For enabling above-mentioned purpose of the present invention, feature and advantage more become apparent, and are described in detail specific embodiments of the invention below in conjunction with accompanying drawing.
Take communication terminal as the mobile telephone with multiple cards mobile phones of more than two or two Subscriber Identity Modules (support), client be car phone is example, when cellphone subscriber uses mobile phone in automobile, because vehicle body has attenuation to mobile phone signal, when mobile phone therefore can be caused to use in car, speech quality is poor, data service rate is low.And mobile phone mostly in the market is smart mobile phone, power consumption can be made when received signal quality is poor to increase, further shorten stand-by time.But the built-in car phone of automobile itself is positioned at automobile external due to its antenna, and therefore the quality of its Received signal strength will be much better than the mobile phone being in automotive interior.At this moment, if mobile phone is by the external antenna connection mobile network of car phone, just greatly can improves the received signal quality of mobile phone, reduce the power consumption of mobile phone.
Car phone can think a complete mobile phone, be just fixed on automotive interior, and the antenna of its radio frequency unit has extended to automobile external.It can pass through bluetooth (BT, BlueTooth) wireless technology is connected on the mobile telephone with multiple cards in automobile, user can not change user identity identification (SIM, Subscriber Identity Module) when blocking, easily arbitrary SIM card is switched to contextual model in car (namely connecting the pattern of mobile network by the external antenna of car phone).Between car phone and mobile telephone with multiple cards, bluetooth remote access connection realizes based on bluetooth SIM remote access protocol (SAP, SIM Access Profile).When car phone by bluetooth wireless interface to mobile telephone with multiple cards in arbitrary SIM card carry out remote access time, mobile telephone with multiple cards is the server that SAP access connects, what realize is the function of SIM card card reader, the relevant information of the SIM card read is sent to the client of SAP access connection by it by bluetooth wireless interface, namely on car phone.Wherein, establish bluetooth remote in mobile telephone with multiple cards to access the SIM card be connected be defined as accessed SIM card with car phone.
Need explanation, in embodiment of the present invention, alleged SIM card is the general designation of various subscriber identification module, it can also represent Global Subscriber identification card (USIM, Universal Subscriber Identity Module) or the subscriber identification module of the other types such as Subscriber Identity Module (UIM, User Identity Module).
Embodiment one
Fig. 1 is that the mobile phone of the embodiment of the present invention one sets up with car phone the schematic flow sheet that bluetooth remote accesses the method be connected, and comprising:
Step S11: user opens the remote access function of mobile phone.The remote access function of mobile phone generally can not be set to automatic unlatching, needs user manually opened during use, and user can find and arrange menu accordingly in function menu, and selects to open.
Step S12: after mobile phone receives remote access startup request, search remote access service, if search, adds to remote access service in current service record, and the RAS function Activated Phone.After user selects the remote access function of starting hand-set in step s 11, mobile phone will receive remote access and start request, and at this moment mobile phone will search for the related protocol of the remote access (under referred to as remote access) that whether there is subscriber identification module in its protocol stack.If the remote access function of SIM card supported by mobile phone, then the related service of the remote access protocol searched is added in current service record, and the remote access server capability Activated Phone.In technical solution of the present invention, realize connecting by Bluetooth technology between the SIM card of mobile phone and car phone, if only from the angle of transfer of data, the server that mobile phone can be connected as bluetooth with car phone, but in technical solution of the present invention, the object that bluetooth connects is to make SIM card carry out data interaction by car phone and mobile network, and these data final process remains and completes in mobile phone, therefore mobile phone is only the side providing service in the bluetooth connection of technical solution of the present invention, therefore can determine that mobile phone is the server in the bluetooth remote access connection of technical solution of the present invention, car phone is then client.
Step S13: obtain the received signal quality that community, each SIM card place is corresponding, and SIM card best for received signal quality is defined as accessed SIM card.Concerning the mobile phone in the present embodiment is multi-mold multi-card mobile phone, huge difference may be there is in the performance of the community of the mobile network at each SIM card place of synchronization, such as the double-mode double-card mobile phone supporting GSM/WCDMA, at synchronization, the MPS process situation of GSM network may be better than the community of WCDMA network, at this moment the SIM card 2 corresponding to WCDMA network is just better than corresponding to the received signal quality that the community, SIM card 1 place of GSM network is corresponding, if at this moment user couple and car phone set up bluetooth remote when accessing the SIM card that is connected without particular/special requirement, mobile phone just can automatically using SIM card 1 as accessed SIM card.During concrete enforcement, due to heterogeneous networks pattern to received signal quality have respective definition, in order to simplify judgement flow process, can directly using the intensity of Received signal strength as criterion, the power of signal that namely which SIM card receives greatly just thinks that its quality is good.In other embodiments, when mobile phone is single mode mobile telephone with multiple cards, because each SIM card is all in identical community, then the minute differences between the Received signal strength can ignoring each SIM card, arbitrarily selects a SIM card.
