receiving a network registration request message from a terminal;
determining whether the terminal requires support for access traffic steering, switching, splitting (ATSSS);
in case that the terminal requires support for the ATSSS, requesting information about an AMF device supporting the ATSSS from a network repository function (NRF) device;
receiving, from the NRF device, information about at least one candidate AMF device supporting the ATSSS;
selecting an AMF device to perform a network registration procedure for the terminal, based on the information about the at least one candidate AMF device; and
transmitting a re-route request message including information about the selected AMF device to a base station.
