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.

摘要： 探究了移动网络数据业务的服务保障机制，结合ATM网络自身的特点分析了为保证商定的QoS协议网络各层所需要提供的功能，设计出QoS的协商、修改，以及用户切换网络后的重协商过程。对系统信令流程和各种数据业务的QoS特性进行了测试，证明了方法的有效性。
