Radio base station device, radio network control device, and transfer rate decision method

摘要

A radio base station apparatus in a communication system in which best effort type transmission is carried out between the radio base station apparatus and mobile terminal apparatus through a wireless channel, capable of reducing a wait time in a buffer. The radio base station apparatus ( 300 ) is provided with a determining section ( 308 ) that determines a transfer rate of data transferred from a radio network control apparatus ( 500 ), a storage section ( 304 ) that temporarily stores data transferred from the radio network control apparatus at the transfer rate, a transmission section ( 301 ) that transmits the data stored in the storage section to a mobile terminal apparatus by radio, a wait time measuring section ( 306 ) that measures a wait time of data in the storage section and a transmission rate calculation section ( 307 ) that calculates an average transmission rate of data transmitted by radio to the mobile terminal apparatus, wherein the determining section ( 308 ) regards a value obtained by multiplying the average transmission rate by a coefficient according to the wait time as the transfer rate.
