Abstract

PURPOSE:To perform connection in real time and to save time by receiving a signal from a transmitter carried by a subject person, and performing incoming transfer to telephone set nearby at the moving destination of the subject person. CONSTITUTION:The signal from the transmitter 1 is inputted to a position recognition circuit 41 via a repeater 21. The circuit 41, when receiving the signal, delivers the position information of the transmitter 1 to a number retrieval circuit 42 based on the intermittent signal of the transmitter 1. The circuit 42 stores the position information in an extension position memory circuit 43. Next, when an incoming call from a transmission subscriber 5 arrives at an extension telephone set owned by the subject person originally, a transfer control circuit 44 receives a subject person retrieval request signal from a CPU, and reads out the information from the circuit 43 via the circuit 42. When read out information shows the telephone number of the telephone set 31 nearby at the present location of the subject person, the announcement of transfer is delivered via a delivery circuit 45, and also, a transfer connection request to the extension telephone set 31 is issued to the CPU. In such a way, the connection is performed in real time, and the time can be saved.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a private branch exchange, and more particularly to a private branch exchange that automatically searches for a contact party and transfers incoming calls.

[Conventional technology]

In conventional private branch exchanges with a call forwarding function, when a call is received from a contact party, the call is forwarded to a pre-registered extension telephone of the forwarding destination.

[Problem to be solved by the invention]

As mentioned above. With conventional private branch exchanges, if the other party is not available at the forwarding destination, the caller cannot contact the other party unless the next forwarding destination is registered, so the caller must either repeat the call or request a substitute answerer to leave a message. There is a drawback that it must be done.

[Means to solve the problem]

The private branch exchange of the present invention is a private branch exchange having an incoming call transfer function, and includes a plurality of repeaters that receive and relay signals from a transmitter carried by a target person, and which one of these repeaters receives signals. location recognition means for identifying the current location of the target person by identifying whether the target person is there; an extension location storage means for storing the search results of the search means, and when a call arrives at an extension telephone originally owned by the target person, the call is forwarded to the extension number of the nearest extension telephone of the target person read from the extension location means. It is characterized by

The apparatus further includes voice information transmitting means for transmitting information about the condition of the target person by voice to the originating subscriber when a call is received to the target person, and the position recognition means is configured to communicate with the one repeater. When the number of intermittent transmission signals received from the target person via the repeater exceeds a predetermined number of times, the current position of the target person is recognized as being fixed within the reception area of the repeater. Furthermore, the transmitter is characterized in that it is equipped with a current position notification means that starts sending out a transmission signal when operated when the current position of the subject who owns the transmitter is fixed.

〔Example〕

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

FIG. 1 is a block diagram showing an embodiment of a private branch exchange according to the present invention.

In FIG. 1, 1 is a transmitter carried by the subject; 21.

The private branch exchange 4 has an incoming call transfer function, and has an extension telephone 31.
.about.3n, a communication path switch 40 accommodating the calling subscriber 5, and a repeater 21. A location recognition circuit 41 receives a signal from ~2n and outputs location information for recognizing the current location of the person carrying the transmitter 1; a number search circuit 42 that searches for the extension number of an extension telephone; an extension location storage circuit 43 that stores the search results of the number search circuit 42; A transfer control circuit 44 that issues search control instructions and incoming call transfer control instructions; and based on the search data from the transfer control circuit 44, sends a transfer destination extension number and sends voice information indicating the status of the target person to the originating subscriber 5. A sending circuit 45 is provided.

Next, the operation of the present embodiment will be explained using an example of call transfer processing to a target person within reception area A.

The repeater 21 in the reception area A receives and relays the intermittent signal sent from the transmitter 1 at predetermined intervals. When this relay signal is first received by the position recognition circuit 41, it is sent to the transfer control circuit 44 as reception information. When the transfer control circuit 44 receives this received information, it transfers the communication path switch 4.
0 position recognition circuit 41 that sends a search request signal to 0
When the intermittent signal from the transmitter 1 is received a specific number of times (for example, 5 times) via one repeater 21, the number search circuit 42 assumes that the position of the transmitter 1 (the position of the subject) is fixed. 0 number search circuit 42 that sends location information to
stores this position information in the extension position storage circuit 43.

Next, when a call is received from the originating subscriber 5 to the extension telephone originally owned by the target person, the transfer control circuit 44 receives a target person search request signal from a central processing unit (not shown) as is generally known. Reads information regarding the condition of the subject from the extension location storage circuit 43 via the number search circuit 42;
Connection control processing is performed according to this status information.

That is, when the read information is the extension number of the telephone extension 31 closest to the target person's current location, the transmission circuit 45 is instructed to inform the calling subscriber 5 that the communication is being transferred via the call path switch 40. voice information (for example, an announcement such as "The other party is calling, please wait")
At the same time, it causes the central processing unit to issue a transfer connection control request to the extension telephone 31. Therefore, the central processing unit performs a generally known transfer connection process (connection from calling subscriber 5 to extension telephone 31 via call path switch 40).

Further, when information regarding the state of the target person is not read out from the extension location storage circuit 43, the transfer control circuit 44 instructs the sending circuit 45 to send information indicating that the transfer is not possible (for example, "The other party is on the move or is in the search area. Announcements such as "I cannot forward your call because I am outside, so please try calling again")
send out.

In the above embodiment, the transmitter always sends a continuation signal at a predetermined interval, but when the subject finishes moving and fixes the position, by operating the send button on the transmitter, the transmitter can transmit a continuation signal at a predetermined interval. It may also be possible to start transmitting a continuation signal.

〔Effect of the invention〕

As explained above, according to the present invention, calls can be forwarded to the telephone closest to the destination no matter where the person moves within the premises, so real-time connection is possible and time is saved. In addition, there are many benefits such as eliminating the need for telephone intermediaries on the floor to which the target person belongs, and furthermore preventing the calling subscriber from making repeated calls, thereby reducing traffic.
