In the example 4, there is a GSM mode in both the first communication module and the second communication module, so the first communication module can share the GSM physical layer of the second communication module (as shown in FIG. 9), or the first communication module The physical layer can share the GSM RF module in the physical layer of the second communication module (as shown in Figure 10) to reduce cost.

With the above technical solution of the present invention, the terminal can simultaneously communicate with the plurality of networks supported by the terminal, and set the service carried out by each network by using the service allocation rule, which helps each network supported by the terminal to be enabled. Give full play to their respective strengths and provide corresponding services for the terminal (for example, the terminal can realize voice service through 2G network, and realize data service by means of 3G network, so as to obtain high-quality service by using the respective characteristics of 2G and 3G networks), avoiding a single network When all the services are provided for the terminal, the problem of all the service requirements cannot be balanced due to the limitation of the single network itself, and the user experience is improved, which is conducive to the integration and development of multiple communication modes; and the terminal does not need to change the user identification information (single SIM card), thereby reducing the amount of user operations.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, equivalents, improvements, etc., which are included in the spirit and scope of the present invention, should be included in the present invention. Within the scope of protection.
