In the 3G mobile communication systems, the services consist of symmetric services such as voice service and asymmetric services such as WWW browsing. The TDD mode CDMA systems can adapt itself well to time varying asymmetric traffic. In this paper, a new dynamic channel allocation (DCA) model based on Markov decision programming (MDP) has been established to dynamically adapt the switching point in the TDD radio frame according to the states of the system. Simulation results have shown that it will decrease the system blocking rate and increase the resource usage compared with the fixed channel allocation (FCA) scheme.
