Abstract

PROBLEM TO BE SOLVED: To permit incoming call which is a case of emergency, even when refusing incoming calls. SOLUTION: This incoming call connecting method is a method for connecting an incoming call, when originating a call from a terminal A on the side of call origination through an electronic exchange 1 to a terminal B on the side of call termination. When originating the call from the terminal A on the side of call origination through the electronic exchange 1 to the terminal B on the side of call termination, at the electronic exchange 1, the incoming of the call to the terminal B on the side of call termination is refused for a fixed time and after the lapse of the fixed time from that refusal of incoming call, the incoming of the call is permitted. Thus, even when the refusal of call incoming has been registered, all of the incoming calls is not refused, when calling the terminal on the side of call termination from the terminal on the side of call origination but the permission for incoming call can be provided as needed by waiting for the fixed time and contacting can for high-emergency can be taken.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming connection method for making a call from a calling terminal to a called terminal via an electronic exchange.

[0002]

2. Description of the Related Art Conventionally, in a private branch exchange, when a call is made from a calling terminal to a called terminal, a temporary incoming call prohibiting service is performed as a method of rejecting the incoming call by the intention of the called side. This is done from the receiving terminal in advance.
By using the special number dial (dial of a specific number determined in advance) or key operation of the multi-function telephone, incoming call prohibition registration is performed in the private branch exchange, and thereafter incoming calls to the receiving terminal are rejected, and Is a method of giving a busy tone or predetermined guidance.

[0003] A caller who hears a busy tone or predetermined guidance in the temporary call blocking service temporarily hangs up and calls again after a while.

[0004]

However, in such an incoming connection method, since the incoming call from the calling terminal to the called terminal is uniformly rejected, for example, the calling terminal urgently contacts the called terminal. However, there is a problem that the incoming call is rejected even if it is desired to perform the call. In addition, there is a problem that even the receiving side terminal cannot receive such an emergency contact by uniformly rejecting the incoming call.

[0005]

SUMMARY OF THE INVENTION The present invention is an incoming call connection method made to solve such a problem. That is, the present invention relates to an incoming connection method when a call is made from an originating terminal to an incoming terminal via an electronic exchange,
When a call is made from a calling terminal to a called terminal via an electronic exchange, the electronic exchange rejects the incoming call to the called terminal for a certain period of time, and permits the incoming call after a certain period of time has passed since the rejection of the incoming call.

In such an incoming call connection method, when a call is made from a calling terminal to a called terminal, the incoming call is temporarily refused, and the incoming call is permitted after a certain time has elapsed. In other words, if a call is made from the calling terminal and the incoming call is rejected, if the call is stopped at that point, the incoming call to the called terminal will not be made. Further, even if the incoming call is rejected, the incoming call is permitted by waiting for a certain period of time, so that the calling terminal can select the incoming call permission according to the importance of the call.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the incoming call connection method of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram illustrating the configuration of an electronic exchange used in the incoming call connection method of the present embodiment. The incoming call connection method of the present embodiment is, for example, when a call is made from a terminal A to a terminal B, an incoming call from the terminal A on the calling side to the terminal B on the called side is rejected for a certain period of time, and the incoming call is During the refusal, it is characterized in that a guidance or an audible sound is heard to notify that the callee does not want to make a call other than in an emergency, and the terminal B is called after a predetermined time has elapsed.

The electronic exchange 1 has a subscriber circuit 21 for accommodating a terminal A and a subscriber circuit 2 for accommodating a terminal B.
2, a guidance device 3 for flowing guidance during call rejection, a switch 4 for connecting an extension to a trunk, a connection between extensions, and a connection to the guidance device 3, and a central processing unit 5 for controlling each unit. , A main storage device 6, a terminal memory 61 provided in the main storage device 6 for storing information of each terminal, and a timer 7 for counting the time until the incoming call is permitted. In the electronic exchange 1 shown in FIG. 1, two terminals A and B are connected, but the same applies to a case where more terminals are connected.

