Abstract: A method of controlling congestion in a base station of a wireless communication system is provided. The method includes receiving a Service Data Unit (SDU) that includes pieces of data forwarded through a caching proxy, driving a timer each time an SDU is received for processing the SDU using a communication protocol, determining whether the SDU has been processed using the communication protocol until expiration of the timer, and controlling a transmission rate of the caching proxy based on a number of SDUs consecutively discarded or a number of SDUs consecutively transmitted depending on whether the timer has expired.

Abstract: A method for controlling data flow by a proxy server connected between a User Equipment (UE) and a content server is disclosed. The proxy server estimates a first amount of data reception indicating an amount of data received by the UE and calculates a second amount of data reception indicating an amount of data received by the proxy server from the content server. The proxy server delays transmission of acknowledgement (ACK) on data received by the proxy server from the content server and waits until a time allowed for the transmission, if the second amount of data reception is greater than the first amount of data reception by a predetermined threshold. The resent disclosure may prevent a waste of network load and unnecessary resources by the proxy server controlling download data rate from the content server.
