By introducing the demand of user and pricing model for multi-class quality of service stochastic network systems,discusses the problems of pricing strategy,and gives the agonic estimate of demand of consumers.Designs static and pricing strategy for the system that the call-arriving time of a call is a geometric distribution,and designs the dynamic pricing strategy,which is applicable to the complex systems.The average demand estimates are adjustable by the dynamic pricing strategy in order to make the profit of the networks system maximizing.Because the demand is stochastic,the incentive pricing control strategy is given to encourage and guide the non-cooperative users to select the serving request, which is helpful to the network system.The given pricing strategies will be benefit to increase the rate of network resource using,to control congestion of network,the need of increasingly develop of network.
