Embodiment Construction

[0034] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0035] Fig. 1 is a flowchart of an automatic network selection method according to the present invention. As shown in Figure 1, the automatic network selection method of the 2G network and the 3G network dual-mode mobile terminal includes:

[0036] Step S102, when the dual-mode mobile terminal resides in the 2G network and is in the idle mode, periodically search whether there is a 3G network, and measure the relevant information of the searched 3G network if the 3G network is found; and

[0037] Step S104, judging whether the measured information about the 3G network satisfies a predetermined threshold, and determining whether to start network mode switching accord...

Abstract

The invention provides a method and a device for automatically selecting network for a dual mode mobile terminal from 2G network and 3G network. The method for automatically selecting network includes: step 1, periodically searching whether a 3G network is present when the dual mode terminal is retained in a 2G network and in idle state, and measuring related information of the 3G network if a 3G network is determined to be present; and step 2, judging whether the related information measured of the 3G network satisfies a predetermined gate limit, and determining if the network mode should be switched or not based on the judging result. Thus, with the invention, the problem that automatic selection on network cannot be performed when a user accesses from a GSM network to a TD-SCDMA network is solved.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to an automatic network selection method and an automatic network selection device for a 2G network and a 3G network dual-mode mobile terminal. Background technique [0002] With the continuous maturity of the third-generation mobile communication system, the continuous acceleration of the commercial process, and the gradual promotion and application in the world, more and more users will start to use the richer and more personalized new services brought by the 3G network However, due to the comprehensiveness and integrity of the current 2G network coverage, 2G and 3G networks will coexist for a period of time, so multi-mode mobile terminals that support multiple network standards will emerge as the times require. [0003] TD-SCDMA (Time Division-Synchronous Code Division Multiple Access, Time Division-Synchronous Code Division Multiple Access) and GSM (Global System for Mobile...
