Abstract

The invention provides a dual-card dual-standby communication terminal and a dual-card control method thereof so as to solve a problem that a traditional dual-card dual-standby communication terminal cannot automatically control use conditions of a master card and a sub-card. The method comprises the steps of reading identification information of intelligent card chips in two card slots in the process of power-on detection of the dual-card dual-standby communication terminal; comparing the read identification information of the intelligent card chips with identification information stored in the dual-card dual-standby communication terminal to determine the master card and the sub-card; and judging the status of the master card and the sub-card, and terminating use of the sub-card when the master card does not exist or is abnormal in use. The dual-card dual-standby communication terminal and the dual-card control method thereof automatically control using permissions of the dual cards in the dual-card dual-standby communication terminal under the condition of ensuring that interference of other external conditions are not required, thereby simplifying a control method of the master card and the sub-card, and improving the utilization rate of network resources.

Description

technical field [0001] The present application relates to the technical field of mobile communication, in particular to a dual-card dual-standby communication terminal and a dual-card control method thereof. Background technique [0002] With the rapid development of communication technology, users' requirements for the functions of communication terminals (such as mobile phones) are also constantly increasing. In recent years, dual-card dual-standby mobile phones have become more and more popular among consumers. [0003] Dual-card dual-standby mobile phone refers to a mobile phone that can be loaded with two SIM (Subscriber Identity Model, customer identification module) cards, USIM (Universal Subscriber Identity Module, global customer identification module) cards or UIM (User Identity Model, user identification module) at the same time card, and both cards are in standby mode. [0004] The common dual-card dual-standby mobile phones currently on the market have no restr...
