1. A method performed by a first base station which supports an alternative quality of service (QoS) profile function and a QoS flow establishment pending function in a wireless communication system, the method comprising:
receiving, from a terminal, a message including a QoS flow establishment request and a QoS profile list request;
storing the QoS flow establishment request and the QoS profile list request, in case that the first base station is in a congested situation;
selecting a highest QoS profile among one or more alternative QoS profiles included in the QoS profile list request;
transmitting a first message to a second base station; and
receiving a second message in response to the first message from the second base station,
wherein the first message includes:
an indication that the QoS flow establishment request of the terminal is in a pending state and the selected highest QoS profile.
