Method and apparatus for providing congestion control for application in wireless communication system

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to control the transceiver to:
• receive, from a user equipment (UE), a non-access stratum (NAS) message,
• transmit, toward a first mobility management entity, a first initial UE message including the NAS message,
• receive a reroute message including the first initial UE message transmitted from the first mobility management entity, in case that a reroute is determined by the first mobility management entity,
• identify a second mobility management entity supporting a dedicated core network for the UE, based on the reroute message, and
• transmit, to a second mobility management entity, a second initial UE message including the NAS message supporting the dedicated core network for the UE,
• wherein the second mobility management entity is selected based on a selected public land mobile network (PLMN).

A method performed by a first mobility management entity in a wireless communication system, the method comprising:

• receiving, from a base station, a first initial user equipment (UE) message including a non-access stratum (NAS) message;
• and
• transmitting a reroute message including the first initial UE message, in case that a reroute is determined by the first MME,
• wherein in case that the reroute message is transmitted, a second initial UE message including the NAS message is transmitted to a second mobility management entity supporting a dedicated core network for the UE,
• wherein the second mobility management entity supporting the dedicated core network is identified based on the reroute message, and
• wherein the second mobility management entity is selected based on a selected public land mobile network (PLMN).
