Abstract

The invention provides a signal transmission method for controlling between a plurality of BSCs and a plurality of MSC servers in the MSC media gateway of the mobile soft switching network. According to the invention, a media gateway includes a plurality of groups of ports, namely divided into a plurality of virtual media gateways logically, wherein the virtual media gateways share the function and the resource of the media gateway, thereby realizing the communication between the plurality of BSCs and the plurality of MSC servers. According to the method and the device of the invention, the resource sharing and the load balance are effectively realized, the number of the mobile management is reduced, the position updating and switching are reduced, the complexity of the network planning is reduced, and the networking is convenient without changing the MSC server and the BSC.

Description

technical field

[0001] The invention relates to a mobile communication network, in particular to a media gateway in a soft-switch-based mobile communication network. Background technique

[0002] For the existing mobile operators, the introduction of softswitch technology into the mobile local network provides an opportunity to solve the problems existing in the 2G switching network. In the most original mobile softswitch network structure, it is assumed that there are two MSC (Mobile Switching Center, Mobile Switching Center) servers, each MSC server is connected to two media gateways (MGW, Media Gateway), and each media gateway is connected to two BSC (Base Station Controller), in real-life scenarios, each MSC server can be connected to multiple media gateways, and each media gateway can be connected to multiple BSCs. Each MSC server covers a different service area. Once one of the MSC servers fails, the BSCs in the service area covered by the MSC server cannot communicat...

Embodiment Construction

[0027] Referring to the accompanying drawings, and referring to the prior art, the specific implementation of the present invention will be described in detail below.

[0028] figure 1 It is a schematic diagram of a network architecture of an N+1 (N=2) backup networking solution based on a mobile softswitch according to the prior art. Those skilled in the art understand that although figure 1 Only two MSC servers are shown in , but there may be N (N>2) MSC servers in a specific application, and at this time, the N+1th MSC server is used as a backup server. Therefore, once figure 1 If one of the N active MSC servers fails, the N+1th MSC server (backup server) can take over the failed active MSC server accordingly and provide services for the BSC. Those skilled in the art can understand this, and will not be described in detail here.
