Abstract

PURPOSE:To prevent the violation of the privacy of a receiving subscriber by being equipped with an incoming regulation data memory in an exchange, registering the incoming regulation data to the memory with a receiving person and executing the receiving person leading type incoming regulation. CONSTITUTION:In a main memory device 3 of an exchange, a incoming regulation data registering memory 9 is provided in which incoming regulation data 20 including a subscriber memory 8, a subscriber number 21, an incoming regulation starting time 22, a receiving regulation completing time 23, and a regulation class 24 are written for a incoming regulation offering subscriber. In the memory 8, a regulation bit, which comes to be '1' during the incoming regulation and '0' during the non-regulation, is provided. An one-second ringer 7 executes the present incoming regulation to a subscriber for the receiving during the regulation time and sends an one-second calling sound to inform of the receiving. A tone generator 6 generates a seal tone to inform a transmitting person of the effect that the regulation is executed. A control means releases the above- mentioned registration with a special number and an emergency incoming call has a control function connected even during the incoming regulation.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to automatic telephone exchanges.

(Prior Art) Traditionally, telephone services have been caller-initiated, where calls are made at the caller's will and the calls are terminated unless the called party is line-based.

(Problems to be Solved by the Invention) The conventional telephone service described above is caller-initiated based on the caller's will, and the call is received regardless of the callee's intention, so the privacy of the callee may be violated. It has the disadvantage of being

[Means for solving problems]

The automatic telephone exchange with the incoming call restriction service function of the present invention stores the incoming call restriction data registration memory in the incoming call restriction data registration memory. Register the data of number and incoming call restriction start and end time, and during the registered incoming call restriction/i period, turn on the bit indicating that incoming call restriction is in progress in the status display area of the registered subscriber in the subscriber memory, and incoming calls during this period. For incoming calls, a tone or announcement indicating that the subscriber is under incoming call restriction is connected, and when the registered subscriber dials a special number predetermined to cancel the incoming call restriction registration, the incoming call restriction data memory is sent. The emergency incoming call made by the predetermined calling method is connected even during the incoming call restriction service time.

[For production]

Therefore, the subscriber can freely register in the telephone exchange the time period during which incoming calls are restricted to avoid incoming calls, and moreover, can receive emergency calls, and can also freely cancel the incoming call restriction registration.

〔Example〕

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of an automatic telephone exchange with Wakai 3 restriction function of the present invention, FIG. 2 is a detailed diagram of the incoming call restriction data registration memory 9, and FIG. 3 is a flowchart showing the operation of this embodiment. It is.

The main storage device 3 includes a subscriber memory 8 and call restriction data 20 including a subscriber number 21, an incoming restriction start time 22, an incoming restriction end time 23, and a restriction class 24 by dialing the subscriber. An incoming call restriction data registration memory 9 is provided which is written every time a call is received. Subscriber memory 8
An incoming call restriction bit is provided for each subscriber, which is "1" when incoming calls are restricted and is "0" when incoming calls are not restricted. When a call arrives during the incoming call restriction time, the one-second ringer 7 sends out a one-second ring tone to inform the subscriber under incoming call restriction that the incoming call is currently restricted and that there is an incoming call. The tone generator 6 generates a pillow tone to notify the caller that incoming calls are being restricted. The dialing procedure for incoming call restriction registration and deregistration is as follows.

Incoming Call Restriction Registration 3: Other Incoming Call Restriction Registration Cancellations Therefore, for example, if you want to register an incoming call restriction service where the incoming restriction start time is 11:00 p.m., the incoming restriction end time is 6:30, and the incoming restriction class is only for emergency calls. Just dial r X Y Z 230006302 J. Also, if you want to cancel the registered incoming call restriction,
All you have to do is dial the special numbers X and PQ for canceling the incoming call restriction registration from the telephone.

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

When the subscriber dials according to the incoming call restriction registration procedure, incoming call restriction data 20 is stored in the incoming call restriction data registration memory 9 of the main storage device 3. When the incoming call restriction start time comes, the incoming call restriction bit of the subscriber in the subscriber memory 8 becomes "1". When a call arrives to a subscriber in this state, it is determined whether or not the incoming call is restricted at the stage of checking the subscriber state in the subscriber memory 8 (step 11); in this case, the incoming call restriction bit is set to "1". ” Therefore, it is determined that the incoming call is being restricted, and the tone generator 6 sends back a pillow tone to the caller indicating that the incoming call is being restricted (step 12), and a 1-second ringtone is sent to the called subscriber whose incoming call is being restricted. is sent out from the ringer 7 for one second (Step!3). When the incoming call ban ends,
Alternatively, when the special number for deregistering the incoming call restriction is dialed, the incoming call restriction data 20 of the subscriber is canceled, and the incoming call restriction bit in the subscriber memory 8 is also set to "0". Therefore, when the subscriber status is checked against the subscriber memory 8 at the time of receiving a call (step 11), it is determined that the incoming call is not restricted, and a normal call is received (step 1).
4).

〔Effect of the invention〕

As explained above, the present invention provides an incoming call restriction data memory in the exchange, the called party registers the incoming call restriction data in this memory, and performs called party-driven incoming call control, thereby protecting the privacy of the called subscriber. It has an effect that cannot be violated.

Claims (1)

[Scope of Claim] In an automatic telephone exchange accommodating a subscriber terminal, an incoming call restriction data registration memory; Register the subscriber number and data on the start and end time of incoming call restriction, and during the registered incoming call restriction time, turn on the bit indicating that incoming call restriction is in progress in the status display area of the registered subscriber in the subscriber memory. For incoming calls, a tone or announcement is connected to indicate that the subscriber is under incoming call restriction, and when the registered subscriber dials a special number predetermined to cancel the incoming call restriction registration, the incoming call is restricted. An automatic telephone exchange with an incoming call restriction function, characterized in that the automatic telephone exchange has a control means that cancels the registration of the data memory and connects an emergency incoming call made by a predetermined calling method even during the incoming call restriction service time. .
