Abstract

The invention discloses a communication method and a mobile terminal which are used for solving a problem that two SIM cards of a CDMA (Code Division Multiple Access) type cannot intelligently realize dual SIM dual standby. The communication method disclosed by the embodiment of the invention comprises the steps that the mobile terminal configures a first SIM card to correspond to a master protocol stack and configures a second SIM card to correspond to a slave protocol stack, wherein the first SIM card and the second SIM card are SIM card of a CDMA network type; the mobile terminal register a network through the first SIM card; the mobile terminal stores state information of the first SIM card after the network is registered; the mobile terminal updates a display interface of the mobile terminal by using the state information of the first SIM card; the mobile terminal switches the first SIM card corresponding to the master protocol stack into the second SIM card; the mobile terminal registers a network through the second SIM card; the mobile terminal stores state information of the second SIM card after the network is registered; and the mobile terminal updates the display interface of the mobile terminal by using the state information of the second SIM card.

Description

technical field [0001] The present invention relates to the communication field, in particular to a communication method and a mobile terminal. Background technique [0002] In existing mobile communication systems, CDMA communication systems based on CDMA (Code Division Multiple Access, Code Division Multiple Access) technology still occupy an important position. In the era of sharply increasing communication demand, people's demand for dual-card dual-standby functions of mobile terminals is also increasing. [0003] In the prior art, the SIM (Subscriber Identity Module) card of the CDMA network standard can only correspond to the main protocol stack, and there is only one main protocol stack in the Modem (modem) software of the mobile terminal, and the existing mobile terminal can only support one A SIM of CDMA network standard and a SIM of other non-CDMA standard to realize the dual standby function. [0004] In the prior art, for a mobile terminal with only one Modem a...
