Abstract

The invention discloses a multimode terminal and a method for eliminating the return current influence. In the method, when a primary wireless module of the multimode terminal detects that a secondary wireless module is switched from an on state to an off state, the control port of the secondary wireless module is set in off state. The multimode terminal comprises the primary wireless module and at least one secondary wireless module. The primary wireless module is connected with the secondary wireless module via the control port, wherein the primary wireless module is used to detect the state of the secondary wireless module and configures the control port of the secondary wireless module in off state when detecting that the secondary wireless module is switched from the on state to the off state. With the inventive multimode terminal and the method, when the secondary wireless module in the multimode terminal is switched from the on state to the off state, the primary wireless module can configure the control port of the secondary wireless module in off state, so that the electrical level of the control port is in determined state to eliminate the influence of the return currenton the multimode terminal.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a multi-mode terminal and method for eliminating the influence of current backflow. Background technique [0002] Most of the current multi-mode terminals are a plurality of wireless modules of the same standard or multiple standards, combined together, and in order to save standby current, a sleep wake-up is used to control the communication between multiple wireless modules. However, this design requires the hardware connection ports of multiple wireless modules to cooperate to control the communication between wireless modules, and after the user switches modes and chooses single-mode standby or multi-mode standby, the hardware connection port of the wireless module is used to control the shutdown or Turn on one or more of the wireless modules. [0003] In the multi-mode terminal, the main wireless module plays the main control role, completes the main man-machine interfac...
