Abstract: A traffic mobility method between heterogeneous access networks of a wireless communication system includes, as a user equipment (UE) multiply accesses a first access network and a second access network, configuring a first transmission path corresponding to the first access network and a second transmission path corresponding to the second access network with respect to the UE, by a gateway, determining whether traffic mobility is performed on each traffic flow based on a traffic mobility policy of the each traffic flow served to the UE through the first transmission path and a transmission state of the second access network, by a control entity, and changing a transmission path of a traffic flow on which traffic mobility is determined, to the second transmission path from the first transmission path, by the gateway.

Abstract: A method for access traffic steering, switching, and splitting (ATSSS) in a network and a network entity for performing the method are disclosed. When the execution of the ATSSS from the first access network to the second access network is determined, a first message requesting the SMF to confirm the connection state of the terminals for the first access network and the second access network may be transmitted to AMF. The SMF may receive information on the connection state of the terminal from the AMF.
