a controller coupled with the transceiver and configured to:
receive, from a first session management function (SMF), a first message including information indicating that a transfer of a session management (SM) context to a second SMF;
transmit, to the second SMF, a second message for requesting the second SMF to receive the SM context from the first SMF;
start a timer upon transmitting the second message;
receive, from the second SMF, a third message as a response to the second message before expiration of the timer;
receive, from another AMF, a user equipment (UE) context transfer request due to a terminal mobility, before receiving the third message; and
delay a processing of the UE context transfer request with the second SMF until receiving the third message.
