Abstract

A mobile switching center emulation disaster recovery method based on an access position register is disclosed in the present invention. In order to resolve the problem of the hardware processes data to synchronize between two MSCes in prior art with high cost and big difficulty to invent. The present invention comprises the following steps: collocating network information of the main mobile switching center emulation on the standby mobile switching center emulation; when media gateway detects the main mobile switching center emulation generating fault, the standby mobile switching center emulation receives register of the media gateway and maintains its all services and signaling process; the standby mobile switching center emulation receives the gateway signaling sent by the media gateway, and process according to the user dynamic data and collocation. Thus can realize data coherence without synchronizing between the main MSCe and disaster recovery MSCe, and decrease the cost and difficulty for realizing the disaster recovery.

Description

technical field

[0001] The invention relates to a CDMA2000 (Code Division Multiple Access) communication system, in particular to a mobile switching center emulation disaster recovery recovery method based on a visitor location register. Background technique

[0002] After CDMA2000 enters the second stage, control and bearer are required to be separated, and the original MSC (Mobile Switching Center) is split into two network elements: MSCe (Mobile Switching Center Emulation) and MGW (Media Gateway). Generally speaking, one MSCe will control multiple MGWs, which puts forward high requirements on the stability of MSCe. In order to meet this requirement, MSCe can use a disaster recovery mode for networking. That is, the MGW can belong to two or more MSCes at the same time. When working normally, the MGW only interacts with the master MSCe. When the master MSCe fails, the MGW can select one of the other home MSCes as the disaster recovery MSCe according to the algorithm, and ...
