Problems solved by technology

[0005] The networking scheme in the Gb-Flex protocol proposed by 3GPP requires all BSCs in the existing network to support the new Gb-Flex standard before it can be implemented. However, almost all BSCs in the current network cannot support this technology, so the Gb-Flex protocol must be implemented In the networking scheme, it is necessary to upgrade the network, including the upgrade of all BSCs
Because the PCU is a functional entity set in the BSC, all PCUs need to be upgraded, which will result in huge work costs and workload. Therefore, the networking scheme in the Gb-Flex protocol is adopted to improve the communication network. reliability is not feasible

Embodiment Construction

[0017] The embodiment of the present invention provides a SGSN backup method, which can improve the reliability of the communication network under the condition of minor changes to the existing network.

[0018] The embodiment of the present invention provides an "N+1" backup solution. The "N+1" concept of communication equipment generally refers to N primary devices and one backup device in common. When a primary device fails, the backup device can immediately take over the business. Of course, N can also be 1. The backup disaster recovery scheme of the embodiment of the present invention has no new functional requirements for the BSC equipment and the transmission network used in the current network. In the solution of the embodiment of the present invention, a backup SGSN is used to provide backup functions for the services of N active SGSNs, and the standby SGSN can automatically detect the failure of the active SGSN, and can take over immediately when it detects that the...

Abstract

The embodiment of the invention discloses an SGSN backup method, comprising that the supporting point SGSN of a standby service GPRS is linked with a packet control unit PCU, and the configuration data of a primary SCSN is synchronized through a channel arranged between the primary SCSN; when a standby SGSN tests that the primary SGSN is in failure, a business processing is done to the business data transmitted by the PCU, according to synchronous configuration data; correspondingly, the embodiment of the invention provides a communication system and communication equipment, and the technical proposal provided by the embodiment of the invention can improve the reliability of the communication network with little alteration towards the present networks.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a SGSN backup method, communication system and communication equipment. Background technique [0002] The GPRS (General Packet Radio Service, general data packet service) service is a wireless packet data service provided on the basis of the GSM (Global System for Mobile Communications, Global System for Mobile Communications) service, which is currently widely used around the world. At present, the networking modes of GPRS equipment running on the existing network only support one BSC (Base Station Controller, Base Station Controller) equipment to access the only serving GPRS support node SGSN, and this SGSN provides services for the BSC. Once the SGSN that provides services for this BSC fails, the services of all terminal MS users connected to the BSC will be interrupted, which will cause a large number of users to be unable to use the network normally, seriously affectin...
