METHOD FOR DETERMINING TARGET, NETWORK ELEMENT AND SYSTEM FOR DETERMINING TARGET

摘要

Disclosed are a method for determining a target, a network element and a system for determining a target, which relate to the technical field of communications, solving the problem that an access network cannot acquire a service without the permission of a user equipment, and the time delay of the access network is too great, and the problem that the operator-user attachment rate is low, and the roaming fee of a user equipment is too high. The method comprises: an access network element receives access control information about a user equipment (UE) sent by a mobility management network element, wherein the access control information contains an identifier of a public land mobile network (PLMN) and the ratio access type (RAT) permitted and/or not permitted by the PLMN, and the access network element determines a target for the UE according to the access control information. The present invention can be applied to a shared network environment.
