<p><P>PROBLEM TO BE SOLVED: To locate the positions of all telephones by a telephony server. <P>SOLUTION: A network is divided into desired position units to be acquired for managing the positions of telephones by the telephony server, thus managing the positions without using any groupware. The telephony server can acquire information on a general telephone and a PHS, thus managing the positions of all telephones. In mobile access, setting for mobiles is required by the property of the network, thus acquiring position information without adding any sequences by adding the information to the message of a normal protocol with the telephony server, and hence eliminating the need for a user to register a schedule. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
