Dynamic bandwidth allocation for multiple access communication using session queues

A method for allocating and deallocating channel resources from a limited number of channel resources used to transmit data from a base station transmitter within a network comprising a plurality of base station transmitters to a plurality of subscriber unit receivers, the method comprising the steps of:

• storing the data to be transmitted to a particular one of the subscriber unit receivers in a plurality of data queues, there being multiple queues associated with each receiver, and with each queue allocated to handle data traffic having a particular traffic type attribute, the individual queues associated with different transport layer sessions for a given user;
• accepting data at a transmit processor within the transmitter, the data arriving from the multiple queues for transmission to the particular receiver;
• allocating a number of channel resources to the particular receiver;
• and
• monitoring usage of each of the queues by a channel resource assignor to determine the urgency of data to be transmitted to each queue's respective receiver in order to dynamically assign an optimum number of channel resources to a communication link between the transmitter and receiver.
