Patent ID: 7710977

Claim:
A method for allocating radio resources to a plurality of packets addressed to a plurality of wireless terminals located in an area covered by a base station, comprising the steps of: setting a threshold of buffering delay of the packets at the base station based on required service qualities of the wireless terminals; monitoring and determining communication qualities of the wireless terminals; setting quality ranges for buffered packets based on the monitored communication qualities; classifying the packets addressed to the wireless terminals into two or more groups based on the determined communication qualities of the wireless terminals and the quality ranges; measuring buffering delay of a leading one of the packets in each of the groups; comparing the buffering delay of the leading one of the packets in each of the groups with the threshold; and if the buffering delay of the leading one of the packets in one of the groups is at or above the threshold, giving priority for allocating the radio resources to the packets in said one of the groups.
