Communication method and system for a dual-card dual-standby mobile phone

Abstract

The invention discloses a communication method and a communication system for a dual-SIM-dual-standby handset. The method comprises the steps of when an sim1 card is in a normal call state, monitoring a network paging message of an sim2 card in real time; and when the network paging message of the sim2 card is received, sending a paging response message of the sim2 card via radio frequency resources, and building a call connection of the sim2 card. According to the method and the system, the sim2 card can also answer a call when the sim1 card is in the call on the basis of not changing original hardware by further optimizing and improving the call mode of the dual-SIM-dual-standby handset. According to the method and the system, great convenience can be provided for dual-SIM-dual-standby-single-pass users, and hardware cost is not increased.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a communication method and system for a dual-card dual-standby mobile phone. Background technique [0002] Dual-card dual-standby mobile phone means that two subscriber identity module (Subscriber Identity Module, SIM) cards are installed in one terminal at the same time. These two SIM cards can be on standby at the same time. . [0003] Existing dual-card dual-standby mobile phones usually only have one set of baseband and one set of radio frequency resources; during use, there are usually the following two situations: 1. When the sim1 card is transmitting data in the PS domain, the sim2 card can normally answer or Make a call; 2. When the sim1 card is making a call in the CS domain, the sim2 card cannot answer or make a call at this time. [0004] Because when the sim1 card is making a call in the CS domain, the sim1 card completely occupies the radio frequency resource...
