Method, equipment and system for switching isomerization access network

Abstract

The invention discloses a method for user equipment switching among heterogeneous access networks comprising: receiving service information which user equipment anticipate in switching, acquiring service gateway address information of user equipment used at source access network, acquiring target service gateway address corresponding to service information which user equipment anticipates in switching from service gateway address information and service information which user equipment anticipates in switching; initiating a connection establishment for corresponding target service gateway and switching the user equipment to corresponding target service gateway. The invention simultaneously discloses an access gateway and user equipment. In the invention, user equipment with multiple access abilities can selectively switching partial service to target network side for continuous using so that user equipment can select certain access technology for specific service, thereby implementing better user experience.

Description

technical field [0001] The invention relates to network switching technology, in particular to a method, device and system for heterogeneous access network switching. Background technique [0002] With the development of network convergence technology and the diversification of user service requirements, user equipment (UE, User Equipment) is required to access the 3GPP core network through the third generation mobile communication standardization partnership project (3GPP, 3rdGeneration Partnership Project) access network, It is also possible to access the 3GPP core network through a non-3GPP (non 3GPP) access network, such as a wireless local area network (WLAN, Wireless Local Area Network), a World Interoperability for Microwave Access (WiMAX, World Interoperability for Microwave Access) and other access networks. That is to say, different types of access technologies access the 3GPP core network through their respective access networks, thereby obtaining an IP address as...

Problems solved by technology

For example, when a user initiates multiple service connections in the coverage area of ​​a single access network, when a new access network is detected, some services can be performed according to the service information that the UE expects to switch (for example, the service that is expected to be switched according to the UE preference) Connection switching, so as to realize a fine-grained switching mode, but in the prior art, after the connection is established, all the services used by the user on the source access network side are migrated to the target access network side, which cannot be realized according to the policy. Switch some business connections
