Access Control Scheme based on Preemption for Integrated Video/Data CDMA Systems

Abstract

The third-generation mobile communication system is being developed to support to a wide range of services with different bit rates such as data, video as well as voice. We propose an access control scheme based on preemption policy to provide efficiently high priority video services and low priority data services. We analyze the proposed scheme using Markov model and present the performance evaluation of video service and data service in view of video packet dropping probability and data message delay.
