Embodiment Construction

[0018] An example implementation of implementing service distribution and system expansion using the method provided by the present invention in a 3G system will be described below with reference to the accompanying drawings.

[0019] 1) The system currently has 3 modules to handle business, they are module 0, module 1 and module 2.

[0020] 2) Create a query table with 16 entries, such as figure 1 As shown in the initialization, there are 5 grids pointing to module 0, 5 grids pointing to module 1, and 6 grids pointing to module 2 in the table, and each module shares business according to 5:5:6.

[0021] 3) When a service arrives and the last 4 bits of the TEID it carries are 9, the lookup table gets 1, which is assigned to module 1 for processing, such as figure 1 .

[0022] 4) If other business arrives, handle it in the same way as 3).

[0023] 5) At this time, expand the capacity and add module 3, according to figure 2 Adjust the query table, change item 4, item 9, ite...

Abstract

The user's key assignment method supporting communication system nucleus network includes the following steps: establishing one enough large query table of 2n items based on the estimated ultimate module number and marking the modules, with the each item of the query table recording only the number of each module; configuring the query table to make the module number of each module appear in the same or basically the same times, regulating the query table while altering the item as less as possible and looking for the business releated to the tunnel terminal mark in all the modules before transferring it to new or other module in case of altering the on-line capacity or module number of the nucleus network; and looking for corresponding item and the item recorded module number based on the last n bit value of the user key number entering the business and assigning the business to the module corresponding to the module number for processing.

Description

technical field [0001] The present invention relates to a user key distribution method of a communication system core network, in particular to a user key distribution method in switching devices SGSN (Serving GPRS Support Node) and GGSN (GatewayGPRS Support Node) of a third-generation mobile communication (3G) network . Background technique [0002] Network and communication is one of the hottest and fastest-growing fields today. In order to cope with the increasingly busy information flow, the processing capacity of communication network equipment has been continuously improved, and various large-capacity node devices have emerged continuously. The structure of single CPU and centralized processing It is increasingly unable to meet the needs of the market. Today, manufacturers generally adopt distributed processing technology to disperse the processing of communication services on multiple modules and multiple CPUs. The first is to break through the current technical limi...
