Abstract: A method for managing congestion in a base station in a mobile communication system according to one embodiment of the present invention comprises the steps of: requesting user subscription information to a mobility management entity (MME); receiving the user subscription information from the MME; and performing a congestion control in a communication between terminals on the basis of the received user subscription information. According to the embodiment, action may be taken in consideration of the user information and a current congestion state when controlling the congestion in a wireless communication system, and thus side effects resulting from the congestion control may be reduced. Further, the present invention provides a method and device for not charging for dropped packets when performing a packet drop, and thus the congestion control may be performed more easily. Also, the present invention has an advantage of performing the congestion control, according to the type of packets to which congestion control is applied or the type of application or service which has generated packets, at the time of controlling the congestion, thereby minimizing user's inconvenience due to the congestion control.

Abstract: The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services.Methods and apparatuses provide a service to user equipment through a dedicated core network. In one method, a base station, also referred to as eNB, receives a non-access stratum (NAS) message from user equipment (UE), and transmits a first initial UE message having the NAS message to a first mobility management entity (MME). Also, the base station receives a redirection request message having the NAS message from the first MME, and transmits a second initial UE message having the NAS message to a second MME. In another method, the MME receives the first initial UE message having the NAS message from the base station, and transmits the redirection request message having the NAS message when the MME fails to support a dedicated core network according to UE usage type information. If the redirection request message is transmitted, a second initial UE message having the NAS message is transmitted to a dedicated MME.
