当前移动通信网络的日益使用导致了对新的和更强大的系统的定义，这些系统将具有更多的用户服务。新业务的加入会带来不同的需求，使得整体的服务质量管理成为一项复杂的任务。建模技术对于评估必须做出的技术选择以及帮助设计、规划和全面管理网络非常有用。不幸的是，当前的建模技术没有考虑到新需求的丰富性，必须应用新的模型。本文对现有的一些最相关的建模技术在面对新的需求时的局限性进行了综述。为了更好地描述下一代无线网络，本文确定了新模型必须具备的主要特征。概述了一些可能的方法。
The growing usage of the current mobile communication networks is leading to the definition of new and more powerful systems which will have a larger number of user services. The addition of new services will impose different requirements making the overall QoS management a complex task. Modeling techniques can be valuable to assess the technological choices that have to be made and to help in the design, planning and overall management of the network. Unfortunately, current modeling techniques do not take into consideration the richness of the new requirements and new models have to be applied. This paper makes a survey on the limitations of some of the most relevant existing modeling techniques in face of the new requirements. The paper identifies the main characteristics that the new models must have to better describe the next generation wireless networks. Some possible approaches are outlined.
