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.
Claims44
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.
A method for scheduling resources in a wireless communication system supporting packet data application flows, the method comprising:
- selecting at least one compensation factor for a quality of service parameter associated with an application flow,
- calculating the at least one compensation factor based on a the quality of service parameter;
- calculating a weight for the application flow as a function of the at least one compensation factor;
- calculating a scheduling factor using the weight;
- and
- scheduling the application flow based on the scheduling factor.
An Access Network (AN) apparatus in a wireless communication system supporting application flows having various quality of service requirements, the apparatus comprising:
- application flow processing unit adapted to receive packets of an application flow and process the packets for transmission to an Access Terminal (AT);
- quality of service monitoring unit adapted to receive the packets of the application flow and evaluate quality of service requirements for the application flow;
- adaptive weight calculation unit adapted to generate an adaptive weight for the application flow according to evaluation of the quality of service requirements for the application flow;
- and
- scheduling unit adapted to schedule transmissions of the application flow by applying the adaptive weight.
An apparatus for 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 apparatus comprising:
- means for assigning an initial weight for each of the plurality of ATs;
- means for 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;
- means for calculating a ratio of requested data rate to throughput;
- means for applying the adaptive weight value to the ratio to result in an adapted ratio;
- and
- means for selecting an application flow based on the adapted ratio, wherein the selected application flow is to be served by the AN.
