Embodiment

In order to make the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the present invention is described in further detail, and obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making other embodiments all obtained under creative work prerequisite, belong to the scope of protection of the invention.

In the scheme of the embodiment of the present invention, network is in the process of carrying out load balancing, LTE evolved base station (E-UTRANNodeB, eNB) by operation management maintain (Operations, AdministrationandMaintenance, OAM) or pre-configured mode obtain the relevant information of wlan network.Specifically, to provide two kinds of concrete solutions as follows for this embodiment:

Scheme one: RAN side provides supplementary to subscriber equipment (UserEquipment, UE) by broadcast signaling or dedicated signaling.The information that the supplementary that UE utilizes RAN side to provide, the metrical information of UE, WLAN provide, and from access network discovery and selection function unit (AccessNetworkDiscoveryandSelectionFunction, ANDSF) strategy obtained or pre-set strategy, by service distributing to WLAN or RAN side.

Scheme two: network is selected and the specific rules of service distributing is specified by RAN side standard, and RAN provides Parameters threshold required in RAN rule by broadcast and/or dedicated signaling.When there is not ANDSF rule in network, UE according to the fixed shunting rule of RAN side mark by service distributing on WLAN or 3GPP; When to there is ANDSF simultaneously, ANDSF rule precedence is in RAN rule.

The embodiment of the present invention in conjunction with above scheme one and scheme two, can also be carried out fusion and obtains following scheme: RAN side provides supplementary to UE by broadcast signaling or dedicated signaling.If network and with supporting ANDSF per family, the supplementary that UE can utilize RAN side to provide, and obtain distributing strategy from ANDSF, by service distributing to WLAN or RAN side.If network or user do not support ANDSF, the supplementary that UE can utilize RAN side to provide, and according to strategy pre-set in RAN agreement, by service distributing to WLAN or RAN side.Further, RAN side can also provide alternative WLAN mark (Identity, ID), so that UE can find target WLANAP to shunt fast at broadcast signaling or dedicated signaling.

Above-mentioned each scheme can be good at the problem solving service distributing.

And in scheme after above fusion, service distributing can support the service distributing of APN (AccessPointName, APN) rank, but can't support the service distributing carrying (Bearer) rank.Because LTEeNB obtains the relevant information of relevant wlan network by OAM or pre-configured mode, information updating causes shunting effect not good not in time.For this technical problem, the technical scheme that the embodiment of the present invention further provides further depth optimization is specific as follows:

UE starts satisfactory WLANAP around active searching and the information that will report of active obtaining after receiving the order of this RRC signaling, carry out information reporting afterwards by new RRC signaling to LTEeNB.

LTEeNB can determine whether the business of these UE to be unloaded in certain WLANAP network according to these information after receiving reporting information.

After UE and WLANAP connects, LTEeNB can also send new " WLAN measures configuration " RRC signaling, require that certain UE carries out periodically or triggering the reporting of event the information of connected WLANAP, so that LTEeNB grasps the up-to-date information of neighbouring WLANAP more in time, accurately.The information that LTEeNB can also utilize these UE to report needs for follow-up the UE service using wireless side degree of depth fusion characteristics, to avoid all UE all to measure, reduces the energy consumption of UE.

RRC signaling also can by MACCE order in the above description, or Layer1 control signal realizes, and the signaling embodiment of the present invention of specifically carrying instruction is not made uniqueness and limited.
