Description

Description: TECHNICAL FIELD The present invention relates to a radio paging system.

[Conventional technology]

Generally, there are pagers served by NTT (Nippon Telegraph and Telephone Corporation) and low-power private paging systems as wireless paging systems.

Conventionally, this type of wireless paging method is one-way communication. When a caller dials the telephone number of a pager (paging receiver), a transmitter connected to the telephone line wirelessly transmits a signal to the pager. , The pager sounds, or the phone number is displayed. The person holding the pager recognizes that a call has been made by the ringing or display, and informs him that he has confirmed the call by calling a predetermined place or a displayed telephone destination.

[Problems to be Solved by the Invention] In the above-mentioned conventional wireless paging method, when a person who has a pager receives a call, he or she calls a predetermined telephone number or a display telephone destination every time. Must be done and this has become a hassle.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a wireless paging system in which a pager holder can confirm a call without calling each time.

[Means for solving the problem]

A radio paging system according to the present invention includes a circuit connection device including a circuit switching unit, a radio paging detection unit, a radio paging control unit, a radio paging response call detection unit, and a radio paging / radio paging response call connection control unit. A radio paging transmitter connected to the line connection device for transmitting a paging signal under the control of the radio paging control unit, a signal from the radio paging transmitter being received, and a paging code ( ID number) is your own IC
A pager with a transmitter that sends out a signal containing its own ID number at a different frequency when the numbers match, a radio receiver that receives a signal from this pager, and a receiver connected to this receiver and the line connection device. A telephone for calling the line connection device when the radio receiver receives a signal from a pager.

[Action]

In the above-described method, when a pager receives a signal addressed to itself, the pager sends a signal including its own code by an attached transmission system, receives this signal by a radio receiver, and makes a call by a telephone, thereby making a line by a telephone. It is possible to answer and talk to the telephone that called the pager through the connection device.

〔Example〕

 Next, the present invention will be described with reference to the drawings.

FIG. 1 is a system configuration diagram of an embodiment of the present invention.
1 is a line connection device, 2 is a wireless telephone, and comprises a telephone 3 and a wireless receiver 4. 5 is a pager with a transmitter, which is a feature of the present invention, and 6 is a radio paging transmitter, that is, a paging transmitter. 2A is the wireless telephone 2
7,7A is a fixed telephone.

FIG. 2 is a block circuit diagram of the pager 5 with a transmitter shown in FIG. 11 is a transmission / reception antenna changeover switch, 12 is a reception high-frequency amplifier, 13 is a reception intermediate frequency amplifier, 14 is a demodulator, 15 is an ID number decoder, and 16 is an ID-ROM (read only) storing the pager ID number. Memory), 17 is an ID number encoder, 18 is a modulator, 19 is a transmission intermediate frequency amplifier, and 20 is a transmission high frequency amplifier.

FIG. 3 is a block diagram of the line connection device 1 shown in FIG. 21 is a circuit switching unit having the same function as an electronic exchange or a PBX, 22 is a radio call response call detection unit, 23 is a radio call detection unit, 24 is a call control unit, and 25 is a radio call / wireless call response call connection control. Department.

The operation of the present embodiment having the above system configuration will be described with reference to the flowchart of FIG. In FIG. 4, the line connection device 1, the wireless telephones 2, 2A, the pager 5,
The paging transmitter 6 and the fixed telephones 7 and 7A correspond to the reference numerals in FIG. 1, respectively.

When a call is made from the fixed telephones 7 and 7A to a certain pager, a radio call signal 101 is output to the line connection device 1 therefrom. The line connection device 1 makes a call in the same manner as in a pager or a private paging, and sends a call signal 102 to the paging transmitter 6. Then, the paging transmitter 6 makes a corresponding call and sends the corresponding ID to the pager 5.
A call signal 103 including the number is transmitted.

The pager 5 receives the calling signal 103 by the receiving system shown in FIG. 2, extracts the ID number from the signal, and compares the ID number in the ID number ROM 16. It responds only when it receives a signal containing the same ID number as its own ID number, and sends out a signal 104 containing its own ID number at another frequency through the transmission system.

The signal 104 is received by the wireless receiver 4 of the wireless telephone 2, and the telephone 3 sends a call signal to the line connection device 1.
Send 105.

The line connection device 1 detects the call signal 105, and internally connects a line corresponding to the signal 101 received first and a line corresponding to the call signal 105. Then, the line connection device 1 sends the ring back tone signal 10 to the fixed telephones 7 and 7A.
6 to the telephone 3 of the wireless telephone 2. The wireless telephone 2 rings the bell of the telephone 3 and picks up the handset, from which a desired call can be made.

〔The invention's effect〕

As described above, according to the present invention, when an ID number included in a signal matches its own ID number, its own ID
A pager is configured to be able to transmit a signal including a number, and a signal from this pager is received by a radio receiver, and the telephone sets a call to the line connection device when receiving the signal. With such a configuration, it is possible to automatically make a response call without having to call the pager holder again and receive a call with the wireless telephone.
