Abstract: In a wireless communication core network, an Application Function (AF) make an analysis request for a mobility analytics report of a UE, which includes first UE mobility information of the UE. In the wireless communication core network, a Network Data Analysis Function (NWDAF) obtains an identity of an Access and Mobility Management
Function (AMF) serving the UE from a Unified Data Management (UDM), on its own or via a Network Exposure Function (NEF), based on the request. Then, the NWDAF obtains second UE mobility information of the UE from the AMF according to the identity of the AMF, and generates and transmits the mobility analytics report to the AF according to the first and second UE mobility information.
