Abstract

PURPOSE:To make a smooth communication by using a pocket bell even when a called subscriber is absent by providing a pocket-bell calling setting means, a means for sending a message to a calling subscriber, and a means for allowing a service state. CONSTITUTION:Subscriber circuits 2A-2N detect on-off states of handsets corresponding to telephone sets 1A-1N and detect the supply of currents, transmission of various signal tones, or dial signals of the telephone sets. A control part 4 performs entire control over this system such as a check on the states of the subscriber circuits 2A-2N, indication of the transmission of various signals, a decision on a dial signal, etc. A channel 5 makes a necessary connection by an indication from the control part 4. An announcement trunk 6 sends out messages to the telephone sets 1A-1N through the channel 5 on the basis of the indication of the control part 4. A radio paging trunk 7 calls a corresponding pocket bell 8 on the basis of the indication of the control part 4. Consequently, even if the called subscriber is absent, a communication is made smoothly by using the pocket bell 8.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF THE INVENTION The present invention relates to an automatic switching system that allows telephone calls to be made in response to incoming calls when the user is away from his or her own telephone.

Conventional configurations and their problems Traditionally, incoming calls that are dropped when you are away from the telephone installation location are either not picked up at all or are picked up by someone else. However, as telephones have become more widespread in recent years, people have shifted from having them for shared use to having them for personal use.
Since I take fewer calls from other people, I end up losing contact with them when I leave my seat.

As a countermeasure to this problem, a function has recently come into use that allows users to set their phone to automatically forward incoming calls to a phone installed at their destination before leaving their desk.

This function is extremely effective when the destination is fixed at one location, but is not effective when the destination is multiple.

Another method is to use a public address system from the telephone to call out all at once when the person you are calling is not home, and the called party who hears the call when he or she is away answers using the nearest telephone. However, if the range where the amplification can be received is limited, or there is a high possibility that the call will be overheard, or if all missed calls use this method, the amplification will be carried out frequently, and even unrelated people will be able to hear it. There are drawbacks such as:

OBJECTS OF THE INVENTION It is an object of the present invention to provide an automatic switching system that eliminates the above-mentioned conventional drawbacks and allows smooth communication using a pager even when the called party is away from the callee's seat.

Structure of the Invention The present invention allows an incoming call to the telephone to be set to a pager ringing mode by dialing the telephone, and when the holder (user) of the telephone leaves his or her desk, he or she takes the pager with him and during this time When a call is received on the telephone, the caller is first informed as a message that the caller is away from his/her seat and instructions on how to operate the call.

Thereafter, when the calling party performs a calling operation according to the message, the called party waits for a response.

In this case, the waiting state can be either on-hook or off-hook.

The caller's operation calls a pager belonging to the person who owns the telephone, and the person who owns the telephone uses the nearest telephone to dial a response.

If the caller is off-hook and waiting for an answer,
The caller and the owner of the telephone set are connected to each other with a signal sound indicating the answer.

When the caller is on-hook and waiting for a response, a special ringtone is sent to the caller, and when the caller responds, the caller enters the talking state.

Note that if the calling party is busy with another call at this time, the call will be in a standby state and this will be notified by a signal tone. Then, if the phone holder waits in the same state and the caller's phone goes on-line, a special ringtone will be sent to the caller in the same way as above, and the caller will be put into a talking state when the caller answers. becomes.

If the caller does not perform a pager ringing operation, the silent bell will not ring and the call operation will end when the caller goes on-hook.

Meanwhile, the telephone owner returns home and cancels the pager setting by dialing, thereby returning the telephone to a normal telephone.

As mentioned above, as a notification when leaving the desk, a pager call registration 5 is sent from the telephone, a notification to the caller that the caller is away from the seat, and a notification of the caller operation.

This provides an excellent means of communication by using the nearest telephone to answer the call.

Description of examples An embodiment of the present invention will be described below with reference to the drawings.

In Figure 1, 1A to 1N correspond to telephones, and 2A to 2N correspond to each telephone 18 to 1N, and detect the on/off state of the handset, supply current, send out various signal sounds, or use this telephone. 3 indicates the status of each telephone set 1A to 1N.

a memory section that stores the configuration state or the take being processed;
4 checks the status of subscriber circuits 2A to 2N, instructs to send out various signals, and determines dial signals.

A control unit is in charge of all controls of the own system such as writing and reading data to and from the memory unit 3; 5 is a communication path for making necessary connections according to instructions from the control unit 4; and 6 is a communication path for making necessary connections based on instructions from the control unit 4. An announcement drunk that sends a message to the telephones 1A to 1N etc. via a route 5, a radio station L trunk 7 that calls a corresponding pager based on instructions from the control unit 4, a pager 8, and a pager 9. It's an antenna.

FIGS. 2 to 4 show information directly related to the present invention, such as pager settings for each telephone set in the memory section 3.

