Abstract

PURPOSE: To allow the exchange to conduct exchange and connection between a PHS(Personal Handy Phone System) and a telephone line by adding a simple adaptor means to an existing private branch of exchange in the personal portable telephone system such as PHS. CONSTITUTION: For example, suppose that a dial-in signal equivalent to a portable terminal 4 is received from a public telephone line 6. When an adaptor 11 detects a corresponding number in response to a line 6, at first a private branch of exchange 1 is started and sends automatically a dial number corresponding to a base station connection terminal 9. Since the private branch of exchange 1 connects the adaptor 11 to an adaptor 13 via the base station connection terminal 9, the adaptor 11 sends a number corresponding to a portable terminal 4 to the adaptor 13 by an inband signal. The adaptor 13 receiving the in-band signal converts the number into a signal system suitable for the base station 3 and transfers the converted signal to the base station 3, and the base station 3 calls the portable terminal 4 via a radio channel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a private branch exchange, 3 is a base station, 4 is a mobile terminal, 5 is an extension telephone, 6 is a public telephone line connection terminal, 7 is an extension telephone line connection terminal, and 9 is a base station connection terminal. , 11 is an adapter connected to the connection terminal 6 of the public telephone line, 12 is an adapter connected to the connection terminal 7 of the extension telephone line, and 13 is an adapter connected to the base station connection terminal 9. For example, assume that a dial-in signal corresponding to the mobile terminal 4 is received from the public telephone line 6. When the adapter 11 responds to the public telephone line and detects the number of the mobile terminal, it first activates the private branch exchange 1 to automatically transmit the dial number corresponding to the base station connection terminal 9. After the private branch exchange 1 connects the adapter 11 to the adapter 13 through the base station connection terminal 9, the adapter 11 sends the number corresponding to the mobile terminal 4 to the adapter 13 by an in-band signal. The adapter 13 receiving the in-band signal converts this number into a signal system suitable for the base station 3 and transfers it, and the base station 3 calls the mobile terminal 4 through a wireless line. Similarly, when the extension telephone 5 sends a dial number corresponding to the mobile terminal 4, the adapter 12 connects the line and detects the number, and first activates the private branch exchange 1 to correspond to the base station connection terminal 9. Automatically dial the dialed number. The private branch exchange 1 connects the adapter 12 to the adapter 13 through the base station connection terminal 9.
, The adapter 12 sends a number corresponding to the mobile terminal 4 to the adapter 13 by an in-band signal. The adapter 13 receiving the in-band signal converts this number into a signal system suitable for the base station 3 and transfers it, and the base station 3 calls the mobile terminal 4 through a wireless line. On the contrary, the outgoing call from the mobile terminal 4 is exchanged and connected by the private branch exchange 1 by a normal method without receiving a special operation by each adapter.
