METHOD AND SYSTEM FOR PERCEPTUAL QUALITY OF SERVICE BASED CALL ADMISSION CONTROL AND CALLBACK

摘要

A system of perceptual quality of service (PQoS) based call admission control in a communications network includes a mobile communications terminal, which transmits a connection request, and a network node, which makes a call admission control decision based on a comparison between a required PQoS value and a resource availability measure. A method for PQoS based call admission control in a communications network includes checking a resource availability in the communications network, comparing a required PQoS of the mobile communications terminal to a resource availability measure and making a call admission control decision based upon the comparison. A network node, or server, determines whether there are sufficient network resources available to complete the call. If sufficient network services are not available, the user is given the option of a callback to complete the call within a time-out period based on probability of resource availability.