Next, the operation will be explained with reference to FIG.

A case will be explained in which the holder of one telephone (hereinafter referred to as a person) leaves his/her seat. When a person first picks up a telephone, the off-hook status is communicated to the controller 4 via the two subscriber circuits. The control unit 4 gives a dial tone sending instruction to two subscriber circuits, and a dial tone is sent to one telephone. The person then registers with the pager, for example by dialing '1001' (a). This setting dial data is transmitted to the control unit 4 via the two subscriber circuits, where the dial data is analyzed. The pager is registered and the pager number is
001'' and the image information is stored as shown in FIG.

A is away from his desk with the pager number ``001'', but if caller B uses telephone 1B to call someone during this time, the on-hook state of telephone 1B is transmitted via subscriber circuit 2B. The dial tone is transmitted to the control unit 4, and the dial tone is transmitted from the control unit 4 to the subscriber circuit 2B to the telephone 1B (mouth).When B dials the number of one telephone,
This dial information is transmitted to the control section 4, but the control section 4
First, the contents of the memory section 3 shown in FIG. 2 are checked. Since the previously registered take is stored there, the control unit 4 determines that it has been registered, and sends the call path 5 to the telephone 1B.
and instructs the connection of the announcement drunk 6, and controls the transmission of the message.

This informs fiB that the person is away and how to use the pager to call (c). Here, if B performs a pager calling operation, the dial information is sent to the control unit 4 via the subscriber circuit 2B.
can be conveyed to. After decoding, the control unit 4 sets up an incoming call display in the memory unit 3 shown in FIG.
Suppose that B is on-hook with telephone 1B after calling the pager (E). The pager held by A rings. When the called person answers using the nearest telephone 1N and dials ``001'', this dial information is transmitted to the control unit 4 via the subscriber circuit 2N, and the dial information is transmitted to the control unit 4 via the subscriber circuit 2N, The memory contents of are checked. This memory content is pager number “○01”
There is an incoming call, and the control unit 4 writes that the calling telephone is 1B and its status is on-hook waiting, so the control unit 4 sends a special message to the telephone 1B indicating that it is a response to a pager call. Since the subscriber circuit 2B is instructed to send a ringing tone, a special ringing tone sounds on the telephone 1B (G). If B responds, (g) control unit 4
Instructs the connection of the telephones 1B and 1N to the communication path 5, and also controls the communication state of the subscriber circuits 2B and 2N, so that the telephones IB and 1N are in the communication state, and A and B are in the communication state (man). Also, at this time, the control section 4 rewrites the state of the memory 3, dials the caller's telephone shown in FIG. 2, and prepares for the next call (No).

Further, if B waits in the off-footer state after calling the pager, this state is written into the memory section 3 by the control section 4 as shown in FIG.

In this state, if the person called by the pager answers (), the memory contents shown in FIG. The circuit 2B is instructed to send out a response signal tone, and then the communication path 5 is instructed to connect the telephones 1B and 1N.
After that, control of telephone calls to subscriber circuits 2B and 2N is performed. As a result, telephone 1B receives an answer signal tone (6), and then telephone IB.

It will be a 1N call (wa). At this time, the calling party telephone shown in FIG. 3 is cleared and ready for the next call.

When B puts the telephone on-hook state after calling the pager and uses the telephone thereafter, the state of the telephone 1B is written into the memory section 3 by the control section 4 as shown in FIG. At this time, if the person called by the caller responds, the control unit 4 sends a signal tone to the subscriber circuit 2N indicating that the caller is busy, based on the memory contents shown in FIG. The signal tone can still be heard on the telephone 1N. B
When the caller in FIG. 4 finishes using the telephone, the control unit 4 changes the caller's usage state in FIG. The result is the same as that, and the call is between telephones 1N and 1B.

If B dials the number of one person on the telephone and does not perform the operation to call Boke or Nodobell after hearing Metsusafe, the calling party's telephone in FIG. 2 will not be registered in the memory unit 3 and Boke/ This is not a call operation of the nodebell.

If the person returns to their seat and the pager is no longer needed, one person can send a registration cancellation number to the phone, such as '
By dialing “○o o o”, the control unit 4
As a result, the PokenoDobell setting telephone and pager number shown in FIG. 2 in the memory section 3 are canceled, and the telephone can be used by one person as a normal telephone from now on (power).

Effects of the Invention As described above, according to the present invention, when you are at your seat, you can use it as a normal voice, and when you are away from your seat, you can register the use of the pager by dialing your own telephone, so that the pager does not ring. Telephone contact can be made from anywhere within possible range. In addition, if the caller is away from their desk when making a call, the caller can know from Mensage, and if the caller wishes to continue the call, the caller can be notified by Mensage and the caller can be called directly by pager. This provides a speedy and reliable means of communication for the called party.
