Abstract: A 5G or pre-5G communication system is provided to support higher data transmission rates after 4G communication systems such as LTE. To support communication of a terminal that dually accesses a first radio access technology (RAT) communication system and a second RAT communication system, a session generation request message for transmitting traffic is received from a terminal. A target communication system that is to generate a data path with respect to the traffic from the first RAT communication system and the second RAT communication system is determined, the data path for the target communication system is configured, and information about the configured data path is transmitted to the terminal.

Abstract: The present invention relates to a 5G or pre-5G communication system for supporting high data throughput beyond the 4G communication systems such as LTE. A method for a server for supporting the mobility of a user equipment (UE) in a mobile communication network comprises the steps of: establishing an IP flow with the UE utilizing a first IP address to transceive data; receiving a message comprising a second IP address allocated to the UE and an identifier for the IP flow; generating a tunnel interface for communicating with the UE having the second IP address as the ending IP address, and binding the IP flow allocated to the identifier to the generated tunnel interface; and transceiving data with the UE by means of the tunnel interface.
