This invention relates to an extension telephone calling method in which the extension telephone of that department is searched for and called.

[Technical background of the invention]

When calling someone at a company or government agency, first dial the main phone number of the company or government agency, call the agent or operator at the other end, and tell them the extension number or department name and the name of the person you are calling. A widely used method is to have a switchboard operator connect the corresponding extension telephone.

[Problem that the invention seeks to solve]

As mentioned above, even if a switchboard operator calls the other party's department or a telephone with a nearby extension number, the other party may be in another department, and if the destination is known in advance, the operator, etc. All you have to do is find out the department where the person is going and forward the phone call to that department, but if you don't know where the person is, there is no way to contact them. Also, if you are visiting multiple departments, you will have to call each department one by one to confirm that the person is there, so in such cases it will take a lot of time to call the person. It often happens that we are unable to contact each other even after a long period of contact.

Therefore, an object of the present invention is to provide a new extension telephone calling system that can improve the above-mentioned drawbacks with a simple configuration, instantly search for the location of the called party, and call the called party to an extension telephone near that location. The goal is to provide the following.

[Means for solving problems]

The extension telephone calling system of the present invention includes a plurality of portable radios each transmitting a signal containing a different code number for identification, and a plurality of portable radios located near the extension telephone receiving a signal containing the code number from a transmitter. In addition, a plurality of terminals transmitting the signals, each terminal transmitting a signal including a code number to be called in a preset order to these terminals, and a base unit connected by wire are provided, By matching the signal containing the code number from the base unit with the signal containing the code number received from each terminal, the position of the corresponding radio is determined, and the nearby extension telephone is called. It is something.

[For production]

Nowadays, when a person from one department goes to another department, the code number of the radio device to be brought to the operator is notified in advance, or a radio is adjusted to transmit a recognition signal representing the person's code number. put. When a person from outside or inside makes a telephone call to this person, the operator receives the call and inputs the code number using the main unit. The base phone polls each fractional phone in a predetermined order, finds the terminal that is receiving that code number, and finds the current location of the person to call.The switchboard then calls the extension closest to the current location. Ring the telephone and let the person know that you are on the phone.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.The radio device 1 has an identification code number of the person carrying the item, and when it receives a signal including the code number, it transmits a reception confirmation signal using weak radio waves. Although not shown, the code number is set by providing a numeric keypad or the like on the radio 1.

Each extension telephone 2 is provided with a terminal 5.5' which receives, through its antenna 4, a reception confirmation signal transmitted from the antenna 3 of the radio 1. These terminals 5, 5' are connected by wire to a base unit 7 in a telephone exchange room via a telephone line 6. These terminals 5 and 5' are.

One unit may be placed in each department, or each extension telephone may be provided with one unit. Telephone line 6 is also connected to a telephone exchange, not shown. A parent telephone 8 and a computer 9 are connected to the parent TA7. this computer 9
is the code number, the name of the person corresponding to it, and each terminal 5.
The computer 9 also stores information such as the department where
The code number signal from radio 1 is sent to which terminal 5'.
Information such as the code number, the name of the person corresponding to the code number, and the department where the person is sent is displayed on the display device IO. The computer 9 is equipped with an automatic dialing function that dials the extension telephone 2 of the terminal 5' that receives the corresponding code number by operating a keyboard (not shown) by the operator, and also allows the operator to change or correct the code number. Make sure you can do it.

Suppose that a person goes out to another department and sets his own code number by operating the numeric keypad of radio device 1, and then takes this radio device 1 with him. On the other hand, the computer 9 connected to the base unit 7 polls the set code number via each of the terminals 5, 5' and controls the polling to output a signal containing the code number. That is, the computer 9 first instructs the terminal 5 to output a signal containing the code number. The terminal 5 outputs a signal including the code number in response to this command. However, in the area of terminal 5, radio device 1 with the corresponding code number is
Since there is no confirmation signal, no acknowledgment signal can be obtained. Next, the computer 9 issues the same command as the previous one to the next terminal 5'.

A signal containing the code number from the terminal 5' is received by the radio 1, and a reception confirmation signal is transmitted via the antenna 3 using weak radio waves. The transmitted reception confirmation signal is received by the terminal 5', and this received signal is transmitted to the computer 9. Based on the received signal from the terminal 5', the computer 9 detects that the wireless device 1 with the code number is in the area of the terminal 5', that is, the person with the code number is near the terminal 5'. The person's department is recorded and displayed on the display device 10 of the computer 9. If this person receives a call from outside, the computer 9 inputs the person's code number and calling signal. When the radio device 1 receives this calling signal, it transmits a confirmation signal, and the base unit 7 receives the confirmation signal from the terminal device 5.
The corresponding location is determined from , the extension telephone of the determined location is automatically dialed, and the extension telephone 2 is called. Since the position of each radio is also displayed on the display device 10,
Based on the display, the switchboard operator or the like may manually call the extension telephone at that location.

In the above-mentioned embodiment, the display device 10 is provided in the base device 7, but each terminal device 5 may be provided with a display device.
By transmitting the information to the terminal 5' and recording the data at each terminal 5', any number of people can determine the location of the person they are looking for at each terminal. In this case, if there is multiple data, should it be displayed on a large screen?

Alternatively, the information may be displayed in one line and sequentially displayed in a scroll-up manner.

Note that when transmitting signals containing code numbers continuously, the code numbers may be prioritized in advance and searched according to the priority order. Also,
If sending intermittently, change the interval for each code number.

If signals containing two or more code numbers are received at the same time, they can be separated and received by receiving the next signal.

〔Effect of the invention〕

As described above, in the extension telephone calling system of the present invention, each department or each extension telephone is equipped with a terminal that receives an identification signal such as a code number, and a mobile phone is used to identify the person using a radio carried by the person. By transmitting a signal and constantly monitoring it on a lift, it is possible to confirm the location of the person. This allows the switchboard operator to immediately know the location of a caller even if the person receives a call from outside, and the caller can route the call via an extension telephone close to that location, allowing the call to be transferred quickly and accurately. . Furthermore, since the radio waves from the wireless device are used for communication in a relatively narrow space within a room, only weak radio waves are required and no application procedures are required, so the device itself can be made smaller and provided at a lower cost.
