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. Full frequency band search in order to switch from 2G network to 3G network, resulting in waste of power;
[0008] 3) Although the terminal detects that the signal quality of a certain standard cell meets certain requirements, it cannot normally reside in the cell of this standard due to the existence of abnormal interference, so it needs to continuously perform cell reselection, resulting in the terminal being frequently in the Stressful working state wastes its limited energy and shortens standby time

Embodiment Construction

[0027] Below, combined with Figure 2-10 Describe in detail the dual-mode terminal of the present invention and its method for selecting a network to reside on.

[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, such as figure 2 As shown, the control and judgment module is arranged between the access layer module of the first mode and the access layer module of the second mode, and is used to send a message of searching for a cell of the first mode to the access layer module of the first mode after starting up, 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 camping failure sent by the first mode access layer module, access to the second mode The layer module sends a message to search for the second-mode cell, and receives the message of the success or failure of camping...

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 whetheror 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 invention relates to the technical field of communication, in particular to a dual-mode terminal and a method for selecting a network to reside on. 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) is based on the time division synchronous code division multiple access (Time Division-Synchronous CDMA, TD-SCDMA) standard mobile communication system and the wideband code division multiple access (Wide band CDMA, WCDMA) mobile communication system. TD-SCDMA standard mobile communication system is the only 3G mobile communication system that supports Time Division Duplex (TDD) mode. The existing mobile terminals that support the TD-SCDMA standard have better reali...
