Abstract

PURPOSE: To provide various services by an elastic incoming call screening by sending an emergency call in the case where a service user receives incoming calls at a higher frequency than one be decides in advance. CONSTITUTION: A sender's number 7 and callee's number 8 of an incoming call are inputted in a controller 1 which performs the incoming call screening processing. The controller 1 compares the sender's number of a part 5 setting and comparing the sender's number at a callee user data part 3 of the inputted callee number 8 with the inputted sender's number 7. When they are matched, a positive answer is outputted. When they are not matched, the sender's number and the incoming time are recorded as an incoming long in an incoming log storage part 6. With an incoming frequency response grade 4 registering the time frequency and the incoming log of the inputted sender's number 7 in the part 6, a positive answer is outputted if the incoming call is higher than the registered incoming frequency response grade 4. If it is lower than that, a negative answer is outputted.

Further, the incoming call screening apparatus of the present invention compares the calling party number registered in the called party user data section for each called party number with the inputted calling party number, and the comparison result is matched. For example, in the device for screening an incoming call in the telephone exchange service that outputs an affirmative answer, means for inputting the calling party number and the incoming time of the incoming call whose comparison results do not match in the incoming call history storage section of the called party user data section. And the incoming call frequency sensitive grade that represents the incoming call frequency within the time period registered for comparison and the incoming call history of the input calling party number in the incoming call history storage section If so, it has means for outputting an affirmative answer, and means for outputting a negative answer if the incoming call is less than the incoming call frequency sensitive grade.

Also, the incoming call frequency sensitive grade is a first incoming call frequency sensitive grade which is a comparison value for comparing the number of hours for obtaining the specific incoming call number before the current time with the specific incoming call number. Have.

Further, the incoming call frequency sensitive grade has a number of hours for obtaining the number of incoming calls after a specific time and a second incoming call frequency sensitive grade which is a comparison value for comparing with the specific incoming call number. .

Further, the incoming call frequency sensitive grade includes the first incoming call frequency sensitive grade and the second incoming call frequency sensitive grade.

[0010]

According to the present invention, the calling party number registered in the called party user data section for each called party number is compared with the inputted calling party number, and the calling party number of the incoming call that does not match is compared. The incoming call time is entered in the incoming call history storage section of the receiving side user data section, the incoming call frequency sensitive grade registered in advance is compared with the incoming call history of the input calling party number in the incoming call history storage section, and the incoming call frequency is calculated. If the number of incoming calls is higher than the sensitive grade, an affirmative answer is output, and if the number of incoming calls is lower than the incoming call frequency sensitive grade, a negative answer is output and is recorded in the incoming call history storage unit.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram of an embodiment of the present invention, FIG. 2 is a diagram showing a configuration of an incoming call frequency sensitive grade, and FIG. 3 is a flow chart of operation of an embodiment of the present invention.

As shown in FIG. 1, the present invention comprises a control device 1 for performing an incoming call screening process, and a recording device 2 for storing a destination user data section 3 which is referred to when executing the incoming call screening process. . Each destination user data unit 3 has a first or second incoming call frequency sensitive grade 4 of the incoming call for setting and comparing the incoming call frequency for comparison, and a calling party number capable of setting zero or more calling party numbers. It comprises a setting comparison section 5 and an incoming call history storage section 6 for recording the incoming call history of incoming calls.

The incoming call frequency sensitive grade 4 in the destination user data section 3 is the same as the calling party number setting comparison section 5 for users of the switching service using the incoming call screening device, for example, the call transfer service in the telephone switching service. It can be set by a called subscriber. As shown in FIG. 2, the incoming call frequency sensitive grade 4 is composed of GRa and GRb, and both GRa and GRb are zero or positive integer values and have the following meanings.

GRa = n (n is a positive integer) means that when the incoming call frequency of a specific calling party number is compared as the first incoming call frequency sensitive grade, n hours before the current time when the comparison is executed. It is the number of hours until the specific start time when the second incoming call frequency sensitive grade is compared.

GRa = 0 means before the current time when the comparison is performed when comparing the incoming call frequency with the first incoming call frequency sensitive grade.

GRb = m (m is zero or a positive integer) is
It means a comparison value used when comparing the incoming call frequency with the first or second incoming call frequency sensitive grade.

Next, the operation of the incoming call screening apparatus of the present invention will be described with reference to FIGS. 1 and 3.

When the calling party number 7 and the called party number 8 of the incoming call are input to the controller 1, the controller 1 sets the calling party number setting in the called party user data section 3 of the entered called party number 8. The calling party number registered in advance in the comparing section 5 is compared with the inputted calling party number 7. If they match, an affirmative answer is output, and if they do not match, the calling party number and the incoming call time are stored in the incoming call history storage section 6. Record as an incoming call history.

Next, from the incoming call history consisting of the calling party number and the incoming time in the incoming call history storage unit 6, the first or second
Of the incoming call frequency-sensitive grade 4 GRa, the number of incoming calls of the input calling party number 7 within the time specified, was compared with the first or second incoming frequency-sensitive grade 4 GRb. If the number of incoming calls is GRb or more, an affirmative answer is output, and if the number of incoming calls is less than GRb, a negative answer is output.

The destination user data section 3 has a first incoming call frequency sensitive grade and a second incoming call frequency sensitive grade, and can be switched by the control device 1.

Further, when the incoming call screening device of the present invention is installed on the exchange side, the destination user data section 3 stored in the recording device 2 is subscribed to the service using the device of the present invention. It becomes the number of users, and when installed on the terminal side, it is natural that the number of receiving side user data units 3 stored in the recording device 2 is one.
