| 摘 要： | 结合手机定位与数字地图传送功能,对J2ME开发平台下基于手机定位实现便携式移动导航系统进行了研究,提出了可行的解决实现方案。利用手机提供的基于位置服务功能LBS(Location Based Server),通过无线通信网络传送用户所在区域的数字地图,为用户提供定位、导航、服务等多种相关的信息。整个系统由无线移动终端、数字地图服务器、网关3部分组成,通过在手机中内嵌J2ME-MIDP,让手机端可以提供更新准确的定位服务,地图服务器和网关建立在传统的以太网络上,可以有效地减少网络通信的时间,降低系统复杂度。实验中以浙江大学校园地图为例,结合WAP Push技术和手机定位功能,成功地实现了手机导航的功能。

| Abstract: | With the popularization of mobile communications in recent years,Location Based Service(LBS) have become the popular subject of research.In this paper,Mobile Geographic Information System(MGIS) is designed based on mobile location and digital map transfer.This system consists of three parts,that is,mobile equipment,map service center and gateway mobile location center.It utilizes the location server of the cellular mobile communication system,and Internet is regarded as the medium for information exchange to provide users with the maps around users.Java's cell-phone is chosen as the target mobile equipment.This system follows the mobile location protocol.In the experiments,the mobile map service is implemented with map database of Zhejiang University area as an example.Through WAP Push technology the user can get the map and campus navigation can be offered successfully. |
