A portable telephone system comprising first portable telephone terminal, second portable telephone terminal and a server for performing a management of position information of the first portable telephone terminal. The server is a relay server for position search service and registers into a password managing data base a password for allowing the second portable telephone terminal to search the position of the first portable telephone terminal in advance. The first portable telephone terminal notifies the password registered in the password managing data base to the second portable telephone terminal with a mail or the like. The second portable telephone terminal achieving the password transmits a position search request message to the server. The server checks the password indicated by the search request message, allows the position search and issues a search instructing message to the first portable telephone terminal.
Description
technical field [0001] The present invention relates to a portable telephone (eg, cellular telephone) system, and more particularly, to a portable telephone system including a portable terminal that can search for its own location or that of other terminals. Background technique [0002] There is known a portable telephone terminal (for example, a cellular phone) capable of searching its own position or the positions of other terminals by using a Global Positioning System (GPS) satellite or the like. In order to search for the location of another terminal, it is necessary to obtain a password from the side of the other terminal before searching. [0003] To generate a password, a combination of four digits is selected by the user of another terminal, and the password thus generated is then sent (told) only to individuals who are permitted to perform a location search. Transmission of passwords may be performed verbally or otherwise. The individual who has received the tran...
