Mobile station, downstream transmission rate control method, and downstream transmission rate control program

摘要

An aspect of the invention provides a mobile station which can restrict an upper limit of a transmission rate according to a processing capacity in processing packet data received from a base station. The mobile station includes packet data retaining means 16 for tentatively retaining packet data received from a base station 100; reject ratio computation means 16 for computing a ratio of rejected packet data in the packet data retained by the packet data retaining means 16; transmission rate setting means 30 for setting an upper limit of a downstream transmission rate based on the ratio computed by the reject ratio computation means 16; and transmission rate notification means 25 for notifying the base station 100 of the upper limit of the transmission rate set by the transmission rate setting means 30.
