A method integrates network elements in an integration Internet protocol (ALL-IP) network based on a next generation mobile communications network. For the purpose, the method integrates a packet control function (PCF) for interworking a radio access network (RAN) with a packet data network and a packet data serving node (PDSN) function for performing a function as an access node to enable data terminals to communicate with the packet data network through the RAN, and integrates, in case of providing a mobile Internet protocol (mobile IP) service, a mobile Internet Protocol foreign agent (mobile IP FA) of the PDSN and a link layer termination function of a mobile station in the PCF.
