Abstract: A traffic management server is configured to determine a base station at which a handover occurs to a base station having a slower maximum communication speed as an area boundary base station, determine a terminal located within a coverage of the area boundary base station, and instruct a control apparatus included in a mobile network to limit a maximum usable bandwidth of the determined terminal.

Abstract: Provided is a technique of finely performing congestion determination and congestion control on a cellular communication system employing a C-RAN architecture. An instruction is given to a control device to acquire location information of a terminal in a cell of a C-RAN using a first message between network nodes, acquire a congestion indicator of the cell of the C-RAN using a second message between the network nodes, determine the occurrence of congestion of the cell based on the congestion indicator, identify a terminal staying in a cell in which congestion is occurring based on the location information of the terminal, and limit a maximum usable bandwidth of the specified terminal.
