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.
