a system information transmission unit which transmits the system information read out from the user database to the communication device as a request source;
a judgment unit which judges if the communication device has been connected via the communication network for a predetermined period of time, generates a judgment signal indicating that the communication device has been connected for the predetermined period of time; and
a re-transmission instruction unit which sends a re-transmission instruction of the download request of the system information to the communication device in response to the judgment signal, and the communication device comprising;
a request transmission unit which transmits the download request of the system information to the main apparatus;
a system information reception unit which receives system information that comes from the main apparatus via the communication network in response to the download request; and

Abstract
Upon providing the same functions as those of telephone terminals in a telephone system to a mobile communication terminal outside the telephone system, the mobile communication terminal transmits a download request of system information to a main apparatus in the telephone system. This download request contains an user ID and a telephone number of the mobile communication terminal. The main apparatus compares the user ID contained in the download request with those stored and managed in the user database so as to check user'"'"'s authenticity. The main apparatus then accesses the mobile communication terminal via a public network on the basis of the telephone number, and transmits the requested system information, thus providing the same functions as those of the telephone terminals.
