Problems solved by technology

However, this method greatly restricts the flexibility of network layout. When the networks controlled by different operators are upgraded, relocated, and settings are changed, the information cannot be modified in time, which may lead to unsuccessful access of user terminals or inability to access services.

Embodiment Construction

[0030] The shared core control entity in the embodiment of the present invention may be an HSS, and the local core control entity may be an AAA Server or AAAProxy. When the user terminal is in the visiting place, the AAA Proxy controls and manages the user, and the AAA Proxy gets in touch with the HSS through the AAA Server to obtain user and home network information. The data gateway is a data gateway of a converged network formed based on the early technological evolution of the 3GPP network, and can support two different mobility management protocols, GTP and MIP. The access control function entity is a mobility management entity in the 3GPP access network, such as MME or SGSN; in the non-3GPP access network, it is the local core control entity AAA Server or AAAProxy, or a non-3GPP access network gateway, or It is composed of the local core control entity of the home location and the non-3GPP access network gateway, or is composed of the local core control entity of the vis...

Abstract

The invention discloses a gateway selecting method comprising that a mapping table requester sends a network configuration request to a mapping table owner; the mapping table owner sends a mapping table of mobility management protocol ability of APN to the mapping table requester. The invention also discloses another gateway selecting method comprising that an access control function entity selects a gateway and obtains the address of data gateway according to the mobility management protocol ability of APN. The invention also discloses a gateway selecting device comprising a transmit-receive unit, an enquiring unit and a processing unit. According to the invention, a data gateway and a local service gateway can be selected flexibly to assure the consistency of user services.

Description

technical field [0001] The embodiment of the present invention relates to the field of mobile communication, in particular to a method for realizing gateway selection. Background technique [0002] Traditional telecommunication networks, especially wireless communication networks, such as Global for Mobile Communications (GSM) and Universal Mobile Telecommunications System (Universal MobileTelecommunications System, UMTS), have the advantages of rich types of services and strong network control capabilities. Due to factors such as limited frequency resources and harsh transmission environment, the communication system cannot provide high access rate, and the emerging broadband wireless access technology well makes up for these shortcomings. Broadband wireless access technologies represented by Wireless Local Area Network (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX) can provide high-speed broadband wireless access services and support nomadic And mobile...
