Abstract:
1. A method for admission control in a communication system supporting Internet Protocol (IP) applications, the communication system including an Access Network (AN) and a plurality of Access Terminals (ATs), each of the ATs sending a requested data rate to the AN, the communication system supporting application flows having QoS requirements to the ATs, the method comprising: determining available resources in the communication system; receiving a request for a first application flow having a first traffic profile and a first QoS profile; determining if the available resources support the request for the first application flow; denying the first application flow if the first application flow has a corresponding data rate greater than an average requested data rate; and admitting the first application flow if the corresponding data rate is not greater than the average requested data rate, and if the available resources support the request for the first application flow, wherein the method further comprises: determining QoS statistics for the first application flow; comparing the QoS statistics for the first application flow to other current flows in the sector; and updating the available resources and reserved resources in response to comparing the QoS statistics for the first application flow to other current flows in the sector.
