Problems solved by technology

[0010] The main purpose of the present invention is to provide a method for obtaining a user's access to the home GGSN, so as to solve the problem in the prior art that roaming users in the network who sign up for a WildCard (wild card) cannot use their home GGSN to access. Various subscribers provide better GPRS services

Embodiment Construction

[0040] The core idea of ​​the present invention is to assign a default APNNI to a roaming user in the network who subscribes to a WildCard during the activation process of the PDP context of the packet data protocol. Then customize the APN for the user according to the assigned APNNI. According to the rules customized by APN, the IP address of the GGSN where the user belongs can be resolved, so as to connect the user to the external data network that the user needs to access.

[0041] refer to figure 2 , figure 2 The implementation process of a preferred embodiment of the method of the present invention is shown, including the following steps:

[0042] Step 201: After receiving the activation request message of the user, the SGSN performs subscription data matching of the user according to the information carried in the message.

[0043] Those skilled in the art know that when a user attaches, the SGSN obtains the user's IMSI, and then the SGSN obtains the user's subscripti...

Abstract

This invention discloses a method for obtaining GGSN address of user access home place, which assigns default APNNI for signed users of abnormal cards in the activation process of context of PDP to draft the APN of the user and analyze the domain name to the APN to turn out the GGSN address of user home places. This invention also discloses a NE device for obtaining the home place of the user including: a R-T unit, a data matching unit, a network identification unit and a drafting unit for APN.

Description

technical field [0001] The present invention relates to the field of mobile communication, in particular to a method and network element equipment for acquiring a user's access home GGSN. Background technique [0002] In the GPRS / UMTS (General Packet Radio Service / Universal MobileTelecommunications System, General Packet Radio Service / Universal Mobile Telecommunications System) packet domain core network, the SGSN (Serving GPRS Support Node) mainly completes the routing and forwarding, encryption and authentication of packet data packets. Authorization, session management, mobility management, logical link management, CDR generation and output and other functions. The position of SGSN in the mobile communication network is as follows: figure 1 Shown: [0003] SGSN needs to complete the routing and data forwarding functions of service data between MS (Mobile Station) users and GGSN (Gateway GPRS Support Node). SM (Session Management, session management) in SGSN is a main c...
