1. A method for operating an apparatus that performs traffic control in a wireless communication system, the method comprising:
- receiving information about a terminal to be controlled, the information including an allocation and retention priority (ARP) value requested to be change;
identifying the terminal to be controlled based on the ARP value requested to be changed, wherein the ARP value requested to be changed is greater as traffic usage of the terminal to be controlled is greater;
detecting a congestion situation in a cell based on a ratio of terminals having a throughput equal to or less than a predetermined threshold value in the cell; and
changing a parameter relating to scheduling of the terminal to be controlled, according to the detection of the congestion situation.

11. A method for operating a management server in a wireless communication system, the method comprising:
-
receiving information on traffic usage of a plurality of terminals from a gateway; and transmitting information about a terminal to be controlled based on a ratio of terminals having a throughput equal to or less than a predetermined threshold value in a cell, among the plurality of terminals, if the terminal to be controlled having a traffic usage exceeding a threshold value is identified, wherein the information includes an allocation and retention priority (ARP) value requested to be changed, and the ARP value requested to be changed is greater as traffic usage of the terminal to be controlled is greater. - View Dependent Claims (12)
