Optimal call access control for DS-CDMA cellular networks

A novel access control strategy for cellular DS-CDMA networks is proposed within the framework of Markov Decision Processes. This paper considers the scenario where users in the network are partitioned into two groups, realtime and non-realtime; and only non-realtime users may be “access controlled” as they are more delay tolerant. The transmission rate of non-realtime users are then regulated via time-division multiplexing to satisfy the QoS requirements. The ACS proposed is optimal because it maximises the transmission rate of non-realtime users while ensuring that QoS requirement of all users are satisfied.
