DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device such as a portable telephone, and more particularly to a communication device having a function of recording incoming information.

[0002]

2. Description of the Related Art In recent years, a communication device such as a portable telephone generally has a function of recording, for example, an incoming telephone number and an incoming call date and time as incoming information when there is an incoming call. By recording the incoming call information, the user can know whether there is an incoming call that did not answer, and when and from which number the incoming call that did not answer was received. The user recognizes this incoming information using a liquid crystal display device or the like usually provided in the communication device.

[0003] In addition to the function of recording incoming information,
Communication devices that can register a telephone number and information related to the telephone number, such as the name of the owner, in advance as telephone directory information are also widely used. In such a communication device, when the incoming telephone number recorded in the incoming call information matches one of the telephone numbers registered as the telephone directory information, the user may be notified of information related to the telephone number together with the incoming call information. it can.

[0004]

However, in recent years,
Making use of the fact that communication devices have almost the standard function of recording incoming information as described above, the telephone number is recorded as incoming information by setting the communication device to an incoming state for a very short time (hereinafter, referred to as This action is referred to as "one-off", and malicious mischievous telephone calls are made to expect that a user who has recognized the incoming call information will call back the incoming telephone number.

When the telephone number recorded as the incoming call information is a telephone number registered in advance as telephone directory information, the telephone directory information is added and displayed together with the incoming call information. It's not a phone number. " However, in reality, it is rare that a call is received only from a telephone number registered as telephone directory information in advance, and an incoming call from a telephone number not registered as telephone directory information is regarded as a "malicious telephone". It is difficult for the user to recognize that it is not a number by displaying the incoming call information.

Therefore, in order to avoid calling a malicious telephone number, a user must take measures such as ignoring an incoming call from an unknown telephone number. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a communication device capable of determining whether or not an incoming telephone number is a malicious telephone number using one-ring. It is assumed that.

[0007]

In order to achieve the above object, a communication device according to the present invention detects the start and end of an incoming call when there is an incoming call, and measures the time from the start of the incoming call to the end of the incoming call (hereinafter referred to as the incoming end). , Called an incoming time), and the control means records the incoming time, the incoming telephone number, and the like as incoming information. According to such a configuration, it can be said that the arrival time of the telephone number recorded by one-ring is very short as compared with the normal arrival time, and therefore, by referring to the arrival time recorded as one of the arrival information, In addition, it is possible to determine a malicious telephone number recorded by one-way call from the incoming telephone numbers recorded as the incoming call information.

Further, if the recording of incoming information is controlled based on the incoming time and at least one predetermined time set in advance, for example, an incoming call whose incoming time is shorter than the predetermined time is recorded by one-ring. It is possible to recognize the received malicious telephone number and not record the incoming call information. In addition, for example, an incoming call with an incoming time shorter than a predetermined time and an incoming call with a predetermined time or more can be separately recorded. This prevents the user from calling a malicious telephone number due to an operation error or the like.

Further, in the case where the communication device includes a telephone directory information recording unit for registering a telephone number and information related to the telephone number as telephone directory information in advance, the telephone number registered in the telephone directory information is provided. With regard to an incoming call from, there is no need to determine whether the telephone number is malicious by notifying the telephone directory information together with the incoming call information. For this reason, it is preferable that the user set in advance whether or not to record the incoming time for an incoming call to the telephone number registered in the telephone directory information recording unit, and record this setting information as telephone directory information. As a result, unnecessary measurement and recording of the arrival time need not be performed. Further, when the communication device includes a display unit, it is possible to notify the user of the recorded incoming time together with other incoming information using the display unit.

FIG. 1 is a block diagram showing a configuration of an embodiment of a communication device according to the present invention. FIG. 2 is a flowchart showing a processing procedure of an operation when an incoming call occurs. FIG. 3 is a diagram showing an example of the incoming information display screen.
Hereinafter, this communication device will be described with reference to the drawings.
Description of the configuration related to transmission and reception of well-known communication devices is omitted.

As shown in FIG. 1, the communication device includes a recording unit 1 for recording various information relating to telephone numbers, and an incoming call judging means connected to a network via an antenna 2 for detecting the start and end of an incoming call. 3. Time measuring means 4 for receiving the notification of the start and end of the incoming call and measuring the incoming time, display means 5 such as a liquid crystal display (LCD) for displaying various information, processing such as screen switching of the display means 5, And control means 6 for controlling the recording process of the incoming information.

The recording unit 1 includes a reception information recording unit 11 and a telephone directory information recording unit 12. The reception information recording unit 11 has, for example, a reception telephone number 11a, a reception date and time 11b, and a time as reception information. The incoming time 11c and the like measured by the measuring means 4 are recorded. On the other hand, the telephone directory information recording unit 12
As telephone directory information, information relating to this telephone number such as a telephone number, for example, a name, and information for controlling the recording of incoming information for this telephone number (hereinafter referred to as recording control information) are stored in advance by the user. Registered by. In the present embodiment, the recording control information is setting information for determining whether or not to record an incoming time when an incoming call is received from the telephone number.

The incoming call judging means 3 notifies the control means 6 that the incoming call is started when a call is received from the caller and a call signal from the line network is received, and that the incoming call is terminated when the call signal is stopped. . The time measuring means 4 receives the notification of the start and end of the incoming call from the control means 6,
That is, the time from the start of the incoming call to the end of the incoming call is measured.

