Embodiment Construction

[0013] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0014] Fig. 1 is the main flow chart of the present invention, mobile terminal is in the situation of double standby of TD-SCDMA and GSM two kinds of standards, when a kind of standard module produces the call event, set the relevant parameter of calling, shut down another kind of non-calling Then continue the normal call process; at the end of the call, turn on the radio frequency of the module that has been turned off, and return to the standby state before the call.

[0015] Figure 2 is a detailed flowchart of an embodiment of the present invention. The whole process can be divided into four parts:

[0016] 1. A TD-SCDMA and GSM dual-mode mobile terminal starts to make a call, and turns off the radio frequency of the system that is not calling.

[0017] In the case of dual standby, whether it is a dual-mode mobile terminal callin...

Abstract

Under condition of dual stand by in TD-SCDMA and GSM two systems, when calling event occurs at module in one system, first, mobile terminal closes down radio frequency of module in the system, where no calling occurs; then, carries out normal call flow. When the call is eliminated, the method turns on the closed radio frequency of the module in the system so as to get back to stand by state. In calling time, the invention only runs one system, thus, signal interference will not occur so as to guarantee quality of call.

Description

technical field [0001] The invention relates to a TD-SCDMA and GSM dual-mode mobile terminal, in particular to a call of a TD-SCDMA and GSM dual-mode mobile terminal. Background technique [0002] According to the calculation of the mature commercial use of China's 3G environment in 2008, China's 3G licenses are expected to be officially issued in the third and fourth quarters of 2006, and TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, hereinafter referred to as TD-SCDMA) is very likely to become the first 3G license issued. TD-SCDMA network has to face the problem of insufficient network coverage in the initial stage of construction. If this practical problem cannot be solved, it will greatly affect the development of TD-SCDMA users, and then affect the development of TD-SCDMA in China and the world . To solve this problem, the best solution at present is nothing more than using other networks to supplement the TD-SCDMA network. The GSM network just me...
