Patent ID: RE43593

Claim:
A base station for allocating radio resources to a first mobile station, which transmits real time packets and non-real time packets, and a second mobile station, which transmits the non-real time packets, the base station, comprising: an acquisition unit configured to acquire, from the first mobile station, a value indicating a quantity of stored real time packets to be transmitted by the first mobile station, the real time packets being stored in a buffer for storing the real time packets at the first mobile station; a radio resource controller configured to allocate priority radio resources, which indicate a maximum quantity of radio resources necessary to transmit the real time packets, to the first mobile station on a radio channel, and to allocate, to the first mobile station, usable radio resources to be used by the first mobile station for transmitting the real time packets, within the allocated priority radio resources, based on the value acquired by the acquisition unit; and a result notification unit configured to report the usable radio resources allocated by the radio resource controller to the first mobile station, wherein a quantity of the radio resources necessary to transmit the real time packets are varied, a priority of the non-real time packets are lower than a priority of the real time packets, and the radio resources, which are not allocated as the usable radio resources within the priority radio resources, are used for transmitting the non-real time packets by the first mobile station or the second mobile station.
