摘要
位置服务(LBS)主要使用移动用户的位置信息来提供增值。围绕IP多媒体子系统(IMS)基本服务可以开发大量位置应用,这些应用除了涉及到位置信息的处理外,还很大程度上涉及到对呈现信息的处理。经分析发现位置信息也可作为呈现信息的一种类型,因此在重用IMS呈现服务主要处理机制的基础之上,提出了一种基于呈现的位置服务的体系架构,从而使现有呈现服务能平滑地适应位置信息的处理。
Location-Based Services（LBS） provide added-value mainly by using the location data of mobile users.With existing and emerging IMS services involved in handling location data and presence information,a wide range of location applications could be developed.Analysis indicates that the location data could be regarded as a type of presence information,and thus an architecture which reuses large part of IMS presence infrastructure is proposed by applying presence mechanisms to the location data.
