Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a telephone call control system, and more particularly to a call control system that can make communication by telephone more convenient through simple usage.

Electronic exchanges can offer many new services to subscribers.

That is, by controlling the storage program, for example, speed dialing, call waiting service, forwarding service, answering machine service, message board service, videophone, factor□
and other data communication services.

However, even with these services, once you are away from your phone, you cannot enjoy the convenience at all.

In other words, in the conventional system, as shown in FIG. connected to.

Further, an additional device 4 for special services is installed in the exchange 3 as necessary, and various services are provided.

In other words, in conventional telephones, the telephone number and telephone set are each fixed, and the exchange provides various services only to the telephone set corresponding to the accommodation location number (telephone number) of the subscriber line.

Thus, for example, in the case of a speed dial service,
If you conveniently use your registered abbreviated number from your own phone, when you go out and make a call from another phone, the non-abbreviated number (normal dialed number) becomes unknown.
It is often extremely inconvenient to be unable to call the other party.

In addition, in the case of forwarding services, it is necessary to register the forwarding destination phone number by dialing when you leave your seat, but if you leave your seat in a hurry or are called, dialing is cumbersome and you may forget to register. There are many cases where this happens.

Even if the call is forwarded by registration, the user must cancel the registration by operating a dial when returning home, but if the user is busy, the user often forgets to cancel the registration, and the disadvantage is that the incoming call cannot be received.

You can also change the forwarding destination of the forwarding service from a remote location,
When listening to the contents of an answering machine, it is necessary to send the key number to prevent manipulation by mischief or malicious intent, which is not easy to operate.

In this way, conventionally, as long as you use your own phone, you can enjoy various services, but in order to receive these services, you have to press complicated buttons, so it is difficult to use the equipment. However, in many cases, it is not actually utilized.

By the way, subscribers are not always on standby at their homes or workplaces, but may travel or go to customer sites, government offices, other external buildings, or offices.

Furthermore, even within the same building, people often leave their seats due to meetings, communications, meetings, etc.

Therefore, mobile services such as car telephones, train telephones, and ship telephones have made it possible to communicate between mobile subscribers and regular subscribers, or between mobile bodies, but it has become possible to communicate between mobile subscribers and general subscribers, or between mobile bodies. In addition, you cannot receive various services like you would with your own phone.

Furthermore, mobile phones are used to alleviate the inconvenience of going out, but they are very expensive, so not everyone can afford to have one.

Pagers are also commonly used, but they only notify users of incoming calls; they cannot directly communicate with the other party or provide various services through exchanges.

The purpose of the present invention, in order to eliminate these drawbacks, is to provide a system that allows you to make and receive calls using a telephone other than your own, without having to perform complicated operations each time you use a variety of complex telephone services. The objective is to provide a control method.

In the present invention, each person carries a transmitter that transmits radio waves or ultrasonic waves modulated with a code or frequency specific to the individual, and each telephone is equipped with a receiver that receives and demodulates the radio waves or ultrasonic waves. , notifies the exchange via a controller in the telephone or the subscriber line of the telephone that the person carrying the transmitter is located in the vicinity of a telephone, and causes the controller or exchange to carry the transmitter. The foregoing objectives are achieved by controlling incoming and outgoing calls for individuals who do so.

Hereinafter, the present invention will be explained in detail with reference to the drawings.

FIG. 2 is a diagram showing the basic structure of a telephone according to an embodiment of the present invention.

In the present invention, each person carries a transmitter 9, and a telephone 13 includes a receiver 1 and a controller 8 in addition to a handset 1 and a telephone circuit 2.

The transmitter 9 emits radio waves or ultrasonic waves modulated with codes or frequencies that differ from person to person, and has a built-in carrier radio wave or ultrasonic oscillator.

Additionally, in order to notify the location of the transmitter 9, there is a built-in antenna that transmits radio waves or ultrasonic waves. There is no need for a large antenna such as a telephone antenna.

