Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a telephone with a designated time automatic calling function applied to the field of telephone communication.

(Prior Art) In the private telephone systems of hotels and the like, an automatic call service by specifying a time is provided as a wake-up call. In other words, when you dial in the call service request code and designated time for calling from an extension telephone connected to a private branch exchange, the designated time and the extension number of the telephone that requested the service are registered in the host computer on the private branch exchange side. At the specified time, the host computer automatically calls the extension telephone.

(Problems to be Solved by the Invention) If the above-mentioned specified time automatic calling service is to be extended to general telephones for home use, etc., a function for this service must be added within the exchange, and the exchange There is a problem that the burden becomes excessive.

In addition, since in-office equipment is used when applying for and making an automatic call, the user of the telephone receiving the automatic call service must bear the cost, which can increase costs depending on the frequency of use. be.

(Means for solving the problem) The telephone with a designated time automatic calling function according to the present invention has the following features:
Based on the dial input from the dial board, the calling target, which may include the own telephone, another telephone designated by a telephone number, or both, and the calling start time are registered, and the registered calling target at the calling start time is the own telephone. If so, it will drive the ring tone generation circuit, and if the registered call target is another phone, it will automatically make a call using that phone number, and it will be specified at low cost and without placing any burden on the switching center. It is configured to realize automatic time calling.

Hereinafter, the operation of the present invention will be explained in detail together with examples.

(Embodiment) FIG. 1 is a block diagram showing the configuration of a telephone with a designated time calling function according to an embodiment of the present invention.

This telephone has a telephone circuit 11 connected to a telephone line.
In addition to general-purpose parts such as a handset 12, a dial board 13, and a ringing tone generation circuit 14, an automatic ringing control circuit 1 is provided.
5. Call number registration memory 16, designated time registration memory 1
7 and a timer 18.

If the user of this telephone wishes to call his own telephone or the telephone of another person, such as a friend, at a predetermined time, such as early in the morning,
A predetermined registration command code (such as #0) is dialed in advance from the dial board 13.

When the automatic call control circuit 15, which is composed of a microprocessor or the like, decodes the registration command code that is dialed in and appears on the signal line Sl, it starts the registration process shown in the flowchart of FIG.

The automatic call control circuit 15 first enters a waiting state for dial input (Step 21), and when it detects a dial input, it converts the detected MF signal string into a digital signal number string and stores it in the registration memory 16 as a call telephone number. Register (step 22). The automatic call control circuit 15 is
Registration continuation code (#, etc.) for the phone number that will be called later
When the input is detected (step 23), the process returns to step 21 to wait for the dialing input of the next calling telephone number to be registered, and the same registration process is repeated for this as well.

When the automatic call control circuit 15 detects an end code (such as ##) in step 23, it enters a waiting state for the next dial input (step 24). When the automatic call control circuit 15 detects the dial input in step 24, the automatic call control circuit 15 converts this MF signal string into a digital signal string and registers it in the designated time registration memory 17 as the designated call time (step 25). When the automatic call control circuit 15 detects the input of a registration continuation code (such as #) for the designated call time (step 26), the automatic call control circuit 15 returns to step 24, waits for the input of the next designated call time to be registered, and waits for the input of the next designated call time to be registered. The same registration process is repeated for .

When the automatic call control circuit 15 detects an end code (such as ##) in step 26, it ends all registration processing for automatic call at a specified time.

After the above registration process is completed, the automatic call control circuit 15 repeats the automatic call process shown in the flowchart of FIG. 3 at a predetermined cycle based on a timer interrupt or the like.

That is, the automatic call control circuit 15 first reads the memory 17.
The designated call time registered in the timer 18 and the time displayed on the timer 18 are read out and compared.Steps 31 and 32) If the comparisons do not match, this automatic reading process is immediately terminated.

If the times match in step 32, the automatic call control circuit 15 reads out the first call number registered in the call number registration memory 16 (step 33);
Determine whether this is your phone number (
Step 34). The automatic call control circuit 15 transmits a control signal line S3 if the registered telephone number is the telephone number of the own telephone.
Activate the ringing tone generating circuit 14 by step 35.
), waits for a response from the user of this telephone (step 37).
. When the automatic ringing control circuit 15 detects the user's response by off-footer of the handset 12 through the control signal line S4 (step 37), it stops the operation of the ringing tone generating circuit 14 through the control signal line S3 (step 38).
Subsequently, the automatic call control circuit 15 reads data in the next registration area of the call number registration memory 16 (step 39), and if this registration data exists, the process returns to step 34.

If the calling telephone number read from the registration memory 16 is not the telephone number of the own telephone, the automatic calling control circuit 15 automatically calls another telephone by transmitting this calling telephone number onto the telephone line (step 36). . That is, the automatic call control circuit 15 puts the telephone in an off-hook state by operating the switch 19 via the control signal line S2, and waits for a dial tone sent from the exchange that has detected this off-hook state. Automatic call control circuit 1
5 confirms the dial tone from the exchange, converts the called telephone number into an MF signal, and sends it out over the telephone line via the signal line s1 and the telephone circuit 11.

In this case, the automatic call control circuit 15 waits for a response from the other party's telephone, such as by stopping the ringback tone (step 37), and upon confirming the other party's response, restores the telephone by operating the switch 19 via the control signal line S2 ( Step 38).

When the automatic call control circuit 15 detects in step 40 that the next call telephone number is not registered in the registration memory 16, it ends all automatic call processing at this designated time.

The configuration above has been exemplified in which automatic calling to the own telephone is also performed by registering the telephone number.

However, automatic calling to the own telephone may be performed by registering a predetermined calling command code instead of the telephone number.

In addition, when the response from another telephone is confirmed in step 37 of FIG. 3, if the handset 12 of the own telephone is off-hook, the self-telephone can be restored by waiting for it to go on-hook and performing the recovery process in step 38. It may also be configured to allow telephone calls between the user of the telephone and the users of other telephones.

Furthermore, a configuration is illustrated in which the calling continues until the called party's response is confirmed. However, the automatic call control circuit 15 may be configured to automatically terminate the automatic call after a certain period of time without providing the automatic call control circuit 15 with a function for checking the response of the called party.

(Effects of the Invention) As explained in detail above, the telephone with the specified time automatic calling function of the present invention registers the calling targets including the own telephone and other telephones and the calling start time, and at the calling start time. If the registered calling target is your own phone, it will drive its ring tone generation circuit, and if the calling target is another phone, it will automatically make a call based on that phone number, so there is no burden on the switching center side. It is possible to realize the automatic call function at a specified time without having to apply time.

Furthermore, the automatic calling function for a designated time can be realized at low cost without using a telephone line for automatic calling to one's own telephone.
