Seamless mobility management of users and services over heterogeneous networks

计算机技术已经成为日常生活中不可或缺的一部分，影响着个人、家庭、学校和各种组织。预计计算机将在未来获得更大的存在并发挥更关键的作用。在通信和网络方面将取得重大技术进步。重点将放在移动和无线连接上，即所谓的第三代(3G和即将到来的4G)移动电信系统，在一定程度上还将集中在临时网络上。这种环境处理的是“多分区网络”中的通信，其中人员、设备、设备和服务器通过不同类型的网络相互连接。网络将是无处不在、无处不在、多业务、多运营商和多接入的。它们将把几种不同类型的网络结合在一起，例如身体区域网络、车载区域网络、个人区域网络、家庭区域网络、无线热点网络和蜂窝网络等等。目前，随时访问和使用这些网络提供的服务很麻烦，在某些情况下不切实际或负担不起。我们认为，3/4G移动系统的成功在于能够随时随地为移动用户提供经济高效、但无处不在的服务接入。为了做到这一点，这种系统必须根据网络配置和用户需求的要求进行个性化、适应性、主动性和预见性。该项目的目标是开发、演示和评估移动服务交付架构和框架，以支持移动通信系统中的无缝服务和用户移动性运营和管理。我们设想，这样一个环境将由关键的集成技术组件组成，这些组件将为用户和服务提供处理移动性管理和功能的能力，这些功能是动态和自适应的，基于环境、首选项、网络、成本、服务质量，所有这些都与组织和个人的策略平衡。

Computer technologies have become an essential part of daily life, influencing individuals, families, schools and organizations of all kinds. Computers are expected to gain an even greater presence and play an even more critical role in the future. Important technological advances will be made in communications and networks. The focus will be on mobile and wireless connectivity, known as third generation (3G and coming 4G) mobile telecommunications systems, and to a certain extent on ad hoc networks. This environment deals with communication in "multi-zoned networks", where people, devices, appliances and servers are connected to each other via different kinds of networks. Networks will be pervasive, ubiquitous, multi-service, multi-operator and multi-access. They will bring together several different types of networks, such as body area networks, vehicular area networks, personal area networks, home area networks wireless hotspot networks, and cellular networks among many others. Currently accessing and using the services provided by these networks at any time is cumbersome and in some cases impractical or unaffordable. We believe that the success of 3/4G mobile systems lies in the ability to provide mobile users with cost effective, yet ubiquitous service access anywhere and anytime. In order to do this, such systems will have to be personalized, adaptive, proactive and anticipatory in the requirements of network configuration and user needs. The goal of this project is to develop, demonstrate and evaluate a mobile service delivery architecture and framework to support seamless service and user mobility operations and management in mobile communication systems. We envision such an environment to be composed of key integrated technological components that will provide users and services the ability to handle mobility management and functions that are dynamic and adaptive, based upon context, preferences, networks, cost, QoS, all balanced with policies of organizations and individuals.
