Description

Dual-mode SIM card system control device and method

technical field

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

Subscriber Identity Module card (Subscriber Identity Model, referred to as SIM) is also called smart card, subscriber identity card. Almost all mobile communication terminals (for example, 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. In the present invention, for the sake of simplicity, they are collectively referred to as SIM cards, and the SIM cards supporting two systems are referred to as dual-mode SIM cards. As shown in FIG. 1 , it shows a schematic diagram of an architecture between a dual-mode SIM card and a mobile device at this stage.

At present, there are basically two typical situations in the use of dual-mode SIM cards:

Inserted into a single-mode or dual-mode mobile communication terminal of the same type as the dual-mode SIM card; and

Insert it into a dual-mode mobile communication terminal that has the same two modes as the dual-mode SIM card.

It can be seen that since the dual-mode SIM card can support two systems, the use range of the SIM card has been expanded and it is more versatile. In the current situation where multiple wireless mobile communication networks coexist, the dual-mode SIM card can better reflect the superiority. Users can only purchase a dual-mode SIM card to communicate in two different wireless networks.

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 standard of the dual-mode SIM card can be used, and the other part cannot work. If the user wants to use another system of the dual-mode SIM card, he must restart the machine and switch the dual-mode mobile terminal to another system before using it, which makes the user experience worse.

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.
