Gateway GPRS support node apparatus

Abstract

A GGSN device supported by gateway GPRS is composed of an interface module, a routing module for encapsulating the non-capsulated data with ID parameter according to routing list and routing them out, a central control module including traffic counting unit and routing list processing unit for routing selection, a content analyzing module for receiving the non-capsulated data from the routing module and analyzing their APN parameters, and an ID generating module for receiving the analyzed result from contents analyzing module, generating ID parameters and sending them to routing module and central control module.

Description

technical field [0001] The present invention relates to a Gateway GPRS Support Node (Gateway GPRS Support Node, GGSN for short) device, in particular to a GGSN device which controls and distinguishes service types by controlling and analyzing APN parameters of routing data packets. Background technique [0002] Existing GGSN equipment provides routing encapsulation for data packets of packet data services, and its functions mainly include service platforms outside the mobile communication network, such as MMS platforms, SMS platforms, and mobile business operation support systems (Business & Operation Support System, BOSS for short). ) interface functions such as billing platforms, routing functions for sending data to mobile terminals and data outside the mobile network, and session establishment and management functions. To accomplish the above functions, the existing GGSN mainly includes the following parts: [0003] The central control module is used to receive and anal...

AI Technical Summary

Problems solved by technology

[0006] 1. The central control module of GGSN needs to statistically analyze the received business information one by one, which has a large amount of data and low processing efficiency;

[0007] 2. GGSN does not identify the APN parameters in the service data, and the mode of generating bills and encapsulating data is single

For example, GGSN cannot distinguish information with different levels of confidentiality in APN parameters, such as special information for public security and medical systems, and general business information, while GGSN randomly selects a route according to the same mode to encapsulate and send, and the data service server that receives the information, such as MMS Centers, etc., have no way of identifying their corresponding security levels, resulting in some systems with high security requirements having to set up dedicated lines, resulting in a waste of resources

[0008] 3. GGSN itself cannot differentiate services

Therefore, for services that are not billed according to traffic, the behavior of GGSN to count traffic wastes system resources, and the troubleshooting operation of the billing system also causes a burden on the billing system

[0009] To sum up, the existing GGSN equipment has the defects of concentrated processing data volume and the inability to identify and distinguish service types, and this defect leads to low efficiency and waste of resources for troubleshooting in the corresponding billing system

[0010] At the same time, the existing GGSN equipment cannot identify and distinguish service types, nor can it overcome the shortcomings of single mode of generating bills and encapsulated data and unhelpful traffic statistics
