网络运营商、服务提供商和客户是具有不同利益的参与者，对未来移动通信网络的功能提出了不同的要求。然而，一些新的能力，如移动性、安全性、普遍性和质量，是大家都阐明的，这意味着存在一些实际上每个网络都需要的基本机制。本文重点讨论在提供服务之前需要在 4G 网络中部署的网络基础设施的关键要素。在本文中，我们讨论了这些元素，并展示了如何将它们组合起来以满足多样化的服务需求。此外，本文还展示了如何将三种传统上完全独立的架构的机制结合起来：身份验证、授权、计费和计费 (AAAC)、移动性（具有快速切换的移动 IP）和服务质量 (QoS)。该系统还集成了独立于技术的寻呼概念。由此产生的集成系统架构是通用的，可以部署在异构环境中。我们的实施最近已完成，并通过数据传输、IP 语音、视频流和实时并发游戏等应用程序进行验证和验证。该原型实现结合了 TD-CDMA、802.11 WLAN 和以太网，并将所有传输技术视为物理层和数据链路层，同时通过基于全 IPv6 的信令以统一方式支持更高级别的功能。
Network operators, service providers and customers are players who have different interests and raise different requirements on the functionality of future mobile communication networks. However, some new capabilities, such as mobility, security, ubiquity and quality are spelled out by all, which means that there exist some fundamental mechanisms which are in fact needed in every network. This paper concentrates on critical elements of the network infrastructure which need to be deployed in 4G networks before services can be offered. In the paper we discuss these elements, and show how they can be combined to satisfy versatile service requirements. Furthermore, the paper shows how to combine these mechanisms of three traditionally quite separate architectures-for Authentication, Authorisation, Accounting and Charging (AAAC), for Mobility (Mobile IP with Fast Handover), and Quality-of-Service (QoS). A technology-independent paging concept is also integrated in this system. The resulting integrated system architecture is general and can be deployed in heterogeneous environments. Our implementation has recently been completed, validated and verified with applications such as data transfer, voice-over-IP, video streaming and real time concurrent gaming. This prototypical implementation incorporates TD-CDMA, 802.11 WLANs and Ethernet, and treats all transmission technologies as physical and data-link layers, while higher-level functions are supported in a uniform way with an all-IPv6-based signalling.
