Abstract: PURPOSE: A service system using a mobile terminal is provided to enable a user to transmit site information to a GIS server, if data of the GIS(Geographical Information System) server are different from information contents inside a PDA(Personal Digital Assistant). CONSTITUTION: A user connects a CDMA(Code Division Multiple Access) wireless data communication network by using a CDMA module arranged in a PDA(S10), and requests a desiring service to a host computer(S11). The PDA searches a Web server, which is the host computer, and a GIS data server(S12) to request the service(S13). The servers provide a proxy for a corresponding information server to the PDA(S14). The PDA calls the corresponding information server, e.g. the GIS data server(S15) to request desired information(S16). The GIS data server transmits the requested information to the PDA through a gateway, a DSU(Digital Service Unit), and the CDMA wireless data communication network(S17). The PDA displays the received information on a display window(S18). The user checks whether the displayed information is coincident with site information checked by himself/herself(S19). If so, the steps are ended, and if not coincident, the user corrects the received information by referring to the site information(S20), to transmit the corrected information to a host system through the CDMA wireless data communication network(S21). And a manager of the host system confirms the transmitted information and updates the information stored in the GIS data server and a storage unit(S22).
