Abstract
A network call admission control system receives a call and determines a call characteristic requirement and a network characteristic parameter. The call is admitted to the network based in part on whether the call characteristic requirement is satisfied by the network characteristic parameter. As a result, a communications service provider can provide a high quality of service for completed calls or charge a discounted rate for completed calls not meeting a certain quality of service.
Claims20
A method for regulating the admission of a call to a packet-switched network, comprising:
- determining a delay characteristic requirement of the call, said requirement including a typical delay requirement and a delay variation requirement;
- determining a delay characteristic parameter of the packet-switched network, said parameter including a typical delay parameter and a delay variation parameter;
- and
- holding the call if the determined delay characteristic parameter does not satisfy the determined delay characteristic requirement.
A system for regulating the admission of a call to a packet-switched network, comprising:
- means for determining a delay characteristic requirement of the call, the requirement including a typical delay requirement and a delay variation requirement;
- means for determining a delay characteristic parameter of the packet-switched network, the parameter including a typical delay parameter and a delay variation parameter;
- and
- means for holding the call for a predetermined amount of time if the determined delay characteristic parameter does not satisfy the determined delay characteristic requirement.
An apparatus for controlling the admission of a call into a packet-switched network, comprising:
- a processor;
- and
- a memory, coupled to said processor, storing a plurality of instructions adapted for execution by said processor to:
- determine a delay characteristic requirement of the call, said requirement including a typical delay requirement and a delay variation requirement;
- determine a delay characteristic parameter of the packet-switched network, said parameter including a typical delay parameter and a delay variation parameter;
- and
- hold the call for a predetermined period of time if the determined delay characteristic parameter does not satisfy the determined delay characteristic requirement.
