Abstract

PURPOSE:To improve the convenience for users not only by displaying the telephone number of a calling subscriber on a pager, but also by connecting a called subscriber automatically to a calling subscriber being held only by inputting the telephone number of the called subscriber and a called display signal to an exchange in a system which calls the page automatically in telephone absence. CONSTITUTION:When there is incoming call to a telephone set 1 whose absence is registered in the exchange 3, an audio response guiding device 7 informs the caller that the telephone set is in an absent state and also calls the pager 2 by radio. The person who carries the called pager 2 dials the telephone number of the absence-registered telephone set 1 from a proper terminal 9 and then the exchange 3 connects the terminal 9 to the originating telephone set 4 automatically. Therefore, the caller is connected to the absent called subscriber while the telephone circuit is held. Consequently, troublesome operation is not necessary.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention automatically calls a pager, which is a mobile device, using a wireless call in response to a telephone call when the user is absent, and The present invention relates to a wireless call connection system in which a call path is set up and a conversation can be made with a caller by the caller responding via a telephone network.

(Prior art) In the wireless calling method currently in widespread use, the called pager either calls a predetermined contact number or, in the case of a pager with a display function, follows the displayed telephone number. It was used to make telephone outgoing connections.

This method has the following drawbacks.

(1) The called party is required to read the displayed number without error and dial the number without error.

(2) Furthermore, since the caller must disconnect the call and wait for the incoming call to be connected, there is a risk of being interrupted by other calls, such as when the caller wants to make an emergency contact, resulting in instability.

(Problems to be Solved by the Invention) The purpose of the present invention is to eliminate the problems of the prior art, and, ■The caller can be connected to the called party by placing the call on hold, and ■The called party can be connected to the called party by using a pager. To provide a wireless call connection system that automatically connects to a caller by transmitting one's own number and a signal indicating that a wireless call has been received to a telephone network when a call signal is received. It is in.

(Means for Solving the Problems) A feature of the present invention is that when an incoming call connection request is generated from a calling telephone to a telephone registered as absent in an exchange, the exchange automatically switches to a wireless call. A call signal is transmitted wirelessly, and the called party who receives the call signal,
The calling number of the called pager is sent from a terminal connected to a switching network, and the switching network uses a wireless calling connection system that automatically switches and connects the calling telephone and the terminal.

(effect) According to the invention, the switching network has the following additional functions:

■The exchange (3) that requested the wireless call receives the dial from the non-wireless caller and the called display signal, identifies the trunk on hold based on that information, and interconnects both lines with the trunk. Ability to connect to.

■In addition to the dial reception function, the subscriber line exchange (5) has a function of receiving and analyzing a called display signal, and a function of transferring the signal.

When a call is received on a telephone registered as absent in the exchange (3), the voice response device notifies the caller that the caller is absent, and also calls the pager by radio. When the person carrying the called pager dials the telephone registered as absent from an appropriate terminal, the telephone exchange automatically connects the terminal and the caller. Thus, the caller remains on hold and is connected to the absent called party.

(Example) FIG. 1 is a system configuration diagram showing an embodiment of the present invention.

1 is the incoming telephone, and when the owner of the telephone is absent,
He registers his absence on exchange 3 and takes pager 2 with him when he goes out. The originating telephone 4 desiring an incoming call connection while the terminating telephone 1 is absent makes a call and dials the telephone number of the terminating telephone 1. It enters from the originating exchange 5 and enters the exchange 3 via the trunk 6. The exchange 3 activates the voice response guide device 7 to inform the calling telephone 4 that the telephone is absent, and activates the wireless call transmitter 3 8 to make a wireless call. Pager 2
The carrying person uses a terminal 9 such as an appropriate telephone to make an outgoing connection to the telephone 1 registered as absent. From the exchange IO, the communication is relayed to the exchange 3 by the incoming trunk 11, and in the exchange 3, the trunk 6 and trunk 11 are interconnected by the combined trunk 12, thereby establishing a communication path between the originating telephone 4 and the terminal 9. Ru.

FIG. 2 shows an example of an operation sequence.

When the receiving telephone 1 becomes absent, it first registers its absence with the exchange 3.

When the exchange 3 receives the above-mentioned absence registration signal, it records the absence registration and returns confirmation of acceptance completion to the requester.

The originating telephone 4 makes an outgoing connection to the terminating telephone 1 . The originating exchange 5 sends the terminating telephone number IDI and the originating telephone number ID2 to the terminating exchange 3.

When the incoming exchange 3 determines that the subscriber is within its own station based on the received ID2, it checks whether the subscriber is absent and sends the ID2.
Since the subscriber is registered as absent, the normal incoming call connection is not made and the radio calling operation is started. First, the voice response device 7 connected to the exchange 3 is activated, informs the caller 4 that the receiving telephone 1 is not available, and asks whether or not he wishes to make a wireless call. When the caller desires a radio call, the exchange 3 sends the calling telephone number ID2 to the radio call transmitter 8 along with the call signal IDI. The transmitter 8 analyzes the received ID1 and calls the pager 2 using a predetermined radio frequency.

The transmitter 8, which sent out the radio wave for the radio call, reports to the calling telephone 4 via the exchange 3 that it has sent a calling signal, and guides the caller to wait with the call on hold.

The called party who receives the wireless call responds using a nearby terminal 9 such as a telephone. In the case of a telephone, the user dials his or her own telephone registered as absent using a normal outgoing connection. At this time, a signal indicating that it is a response to a wireless call,
For example, by inputting a predetermined signal such as ##*, the call can be distinguished from a normal incoming call.

In addition to telephones, dedicated terminals may also be considered. For example, a telephone terminal with a function that automatically sends a call display signal indicating that a call is being received and one's own telephone number to the telephone network by inserting a pager that stores one's own telephone number. If developed, it will greatly contribute to improving user convenience.

The exchange that has received this signal uses its normal telephone exchange function to extend a train for the call to the terminating exchange 3 and enters the terminating exchange 3 via the incoming trunk 11. At this time,
Naturally, it is necessary to add a called indicating signal along with the telephone number to distinguish it from a normal incoming call. The terminating exchange 3 uses the called display signal and the terminating telephone number to refer to the storage device that stores the record of absences, finds the trunk number of the incoming trunk 6 of the on-hold terminating line, and connects the trunk 11 and the interconnecting trunk 12. By connecting via the telephone 9, the telephone 9 and the caller telephone 4 can communicate with each other.

Because it works in this way, a telephone subscriber who has registered as an absentee will be able to see the incoming call on his or her pager every time a call is received on his or her phone, and even if the caller's phone number is not displayed, By simply dialing a phone number, a communication line can be automatically established with the caller.

(Effects of the Invention) As described above, the present invention uses a system that automatically calls a pager when the telephone is not available, without informing the called party of the caller's telephone number (without displaying it on the pager).
The called party simply inputs his or her telephone number and called signal into the exchange network, and the caller is automatically connected to the caller on hold; the called party does not need to perform any special operations. This has the effect of allowing you to make calls without any problems.

Also, for the caller, there is a great advantage in that if he or she really wants to make an emergency call, he or she can connect to the line while remaining on hold. That is, in the method of hanging up the phone and waiting, there is a risk that an incoming call from a third party will be connected while waiting. From this point of view, there is no need to worry about waiting on hold, especially in communication ranges where there is a high probability that the other party will respond, such as a local communication system. It can be said that this is something that can be demonstrated.
