changing the edge server providing a service for the UE from a first edge server to a second edge server according to movement of the UE;
changing the core network apparatus communicating the user packet related to the UE via a radio access network from a first core network apparatus to a second core network apparatus; and
continuing providing the UE, by the second edge server via the second core network apparatus, with the service provided by the first edge server via the first core network apparatus for the UE by using a same IP address allocated to the UE for providing the service to the UE by the first edge server.
