CONSTITUTION:A line switching equipment connected to a PSTN and a PBX is constituted of a ratio circuit controller 3, and plural base station radio equipments 5 and a moving machine 11. When the line switching equipment receives a dial number of the moving machine 11 from the PSTN and the PBX, the moving machine 11 is selected in accordance with a dial number. In such a case, when the apparatus is a deemed call apparatus 9 or the moving machine 11 to which plural telephone sets 8 are connected, an apparatus code and an ID number stored in advance in the controller 3 are added to an incoming signal, and the incoming signal is outputted to the controller 3. The controller 3 transmits the number obtained by adding the apparatus code and the ID number to the incoming signal from the base station radio equipment 5. The moving machine 11 confirms the apparatus code and the ID number stored in the moving machine 11 by receiving the incoming signal, and executes an incoming control to the telephone set 8 and the apparatus concerned in the deemed call apparatus 9.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a call termination method in a mobile communication system connected to a PSTN (general telephone network) or a PBX (private branch exchange facility).

(Prior Art) FIG. 2 shows a connection method and configuration of a conventional device for deemed telephone calls. In the figure, a radio section 21 receives an incoming signal transmitted from a base station radio, and a control section 22 confirms the incoming call to the mobile device. The telephone 23 and the device 24 for assumed calls are notified of the incoming call from the control unit 22 through the control line 25, but since the incoming signal does not specify or identify the incoming device, the call is recognized as an incoming call to the telephone 23 and the device 2 for assumed calls
Since it was not possible to distinguish between the incoming call and the incoming call to 4, one person intervened and made the call arrive. 26 is an audio line, and 27 is a control line.

(Problems to be Solved by the Invention) In the above-mentioned conventional call reception method, since there is no incoming call identification in the incoming signal, it is not possible to distinguish whether the call is received to a telephone or to a device for deemed call, and the mobile device receives the deemed call. There was a drawback that the language device could not automatically receive calls.

The object of the present invention is to overcome the drawbacks of the conventional technology and to be able to use devices for anonymous calls (facsimile machines, data modem devices, etc.) and mobile terminals to which multiple telephones are connected.

An object of the present invention is to provide an automatic call reception method that can distinguish between incoming devices and receive calls.

(Means for solving problems) The automatic call reception method for the deemed call device according to the present invention is as follows.

Deemed call equipment such as line switching equipment and radio line control equipment connected to PSTN and PBX, base station radio equipment, and mobile equipment side facsimile equipment and data modem equipment used in mobile communication systems equipped with mobile equipment are , by assigning device codes and ID numbers (incoming call identification),
When a call is received from a mobile device or a PBX to a device for a deemed call, the device code and ID number stored in advance in the circuit switching device are added to the incoming signal according to the dialed number, and the signal is sent to the mobile device through the base station radio. The mobile device compares the pre-stored device code and ID number with the incoming signal to confirm which of a plurality of deemed call devices connected to the mobile device or a plurality of telephones the call has been received.

(Function) According to the present invention, the line switching device stores the device code and ID number in the mobile device, so that if the call is made using the dial number that specifies the connected device from the PSTN, PBX, or mobile device, the call can be received. The mobile device can distinguish the incoming device and automatically receive the call.

(Example) An example of the present invention will be described based on FIGS. 1 and 3.

FIG. 1 is a block diagram showing the configuration of a mobile communication system according to the present invention. In the figure, 1 is a line switching device, 2 is a control line, 3 is a radio line controller, 4 is a control line, 5 is a base station radio, 6 is a central office line, a subscriber line, and 7 is a transmitting/receiving unit and a control unit. , 8 is a telephone, 9 is a deemed communication device, 10 is a connection line, and 11 is a mobile device. In this communication method, P
A line switching device connected to the STN or PBX is composed of a radio line control device 3, a plurality of base station radios 5, and a mobile device 11. When the line switching device receives the dial number of the mobile device 11 from the PSTN or PBX,
The mobile device 11 is selected according to the dialed number. At this time, in the case of the device 9 for deemed calls or the mobile device 11 to which a plurality of telephones 8 are connected, the device code and ID number stored in advance in the wireless line control bag @ 3 are added to the incoming signal, An incoming signal is output to the radio line control device 3. The radio line control device 3 transmits a signal obtained by adding a device code and an ID number to an incoming signal from the base station radio device 5. When the mobile device 11 receives the incoming call signal, it confirms the device code and ID number stored in the mobile device 11, and controls the incoming call to the device in the telephone 8 or the device 9 for deemed call.

FIG. 3 is a system flowchart showing the flow of connection when a call is received. In this system, the line switching equipment stores device codes and ID numbers, and according to the dial number from the PSTN (PBX), the device code and ID number are assigned, added to the incoming signal, and sent to the wireless line controller. Output. It is transmitted to the mobile device via the radio line controller or base station radio. The mobile device verifies the incoming call signal received by the transmitter/receiver with the device code and ID number stored in the controller.

The control section performs call reception control on the device (a device for a deemed call or a telephone), and the device outputs the completion of call reception preparation to the control section. The control section transmits a loop check signal from the transmitting/receiving section and waits for a loop check response.

The line switching device transmits a loop check response and a bell signal in response to the loop check signal. The control unit of the mobile device uses the bell signal to ring the bell of the device, such as the device for private calls. When the device confirms the bell signal, it outputs an 0FF-HOOK signal to the control unit and at the same time outputs a modem signal.

The line switching device switches to PSTN upon receiving the 0FF-H○OK signal.
(PBX).

(Effects of the Invention) According to the present invention, it is possible to automatically receive a call to a deemed call device of a mobile device in a mobile communication system. Even when several telephones are connected, by storing the device code and ID number in the circuit switching device and the mobile device, calls can be distinguished and automatically received, which has a great practical effect.
