the terminal in roaming place is resident, terminal obtains the subscription data, and judge according to the subscription data legitimacy of the first currently used IMSI of terminal.

It should be noted that, the PLMN of the roaming place can also be included in the subscription data allows the IMSI lists used, so, when terminal is resident in the PLMN of roaming place, terminal obtains the IMSI lists from the PLMN, now, if the first currently used IMSI of terminal is in the IMSI lists, then the first IMSI of explanation is legal IMSI in the PLMN, if the first currently used IMSI of terminal is not in the IMSI lists, then the first IMSI of explanation is illegal IMSI in the PLMN, so, terminal can determine the 2nd legal IMSI of the terminal in the PLMN according to the location area information of the IMSI lists and roaming place.

In step 204b, after terminal gets location area information and the subscription data of roaming place, just it can judge whether the first IMSI that terminal is being used is legal in roaming place according to the location area information and subscription data of roaming place, the IMSI corresponding to the location area information that gets is determined, whether the first IMSI used with terminal is consistent.The step can be found in the step 103 in embodiment one, therefore here is omitted.

Further, after execution of step 204b, if the first IMSI that is using of terminal and the IMSI determined are inconsistent, step 205b to 207b is performed, if terminal The first IMSI used is consistent with the IMSI determined, then performs step 28b.

In step 205b, if the first IMSI that terminal is being used and the IMSI determined are inconsistent, the first IMSI that i.e. terminal is being used is illegal in roaming place, then, the first IMSI used can be switched to twoth IMSI consistent with the IMSI determined by terminal.

In step 206b, terminal is when performing step 205b, the limited service that the PLMN of roaming place where can also accessing is provided, so, and terminal can ensure that user carries out the business such as urgent call using the limited service of roaming place while IMSI is switched.

Exemplary, reference can be made to Fig. 4 and embodiment one, Registering modules and mobile management module are provided with terminal, after terminal gets the location area information of subscription data and roaming place, legitimacies of the first IMSI that mobile management module is being used terminal in roaming place judges, judge whether the first IMSI that terminal using is consistent with the IMSI determined, if the first IMSI and the IMSI determined are inconsistent, illustrate that the first IMSI that terminal is being used is illegal in roaming place, so, terminal just can be while the limited service of roaming place be registered, the first IMSI used is switched into twoth IMSI consistent with the IMSI determined, so, terminal just can use networks of the 2nd IMSI after switching to the network device registration roaming place.

And in existing protocol, still reference can be made to Fig. 4, web search can be carried out when terminal roams to roaming place from CHINESE REGION, simultaneously, Registering modules can be attempted to carry out network registry course to the multiple network standard once used respectively, such as LTE network of CHINESE REGION (MCC is 460), the GSM network of CHINESE REGION and the UMTS network of CHINESE REGION etc., but, these networks of CHINESE REGION are not supported in roaming place, therefore, after these tentative registrations all fail, the Registering modules of terminal can also be attempted to be registered in roaming place (such as U.S. locations respectively, MCC is the known network 310) searched, because the first IMSI that terminal is being used is illegal IMSI, when attempt to be registered in the known network that roaming place searched all fail after, terminal can just go to register the limited service of roaming place, and complete follow-up IMSI switching flows, finally, using network from the 2nd IMSI after switching to the network device registration roaming place.

As can be seen that embodiments of the invention pass through the first IMSI that is using terminal Legitimacy in roaming place is judged, quick IMSI switching flows can be achieved, the utilization rate of Internet resources is improved.

In step 207b, when terminal indicates that the first current IMSI is switched to the 2nd legal IMSI of roaming place by card module, the legal IMSI supported by the 2nd IMSI after switching by the network of roaming place, therefore, terminal can use the 2nd IMSI after switching to carry out location update operations, and the PLMN of the roaming place is registered, to ensure normal communication of the user in roaming place.

Need further exist for explanation be, if terminal has been switched off before roaming place carries out registered network, i.e. terminal needs to roam start when roaming place carries out network registry, in this case, because starting up of terminal can be divided into two processes, before one is SIM card operation and after SIM card operation, and the IMSI switching methods (i.e. step 202b to 206b) that the embodiment of the present invention is provided can be applied to before SIM card operation, can also be applied to after SIM card operation.

It is preferred that, if terminal is roamed in roaming place and started shooting, the limited service that step 202b to 206b registers roaming place can be preferentially performed before the SIM card operation of terminal, and complete the 2nd legal IMSI of roaming place switching, so, with regard to the checking without carrying out IMSI legitimacies to SIM card after the SIM card operation of terminal, the network of roaming place is directly registered according to the 2nd legal IMSI, the speed of roaming place network registry is improved while the available machine time is reduced.

In addition, after execution of step 204b, if the first IMSI that terminal is being used is consistent with the IMSI determined, performing step 208b.

Specifically, in step 208b, if the first IMSI that terminal is being used is consistent with the IMSI determined, the first IMSI that i.e. terminal is being used is legal in roaming place, so, terminal directly can carry out location update operations using the PLMN of the legal roaming place, and complete to register the PLMN of roaming place network registry.
