Abstract: The mechanism to guarantee the QoS on UT network is proposed, it focuses on the realization of end-to-end QoS framework. In the framework, function of protocol on each layer is discussed, and the characteristics of ATM network is also considered. Such work processes as the negotiation of QoS, the modification of QoS and the renegotiation of QoS when users perform inter-region handover are described. The result is presented by test work process and the QoS of services.

Key words: Mobile communication, Network performance, Quality of Service(QoS)
