Abstract

The invention discloses a GGGC mobile telephone and accomplishment method thereof. The mobile telephone uses a set of GSM communication circuit, an antenna, a single memory, two sets of SIM card interface circuit and an analog switch, and a set of other control circuit. The GSM communication circuit comprising RF circuit and base-band processor; the RF circuit comprises a RF transceiving chip, a RF power amplifier and an antenna switch; wherein, the antenna switch is integrated in a front end module; the base-band processor comprises a GSM signal processor and general embedded CPU; other control circuit comprises a power source power module, a keyboard, an audio circuit and a LCD interface circuit. The GSM mobile terminal of the invention is capable of supporting two SIM cards and standby of the two SIM cards at the same time with only one GSM communication module. The GGGC mobile telephone is smaller volume, which reduces cost of mobile telephone.

Description

technical field [0001] The invention relates to a Global System for Mobile Communications (Global System for Mobile Communications, hereinafter referred to as GSM) communication terminal, in particular to a dual-card dual-standby mobile phone and a SIM card initialization method thereof. Background technique [0002] With the rapid development of personal mobile communications, many users have more than two numbers, corresponding to more than two Subscriber Identity Models (Subscriber Identity Model, hereinafter referred to as SIM cards). In this case, you can choose to use two mobile phones, but it is very troublesome. Therefore, more and more users choose to use GSM mobile phones that support dual SIM cards. [0003] A SIM card is a subscriber identification card, a smart card containing a large-scale integrated circuit, which is used to register important data and information of users. [0004] Currently, there are two technologies that support dual SIM: [0005] 1: Sin...
