Wireless communication core network and method for analyzing user equipment mobility in the same

A wireless communication core network, comprising:

• an access and mobility management function (AMF), being configured to serve at least one user equipment (UE);
• a unified data management (UDM), being configured to store an identity of the AMF;
• an application Function (AF), being configured to make an analysis request for a mobility analytics report of the at least one UE, wherein the analysis request comprises first UE mobility information of the at least one UE;
• and
• a network data analysis function (NWDAF), being connected to the AMF, the UDM, and the AF, and being configured to:
• obtain the identity of the AMF from the UDM on its own or via a network exposure function (NEF) according to the analysis request;
• obtain second UE mobility information of the at least one UE from the AMF according to the identity;
• and
• generate and transmit the mobility analytics report to the AF according to the first UE mobility information and the second UE mobility information.
