Abstract: A method of controlling congestion of network equipment that connects networks with each other, includes determining a type of congestion based on a location of the network equipment; and identifying a network connection section having a strong possibility of occurrence of congestion based on the type of congestion, and setting a critical congestion bandwidth that is used to determine the occurrence of congestion. Further, the method includes identifying users required for equal distribution of traffic upon occurrence of congestion based on the critical congestion bandwidth; and equally distributing traffic to the identified users based on the critical congestion bandwidth, and then dropping an excess of arriving traffic over the equally distributed traffic, thereby performing avoidance of the congestion.

Abstract: Disclosed is a method of ensuring a service continuity based on a utility slice in case of a handover. The method includes receiving a handover request message from a source base station when a user equipment (UE) moves from a coverage of the source base station to that of a target base station, setting a session for the UE based on slice information included in the handover request message, and transmitting a handover request acknowledgment (ACK) message for the handover request message to the source base station, wherein the target base station may provide, when a service slice corresponding to a service provided from the source base station to the UE through a protocol data unit (PDU) session is not supported by the target base station, the service using a utility slice.
