Method and system for sensing user end access style in core network

Abstract

The invention relates to a method for making corn network sense user access type, wherein at the access network node, it reports user access type to the corn network node, to make the corn network node sense user access technique. And the invention provides a relative system which comprises user terminal, access network node, corn network node, while the access network node comprises state refresh request receiver and user access technique type reporter; the state refresh request receiver receives the user state refresh request; the reporter reports the user access technique type to the corn network node. The invention has high reliability and compatibility.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a method and system for realizing core network perception of user end access technology type. Background technique [0002] The future network will be a network in which multiple user access technologies (RAT) coexist, such as GSM access network GERAN, WCDMA terrestrial radio access network (UTRAN), wireless local area network (WLAN) access methods and future LTE access network. Under the same access network system, it can also be divided into multiple access methods, such as WCDMA high-speed downlink data access (HSDPA) method. The next-generation wireless core network needs to be compatible with multiple RATs at the same time. Users can use multi-mode terminals to roam and access services on multiple access networks. When a user accesses or initiates a service request, the network needs to know the RAT currently used by the user for subsequent service processing, s...

Problems solved by technology

[0005] In the above-mentioned existing technologies, the implementation in the process is fixedly configured. Usually, the default access technology of the 2G interface is GSM access, and the message transmitted by the 3G interface defaults to WCDMA access. Type to determine the specific access technology used by the user. For example, the service accessed through the Gb interface defaults to the common GSM channel at the user end, and the service accessed through the lu interface defaults to the common UTRAN channel; however, when multiple When two different access technologies share an interface (for example, through the same Gb interface, the client can use the common GSM channel to access, or can access through the EDGE channel), the core network cannot judge the interface type Which access technologies are used by the client

Furthermore, in the same access network system, multiple access methods can also be provided, such as WCDMA high-speed downlink data access (HSDPA) and wireless local area network (WLAN). different types of access technologies, resulting in the core network being unable to perceive the types of access technologies at the user end
