Claim 1:
2. A method for receiving a service by a User Equipment (UE), the method comprising:
forwarding, toward an edge server, user data included in a user packet sent from the UE in a case where a core network apparatus determines that a destination of the user data is the edge server:
forwarding, toward a session anchor connected to a data network, the user data included in the user packet sent from the UE in a case where the core network apparatus determines that the destination of the user data is not the edge server;
receiving, from a first radio access network via a first core network apparatus that forwards the user packet related to the UE, a service sent from a first edge server; and
continuing receiving, from a second radio access network via a second core network apparatus that communicates the user packet related to the UE, the service sent from a second edge server by using a same IP address allocated to the UE for providing the service to the UE by the first edge server in case of changing from the first edge server to the second edge server and changing from the first core network apparatus to the second core network apparatus according to the movement of the UE.
