摘要
A method of adaptively resolving contentions in a digital communication system is provided. A headend, such as a Base station Transceiver System, transmits a Media Access Control message to Customer Premise Equipment units. The Media Access Control message includes information on the current load on shared transmission resources. The Customer Premise Equipment units implement a truncated binary exponential back-off algorithm for requests. However if the current load on the transmission resources is low enough, the Customer Premise Equipment units reduce the back-off times of backlogged requests to allow them to take advantage of the low load. The headend may also maintain a table of service flows and their levels of activity. If the level of activity at shared transmission resources falls below a threshold, the headend determines from the table which service flows are likely to have backlogged requests. The headend transmits a unicast-type signal identifying the service flow, and the Customer Premise Equipment unit managing the identified service flow transmits the backlogged request.
