Description

A kind of method for switching network, Apparatus and system

A kind of method for switching network, apparatus and system technical field

The present invention relates to the communications field, more particularly to a kind of method for switching network, apparatus and system.

Background technology

Now, in order to mitigate the network congestion with developing rapidly for mobile Internet caused by the data traffic of sharp increase, operator is provided with wireless access technology WLAN (the Wireless Local Access Network, WLAN that link data rates are high, equipment investment cost is cheap）.Simultaneously for the service experience of the guarantee user in the case where wide area cellular network is in poor service, one kind is formd now based on wide area cellular networks, WLAN as local focus cover supplemented by heterogeneous network, WLAN is widely used in wide area cellular networks as focus covering in the heterogeneous network, the access of high data rate not only so can be provided for low-speed mobile users in hot zones, using the extensive coverage of wide area cellular networks service can also be provided the user under the scene of user's high-speed mobile, and then realize wide area cellular networks and WLAN mutual supplement with each other's advantages, effectively it make use of Radio Resource.

But inventor has found, the switching between existing WLAN and cellular network generally occurs in core-network side, but WAP and the access device of cellular network due to WLAN（Such as, base station）It is to be connected by respective gateway with internet, therefore, when UE is switched between cellular network and WLAN, it is necessary to notify cellular network or the corresponding gateways of WLAN, so as to be related to the interaction between core net so that switching flow is complicated and switching time is long.For example, by taking LTE as an example, MME is generally responsible for location management in LTE, when UE switches out the tracing area of MME management, MME will complete the location management of UE after switching by tracking area update flow.Accordingly, it is typically that UE route registration is considered as customer location management in WLAN, i.e. UE is registered on WLAN WAP carries out location management to UE.And need the WAP with WLAN to be associated because WLAN and LTE access networks are orthogonal, therefore when UE is switched to WLAN from LTE, complete the registration of routing iinformation.UE after so switching is complete Total detachment MME management so that LTE systems will be unable to learn the location of current UE.And then cause follow-up UE from WLAN be switched to LTE when, the routing iinformation page that UE is registered on WLAN WAP can not be transmitted to LTE MME, so that UE needs to register in MME again, LTE location management could be realized, so as to increase the time delay of switching, also make it that switching flow is excessively complicated.The content of the invention
