Method, system and device for realizing dual mode dual standby by using dual-mode single-standby terminal

Abstract

The embodiment of the invention discloses a method, a system and a device for realizing dual mode dual standby by using a dual-mode single-standby terminal. The method comprises the following steps that: after being successfully registered in a first network, a mobile terminal determines the paging time of a paging subchannel on the first network; when the mobile terminal initiates registration to a second network, the second network acquires the paging time of a paging subchannel of the second network which is not conflicted with the paging time of the paging subchannel of the first network; and the mobile terminal receives a paging message at the paging time of the paging subchannel of the first network or the paging time of the paging subchannel of the second network. By the method, the system and the device, the conflict of time positions of the paging time of the paging subchannel in two networks when the two networks are operated is avoided, so that the service separate network operation strategy is implemented.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a method, system and device for realizing dual-mode and dual-standby for a dual-mode single-standby terminal. Background technique [0002] A dual-mode single-standby terminal means that the terminal has the ability to access two wireless networks of different standards, but only resides in one of the wireless networks in the idle state. The following is an example of a dual-mode single-standby terminal belonging to TD (Time Division) and GSM (Global System for Mobile Communications) networks. The specific working process includes: [0003] 1. Start the terminal. [0004] 2. The terminal selects a preferred network according to the preset dual-mode working mode (such as automatic dual-mode, TD priority, etc.) to complete the network search and registration process, and enters the Idle (idle) state; in the Idle state, UE (User Equipment, user All connections...

Problems solved by technology

[0007] 5. The terminal judges whether to stay on a network or reselect to another network according to the signal quality of TD and GSM networks, but it can only monitor paging messages from one network at the same time

However, the structure of this kind of terminal is complicated, and two sets of processing systems are required to process the paging of two different networks respectively.

[0009] Since the above-mentioned dual-mode single-standby terminal only resides on one network at a certain time according to the quality of the network signal, it cannot receive paging messages from the two networks at the same time. Therefore, it is impossible to effectively implement the business separation operation strategy of voice and data

In order to solve the above problems, it is necessary to enable the dual-mode single-standby terminal to implement the dual-mode dual-standby function. However, during the working process of the dual-mode single-standby terminal, the network and the terminal use the same seed (such as IMSI) and the same algorithm to determine the paging Sub-channel paging time, in the case of dual-network operation, the time position of the paging sub-channel paging time in the two networks will inevitably conflict
