A call admission control mechanism using MPP and 2-tier cell structure for mobile multimedia computing

A call admission control mechanism is proposed to provide a consistent QoS guarantee for multimedia traffic on a mobile computing environment. An adaptive bandwidth reservation based on an MPP(mobility pattern profile) and a 2-tier cell structure is proposed to determine the amount of bandwidth to be reserved in the cell and to control dynamically its amount according to network conditions. We also propose a call admission control based on this bandwidth reservation and "next-cell prediction" scheme using an MPP.
