Abstract

This invention provides a method and system fir determining route in CDMA A-Flex network. The method comprises: when an information distribution device receives the information of the initiated layer 3 initiated by user, selecting a CN node based on IMSI taken in the information and the corresponding relationship of IMSI and CN node stored in a data backup center, and routing the information to the selected CN node. In addition, this invention further provides a data backup center and an information distribution device. The position update in parts can be reduced through the technical proposal provided by this invention.

Description

technical field

[0001] The invention relates to mobile communication technology, in particular to a method, system and device for determining routing in a code division multiple access (CDMA, Code Division Multiple Access) flexible A-interface (A-Flex) network. Background technique

[0002] In a traditional CDMA network architecture, a mobile switching center (MSC, Mobile SwitchCenter) can be connected to multiple base station controllers (BSC, Base Station Control), and a BSC can only be connected to one MSC. figure 1 A schematic diagram of the connection relationship between the MSC and the BSC under the traditional CDMA network architecture is shown. This 1:N connection relationship between MSC and BSC restricts the flexibility of networking. For example, if an MSC shuts down for upgrade and maintenance or fails, all BSCs connected to the MSC will lose their function, and all users within the coverage of these BSCs will be unable to communicate with circuit services. ...
