Abstract

Through maintaining information of route state of tunnel protocol GTP in general packet radio service (GPRS) between SGSN and other GPRS supported nodes GSN, when user initiates activation of flow (INTER-SGSN RAU) for route area updating between flow of packet data protocol (PDP) and SGSN, the method uses maintained information of route state to carry out operation of filtering GSN, which initiating flows try to use, and to deletes part of defective GSN. Thus, the method initiates flows to current available GSN directly. Filtering out part of defective GSN, the invention raises success ratio of flow.

Description

technical field

[0001] The invention relates to a flow processing method in a service support node (SGSN) in a general packet radio service (GPRS) network, in particular to a method for improving the flow success rate by filtering faulty GPRS support nodes (GSN) in the SGSN in the GPRS network. Background technique

[0002] At present, the GPRS network and Wideband Code Division Multiple Access (WCDMA) network used for high-speed Internet access are developing rapidly, especially the GPRS network, which has been commercially used on a large scale in many countries and regions. Its network architecture is as follows: figure 1 shown. From figure 1 It can be seen that the GPRS network users establish connections with the packet data protocol (PDP) network through the SGSN and the GPRS Gateway Support Node (GGSN).

[0003] In the GPRS / WCDMA application scenario, after the mobile phone user activates the PDP successfully, the user can browse the web, send EMAIL, send or receive...

Embodiment Construction

[0029] 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.

[0030] In the present invention, the SGSN needs to maintain the GTP path information table between the SGSN and other GSNs, which is realized in the following manner:

[0031] At any time, the SGSN keeps a GTP path information table with other GSNs, which is obtained by the SGSN in the operation before this moment. In this path information table, there are paths in two states, the faulty path and available paths, if the GTP path information table is empty, that is, in the previous operation of SGSN, the GTP path has not been established or has been deleted, in this case, all paths are regarded as available paths;

[0032] For the faulty path in the current path information table, the SGSN periodically sends ECHO messages to the faulty path for detection...
