Description

technical field

[0001] The invention relates to the communication field, in particular to a method and system for accessing a home packet data network. Background technique

[0002] Mobile packet data services are widely used rapidly due to their advantages such as convenient mobility, high-speed transmission rate, and rich mobile data services, as defined in the standard protocol of 3GPP (3rd Generation Partnership Project, third-generation mobile communication standardization partner project) The GPRS (General Packet Radio Service, general packet radio service) / WCDMA (Wide (band) Code Division Multiple Access, wideband code division multiple access) system enables mobile terminals to access packet data services. In these systems, SGSN (Serving GPRS Support Node, service GPRS support node), GGSN (Gateway GPRS Support Node, gateway GPRS support node) and DNS (Domain Name System, Domain Name System) equipment in the system are connected through the Gn interface , to implemen...
