  • Patent number: 11997761
    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.