FIG. 2 is a schematic diagram illustrating a terminal memory. The terminal memory 61 is provided with a storage area for each terminal, and is stored in a storage area designated by a unique address ad corresponding to the telephone numbers of the terminals A and B in the main storage device 6 shown in FIG. Is stored. In the present embodiment, a part of this storage area can be used to store a waiting call registration in progress flag (“1” or “0”).

Next, each processing of the incoming call connection method in the present embodiment using the electronic exchange will be described with reference to flowcharts shown in FIGS. 3 to 5 refer to FIG. 1 and FIG. Also, in the following, for the sake of simplicity of explanation, a case will be described in which terminal A shown in FIG. 1 is the transmitting side and terminal B is the receiving side.

As described above, according to the incoming call connection method in the present embodiment, when a call is made from the terminal A to the terminal B, the incoming call is rejected for a certain period of time, and after waiting for the rejection for a certain time, the incoming call is permitted. Is what you do. Hereinafter, such an incoming connection method will be referred to as “waiting incoming”.

First, when performing a queuing incoming call, which is the incoming call connection method in the present embodiment, registration that a queuing incoming call is made from the terminal B on the receiving side to the electronic exchange 1 is performed. When registering a waiting call from the terminal B, for example, after picking up the handset of the terminal B, a special number dial (a dial of a predetermined specific number) is dialed. When the terminal B is a multifunctional telephone, a specific key may be pressed instead of the special number dial.

[0013] Here, the case of registering a waiting incoming call will be described, but the registration is canceled by the same operation.
In order to make the following description easy to understand, it is assumed that a special number for registering a waiting incoming call is "41", and a special number for canceling the incoming call is "40".

When a special number is dialed by operating the terminal B, the central processing unit 5 of the electronic exchange 1 executes step S10 in FIG.
1 is performed. Next, as shown in step S102, the central processing unit 5 determines whether or not the dialed number sent from the terminal B is a special number for registering a waiting incoming call. For example, if the special number is "41", it is determined that the registration of the incoming call has been made,
If the special number is "40", it is determined that the waiting incoming call is released.

If it is a special number for registration of a waiting incoming call, the process proceeds to step S103. In this process, “1” is set to the waiting incoming call registration flag in the terminal memory 61. On the other hand, if it is not the special number for the registration of the waiting incoming call, the process proceeds to step S104. Then, step S10
In S4, it is determined whether or not this special number is a number for canceling the waiting incoming call.
Then, "0" is set to the waiting incoming call registration flag in the terminal memory 61.

On the other hand, if it is not the special number for canceling the waiting incoming call in the judgment in step S104, the process shifts to another transmission analyzing process. By the processing of the flowchart shown in FIG. 3, the registration and cancellation of the incoming call waiting can be set in the terminal memory 61 of the electronic exchange 1 by the operation from the terminal B.

Next, a description will be given of a process in the case where a connection for waiting incoming call is actually performed. First, when a call is made by dialing the telephone number of the terminal B from the terminal A, the central processing unit 5 of the electronic exchange 1 executes the processing of step S201 shown in FIG.
Is the terminal B stored in the terminal memory 61 of the main storage device 6.
The value of the waiting incoming call registration flag in the storage area of "1" is "1".
Is determined.

If the value of the waiting incoming call registration flag is "1", it means that the waiting incoming call has been registered, and the waiting timing shown in step S202 is registered. The timing of this meeting
This is the time for rejecting an incoming call from terminal A to terminal B.
That is, during the period of rejection of the incoming call, this time is registered in the timer 7 in order to connect to the guidance device 3 and to inform the terminal A of the waiting guidance.

Next, in step S203, the subscriber circuit 21 accommodating the terminal A, which is the transmitting side, and the guidance device 3 are connected by the switch 4, and the state transits to the guidance listening state. Here, the time for which the waiting guidance is to be heard is fixedly determined in advance, or is set and determined by a command from a maintenance console (not shown) of the electronic exchange 1.

