Abstract

PURPOSE:To prevent an opposite destination who has been communication reservation-registered lately from being recalled by releasing the registration of communication reservation when there is an incoming call from an opposite who has been communication reservation-registered and when the opposite who has been communication reservation-registered is called. CONSTITUTION:A control part 2 receives a dial signal from a telephone set 7 through an extension interface 5, and executes the busy processing of the transmission of busy sound when an extension opposite is busy. When the extension opposite is not busy, a memory 3 is referred to and the registration of the memory 3 is released if he himself makes ringing off waiting registration for the opposite. Finally, a call processing is executed. When communication is made with the opposite to whom the registration of communication reservation is made not by a communication reservation function, the registration of communication reservation is released, and the opposite with whom communication is made immediately before is prevented from being called again by the communication reservation function when communication terminates.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a communication method for a communication device having a communication reservation function.

[Conventional technology]

Conventionally, this type of device has, for example, a camp-on function (
With a private branch exchange that has a call reservation registration function), if the other party on the extension line is busy and you go on-hook after performing a specific operation (Camp-on registration), when the other party ends the call, the phone that registered Camp-on will be connected to the other party's phone. It is configured to play a ringback tone and call the original party when you go off-hook.

[Problem that the invention is trying to solve] However,
In the conventional example above, if you go on-hook after registering Camp On and are waiting for a call back, and you receive a normal call from the other party who has registered Camp On, you answer the call, talk to the other party, and go on hook together. There is a problem in that the phone that has been registered on will have a ringback tone, and if you go off-hook, the phone you just called will be called again.

[Means for solving problems]

The present invention is intended to solve the above-mentioned problems, and as one method for solving the above-mentioned problems, in one embodiment of the present invention, when there is an incoming call from a party who has registered a call reservation, The registration of the communication reservation is canceled when the called party is called.

[For production]

According to the present invention, when communication is performed by some method with a party with whom a communication reservation has been registered, it is possible to prevent the party with whom a communication reservation has been registered from being called again.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention.

In FIG. 1, l is a private branch exchange, 2 is a control unit that controls the private branch exchange, 3 is a memory that stores data necessary for exchange, and 4 is a communication path SW that connects/disconnects the communication path between an outside line and an extension line. , 5 is an interface unit for connecting an extension telephone, 6 is an external line interface unit, 7 is an extension telephone,
8 is an outside line.

FIG. 2 shows the operation flow of the control section 2 when an extension calling signal is received from the telephone 7 via the extension interface 5 in the above configuration.

In FIG. 2, first, in step Sl, a dial signal (extension number) is received from the telephone 7 via the extension interface 5. In step S2, it is determined whether the extension partner specified by the extension number is busy (talking), and if it is busy, the process moves to step S8, and busy processing such as sending out a busy tone is performed. If the other party on the extension line is not busy, the process moves to step S3, and memory 3 is referred to to determine whether or not the other party is registered as a waiting list. Release. Next, the process moves to step S5, and the memory 3 is referred to to determine whether or not the other party's extension has registered itself as a waiting list. If so, the registration in the memory 3 is canceled in step S6. Finally, the process moves to step S7 to perform call processing such as ringing and RBT (ringing tone) transmission.

In the above embodiment, the registration of camp-on is canceled when the other party's extension is called, but it may be canceled when the other party's extension is connected and a call is made.

〔Effect of the invention〕

As explained above, according to the present invention, even if you communicate with a party with whom you have registered a communication reservation without using the communication reservation function, the registration of the communication reservation is canceled and the communication reservation is canceled when the communication is terminated. This function has the effect of preventing you from calling up the person you previously communicated with again.

[Brief explanation of the drawing]

FIG. 1 is a configuration diagram of an embodiment according to the present invention, and FIG.
FIG. 3 is an operation flowchart of the control section of the embodiment. In the figure, 1 is a private branch exchange, 2 is a control unit, 3 is a memory, 4 is a call path SW, 5 is an extension line interface, 6 is an outside line interface, 7 is a telephone, and 8 is an outside line.

Claims (1)

[Claims] In a communication device having a communication reservation function, when communicating with a destination with which a communication reservation has been registered without relying on the communication reservation, the communication reservation is canceled.
