Abstract
In a location change reporting method, a session management function entity receives from a mobility management entity information including location change information of user equipment (UE) in a first presence reporting area (PRA), an identity of the first PRA, and an identity of a PRA set that includes the first PRA. The session management function entity identifies, based on the identity of the PRA set and locally stored PRA subscription information, a subscription entity that subscribes to location change events of the UE in the PRA set, and sends the identity of the first PRA and the location change information of the UE in the first PRA to the subscription entity.
