Considering the real time transmission and impartial service of information packets for Broadband Wireless Access(BWA) network systems,a novel and efficient model of two-level-polling system based on priority service was presented.The system consisted of a hub station and N common stations,providing exhaustive service and limited service(K=1) in discrete time respectively.By the embedded Markov chain theory and the probability generating function methodology,the closed form expressions for obtain-ing the characteristic parameters of the system were given,and the analytical results verified by extensive computer simulations.The performance results reveal that this new scheme has high performance in better impartiality and real time transmission of information packets for BWA.
