移动通信和无线技术的进步需要在日常生活中提供本地但熟悉的服务，而这并不是通过互联网上的全球服务来满足的。在不断变化的市场下的零售业务中，用户根据自己的偏好和情况要求获得未知但合适的服务，零售商需要了解当地特定贸易领域大多数消费者的当前需求。由于用户在其贸易领域的需求的瞬时性，服务要求是临时性的和有时间限制的。因此，服务的领域需要随着时间的推移而变得更加狭窄。为了同时满足用户和零售商的需求，提出了服务型社区的概念。它是由特定领域内的成员以服务为基础，相互合作，实现互利共赢。为了实现面向服务的社区，系统需要灵活性来有效地提供服务，并需要容错来保证稳定的服务。在面向服务的社区系统中，时间距离被引入作为衡量用户与零售商之间距离的有效度量。面向时间距离的服务体系结构就是为了满足这些灵活、稳定的服务需求而提出的，节点根据时间距离自主分配服务，缩小服务范围。为了满足高服务可用性的需求，本文提出了一种自主协作的容错技术。
The advancement of mobile telecommunication and wireless technologies is required to provide local but familiar services in daily life, which has not been satisfied through the global services on the Internet. In retail business under evolving market, users request access to unknown but appropriate services based on their preference and situation, and retailers need to be aware of the current requirements of the majority of consumers in specific local trade areas. Because of the transience of the requirements of the users in their trade-areas, the services require being temporary and having the time limit. Therefore the areas of the services need to become narrower with the time. The concept of the service oriented community has been proposed to satisfy both the users and the retailers requirements. It consists of members in the specified area based on services, and they cooperate with each other in order to get mutual benefits. For realization of the service oriented community, the systems require flexibility for the effective provision of the services and fault tolerance for the stable service. In the service oriented community system, the Time Distance has been introduced as the efficient measure of the distance between the users and the retailers. The Time Distance Oriented Service System architecture has been proposed to satisfy these requirements for flexible and stable services, where the nodes are autonomously distribute services and reduce the service area based on the time distance. Here autonomous cooperation technique for achieving fault tolerance is proposed in order to satisfy the requirement of high service availability.
