RADIO BASE STATION

摘要

A radio base station BTS includes an upper limit value management unit 22 configured to determine and manage a upper limit value common to all mobile stations UE based on a bandwidth capable of being used for transmitting the uplink data in a wired section (Iub) between the radio base station and a radio network controller and a scheduling unit 23 configured to determine an Absolute Grant (AG) to be transmitted to a mobile station UE which is subjected to scheduling of the high-speed uplink communication so as not to exceed the upper limit value. The upper limit value management unit 22 is configured to decrease the upper limit value when a congestion signal in the wired section (Iub) is received for a predetermined number of times during a fit predetermined interval of time.
