Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that in the current network implementation, each network element is independent and unique, and the users and functions it manages cannot be replaced by other network elements in the network. Once a serious failure occurs in a certain network element, It cannot be restored in a short period of time, causing a large number of users to be unable to access the network for a long time

Embodiment Construction

[0024] figure 1 It is a flow chart of the disaster recovery method of the mobile softswitch network according to the present invention. Each RNC is connected to two or more (not including two) MSC Servers through the MGW;

[0025] Determine the corresponding relationship between the active MSC Server and other standby MSC Servers, including four schemes: MSC Server 1+1 active-standby scheme, the MSC Server connected to the RNC includes two, one is active, the other is standby, and the standby and Master one-to-one correspondence; MSC ServerN+1 master-backup scheme, there are two MSC Servers connected to the RNC, only one of which is the master MSC Server, and one is the backup, and the backup Servers of all the master MSC Servers are the same MSC Server; the load sharing scheme of MSC Server, the MSC Server connected to the RNC includes two, one is active and the other is standby, and for the standby MSC Server, it is the active MSC Server of other RNCs; the RNC selects the M...

Abstract

The invention discloses a disaster recovery method for a mobile softswitch network, which uses a redundancy mechanism to back up the MSC Server network elements in the PLMN network system, so that the status and function of the network elements in the network are no longer unique, so as to improve the reliability of the network elements. Stability, and the purpose of further improving the stability of the entire network. When a major failure occurs on the MSC Server and it is difficult to recover for a while, the standby MSC Server will take over all users and process user business without interruption to achieve the purpose of disaster recovery.

Description

technical field [0001] The invention relates to mobile communication, in particular to a mobile softswitch network. Background technique [0002] The development of mobile communication technology enables mobile users to realize various services such as call service, short message service, and prepaid service through the operation of different network elements in the core network. [0003] In the PLMN (Public Land Mobile Network, public land mobile network) network, the mobile user is in a certain location area, and the location area is under the jurisdiction of a certain RNC (RadioNetwork Controller, radio access network controller), and the RNC is controlled by a certain MSC Server (Mobile Switching Center Server, mobile switching center server) jurisdiction. When a mobile user needs to perform certain services, it needs to first access the core network through the access network, and then the MSC Server network element in the core network controls the service signaling p...