When the guidance device 3 has a cueing function or is a high-performance device such as a voice mail device, it may involve capturing a channel or sending an order to the guidance device 3.

On the other hand, if the value of the waiting incoming call registration flag is "0" in the judgment of step S201, it means that the waiting incoming call has been released, and step S2 is executed.
As shown in FIG. 04, the subscriber circuit 2 accommodating the terminal A in order to hear the ring back tone to the terminal A on the calling side.
Connect the ringback tone to 1. Then, as shown in step S205, in order to ring the bell of the terminal B on the receiving side, the subscriber circuit 22 accommodating the terminal B is controlled to call the terminal B.

Next, processing after the waiting guidance listening state will be described. First, from the guidance listening state shown in step S301 in FIG. 5, it is determined whether the timeout or the calling side disconnection shown in step S302. In the waiting guidance listening state, the guidance is played while the timer 7 of the electronic exchange 1 is counting. As guidance, for example, a message such as "I am in a meeting now. If it is urgent, please wait for a while. If it is not urgent, please call again later."

In this state, when the central processing unit 5 receives the notification of the timeout from the timer 7, the process proceeds to step S303, in which the ringback tone is sent to the terminal A on the transmitting side, so that the subscriber circuit 21 accommodating the terminal A is received. In order to connect the ringback tone to the terminal B and call the terminal B on the receiving side shown in step S304, the subscriber circuit 22 accommodating the terminal B is controlled to call the terminal B,
Ring the bell.

When the terminal A is disconnected while the guidance is being listened to in step S301, the call is disconnected in step S302, and the guidance disconnection process shown in step S305 is performed. That is, assuming that the terminal A has no intention to call the terminal B, the communication path between the subscriber circuit 21 accommodating the terminal A and the guidance device 3 is disconnected, and the terminal A transits to an idle state.

With the above processing, the terminal B can
Even if the call is temporarily rejected in order to call, if an urgent contact is required from the terminal A, which is the originating side, waiting for a certain period of time allows the incoming call permission to be obtained.

For example, when the receiving party is in a meeting near the seat or is performing important work, there is a case where the user does not want to receive anything other than an emergency call. In such a case, if the waiting call registration is performed with respect to the electronic exchange 1 by the operation from the receiving side, the incoming call is rejected once for all calls, and the caller who does not need to urgently contact during that time. Does not ring the caller by canceling the call, while the caller who wants to contact urgently waits for a certain period of time and obtains permission to receive the call, and the called side rings at that stage Incoming call is received.

In this way, the calling side can call the calling side again later without having to bother the receiving side if the call is urgent, and can call the called side by waiting for a while if the call is urgent.

In the above-mentioned incoming call connection method, the time for listening to the waiting guidance is determined by setting a fixed value or a command from a maintenance console (not shown) of the electronic exchange 1. The time may be set in the waiting incoming call registration operation from the receiving side. In this case, following the special number dial for performing the incoming call registration, the time for listening to the guidance is designated by the dial and stored in the terminal memory 61.

In the process of step S202 shown in the flowchart of FIG. 4, when registering the waiting timing (time) in the timer 7, the time stored by the dial operation (or a value corresponding to the time) may be stored in the terminal memory 61. , And this time (in the case of a value corresponding to time, the time calculated from this value) is registered in the timer 7. This allows the receiving side to set the time during which the guidance is heard by the calling side.

Also, in the present embodiment, the terminal A
Can be applied to the case where is called an extension or the case where an outside line is called. Further, the contents of the waiting call registration may be changed depending on whether the call is an extension call or an outside call.

[0031]

As described above, according to the incoming call connection method of the present invention, the following effects can be obtained. In other words, even if registration of incoming call rejection has been registered, when calling the called terminal from the calling terminal, not all calls are rejected, but waiting for a certain period of time as necessary to obtain call permission And it is possible to make highly urgent contacts.
Thus, it is possible to satisfy the callee's request to receive only urgent communication and not to receive urgent communication, and to perform business smoothly.
