AI Technical Summary

Problems solved by technology

Due to the limitation of a single radio frequency module, usually the communication terminal cannot meet the two cards to receive BCCH and PCH within the specified period at the same time, resulting in a low connection rate of terminal calls and an increase in the number of network disconnections

Embodiment Construction

[0016] The specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0017] For the convenience of description, the embodiments of the present invention are described by taking its application in Global System For Mobile Communication (GSM) as an example. However, other communication systems in wireless communication, such as Wide Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (Code Division Multiple Access, CDMA2000), Time Division Synchronous Code Division Multiple Access (Time Division - Synchronous Code Division Multiple Access, TD-SCDMA) can support the single baseband single radio frequency dual card dual standby communication terminal and communication method of the present invention.

[0018] FIG. 1 is a schematic structural diagram of a single-baseband, single-radio frequency, dual-card, dual-standby communication terminal according to an embodiment of the present invention. A sin...

Abstract

The invention discloses communication terminal of single baseband single radio frequency and dual-card dual-standby and communication method thereof. The method includes obtaining first and second card network mode information that represents operator information of the first and second card, judging whether the operator information of the first card is the same as that of the second one, and selecting the information network receiving mode according to the judgement. The embodiment of the invention can substantially improve the succeeding rate of the single baseband single radio frequency and dual-card dual-standby communication terminal being called, and greatly decrease dropping probability.

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...
