摘要
综述了第三代移动通信系统对QoS的要求及其结构。详细介绍了UMTS系统的QoS分类、结构特性及各分类的性能要求和应用。针对UMTS网络需要考虑的一些问题,提出了现有异种网络之间QoS机制的互操作性及各协议如何互相操作,以弥补各自的不足,从而使QoS结构更加完善。
In this paper,firstly we introduced the overviewof QoS in the third generation mobile telecommunicationsystem including requirements for QoS and QoS architecture.Secondly this paper promotes the QoS classes, the specificstructure, the capability target and application of each Class.There are many problems which need us to have a condition.In order to sustain the mutual operation of the QoS mechanismamong different nets, in the end we also state the mutualoperation of each protocol. Then we can compensate therespective insufficiency and make the QoS structure moreperfect.
