Abstract

PURPOSE:To control an incoming call which is called regardless of the intention of a callee by the intention of the callee. CONSTITUTION:An incoming call subscriber 2 preliminarily registers an incoming call control time, and a calling subscriber's number which is specially permitted even within the incoming call control time, through an incoming call registration control circuit 4 connected with a peripheral device 1 in a memory 6 by a PB signal. When the incoming call from the subscriber whose incoming call is not permitted, is almost called within the decided time, the registered data in the memory 6 are collated with a present time by a timer 5, and the subscriber's number of this subscriber by a comparator 7, and a message indicating the incoming call control is transmitted from an announcement circuit 8 to the calling subscriber instead of calling the callee subscriber 2.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incoming call connection regulation method for an exchange.

0002

2. Description of the Related Art Conventional switching equipment calls a called party only in accordance with the will of the caller and performs call connection processing.

0003

[Problems to be Solved by the Invention] Conventional exchanges call incoming calls and connect calls only according to the will of the caller, so the will of the called party is ignored, and unspecified callers Another disadvantage is that the callee may be called even at unspecified times, such as late at night, which may annoy the callee.

0004

[Means for Solving the Problems] The incoming call connection regulation method of the present invention accommodates subscribers of an exchange, receives information from the subscribers and information from a host device, and controls calls of the subscribers. a timer that outputs the current time; a memory that records an incoming call allowed caller number and an incoming call restriction time; an incoming call registration control circuit that receives the caller number received by the incoming call registration control circuit and registers it in the memory, and receives the caller number for the incoming call from the host device; a comparator that collates the recorded incoming call permission caller number, collates the current time according to the timer and the incoming call restriction time recorded in the memory, and notifies the peripheral control device of the collation result; and an announcement circuit that outputs an incoming call restriction message to the peripheral control device according to instructions from the comparator.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of one embodiment of the present invention. The peripheral control device 1 is connected to the network as a higher-level device and accommodates a receiving subscriber 2 on the lower-level side. An incoming call connection regulation device 3 is further connected to this peripheral control device 1. Further, when there is an incoming call to the incoming subscriber 2, it is assumed that the calling party number is sent from the network to the peripheral control device 1 together with the incoming subscriber number.

This incoming call connection restriction device 3 includes an incoming call registration control circuit 4 having an interface with the peripheral control device 1, a timer 5 for recognizing the current time, and recording the incoming call permitted caller number and incoming call restriction time. memory 6 and memory 6
a comparator 7 that compares the incoming call permitted caller number and incoming call restriction time stored in the network with the caller number coming from the network and the current time according to the timer 4, and an announcement circuit that contains a message reporting that incoming calls are being restricted. It consists of 8.

Next, the operation will be explained.

[0009] First, in order to receive this service in advance, the receiving subscriber 2 registers an incoming call permission subscriber number (caller number) and incoming call restriction time using a PB signal. The registration signal is sent from the called subscriber 2 to the called call registration control circuit 4 via the peripheral control device 1. Then, the incoming call registration control circuit 4 writes the contents (incoming call permission subscriber number and incoming call restriction time) into the memory 6. This completes the registration of the subscriber who is allowed to receive calls and the restricted time for receiving calls.

Next, assume that the receiving subscriber 2 receives a call from a subscriber who is not allowed to receive calls at the call restriction time. The caller's number is sent from the upper network device to the peripheral control device 1 along with the called subscriber's number. Peripheral control device 1
transfers the contents of this signal to the incoming call registration control circuit 4. In the incoming call registration control circuit 4, the current time information is sent to the timer 5.
, and sends the time information and caller number to the comparator 7, and also instructs the comparator 7 to send the incoming call restriction time registered by the receiving subscriber 2 and the number of the permitted caller from the memory 6. do. In the comparator 7, since it is the incoming call restriction time and the subscriber is not registered as a subscriber who is permitted to receive incoming calls, it is impossible to determine the connection, so the comparator 7 does not perform the process of calling the incoming subscriber, and reports the result of not being possible to the peripheral control device 1. An announcement output instruction is issued to the announce met circuit 8. Then, an announcement signal is output from the announcement circuit 8 to the peripheral control device 1, and a path is set within the peripheral control device 1 so that the announcement output signal is sent to the subscriber who is not allowed to receive calls. Then, the non-terminating subscriber receives a message that the incoming call is being restricted.

[0011] When a call is received from a caller who is permitted to receive calls outside of the call restriction time or during the call reception restriction time, the comparator 7 allows connection, and the result is sent to the peripheral control device 1. Therefore, the peripheral control device 1
Perform the process of calling.

0012

[Effects of the Invention] As explained above, the present invention connects an incoming call from a non-permitted originating subscriber within the incoming call restriction time registered by the terminating subscriber to an incoming call restriction announcement without calling the terminating subscriber. Therefore, it is possible to block incoming calls from subscribers other than those specified by the receiving subscriber, and has the effect of blocking nuisance calls that come in late at night, prank calls, etc.
