The dual card refers to a mobile terminal having two card slots, and capable of installing two USIM (universal subscriber identity Module)/SIM (subscriber identity Module) cards, where each USIM/SIM card may support one or more network systems, and the two USIM/SIM cards may belong to the same operator or different operators. The dual standby function means that when two USIM/SIM cards support different network systems, the mobile terminal supports the two USIM/SIM cards to register successfully on two networks respectively, and simultaneously stands by; when the two USIM/SIM cards support the same network system, the mobile terminal supports the two USIM/SIM cards to successfully register on the same network and simultaneously stand by.
For a dual-card dual-standby mobile terminal, when one card is a 4G multi-mode card and the other card is a 3G/2G card, if the 4G multi-mode card selects a CSFB (circuit switched FallBack) technology to implement voice call, the 4G multi-mode card first needs to implement a joint attachment procedure; meanwhile, the CSFB call includes a CSFB fallback phase, a 3G/2G side RRC (radio resource control) access phase, and a call setup phase. The CSFB fallback stage comprises inter-system cell measurement, measurement report reporting and the like; the 3G/2G side RRC access phase comprises synchronization, system message reading, RRC establishment and the like. Due to the fact that the CSFB call process is complex, call setup time is long, when the dual-card dual-standby mobile terminal does not need to use the 4G multi-mode card for data traffic service, the 4G multi-mode card also needs to be opened to prevent missed calls, and therefore the dual-card dual-standby mobile terminal is high in electricity consumption and poor in user experience.
