Network switching method and corresponding mobile terminal

Abstract

The invention discloses a network switching method and a corresponding mobile terminal. The network switching method comprises the following steps that: the mobile terminal is kept on a first network for standby; the mobile terminal receives data service commands sent by users; the mobile terminal detects the signal intensity of a second network, and if the signal intensity of the second network reaches a threshold value, the mobile terminal is switched to the second network from the first network; the mobile terminal finishes a data service through the second network; and the mobile terminalis switched from the second network to the first network for standby. The mobile terminal provided by the invention can implement the method. By implementing the network switching method and the corresponding mobile terminal of the invention, the problems that in areas with poor 3G network coverage, the mobile terminal is frequently switched between a 2G network and a 3G network to cause power consumption increase for the mobile terminal and a transient call failure is easy to happen during switching can be solved.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a network switching method and a corresponding mobile terminal. Background technique [0002] It has been more than half a year since the issuance of 3G licenses. With the start of WCDMA trial commercial use of China Unicom, the last of the three major operators, my country will also enter the 3G era in an all-round way. Judging from the current network coverage situation, the difficulty of building a CDMA 1X EV-DO network is relatively small. Since China Telecom has already deployed CDMA 1X base stations in most areas, the EV-DO carrier frequency for 3G services , only need to increase the corresponding carrier frequency, but the coverage of CDMA 1X EV-DO is far below that of 2G network. As for TD and WCDMA, because they are brand new networks, new sites need to be built, and due to frequency band issues, most of the original indoor distribution systems are not...
