文摘A multimedia channel allocation scheme is proposed and studied in terms of the connection-level QoS.A new traffic model based on multidimensional Markov chain is developed considering the traffic characteristic of two special periods of time.And the pre-emptive priority strategies are used to classify real-time services and non-real-time services.Real-time service is given higher priority for its allowance to pre-empt channels used by non-real-time service.Considering the mobility of persons in a day,which affects the mobile user's density,the simulation was conducted involving the two pre-emptive priority strategies.The result of some comparisons shows the feasibility of the proposed scheme.
