SYSTEM FOR CONTROLLING CONGESTION OF MOBILE COMMUNICATION NETWORK HAVING BASE STATION AND RADO NETWORK CONTROLLER, AND METHOD THEREFOR

摘要

A system and a method for controlling congestion of a mobile communication network having a base station and an RNC(Radio Network Controller) are provided to improve a congestion control algorithm by determining a priority level according to an amount of non-real time data, and differentially reducing a transmission rate according to the priority level when there are multiple non-real time data. A base station(102) includes a load measuring unit(110) for measuring a load of total power transmitted to a terminal. An RNC(104) interworks with the base station through a mobile communication network. A storage unit(120) previously set and store a threshold value with respect to the load measured by the load measuring unit. A comparing unit(130) compares the threshold value and the measured load value. A controller(140) controls a transmission rate according to each priority level of real time transmission data and non-real time transmission data.
