Embodiment Construction

[0046] In order to make the object, technical solution and advantages of the present invention clearer, specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0047] The core idea of ​​the present invention is: add a GGSN agent functional entity in the access system of the existing roaming user's home, and for the access of the general APN, the GGSN agent acts as an intermediate forwarding station, and forwards the user's context request To the home GGSN of the user's subscription network, the home site directly processes the user's activation request and subsequent processing of various data services.

[0048] In order to realize roaming to other PLMN GPRS users' home access, the present invention builds a set of GGSN proxy (proxy) gateway equipment in the gateway office to increase a GGSN proxy function body. After adding the GGSN agent function body, it has no effect on the SGSN in the roaming area. I...

Abstract

The invention provides an accessing method and system in belonging area for roaming user, the method includes following steps: when the roaming user accesses the network, if it applies the general name of accessing point APN, the gateway GPRS support node CGSN agent functional entity transmits the message from GPRS support node CGSN to belonging area GGSN, and the GGSN in belonging area processes the user messages and realize the data transmission of SGSN, and it realize the access in belonged area for roaming users. It can realize that the roaming GPRS user processes the requirement of GPRS service back to signed belonging area, and makes the local running trader can develop the incremental value business, ensure the GPRS is open to prepaid user, and realize the real-time charging of data service.

Description

technical field [0001] The present invention relates to mobile communication technology, specifically, to a roaming user's home access method and system. Background technique [0002] Gateway GPRS Support Node (GGSN) and Service GPRS Support Node (SGSN) are two basic devices in the GPRS / WCDMA packet domain core network. The main function of SGSN is to provide radio access network (UTRAN) / base station subsystem (BBS) The main function of the GGSN is as a gateway between the GPRS / WCDMA system and the external packet data network (PDN). The positions of SGSN and GGSN equipment in the GPRS / WCDMA network are shown in Figure 1. [0003] The data service initiated by the mobile packet data user is accessed through the SGSN equipment, sent to the GGSN, and finally sent to the external packet data network through the GGSN. When a user initiates an access request, an access point name (APN) must be specified. The access point name (APN) is used in GGSN to identify a specified exter...
