中文摘要：

为了有效访问基于位置服务（LBS）环境中的服务信息,提出了基于移动agent和元数据的LBS信息查询新思路,给出了构建LBS信息查询系统的方法,并利用移动agent开发平台Voyager和Java系列软件开发了一个分布式的LBS信息查询系统,实现了在LBS系统中信息的透明访问。

英文摘要：

This paper proposed a new idea based on mobile agent and metadata to query information efficiently in locationbased service （ simply LBS） environment, which could overcome the drawbacks of the traditional connection-based access method. And provided an approach to building LBS query system and developed an information query system in distributed LBS environment based on Java softwares, and on Voyager, a free mobile agent development platform. Experimental results show that information can be accessed transparently in LBS system.
