[0021]
The user of the receiving-side communication terminal device 103 operates the dial key and the caller information inquiry key of the operation unit 212 when an unrecognized telephone number or a suspicious telephone number remains in the received call history. A request for notifying whether the number is the source of the nuisance call, that is, a request for notification of the source information, is transmitted to switching apparatus 102. When receiving the notification request of the source information from the receiving-side communication terminal device 103, the control unit 311 of the switching apparatus 102 determines the telephone number of the notification request based on the information stored in the subscriber information storage unit 312, thereby causing an inconvenience. It is determined whether or not the caller is the caller, that is, the source of the nuisance call is specified. Then, the result is stored in the subscriber information storage unit 312 as the source information of the nuisance call, and is notified to the receiving-side communication terminal device 103 that has sent the notification request.
[0022]
Hereinafter, the procedure for specifying the source of the nuisance call will be described with reference to the flowchart of FIG. When the control unit 311 of the switching apparatus 102 receives the notification request of the transmission source information from the receiving side communication terminal apparatus 103, first, the information stored in the subscriber information storage unit 312 within a predetermined period of the corresponding telephone number is obtained. Get all the information on the calling time of. Then, the number of calls (N1) whose calling time is shorter than the threshold 1 is counted (step S401), and subsequently, the number of calls (N2) whose calling time is longer than the threshold 1 is counted (step S402). Note that the threshold value 1 is a time for one call and two calls.
[0023]
Thereafter, the number of calls (N1) in which the call time is shorter than the threshold 1 is compared with the threshold 2 (step S403). If N1 is equal to or larger than the threshold 2 (YES in step S403), the caller transmits a call with a short call time. It is determined that a large amount has been performed (step S404). If N1 is less than threshold 2 (NO in step S403), the ratio (N1 / N2) between the number of calls (N1) whose call time is shorter than threshold 1 and the number of calls (N2) whose call time is longer than threshold 1 and the threshold 3 is compared (step S405). As a result, if the ratio (N1 / N2) is equal to or greater than the threshold value 3 (YES in step S405), it is determined that the caller has made a number of calls with a short calling time (step S406). If the ratio (N1 / N2) is less than the threshold value 3 (NO in step S405), it is determined that the caller has not made many calls with a short calling time (step S407).
[0024]
As described above, according to the communication terminal device and the communication system of the present embodiment, the user of the receiving-side communication terminal device 103 determines whether or not the telephone number remaining in the incoming call history is "one-ring".

If an unknown or suspicious telephone number remains in the incoming call history, the telephone number is specified and a notification request of the transmission source information is transmitted to the switching apparatus 102, whereby the determination by the switching apparatus 102 is performed. Since the result can be known, it can be more accurately determined whether or not the corresponding telephone number is based on “one-ring”.
[0025]
In addition, the communication service provider or the like can determine the source of frequent “one-time call” based on the source information of the nuisance call stored in the subscriber information storage unit 312 of the switching device 102. . Accordingly, it is possible to prevent the spread of the damage caused by the "one-round" by disclosing the source information of the nuisance call or detecting the source.
[0026]
In the above-described embodiment, the process of identifying the source of the nuisance call in the switching device 102 is performed after waiting for a notification request of the source information of the nuisance call from the receiving communication terminal device 103. Regardless of the presence or absence of the notification request, the process of specifying the source of the nuisance call is performed, the information is stored in the subscriber information storage unit 312, and the incoming call history including the telephone number of the corresponding source is notified. Alternatively, the receiving side communication terminal device 103 may be notified that the caller is the source of the nuisance call.
[0027]
【The invention's effect】
As described above, according to the communication terminal device of the present invention, not only the telephone number but also the calling time at the time of the incoming call is displayed as the incoming call history, so that the user can check the telephone number remaining in the incoming call history. It is possible to easily determine whether or not the possibility of “one-cut” is high.
[0028]
Further, according to the communication system of the present invention, the user of the communication terminal apparatus can determine whether or not the telephone number remaining in the incoming call history is based on “one-ring” and display the call time together with the telephone number. Can be determined on the basis of the transmission source information stored in the switching device. Also, the user of the communication terminal device can know the source of the nuisance call identified in the switching device by transmitting a notification request of the source information to the switching device, so that the telephone number remaining in the received call history can be obtained.
