Terminal and communication channel switching method

Abstract

The invention provides a terminal and a communication channel switching method. The terminal comprises a switching module, wherein the switching module is used for receiving an identification code from external equipment of the terminal, selecting a communication channel between the terminal and the external equipment according to the received identification code, and switching to the selected communication channel. In the technical scheme, the corresponding communication channels can be automatically switched according to different identification codes, for example, when an earphone with different identification codes accesses the terminal, different network modules are switched by using the switching module.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a terminal and a communication channel switching method. Background technique [0002] The mobile phones we use now usually have tail plugs, which are used to connect external devices so that the mobile phone can communicate with external devices. There is a toggle switch for the tail plug connection, through which the data transmission between the external device and the AP and different modules can be realized. The principle is as follows: figure 1 shown. [0003] When the tail plug 104 needs to communicate with the internal AP108 or module, through manual operation control, send an instruction to the AP108, and then the AP108 sends a control signal to control the switch 102 to switch the data channel and connect to the AP108 or other modules. The AP here refers to the application processor in the mobile phone. [0004] The manual operation control here sends inst...

Problems solved by technology

[0005] The disadvantages of the above solution are: 1. Regardless of whether the AP system is not started or after it is started, if you want to switch the control switch 102, you need to actively and manually control it, which is not intelligent enough, and sometimes the operation will be slightly cumbersome

2. When the AP is not started, switching the switch 102 in the way of combination keys will be limited by the number of external keys, which has certain disadvantages. For example, there are N communication modules in a multi-mode mobile phone. If you want to switch between N channels To switch, the various key combinations may not be enough, so that it is impossible to switch between multiple module channels
