普适服务综述

随着技术和市场的发展，电信网和互联网正在走向融合，形成一体化网络，提供的服务也将逐步趋同。普适服务融合了各方面对未来服务的需求和期望，成为超3G、下一代网络（NGN）、下二代互联网（NGI）等研究领域的热点问题。普适服务的概念起源于普适计算和超3G领域，其特征包括普适性、移动性、透明性、质量可控性、个性化、自适应性、主动性、安全性、易用性、多样性、快捷性。3GPP、OMA等标准化组织以及欧盟的超3G研究项目都针对普适服务的不同特征进行了研究。当前普适服务的研究热点包括上下文感知、业务使能等技术。

A Survey of the Pervasive Service

As technology and market develop, telecommunications networks and the Internet are gradually converging into a universal network, and they tend to provide the same kind of services as well. The pervasive service integrates the requirements and perspectives for the future service from all aspects, and becomes a hotspot in fields such as B3G, Next Generation Network (NGN), and Next Generation Internet (NGI). The concept of pervasive service is derived from the fields of pervasive computing and B3G. Its features include pervasiveness, mobility, transparency, quality-guarantee, customization, adaptiveness, dynamism, security, easiness, variety, and fast time-to-market. 3GPP, OMA and the B3G research programs of the European Commission did a lot of research work about the different features of pervasive service. The hotspots in the field of pervasive service include context-awareness, service enabling, and more.
