Problems solved by technology

[0014]However, in some scenarios in the actual application process, a terminal device that supports multi-network access does not support the reporting of measurement messages containing information about another network cell function, or one network cannot resolve the cell information of another network, which makes the above handover process impossible, that is, in some scenarios, the network handover function cannot be realized

specific Embodiment 2

[0099] In this implementation solution, specifically, the RNC initiates a call process to the switched target network, so as to realize the switching operation between the two networks.

[0100] The specific process of this realization scheme is as follows: Figure 5 with Image 6 shown, including the following steps:

[0101] Step 21: RNC or terminal device initiates a handover request to TD-MSC;

[0102] After the terminal equipment moves to the fringe area of ​​the TD network coverage area, the RNC or the terminal equipment detects that the terminal equipment is about to leave the TD network coverage area and enter the GSM network coverage area, then the RNC or the terminal equipment initiates a handover to the TD-MSC ask;

[0103] Step 22: TD-MSC initiates a call to GSM-MSC after receiving the switching request, and the called number is the number of the terminal device in the GSM network;

[0104] Step 23: After receiving the call initiated by the TD-MSC, the GSM netw...

Abstract

The method comprises: during a call process, if a terminal device needs to be switched from an area covered by a first network to an area covered by a second network, it can directly initiates a call to the opposite end in order to establish voice channel; the call of the terminal is switched to said voice terminal. By the invention, even the terminal device not supporting the function of reporting the measuring message, it can also realize the network switch function.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a network switching technology. Background technique [0002] In a wireless communication system, a terminal device needs to be connected to a base station cell of a wireless network through a wireless signal in order to make a corresponding call. [0003] When a terminal device moves from a certain cell range to another cell, in order to keep the call uninterrupted, the connection between the terminal device and the base station cell needs to be handed over to another base station cell. [0004] With the development of communication technology, terminal equipment supporting different network access functions may need to switch from the base station cell of one network to the base station cell of another network to communicate in the process of moving, that is, it needs to be in different networks Realize the corresponding network switching function. [0005] At present,...
