Embodiment Construction
[0044] The present invention has the method for updating the start-up location area of ββa multi-card mobile terminal with a single GSM communication module, and supports multiple SIM cards in a mobile terminal with a single GSM communication module to log in to GSM at the same time, that is, to be in a standby state at the same time. In this embodiment, as figure 1As shown, a dual-card mobile terminal supporting a single GSM communication module is taken as an example. The dual-card mobile terminal includes a GSM communication module, a memory (such as Spanion FLASH), a controller (such as PM+VCO529), and a first SIM card and a second SIM card, wherein the GSM communication module includes an antenna, a radio frequency circuit (such as SILAB 4210+FMD3198) and a baseband processor (such as SPREADTRUM 6600D), and are respectively connected to the first SIM card and the second SIM card through an analog switch to control the switching of the first SIM card and the second SIM card...

Abstract
The present invention relates to a method for updating the start-up location area of ββa 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 ββa mobile terminal in GSM, more specifically, a method for updating the starting location area of ββa 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...
