中文摘要：

针对当前市场上推出的MLS系统独立、封闭的现状，提出了一种基于开放标准的MLS系统设计方案：采用客户／服务器的架构方式．客户端设备支持java的MIDP技术，服务器端采用的是Webservices，开发语言用java，这样整个系统的搭建就不会受平台的限制．对于来源于不同物理位置或不同存储格式的地理信息数据，其在服务器端内的传输采用的是GML语言；通过XSLT，GML文件中描述的地理信息数据可以转换为能受移动设备控制的矢量图形描述语言SVG，它们都是基于开放XML语言标准，文中还就其关键技术的实现方法加以说明.

英文摘要：

Through analysis of the status of the MLS System on the market, this paper proposes a MLS system design scheme based on open standard. It follows a client/server architecture, the client uses Java Mobile Information Device Profile technology, the server uses Web services developed by java language, thus the system is independent of the platform. On the server side, the geographic information from different physical location or different format is transmitted by GML. Using XSLT, GML is transformed to a graphical format in Scalable Vector Graphics （SVG） which can then be manipulated in the mobile device. Both of them are based on the open standard＇s XML. Also the paper explains the key technology of the scheme.
