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

Abstract

The invention relates to a renewal method for the startup position area of a multi-card mobile terminal with a single GSM communication module, comprising following steps: judging whether a plurality of user identification cards at the mobile terminal belong to different operators or not after the mobile terminal is started up; when the user identification cards belong to different operators, the mobile terminal gets a position area code of each user identification card in sequence and updates the startup position area of the use identification card; when the use identification cards belong to the same operator, the mobile terminal gets the position area identification code of one user identification card, and updates the startup position area of the user identification cards in sequence according to the position area identification code. The invention can support a plurality of SIM cards of the mobile terminal with a single GSM communication module to log on GSM simultaneously, enable simultaneous standby for a plurality of numbers, and speed up the renewal speed of the position area after startup with low cost and small size.

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
