On account of the constant changing of location of mobile communication users, mobile location service will undoubtedly develop with a glorious perspective. At present most of the mobile location services are with the aid of SMS, which can only provide limited location services information. Based on the analyses of CDMAlX Ll Protocol, I design the mobile location service system based on WAP with the combination of location protocol and traditional GIS.This thesis will first provide an overall design of this system, and under the guidance of this, accomplish software programming. This system can answer the requirement of users' location and mail back users the corresponding geographic information in the form of pictures, totally replacing the limited location service which can only offer literal information. |
