Abstract: A method of registering an IP (Internet Protocol) terminal device including a function to transmit and receive IP packets, to a line-switching exchanger including a database that is used for managing a type and a telephone number of a telephone set is provided. The method includes the steps of connecting the line-switching exchanger and a network-gateway device by use of a radio-base-station-connection line that is used for connecting radio base stations, connecting the network-gateway device and the IP terminal device through an IP network, and registering the IP terminal device as a radiotelephony device in the database. By registering the IP terminal device as a radiotelephony device in the database provided in the line-switching exchanger, the IP terminal device can receive a variety of supplementary services provided by the line-switching exchanger since the IP terminal device is defined as a radiotelephony device, for example, a PHS phone, by the line-switching exchanger.
