基于OSGi的LBS终端系统

LBS TERMINAL SYSTEM BASED ON OSGi

简要介绍LBS的概念与发展情况,提出研究项目,即一个能提供位置服务的移动终端系统;简单介绍OSGi规范以及这个规范的优点;之后叙述此终端系统的位置更新策略;探讨这个移动终端系统的设计与一些实现的细节问题;介绍系统的工作流程;最后说明实验结果并进行总结,得出进一步学习OSGi的必要性。

First,the concept and development of LBS is briefly introduced,following it,the project to be studied in this paper is presented,it is a mobile terminal system which can provide location services;then the OSGi specification and the advantages of it are introduced in brief;Afterwards the location update strategy of terminal system is recounted;and then is the discussion on the design of the mobile terminal system as well as some details in its implementation;Furthermore,the workflow of the system is introduced;Finally,the experimental results are depicted together with the summarisation,from it the necessity of further studying OSGi is derived.
