Patent ID: 7460474

Claim:
A packet transmission control apparatus which performs transmission control of packets to a plurality of mobile stations, comprising: an acquirer configured to acquire an average transmission rate of packets to each of the plurality of mobile stations and a guaranteed transmission rate of the packets; and a scheduler configured to perform scheduling to transmit packets to a specific mobile station preferentially, when an average transmission rate of the packets to the specific mobile station approaches the guaranteed transmission rate, wherein the acquirer is configured to acquire the average transmission rate Rn of the packets to the mobile station #n, the guaranteed transmission rate R n target , a radio condition R n between the packet transmission control apparatus and the mobile station #n, and predetermined parameters α and β, and the scheduler is configured to select a mobile station #n to which packets are transmitted based upon a relationship between Rn α and ( Rn −Rn target ) β , wherein α and β are within a range 0≦α,β≦1.
