Title: METHOD, DEVICE, AND SYSTEM FOR REPORTING LOCATION CHANGE
Abstract:
The present invention provides a method, device, and system for reporting a location change, for use in at least solving the problem that when a location change event of a UE in a PRA is subscribed to by using a PRA set identity (ID) in a current multi-PRA scenario, a session management function entity cannot decide how to report the location change event of the UE in the PRA to a subscription entity since the location change event of the UE in the PRA reported by a mobility management entity only carries the PRA ID(s). The method comprises: a session management function entity receives location change information of a UE in a PRA, the PRA ID, and the ID of a PRA set to which the PRA corresponding to the PRA ID belongs sent by a mobility management entity; the session management function entity determines, according to the ID of the PRA set and stored PRA subscription information, a subscription entity subscribing to a location change event of the UE in any PRA of the PRA set; the session management function entity sends, to the subscription entity, the PRA ID and the location change information of the UE in the PRA. The present invention is applicable to the technical field of communications.