When there is an incoming call, the control means 6 controls the recording of incoming call information based on a predetermined time N set in advance. That is, if the incoming time 11c measured by the time measuring means 4 is equal to or longer than the predetermined time N, the control means 6 determines that the incoming call is a normal incoming call and determines the incoming telephone number 11a, the incoming call date and time 11b, and the time measuring means 4 Arrival time 1 measured by
1c is recorded in the incoming call information recording unit 11 as incoming call information.
On the other hand, if the incoming time 11c measured by the time measuring unit 4 is shorter than the predetermined time N, the control unit 6 determines that the incoming call is a one-time call and does not record the incoming information in the incoming information recording unit 11 for the incoming call. .

Next, an operation when an incoming call occurs in the communication device configured as described above will be described. First, the incoming call judging means 3 judges whether or not an incoming call has been received from the line network (step S1 in FIG. 2). If it is determined that the incoming call has started, the control means 6 determines whether or not to record the incoming time of the incoming call as incoming information (step S2). This determination is made by comparing whether or not the incoming telephone number matches the telephone number set to not record the incoming time in the recording control information among the telephone numbers registered in the telephone directory information recording unit 12. .

If the result of this determination is that the telephone number does not match the telephone number set to not record the incoming time, the control means 6
Notifies the time measurement unit 4 of the start of the arrival time measurement, and the time measurement unit 4 starts measuring the arrival time (step S3). Next, the incoming call determination means 3 determines whether or not the reception of the calling signal has been completed (step S).
4). Here, when it is determined that the incoming call has ended, the control unit 6 notifies the time measuring unit 4 of the end of the arrival time measurement.
The time measuring means 4 finishes measuring the incoming time, and notifies the controlling means 6 of the measured incoming time (here, n) (step S5).

The control means 6, which has been notified of the incoming time n, determines whether or not the incoming call is a one-time call, ie, determines whether the incoming time n measured by the time measuring means 4 is equal to the predetermined time N (for example, 1 second). A comparison is made (step S6). Here, if the incoming time n is equal to or longer than the predetermined time N, the control means 6
Determines that the incoming call is a normal incoming call, the incoming telephone number 11a,
The incoming call date and time 11b and the incoming time n measured by the time measuring means 4 are recorded as incoming information in the incoming information recording unit 11 (step S7). On the other hand, if the incoming time n is a predetermined time N
If the number is less than 1, the control unit 6 determines that the incoming call is a one-way call and does not record the incoming information in the incoming call information recording unit 11 for the incoming call, and ends the recording process.

If the result of the determination (step S2) as to whether or not the incoming time is recorded as incoming information matches the telephone number for which the incoming time is not recorded, the incoming time is measured. First, the incoming call determination means 3 determines whether or not the reception of the call signal has been completed (step S8). Here, when it is determined that the incoming call is terminated, the control means 6 records the incoming telephone number 11a and the incoming call date and time 11b as incoming information in the incoming information recording unit 11 (step S9).

The incoming information recorded in the incoming information recording unit 11 as described above is used when the user wants to confirm the incoming information.
For example, as shown in FIG. 3, the incoming telephone number 11 a, the incoming call date and time 11 b, and the incoming time (n) 11 c measured by the time measuring unit 4 are displayed on the display unit 5. When the incoming telephone number 11a is a telephone number registered in the telephone directory information recording unit 12,
The control means 6 reads out information related to the telephone number such as a name registered in the telephone directory information recording unit 12 corresponding to the incoming telephone number 11a, and displays the information together with the incoming telephone number 11a and the incoming call date and time 11b. To be displayed.

As described above, it is possible to determine a malicious telephone number by one-ring based on the incoming time 11c measured at the time of an incoming call and the predetermined time N set in advance. Can be prevented from being recorded. This prevents the user from calling a malicious telephone number due to an operation error or the like.

For a telephone number registered in the telephone directory information recording unit 12 by the user in advance, it is possible to set whether or not to record the arrival time when an incoming call is received from the telephone number. By notifying the telephone directory information together with the information, when there is no need to determine whether the telephone number is malicious, it is not necessary to measure and record the arrival time.

In this embodiment, the arrival time 11c
Is less than the predetermined time N, the incoming information is not recorded in the incoming information recording unit 11, but the present invention is not limited to this. For example, the arrival time 11c is a predetermined time N
If the number is less than the number, the incoming telephone number 11a, the incoming call date and time 11b, and the incoming time 11c may be used as incoming information and recorded separately in an area of the incoming information recording unit 11 that is different from the area for recording a normal incoming call. Good. In addition, the incoming telephone number 11a, the incoming call date and time 11b, and the incoming time 11c are recorded as incoming information in the incoming information recording unit 11 for all incoming calls without making a determination based on the incoming time 11c and the predetermined time N. No problem. Further, the present invention is not limited to the above-described embodiment, and various modifications can be made to the above-described embodiment without departing from the gist of the present invention.

[0023]

As described above, according to the communication device of the present invention, the time from the start of the incoming call to the end of the incoming call is recorded as the incoming call information, so that the malicious telephone number recorded by one-ring is recorded. Can be determined. This will prevent users from calling malicious phone numbers and replace them with malicious ones that had previously had to ignore incoming calls from unknown numbers. Very effective for. Further, by adding the information of the arrival time as the arrival information, it is possible to provide the user with a function of managing the arrival information in consideration of the arrival time.
