Referring to Fig. 2; The method second embodiment schematic flow sheet of the selection network that provides for the embodiment of the invention; Need to prove, before method as shown in Figure 2 is implemented, also the network signal power threshold will be set; According to the network signal power that each antenna at this threshold decision terminal receives, whether satisfy the requirement to network signal power when professional of said terminal operating.More concrete, said network signal power threshold can be that user oneself is provided with, and selects the corresponding network signal power of the poorest speech quality of own acceptable as said network signal power threshold; Also can be that terminal manufacturer presets, this terminal can be accepted, and the power that can discern the lowest signal of handling be as said network signal power threshold.
The method idiographic flow of selection network as shown in Figure 2 is following:
At step S200, the terminal receives the signal of each network through each antenna, and detects the signal power of said each network; More concrete, the terminal comprises two antennas at least, and each antenna has each self-corresponding network; For example, there are two antennas at the terminal, lays respectively at the two ends at this terminal; The antenna that is positioned at the upper end can divide multi-address access network (CDMA, Code Division Multiple Access) by correspondence code, and the antenna that is positioned at the lower end can corresponding global system for mobile communications (GSM; Global System for Mobilecommunication), two antennas receive the signal of map network separately respectively.
