Abstract

The embodiment of the invention discloses a dual SIM card and dual standby communication terminal and a dual SIM card and dual standby communication method under a single baseband and a single radio frequency. The method comprises synchronizing a firth card and a second card to a communication network, recording the network parameters of the first card and the second card, determining whether the card of the communication operation is the first card or the second card before the starting of the communication operation, and carrying out communication operation according to the network parameters of the card which carries out communication operation. The embodiment of the invention can synchronize the two cards so as to ensure the normal proceeding of service communication. The operation is simple and is easy to be managed.

Description

technical field [0001] The present invention relates to the communication field, in particular to a single-baseband, single-radio frequency, dual-card, dual-standby communication terminal and a communication method thereof. Background technique [0002] With the development of society, people communicate more frequently in their work and life. At the same time, people's requirements for communication and communication equipment are getting higher and higher. In order to meet this requirement, mobile phone manufacturers have released a dual-card dual-standby mobile phone. The dual-card dual-standby mobile phone is equipped with dual Subscriber Identity Model (SIM) cards. Dual SIM can be two SIM cards in the same network mode, or two SIM cards in different network modes. [0003] A US patent application published on May 4, 2006, with publication number 2006 / 0095600A1, discloses a dual-mode mobile station. The dual-mode mobile station can support two different mobile commun...