When each person places the transmitter 9 in their pocket or attaches it to their clothes and it reaches the vicinity of their own telephone 13, the constantly transmitted radio waves or ultrasonic waves are received and demodulated by the receiver 1 of the telephone 13. By being notified to the controller 8 and the exchange 3, the controller 8 and the exchange 3 identify the transmitter 9 of the owner of the telephone 13.

Therefore, in this case, it operates in the same way as a conventional telephone.

As the controller 8, a microcomputer is used.

When the transmitter 9 moves away due to the owner of the telephone 13 being away from the seat, etc., the controller 8 and the exchange 3 will no longer receive the signals that they had been receiving. Incoming calls can be forwarded without any operation on the telephone 13.

Of course, by specifying the message in advance, the message transmitting/receiving device can be operated during an absence instead of forwarding.

If the nearby transmitter 9 is connected to someone other than the owner of the telephone 13, it sends the signal received and demodulated by the receiver 1 to the controller 8 and sends it via the subscriber line 5. By sending the call to the exchange 3, the telephone 13 can receive an incoming call from someone other than the owner.

In this case, it is necessary for the owner of the telephone 13 to take measures in advance to allow other people to receive calls.

The exchange 3 identifies the signal sent from the telephone 13 and its accommodation location number, and rewrites the memory of the special service additional device 4, so that calls made and received by the individual who owns the transmitter 9 are transferred to the telephone 13. to do so through.

Since the signal from the transmitter 9 can also be used as a personal reference signal, it can be used as a key number for operating one's own telephone 13 in a remote location.

That is, only an individual carrying a personal transmitter 9 can call the exchange 3 via a telephone 13 other than the telephone dedicated to that individual.
It is possible to change the forwarding destination set in advance and read messages when the user is absent.

In addition, by sending the key number through a telephone 13 other than the personal telephone, the individual can also make a call using a pre-registered speed dial.

In this way, the location of each individual carrying the transmitter 9 is
The signal received and demodulated by the receiver 7 in the telephone 13 is
By sending it to the exchange 3 via the subscriber line 5, it can be determined from the accommodation position of the exchange 3.

If a plurality of telephones 13 exist in the vicinity of the transmitter 9, the plurality of telephones 13 each send a signal indicating their location and information on the received field strength at each receiver I to the exchange 3. As a result, the exchange 3 selects the subscriber line 5 with the highest electric field strength and connects the incoming call to the individual carrying the transmitter 9 to that subscriber line 5.

Further, when the telephone 13 is busy, it is possible to connect to the telephone 13 having the next highest electric field strength.

Therefore, the transmitter 9 and the receiver 7 can be implemented even if they have relatively low precision.

If complementary transmitters 9 exist in the vicinity of a telephone 13, the conditions for making and receiving calls can be changed by combining these transmitters 9.

For example, by instructing the controller 8, when someone else is near the telephone 13Q, the incoming bell will not ring and the call will be connected to the answering machine, or the caller's telephone number, etc. will be controlled. It is also possible for the owner of the telephone 13 to read the contents after the overload has left the vicinity of the telephone 13.

In this case, it is necessary to adopt an exchange system in which the calling subscriber's telephone number is also notified to the called subscriber.

FIG. 3 is a configuration diagram of a telephone set showing an application example of the present invention.

As shown in FIG. 3, in one building, a telephone 13 according to the present invention is installed in an office 11, a receiver I is also extended to a bedroom 10 and other rooms 12, and a transmitter 9 is installed. When the carrier is in the office 11 and other rooms 12, all incoming calls are transferred to the carrier, and when the carrier is in the bedroom 10 at night, only incoming calls from predetermined important parties are transferred, and other incoming calls are recorded. It is also possible to leave it there.

As described above, according to the present invention, the functions of the telephone or exchange can be changed by notifying the controller or exchange within the telephone of the combination of a transmitter and telephone located near the telephone. It has the advantage that various services can be automatically received according to the subscriber's wishes without requiring any operation.
