Embodiment Construction

[0077] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0078] The gist of the present invention is that whether it is an intra-office channel handover or an inter-office handover, the bearer establishment first notifies the mobile switching center or the main control mobile switching center, and then the mobile switching center or the main control mobile switching center notifies the source base station controller to perform the handover, thus The situation that the handover has been completed but the bearer has not been established will not happen, thus ensuring the channel switching quality; considering extreme cases, if the bearer establishment times out or fails, the handover will be rejected.

[0079] The present invention will be described below through specific examples.

[0080] Such as Image 6 As shown, the intra-office channel switching process based on the IP bearer network is as follows:

[00...

Abstract

This invention discloses a channel switch method including: a source BSC asks for switching channels to MSCe, which informs MGW to set up load with target BSC to inform the MSCe, which informs source BSC and it informs the mobile station for switching and the mobile station switches signals to the channel of the BSC, the switch of inter-office channels includes: the source BSC requires for switching channels to the source MSCe, which informs MGW1 and target MSCe to get ready for setting up load, target MSCe informs MGW2 and target BSC to get ready for setting up load, after setting up the load, MGW1 informs source MSCe, which informs source BSC and BSC informs the mobile station for switch, which switches the signal to the channel of the BSC.

Description

technical field [0001] The present invention relates to the field of packet switching network technology and next generation network (NGN, NextGeneration Networks) technology field, in particular to a channel switching method. Background technique [0002] Such as figure 1 As shown, in the traditional circuit domain structure, MSC (Mobile Switching Center, mobile switching center) and BSC (Base Station Controller, base station controller) are directly connected by TDM (Time Division Multiplex, time division multiplexing) circuit to bear the voice path. Such as figure 2 As shown, after the softswitch structure is adopted, the control and bearer are separated, and the MSC is divided into two parts: MSCe (MobileSwitching Center, mobile switching center) and MGW (Media Gateway, media gateway). on MGW. After the A interface (the interface between the BSC and the MSC) bears the voice path and turns it into IP, the original voice carried by TDM is transmitted through the IP bea...
