Abstract

The invention reveals a method for controlling double-CDMA user identification module for CDMA / GSM double-mode mobile phone. Without changing the hardware of CDMA / GSM double-mode mobile phone, the invention uses a CDMA control module to operate a first CDMA user identification module or to found a mutually- connected GSM asynchronous receiver and driver module and a driver module of UIM and SIM on a GSM control module. The GSM asynchronous receiver and driver module is communicated with the drive layer of the CDMA device of the CDMA control module by universal asynchronous receiver transmitter (UART) so that the CDMA control module controls a second CDMA user identification module connected with the driver module of UIM and SIM; double-CDMA user identification module can be controlled in CDMA / GSM double-mode mobile phone; and then, the needs of businessmen and individuation lovers can be satisfied.

Description

technical field [0001] The present invention relates to a method for controlling dual CDMA subscriber identification modules, and in particular to a method for controlling dual CDMA subscriber identification modules for a CDMA and GSM dual-mode mobile phone. Background technique [0002] At present, wireless communication technology has developed many specifications and standards. Common wireless communication systems include GSM (Global System for Mobile Communication, Global System for Mobile Communication), CDMA (Code Division Multiple Access, code division multiple task system), PHS (Personal Handy-phone System, In order to meet the needs of users' mobile phones to switch between different standard and standard systems, various mobile phone communication companies have developed mobile phones with dual-mode systems. For example, there are CDMA and GSM systems in a mobile phone. is one of the representatives. [0003] Please refer to figure 1 , which is a conventional C...
