Problems solved by technology

[0006] 1) Existing dual-mode terminals do not have an obvious tendency to choose 2G or 3G networks, so that the 3G networks cannot be reused;
[0007] 2) In the actual application environment where 2G and 3G networks coexist, there will be various situations. For example, the 2G network does not necessarily support information notification to neighboring cells of other 3G standards, so that the terminal will frequently perform notifications on neighboring cells of 3G standards.

Embodiment Construction

[0027] Hereinafter, the dual-mode terminal and the method for selecting a resident network of the present invention will be described in detail with reference to FIGS. 2 to 10 .

[0028] The dual-mode terminal of the present invention further includes a control and judgment module on the basis of the existing dual-mode terminal. As shown in FIG. 2 , the control and judgment module is set between the access layer module of the first mode and the access layer of the second mode. Between layer modules, it is used to send a message of searching for the first mode cell to the first mode access layer module after power-on, and receive the message of success or failure of camping in the first mode cell sent by the first mode access layer module , when receiving the message of the camping failure sent by the access layer module of the first mode, send a message of searching for the cell of the second mode to the access layer module of the second mode, and receive the message sent by th...

Abstract

A double module terminal and its resident network selecting method are disclosed in the present invention, wherein, the double module terminal resident network selecting method comprises the following steps: a terminal judges whether or not to be able to search the first mode cell and reside successfully, if does, then entering the first mode cell idle mode; otherwise, the terminal judges whether or not be able to search the second mode cell and reside successfully, if does, then entering the second mode cell idle mode, otherwise, the terminal supplies limited service only. The double module terminal and its resident network selecting method of the present invention lead the terminal more likely to reside 3G cell, and avoid redundant electric consumption, so as to improve the system performance.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a dual-mode terminal and a method for selecting a resident network. Background technique [0002] At present, the second generation mobile communication system (2G) is mainly based on the Global System for Mobile Communications (GSM) / General Packet Radio Service (GPRS) standard, that is, the mobile communication system of the GSM / GPRS standard, while the third generation The mobile communication system (3G) consists of a time division synchronous code division multiple access (Time Division-Synchronous CDMA, TD-SCDMA) standard mobile communication system and a wideband code division multiple access (Wide band CDMA, WCDMA) mobile communication system. This standard is the main one, and the mobile communication system of the TD-SCDMA standard is the only 3G mobile communication system that supports Time Division Duplex (TDD) mode. Existing mobile terminals that supp...
