Method of updating start-up position area of multi-card mobile terminal with single GSM communication module

Abstract

The present invention relates to a method for updating the start-up location area of ​​a multi-card mobile terminal with a single GSM communication module. After the mobile terminal is started up, it is judged whether a plurality of subscriber identification cards set therein belong to different operators; Multiple subscriber identification cards belong to different operators, then the mobile terminal obtains the location area identification code of each subscriber identification card in turn and performs power-on location area update on the subscriber identification card; if the multiple subscriber identification cards belong to For the same operator, the mobile terminal obtains the location area identification code of one of the subscriber identification cards, and sequentially performs location area update for the plurality of subscriber identification cards according to the location area identification code. The invention supports multiple SIM cards in a mobile terminal with a single GSM communication module to log in to GSM at the same time, can realize simultaneous standby of multiple numbers, has low cost, small size, and also speeds up the update speed of the location area after starting up.

Description

technical field [0001] The present invention relates to the updating of the starting location area of ​​a mobile terminal in GSM, more specifically, a method for updating the starting location area of ​​a multi-card mobile terminal with a single GSM communication module. Background technique [0002] With the rapid development of the mobile communication industry, many users have more than two mobile phone numbers at the same time, corresponding to more than two Subscriber Identity Modules (SIM cards for short). In this case, the user can choose to use more than two mobile phones with each SIM card respectively, but it is very troublesome to carry a plurality of mobile phones with him like this. Therefore, more and more users choose to use mobile phones that support multiple SIM cards, especially 2 SIM cards. [0003] At present, there are two kinds of mobile phones supporting dual SIM cards in the Global System for Mobile Communication (GSM for short): one is a dual SIM mo...

Problems solved by technology

[0004] For a dual-SIM mobile phone with a single GSM communication module, although two SIM cards can be connected, only one SIM card can be in working state at the same time, and the other can be in shutdown state, that is to say, there can only be one number It is in use, that is, dual SIM cards and single standby. Therefore, although this dual SIM card mobile phone can solve the problem of carrying two SIM cards, the two SIM cards cannot be on standby at the same time.

[0005] For a dual-SIM mobile phone with dual GSM communication modules, although two numbers can be in use at the same time, any one can be called in and out, that is, dual-card dual-standby, but two GSM communication modules and two memory cards are required. 1. Each of the two controllers supports a SIM card, which increases the size and cost of the mobile phone
