Service engineering in post 3G telecommunications networks

3G网络(UMTS、CDMA2000、PackCable)以及相关业务架构的部署才刚刚开始。研究现已转向后3G网络。然而，在相关的服务体系结构方面所做的工作很少。这项研究计划致力于4G的服务架构。在提案中，我们使用世界无线研究论坛(WWRF)对4G(即共存/合作的传统网络和新网络)的定义。一方面，我们使用3G网络作为传统网络的用例。另一方面，我们使用移动自组织网络(MANET)和无线传感器网络(WSN)作为新网络的用例。研究了在独立的MANET、独立的WSNs和集成的3G/MANET/WSNs/中创建、部署、使用和撤销终端用户应用/服务的体系结构。提出并验证了系统的功能实体、算法和接口。采用数学分析、原型制作和仿真等方法进行验证和性能评估。这些体系结构依赖于一整套技术，如上下文感知、集群、覆盖网络、点对点和移动代理。这些技术得到了最大限度的利用。此外，只要有必要，我们就会研究如何扩展它们。

The deployment of 3G networks (UMTS, CDMA 2000, PackCable) along with the related service architectures has just started. Research has now shifted to post 3G networks. However, very little is being done on the related service architectures. This proposed research program is devoted to the service architectures for 4G. In the proposal we use the world wireless research forum (WWRF) definition of 4G (i.e. co-existing/co-operating legacy and new networks. On the one hand we use 3G networks as use cases for legacy networks. On the other hand we use mobile ad hoc networks (MANETs) and wireless sensor networks (WSNs) as use cases for new networks. Architectures for creating, deploying, using and withdrawing end-user applications/services in stand alone MANETs, stand alone WSNs, and integrated 3G/MANETs/WSNs/ are investigated. Functional entities, algorithms and interfaces are proposed and validated. Mathematical analysis, prototyping, and simulation are used for validation and performance evaluation. The architectures rely on a panoply of technologies such as context awareness, clustering, overlay networks, peer to peer and mobile agents. These technologies are exploited to the fullest possible extent. Furthermore, whenever necessary, we investigate how to extend them.
