Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a telephone system connected to a private branch exchange or a general public telephone line network, and having a range-designating calling function.

[0002]

2. Description of the Related Art Conventionally, a telephone device having a function of receiving an empty extension within a certain range has been provided. In this case, which extension number is to be called is set by the called side. , It could not be set on the calling side.

For example, in the telephone system shown in FIG. 8, when it is desired to make a call from an extension of the telephone set A1 to an empty extension of the other telephone sets B1 to B4, B0 is set as a representative number of the other telephone sets B1 to B4. , A call was made to the representative number B0 from the telephone A1.

[0004]

As described above, in the case of an incoming call to an empty extension, if the representative number is not set, the called party cannot specify the called party.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a telephone system with a range-designating calling function capable of making a call for automatically searching for an empty extension according to the intention of the calling side. It is in.

[0006]

In order to solve the above problems, a telephone system with a range-designating calling function according to the present invention is used when a telephone call is made to a private branch exchange or a telephone connected to a general public telephone network. Number designating means for designating the lower and upper limits of the other party's telephone number, first storing means for storing the lower party's telephone number of the lower party designated by this number designating means, and upper limit of the upper limit designated by the number designating means. Second storage means for storing the other party's telephone number, within the range of the lower limit other party's telephone number stored in the first storage means and the upper limit other party's telephone number stored in the second storage means In the case of making a call to any other party's telephone number in, and making a call to the next arbitrary other party's telephone number while the telephone number is busy, the operation is performed until the other party becomes the calling state. Or A structure in which a repeated control unit for all the telephone numbers of 囲内.

[0007]

In the calling side, when making a call, the lower limit and the upper limit of the other party's telephone number are first designated by the number designating means. For example, 2200 is specified as the lower limit of the other party's telephone number, and 2205 is specified as the upper limit of the other party's telephone number. That is, the calling operation is performed for 6 lines 2200 to 2205. The lower limit 2200 of the other party's telephone number is stored in the first storage means, and the upper limit 2205 of the other party's telephone number is stored in the second storage means.

After that, when the call key is pressed, the control unit performs a call operation to, for example, 2200 which is the lower limit of the other party's telephone number. When a busy tone is sent in response to this calling operation, the control unit next sets the lower limit of 2200 lower 1
A call operation is performed for 2201 in which 1 is added to the digit. Then, when the busy tone is sent again for this calling operation, the control unit next increments the last digit of the telephone number 2201 by one.
Calling operation is performed to 2202 added with. The control unit
Such a calling operation is repeated until a ringing tone is sent from the other party or until the calling operation for the upper limit 2205 is performed. Then, when a ringing tone is sent for an arbitrary calling operation, the calling operation for the telephone number is continued. In addition, when a busy tone is sent in response to a call operation to the upper limit 2205,
At that point, the calling operation is stopped.

In this way, the caller does not need to be aware of the presence or absence of the representative number, and among the telephone numbers within the desired range (for example, the telephone number of a certain department), the vacant telephone number. You can make an incoming call to your telephone. Therefore, the probability of being busy for a call is reduced, work efficiency can be improved, and the number of redial calls is reduced, so that the load on the exchange can be reduced.

In the figure, each telephone A1, B1 to B4
A central processing unit 32, which controls the operation of the entire exchange, is bidirectionally connected to a dedicated telephone interface 31 which is connected to each of the central processing units 3 and 4.
2, a status memory unit 33 for storing the status (on-hook, off-hook, etc.) of each of the telephones A1, B1 to B4.
To 37 are bidirectionally connected. Further, the central processing unit 32 stores a first storage unit 38 for storing the upper limit of the other party's telephone number when making a call, a second storage unit 39 for storing the lower limit of the other party's telephone number, and the actual call origination. Third storage units 40 for storing telephone numbers for making calls are bidirectionally connected.

Next, the operation of the telephone system having the above configuration will be described.
This will be described with reference to the flowcharts shown in FIGS. 6 and 7.

