Method and device for establishing general packet radio service gprs connection

Abstract

The invention discloses a method and device for establishing general packet radio service (GPRS) connection. The method includes: analyzing an access point name (APN) analysis request sent by a received service GPRS support bode (SGSN); acquiring the state information of a gateway GPRS support node (GGSN) and the load information of the GGSN when it is determined that the type of the APN included in the APN analysis request is a general APN; according to the load information, determining the weight factor of each GGSN loading GPRS service; according to the weight factors and the state information of the GGSN, configuring GGSN address information; and feeding back the configured GGSN address information to the SGSN, wherein the SGSN establishes the GPRS connection according to the received GGSN address information. The method and device for establishing the GPRS connection is capable of improving the utilization rate of the capacity of a GGSN device in a better way and obtaining the work state of the GGSN device dynamically and improving the reliability of the whole GPRS system.

Description

Technical field [0001] The present invention relates to the technical field of core network data processing, in particular to a method and device for establishing a general packet radio service (GPRS, General Packet Radio Service) connection. Background technique [0002] GPRS introduces the concepts of packet switching and packet transmission, thereby enabling the Global System for Mobile Communications (GSM) to support data services from the network system. In specific implementation, the GPRS network is another network superimposed on the GSM network. That is to say, the GPRS network adds GPRS service support node (SGSN, Service GPRS Support Node) and gateway GPRS support node (GGSN, GatewayGPRS Support Node) and other functional entities. [0003] Among them, SGSN is used to perform mobility management, session management, and route selection for mobile stations (MS, Mobile Station), establish a data transmission channel between MS and GGSN, and receive data sent by BSS / RNS tr...

AI Technical Summary

Problems solved by technology

[0014] With the increase of GPRS traffic and the evolution of technology, there will be multiple GGSN devices in the communication network at the same time. These GGSN devices may correspond to different device manufacturers and have different business processing capabilities, for example, the throughput between devices Different, but in the prior art when establishing a GPRS connection, in the GGSN address list returned by DNS, it is not possible to directly configure the GGSN address list by considering the business load and operating status of the GGSN

In this way, in the configured GGSN address list, the GGSN service sharing ratio at the top of the address list is inconsistent with the actual processing capability of the device, resulting in low capacity utilization of the GGSN device

And if according to the technical solution proposed in the prior art, the DNS cannot dynamically know the running status of the GGSN in real time. There are GPRS service connections pointing to the faulty GGSN equipment, which makes the reliability of the entire GPRS system low

[0015] To sum up, in the prior art method for establishing GPRS connection, the capacity utilization rate of GGSN equipment is low, and the working status of GGSN equipment cannot be known, which makes the reliability of the entire GPRS system low
