Abstract: In order to solve the issue that existing model can not combine breakoff and integrity very well,a partially observable markov-modulated poisson process (PO-MMPP) traffic model was proposed.This model captures the burstiness of the overflow traffic under the imperfect observability of the network states.The optimal objective is the minimum network cost.It shows that the optimal control policy can balance the network cost and traffic QoS requirement.By derivation and confirmation,we induced the relations in call arrival rate and transition rates.Simulation results indicate that the proposed model provides better performance compared with complete sharing algorithm,in terms of minimizing the network cost,new call blocking and handoff call dropping probabilities.The network cost is reduced.The optimal control policy can be adaptive with network state and QoS requirement.