The status of each of the telephones A1 and B1 to B4 is sent to the central processing unit 32 via each station line and the dedicated telephone interface 31, and stored in each of the corresponding status memory sections 33 to 37 provided. It For example, in FIG.
In the example shown in (1), it is stored in each of the status memory units 33 to 37 that the telephone sets A1, B1, B2 and B4 are in the on-hook state and the telephone set B3 is in the off-hook state.

In this state, when the user operates the key input section of the telephone set A1 to input a dial number, this dial number is given to the central processing unit 32 via the station line and the dedicated telephone interface 31. , And are stored in the first storage unit 38 (steps S21 and S22). That is, the dial number stored in the first storage unit 38 (for example, the dial number 220 given to the telephone set B1).
1) is the lower limit dial number. At this time, telephone A
The off-hook state is stored in the status memory unit 33 corresponding to 1.

After that, when the user operates the call key of the key input section of the telephone set A1 (step S23), the central processing unit 32 follows the key input signal, and makes a call operation similar to the conventional one, that is, the first storage section. A call is made to the dial number stored in 38 (step S24). Then, after the other party's telephone answers, it becomes a call state (step S3).
5).

On the other hand, after the dial number is input, the range key of the key input section of the telephone set A1 is operated without operating the call key, and when the user thereafter inputs the dial number, this dial The number is given to the central processing unit 32 via the station line and the dedicated telephone interface 31, and stored in the second storage unit 39 (step S23,
S25, S26, S27). That is, the dial number stored in the second storage unit 39 (for example, the telephone B4
The dial number 2204) given to the user becomes the upper limit dial number.

Thereafter, when the user operates the call key of the telephone A1 (step S8), the central processing unit 3
2 reads the dial number stored in the first storage unit 38 and stores it in the third storage unit 40 (step S29). After that, the central processing unit 32 searches the contents of the status memory unit 34 corresponding to the dial number (2201) stored in the third storage unit 40, and if the dial number (2201) is in the on-hook state, Then, the transmission operation is performed (steps S30 and S34). And
In response to this calling operation, telephone B1 of the dialed number
Is answered, the call state is established (step S35).

On the other hand, in the judgment at step S30,
The dial number stored in the third storage unit 40 (220
When the content of the status memory unit 34 corresponding to 1) is in the off-hook state, the central processing unit 32 causes the lower 1 of the dial number (2201) stored in the first storage unit 38 to be displayed.
220 is calculated by adding 1 to the digit and adding 1
The dial number 2 is stored in the third storage unit 40 (step S31). After that, the central processing unit 32 causes the dial number (220) stored in the third storage unit 40 to be stored.
The contents of the status memory unit 35 corresponding to 2) are searched (step S30), and then the processes of steps S31, S32 or S34, S35 are performed based on the search result. Then, in step S32, the dial number stored in the third storage unit 40 is stored in the second storage unit 39.
Repeatedly until it matches the upper limit dial number stored in, and when a busy tone is sent at the dialing of any dial number, the central processing unit 32 determines that all the telephones within the range are busy. If it is determined that there is a busy process (step S33), the calling operation ends.

After the transmission operation is completed, the third storage unit 4
The dial number stored in 0 is cleared, and the dial numbers stored in the first storage unit 38 and the second storage unit 39 are saved for redialing.

In each of the above-described embodiments, the dialing operation starts from the lower limit dial number and reaches the upper limit dial number. However, the calling operation starts from the upper limit dial number and reaches the lower limit dial number. It is possible to do so. It is also possible to start the calling operation from any dial number within the lower and upper limits.

[0033]

According to the telephone system with a range designation type calling function of the present invention, the lower and upper limit telephone numbers of the other party's telephone number at the time of making a call are designated, and the telephone number is called from any other party's telephone number within the range. Since it is configured to make calls one after another until a sound is sent, the caller can make an incoming call to an available one of the phones within the desired range without being aware of the presence or absence of the representative number. .. As a result, the probability of being busy is reduced, improving business efficiency and
Since the number of redials is reduced, the load of the exchange can be reduced.
