Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a private telephone exchange system, and more particularly to a call forwarding telephone number registration system.

[0002]

2. Description of the Related Art In a conventional private telephone exchange system,
When transferring a call, a person who has moved inserts an IC card that stores his / her identification number into a telephone at the destination, so that the telephone sends data to the private branch exchange and the telephone number is transferred to the telephone. be registered. Therefore,
Calls to you are automatically transferred to your registered phone.

[0003]

In this conventional call transfer telephone number registration system, a person who has moved performs a telephone number registration operation from a destination telephone, so that a call to that telephone number is received. Since it is transferred, it is necessary to consciously perform the registration operation at each destination.

Further, if the user forgets to perform the registration operation after moving, the call addressed to himself will be forever transferred to a place where he / she does not exist, and the exchange side cannot detect that the registration operation has been forgotten. was there.

An object of the present invention is to provide an automatic call transfer telephone number registration system for a private telephone exchange system in which an individual telephone number is registered in the nearest telephone.

[0006]

In order to achieve the above object, the call transfer telephone number automatic registration system of the private branch telephone exchange system according to the present invention is a call transfer telephone number automatic registration system having an IC card and a telephone. Therefore, the IC card stores the individually assigned telephone numbers and has a transceiver, and the transceiver is integrated with the IC card, and the personal telephone number stored in the IC card. The telephone has a function of transmitting a signal including a signal with a weak electric wave and a function of receiving a response signal, and the telephone has a receiver for receiving a signal from the IC card and a response signal to the IC card with a weak electric wave. It has a transmitter for transmission and has a function of transmitting / receiving telephone number registration data to / from a private branch exchange.

[0007]

A receiver provided in each telephone receives a signal including an individual telephone number transmitted by a weak electric wave from an IC card with a transceiver carried by each person, and the telephone is called between the telephone and the private branch exchange. By transmitting and receiving the registration data of the number, the telephone automatically registers the personal telephone number in the nearest telephone by transmitting a response signal with a weak electric wave. As a result, it is not necessary to intentionally perform a telephone number registration operation at each destination.

[0008]

The present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a private telephone exchange system according to an embodiment of the present invention.

In the figure, a plurality of extension telephones 10 to 31 are connected to a private branch exchange 1, and a plurality of extension telephones are arranged in respective areas A to C.

Each of the extension telephones 10 to 31 has a transmission / reception function for transmitting / receiving a weak radio wave to / from an IC card 2 which can be carried by each person and has a transceiver 2a. Is sent to the private branch exchange 1 via a control line other than the communication line, and a signal is sent in accordance with an instruction from the private branch exchange 1.

Next, the operation of the present invention will be described with reference to the drawings. First, each extension telephone 10 to 31 transmits a signal including each identification code in a burst mode with weak radio waves of the same frequency at regular intervals, and in order to prevent radio wave interference with extension telephones in the vicinity as much as possible, a transmission cycle Is random within a certain range.

On the other hand, the IC card 2 with transmitter / receiver carried by each person also transmits weak radio waves in the burst mode and once in order to suppress radio wave interference with the IC card with transmitter / receiver carried by people nearby. After receiving the registration response signal from any extension telephone, the identification signal transmitted from that extension telephone cannot be received, or the radio wave including the identification signal of another extension telephone receives with a stronger electric field strength. Until it is done, I am trying not to send a signal for the next registration.

However, in order to prevent frequent registration in the vicinity in a short time and to prevent unnecessary transmission of radio waves when a signal from any extension telephone cannot be received for a certain time or longer, a transceiver is provided. The IC card has a function of determining whether to register with a timer.

Based on the above conditions, a specific operation example will be described below. If the person's telephone number assigned to a person is not registered on any extension phone, that is, if the person is absent or there is no extension phone nearby, When it comes near the extension telephone 10 of A, the IC card 2 with a transceiver carried by the person receives the identification signal transmitted from the extension telephone 10 and receives a registration request signal including a personal telephone number. Is transmitted by a weak radio wave.

When the extension telephone 10 receives the registration request signal a certain number of times without error, it sends a registration request signal to the private branch exchange 1, the private branch exchange 1 registers the telephone number with the extension telephone 10, and a registration response signal. To the extension telephone set 10. At this time, the private branch exchange 1 deletes the requested telephone number, if it has already been registered in another extension telephone, and registers it only in the extension telephone 10 in order to prevent it from being registered twice.

The extension telephone set 10 transmits a registration response signal in response to a response from the private branch exchange 1. When the transceiver IC card 2 receives the response signal from the extension telephone set 10, the transmission is terminated as registration is completed, and the extension telephone set is terminated. It enters the monitoring state of receiving the identification signal from.

When a call is made to the telephone number registered here, the private branch exchange 1 makes the extension telephone 10 receive the call.
In addition, the extension telephone 10 transmits a confirmation request signal at regular time intervals to check whether a person carrying the registered transceiver IC card 2 is nearby, and the confirmation from the transceiver IC card 2 is performed. If the response does not continue for a certain period of time, the private branch exchange 1 is requested to delete the registration of the telephone number.

Next, an example in which a person carrying the IC card with transceiver 1 moves from the extension telephone 10 in the area A to the extension telephone 21 in the area B will be described.
When the IC card 2 with a transceiver is separated from the extension telephone 10, it cannot receive the identification signal transmitted from the extension telephone 10, and enters the registration request signal transmission state. When the transceiver IC card 2 approaches the extension telephone 21 of area B, the transceiver 3 of the extension telephone 21 receives the registration request signal transmitted from the transceiver IC card a certain number of times, and the private branch exchange. The private branch exchange 1 registers the telephone number included in the registration request signal with the extension telephone 21 and deletes the registration of the same telephone number of the extension telephone 10 that has been registered so far. Then, the registration response signal is returned to the extension telephone 21.

The extension telephone 21 transmits a registration response signal in response to a response from the private branch exchange 1, and the IC card with a transmitter / receiver stops transmission upon completion of registration upon receipt of this registration response signal, and the identification transmitted from the extension telephone. Enter the signal reception monitoring state.

Further, when the person carrying the IC card with transmitter / receiver 2 moves near the extension telephone 22, the IC card with transmitter / receiver 2 receives the radio wave transmitted from the extension telephone 22 and receives the identification signal. It recognizes that it has moved again due to the change in the contents of, and executes the registration procedure for the extension telephone 22. After that, when moving to another area, registration is performed in the same procedure as above.

In practice, a plurality of extension telephones are installed in the same area, and the intervals are often within several meters. Repeating the registration processing between these extension telephones imposes a great load on the processing on the private branch exchange side. Therefore, it is considered that the extension telephone having the registration function is limitedly arranged, or the registration is performed only when moving between other areas.

[0022]

As described above, according to the present invention, a receiver provided in each telephone receives a signal including a personal telephone number transmitted by a weak radio wave from an IC card with a transceiver carried by each person. However, the telephone number registration data is sent and received between the telephone and the private branch exchange, and the telephone transmits the response signal by weak radio waves, so that the individual telephone number is automatically registered in the nearest telephone. Therefore, it is not necessary to consciously register the telephone number at each moving destination, the call is automatically transferred to the telephone near the place where it actually is, and the fact that the other party is absent is a private branch exchange. Can be recognized,
This has the effect that an appropriate message can be returned.
