Resource allocation in a communication system supporting application flows having quality of service requirements
First Claim
1. A method of allocating a resources 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 method comprising the steps of:
- assigning an initial weight for each of the plurality of ATs;
adapting the initial weight to form an adaptive weight value as a function of a Quality of Service profile for each application flow active for each of the plurality of ATs;
calculating a ratio of requested data rate to throughput;
applying the adaptive weight value to the ratio to result in an adapted ratio; and
selecting an application flow based on the adapted ratio, wherein the selected application flow is to be served by the AN.

Abstract
A method and apparatus for allocating and using a resource to transmit wireless information signals to a plurality of subscriber units wherein application flows are selected based on associated Quality of Service (QoS) requirements. Compensation factors are evaluated for a plurality of QoS requirements. For a violation of a given QoS requirement, the corresponding compensation factor is calculated and applied to an adaptive weight, else the compensation factor is set to a default value.
