[0066] In this embodiment, the radio frequency subsystem A maintains the PS service connection, while the radio frequency subsystem B is initiating a CS call.

[0067] Such as Figure 5 As shown, the communication method of the dual-card dual-pass terminal of the present embodiment includes the following steps:

[0068] Step a1: RF subsystem A maintains the PS service connection;

[0069] Step a2: Determine whether the radio frequency subsystem B initiates a CS call, if yes, turn to step a3, if not, return to step a1;

[0070] Step a3: Obtain the reception level of the radio frequency subsystem B, and determine the transmit power threshold value of the radio frequency subsystem A corresponding to the reception level; specifically, the radio frequency subsystem A can obtain the radio frequency subsystem through the interconnection bus or the application processor The reception level of the CS service of B, and determine the transmit power threshold value of the radio frequenc...

[0080] In this embodiment, radio frequency subsystem A maintains the PS service connection, while radio frequency subsystem B is in a dormant or idle state. In this case, it is necessary to ensure that radio frequency Subsystem B is in a sleep or idle state.

[0081] Such as Figure 6 As shown, the communication method of the dual-card dual-pass terminal of the present embodiment includes the following steps:

[0082] Step b1: RF subsystem A maintains the PS service connection;

[0083] Step b2: Determine whether the radio frequency subsystem B initiates a CS call, if yes, execute the operations as steps a2-a8 in the first embodiment, if not, turn to step b3;

[0084] Step b3: judging whether it is the next DRX (Discontinuous Reception, discontinuous reception) paging cycle, if yes, turn to step b5, if not, turn to step b4;

[0085] Similar to the first embodiment, the radio frequency subsystem A can obtain the reception level of the CS service, and can also obtain the DRX ...

Abstract

The present invention provides a communication method, a communication device for a dual-SIM card-dual-call (DSDC) terminal, and the DSDC terminal. The DSDC terminal includes a first radio frequency subsystem for initiating Packet Switching (PS) service and a second radio frequency subsystem for initiating Circuit Switching (CS) service. The communication method comprises controlling transmission power for the PS service of the first radio frequency subsystem under a predetermined value during a reception timeslot for the CS service of the second radio frequency subsystem. According to the present invention, it is able to overcome the interference between two radio frequency subsystems of the DSDC terminal.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a communication method and device for a dual-card dual-pass terminal and a dual-card dual-pass terminal. Background technique [0002] Usually, different operators will use different wireless access technologies, such a SIM (Subscriber Identity Module, customer identification module) card cannot use another operator's network service without changing the mobile terminal number, so A mobile terminal supporting DSDC (Dual-SIM-Dual-Call, dual-card dual-pass) function is required. [0003] The mobile terminal with DSDC function can support SIM cards of two different operators at the same time and keep the network and standby. On the premise of not switching the mobile terminal number, it can enable the mobile terminal users to use the network services of two different operators at the same time , working in two different network modes at the same time. Unlike Dual-SIM-Dual-Stand...
