Problems solved by technology

However, in the case of such network sharing, each operator may set different auxiliary information for their respective UEs. As a result, when a certain user equipment receives multiple different auxiliary information issued by the 3GPP access network, due to the user equipment It is impossible to identify which carrier the received auxiliary information belongs to, which may result in failure of service transfer

Embodiment Construction

[0037] The technical solutions of the present invention will be further described in detail below through the accompanying drawings and embodiments.

[0038] see figure 1 The illustrated embodiment of the present invention provides a schematic diagram of a network structure of a mobile communication system 3GPP access network sharing. Operators A, B and C share the same 3GPP access network, and operators A, B and C have their own public land mobile network identities (PLMN IDs). Based on the network structure, in the embodiment of the present invention, the 3GPP access network entity can deliver the PLMN ID and the auxiliary information corresponding to the PLMN ID in the system broadcast message, and the user equipment can determine the corresponding PLMN ID for each operator. Auxiliary information for service transfer for specific operators.

[0039] figure 1 , the network sharing scenarios include but are not limited to the following two:

Abstract

The present invention relates to a service transfer method, user equipment and access network equipment, comprising: the user equipment receives a public land mobile network identifier (PLMN ID) sent by a 3GPP access network entity and auxiliary information corresponding to the PLMN ID, and the PLMN The auxiliary information corresponding to the ID is used for the user equipment to transfer services to the wireless local area network WLAN that the operator corresponding to the PLMN ID allows the user equipment to access; the user equipment corresponds to the PLMN ID according to the PLMN ID Auxiliary information for business transfer. The technical solution provided by the embodiment of the present invention can improve the success rate of service transfer.

Description

technical field [0001] The present invention relates to the field of mobile communications, and in particular, to a service transfer method, user equipment and access network equipment. Background technique [0002] Currently, non-The3rd Generation Partnership Project (non-3GPP) networks (eg, Wireless Local-Area Network, WLAN) can be used for 3GPP networks (eg, Long Term Evolution (Long Term Evolution, The offload of part or all of the services of the LTE) network) relieves the traffic load of the 3GPP network. User Equipment (UE) can access the LTE network and the WLAN at the same time, and the LTE network can control the resource scheduling of the WLAN, so that part or all of the services of the UE in the 3GPP network are streamed to the WLAN. When the service is offloaded, the UE can receive auxiliary information from the access network discovery and selection function (ANSDF) or the 3GPP radio access network (Radio Access Network, RAN), and the auxiliary information is ...
