Abstract In this paper a novel dynamic channel allocation algorithm based on network optimization in CDMA network is presented. It establishes an integer programming model for CBR services, which does not allocate channel at each time slot but at some time slots. The goal is to trade off between the QoS for users and system performance. The simulation results show that this optimal algorithm both improves the channel usage and guarantees the QoS, compared with traditional voice-allocated-first algorithm and queue-by-priority allocation algorithm.
