Problems solved by technology

The main disadvantage of the above solution is that since each MSC needs to be provided with a backup, for the operator, the 1+1 backup to deal with such a small probability event as a severe natural disaster is a huge waste of investment and communication resources ; Simultaneously, because the current MSC can only support the MSC of the same manufacturer as oneself to carry out the backup, can't carry out the backup to the heterogeneous model, also brings trouble to the backup in reality; Processing load, its processing capacity is lower than that of the normal switch without backup

Embodiment Construction

[0022] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0023] The backup method of MSC in the present invention can realize the backup of N+1 of MSC, that is, one backup MSC backs up N MSCs in the local network, and when one or more MSCs break down, the backup MSC can quickly take over their business. In order to identify its unique position in the network, each MSC must have its own signaling point code (OPC) on the A interface side and the network side. In my country's GSM standard, the A interface side uses 14 bits, signaling The point attribute is the domestic spare signaling point code. For MSC equipment that does not use the multi-signaling point technology, the MSC has only one unique signaling point code on both the A interface side and the network side. For MSC equipment using multi-signaling point technology, MSC can virtualize multiple signaling points on the A interface side or network side, and each...

Abstract

This invention discloses a backup method fo r a mobile exchange center including: applying 14 bit A interface signaling transfer points technology to allocate for them; judging if MCS at the fault stage and converting the master and backup MSC which replaces service of the fault MSC; judging if the fault has resumed mormal to deactivate MSC response MTP, signaling atate at sccp layer and relay toinform the resumed MSC to switch to normal state, which can support one-to-many MSC backup way to backup all MSC of homenet with only one backup MSC, no need to machine type nor influence to other network elements.

Description

technical field [0001] The invention relates to a backup method in mobile switching in a mobile communication system. Background technique [0002] Due to the uncertainty of natural disasters, the impact on the mobile communication system is also random, so it is necessary to back up the mobile switching center (MSC) in the mobile communication system, so that when the MSC equipment in the system is due to severe natural disasters or other Reasons, such as earthquakes, floods, equipment failures, power supply damage, etc. have caused functional paralysis, and when it cannot be repaired in a short time, its functions will be quickly taken over by another backup MSC device. The currently used MSC backup method is mainly a one-to-one hot backup solution, which provides each operating MSC with a backup MSC, and the base station control center (BSC) is connected to the active MSC through a relay, but When the MSC fails, cut over the trunk connection between the BSC and the activ...
