Dual-mode SIM card control device and method

Abstract

This invention discloses one double mode SIM card progress control device and its method, wherein, the device comprises the following parts: order identification module to identify the user terminal mode according to the operations and to send the results to the control module; progress control module to set SIM card mode in user terminal as first and second modes and to get double mode SIM card at double mode memory module and to send the needed data to double model wait user terminal; public data memory module to extract first and second mode public data to store public data.

Description

technical field [0001] The present invention relates to the communication field, and more particularly relates to a dual-mode SIM card system control device and method. Background technique [0002] A Subscriber Identity Model (SIM for short) is also called a smart card or a subscriber identity card. Almost all mobile communication terminals (such as mobile phones, wireless network cards, wireless modules, etc.) must be equipped with this card before they can be used. Such mobile communication terminals are usually called "User Equipment" (UE for short). According to different wireless mobile communication standards, there are UEs of different standards, and the names of subscriber identity modules of different standards are also slightly different. Among them, the subscriber identity module of GSM and CDMA standard is called SIM, the subscriber identity module of TD-SCDMA and WCDMA standard is called USIM, and the subscriber identity module of PHS standard is called PIM. ...

Problems solved by technology

[0007] However, there are still some problems in the practical application of dual-mode SIM cards: if the dual-mode SIM card is only used in single-mode mobile terminals, it is no different from the single-mode SIM card, which means that 50% of dual-mode SIM card resources are wasted ;The dual-mode SIM card is inserted into the dual-mode mobile terminal. Due to the limitation of the dual-mode SIM card reading and writing mechanism, the dual-mode mobile terminal cannot operate the two modes supported by the dual-mode SIM card at the same time, and the dual-mode terminal works in a standby state in one mode. , only the part of the same format of the dual-mode SIM card can be used, and the other part cannot work

If the user wants to use another mode of the dual-mode SIM card, he must restart the machine and switch the dual-mode mobile terminal to another mode before using it, which makes the user experience worse.

[0008] In short, the advantages of dual-mode SIM cards have not been fully utilized in actual use, and the limitation that the two systems cannot be operated at the same time also brings disadvantages to the development of dual-mode dual-standby terminals
