Problems solved by technology

Not only is the configuration work complicated, but also when the APN changes, the configuration information on the HLR, SGSN, and GGSN needs to be modified one by one, resulting in a large maintenance workload

Embodiment Construction

[0077] The core of the present invention is aiming at the requirement of UE to access multiple public data networks, combining single access point information and user's special information to allocate different addresses for UE to realize access to different public data networks.

[0078] If the operator uses a unified APN to carry out various services, the SGSN can only resolve to the same GGSN according to the APN. GGSN is connected to multiple different public data networks. In order to distinguish the routes to different public data networks, the present invention allocates different address pool segments according to user information, so that GGSN can configure access to different public data networks according to these different address pool segments. The routing of the data network enables the UE to access different public data networks. If the address needs to be allocated by the GGSN, configure different address pool segments on the GGSN according to the user informa...

Abstract

The invention discloses a method for accessing a public data network, including: setting up a unified name for the access points for all the public data networks. It establishes a corresponding relationships between the user identification and the public data networks, then it distributes an IP address for the user according to the above corresponding relationships when the user accesses. Gateway equipment which connects with the public data networks connects the user access to the target public data network based on the IP address. The invention also discloses a system for accessing a public data network, including: gateway equipment, Users' Mobility managing equipment and a Belongingness managing device.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a public data network access method and system. Background technique [0002] With the rapid development of mobile communication, people's demand for various services in communication has prompted the birth of 3G (Third Generation) mobile communication, whose main feature is the comprehensive integration of mobile communication and Internet on the basis of IP. [0003] like figure 1 As shown, the 3GPP (Third Generation Partnership Projects, Third Generation Partnership Project) network consists of UE (User Equipment), UTRAN (Universal Terrestril Radio Access Network, Universal Terrestrial Radio Access Network) and CN (Core Network, core network) . Among them, UTRAN is responsible for functions such as soft switching, access and congestion control, and radio resource allocation. The CN mainly includes a serving GPRS (General Packet Radio Service, General Packet Ra...
