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. ...

Examples

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0035] It can be seen from the description of the background technology that in the existing CDMA A-Flex network, the method of determining the message route according to the routing information configured on the BSC may easily cause the change of the user service MSC, resulting in an increase in the number of inter-office location updates.

[0036] In order to overcome the above problems, the embodiment of the present invention provides a method for determining routing in a CDMA A-Flex network, including: setting up a data backup center, storing the corresponding relationship between the user's IMSI and the MSC in the data backup center; After receiving the initial layer 3 message, an MSC is selected according to the IMSI carried in the message and the ...
