Embodiment Construction

[0044] The specific implementation manners of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0045] As shown in Figure 1, MSCe1 (mutually active and standby with MSCe2) and MSCe2 (mutually active and standby with MSCe1) are two sets of independently operating equipment, with their own independent MGW (media gateway) and BSC (base station control center). Two MGWs are connected to two MSCes at the same time, the link to the active MSCe is connected, and the link to the backup MSCe is blocked. For MGW1, MSCe1 is the master, and MSCe2 is the backup; for MGW2, MSCe2 is the master, and MSCe1 is the backup; these two MGWs not only serve as media gateways, but also have embedded signaling Transition point), HLR (Home Location Register), SCP (Intelligent Network), BSC and other network elements to send signaling to the active MSCe.

[0046] When both MSCe are working normally, the link between MGW1 and MSCe1 is connect...

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 ...
