Description

The present invention relates to a telephone and a method of controlling the telephone, and more particularly to a telephone having a nuisance telephone number prevention function.

Conventionally, there is a telephone that performs a predetermined function such as starting a mail application according to the frequency of incoming calls from the same telephone number by referring to the incoming call history (Patent Document 1). In addition, there are telephones that refer to the incoming call history and determine an incoming call that is likely to be a nuisance call according to the frequency of incoming calls from the same telephone number within a predetermined period. The telephone of the latter example extracts the incoming call history related to the incoming call within a predetermined period based on the incoming call date and time included in the incoming call history. Then, the frequency of incoming calls from the same telephone number within a predetermined period is calculated with reference to the extracted incoming call history. The incoming date and time included in the incoming call history is usually calculated based on the reference date and time that the user enters on the phone as the current date and time.

WO2009 / 014074 (published on January 29, 2009)

When the power of the telephone is temporarily turned off due to a power failure or the like, the reference date and time information recorded on the telephone is initialized. After that, the telephone calculates the incoming date and time based on the default reference date and time during the period from the restart of the telephone to the re-entry of the reference date and time information into the telephone. However, the default reference date and time usually does not match the current date and time. Therefore, the incoming date and time calculated based on the default reference date and time does not match the actual incoming date and time. As a result, the telephone cannot accurately calculate the incoming call frequency within a predetermined period based on the incoming call history.

A solution to the above problem is to install a battery in the telephone so that the reference date and time information input to the telephone is not lost even if the power of the telephone is temporarily turned off. .. Another possible solution is to provide a radio clock or the like on the telephone so that the telephone can acquire reference date and time information from the outside. However, both of these solutions are undesirable because they add cost to the phone.

One aspect of the present invention is to realize a telephone capable of grasping the frequency of incoming calls within a predetermined period based on the incoming call history even when the reference date and time information input to the telephone is temporarily lost. And.

In order to solve the above problems, the telephone according to one aspect of the present invention is a telephone that executes a predetermined function according to the frequency of incoming calls, and is modified by the default reference date and time or the input to the telephone.

In the case of an incoming call history calculated based on the modified reference date and time, the incoming call frequency calculation unit specifies that the incoming call history is within the predetermined period based on the incoming call date and time. However, in the case of an incoming call history in which the incoming call date and time is calculated based on the default reference date and time, the two incoming call dates and times are calculated based on the modified reference date and time based on the order in which the incoming calls were received. between the incoming call history, incoming history the incoming date is calculated based on a reference date and time of the initial setting, it is specified as the incoming call history in the above-mentioned predetermined time period.

In order to solve the above problems, the telephone control method according to one aspect of the present invention is a telephone control method that executes a predetermined function according to the frequency of incoming calls, and is the default reference date and time or the telephone. The incoming date and time is calculated based on the reference date and time corrected by inputting to, and if the incoming call history is calculated based on the corrected reference date and time, the incoming call history is within a predetermined period based on the incoming date and time. In the case of an incoming call history calculated based on the above-mentioned default reference date and time, the above-mentioned incoming date and time is set to the above-corrected reference date and time based on the order in which the incoming calls were received. between two received call history, calculated on the basis, the incoming call history in which the incoming date is calculated based on a reference date and time of the initial setting, by identifying that the incoming call history in the predetermined time period, within a predetermined time period Calculate the incoming frequency of.

According to one aspect of the present invention, even when the reference date and time information input to the telephone is temporarily lost, the frequency of incoming calls within a predetermined period can be grasped based on the incoming call history.

(Configuration of telephone 1)
FIG. 1 is a block diagram showing a configuration of a telephone 1 according to the first embodiment. As shown in FIG. 1, the telephone 1 includes a control unit 10, an output unit 20, and a storage unit 30.

The control unit 10 integrally controls the operation of each unit of the telephone 1. When receiving a call from an unregistered number (phone number not registered in the telephone 1), the control unit 10 determines whether or not the incoming call may be a nuisance call based on the incoming call history recorded in the storage unit 30. To do. When it is determined that the incoming call may be a nuisance call, the control unit 10 outputs a warning message to the user from the output unit 20. As shown in FIG. 1, the control unit 10 includes a reference date / time setting unit 11, a setting initialization unit 12, an incoming call date / time calculation unit 13, a arrival history generation unit 14, an incoming call date / time correct / incorrect recording unit 15, an incoming call frequency calculation unit 16, and The warning message generation unit 17 is included. Each part of the control unit 10 will be described later.

The output unit 20 includes a display, a speaker, and earpieces. The storage unit 30 stores an incoming call history, that is, information regarding an incoming call to the telephone 1. The incoming call history includes at least each information of the incoming date and time and the incoming number. The storage unit 30 also stores reference date / time information and incoming date / time correct / incorrect information. The reference date / time information is information on the reference date / time input to the telephone 1 or the initially set reference date / time. The incoming date / time correct / incorrect information is information (flag) indicating whether or not the incoming date / time included in the incoming call history is correct. When the incoming date and time included in the incoming call history is correct, the incoming date and time correct / incorrect information is flag = 1. If the incoming date and time included in the incoming call history is incorrect, the incoming date and time correct / incorrect information is flag = 0.

(1. Reference date / time setting unit 11)
When the telephone 1 is activated, the reference date / time setting unit 11 records the default reference date / time information in the storage unit 30. Further, the reference date / time setting unit 11 records the reference date / time recorded in the storage unit 30 when the user inputs the current date / time to the telephone 1 or when the reference date / time information is received from a slave unit separate from the telephone 1. Correct the date and time information. In these cases, the reference date / time setting unit 11 notifies the incoming date / time correct / incorrect recording unit 15 that the reference date / time information has been corrected.

(2. Setting initialization unit 12)
When the power of the telephone 1 is turned on, the setting initialization unit 12 initializes the reference date / time information recorded in the storage unit 30. That is, the setting initialization unit 12 overwrites the reference date / time information recorded in the storage unit 30 with the reference date / time information of the initial setting (in this embodiment, 00:00 on January 1, 2016). In this case, the setting initialization unit 12 notifies the incoming date / time correct / incorrect recording unit 15 that the reference date / time has been initialized.

(3. Incoming call date / time calculation unit 13)
The incoming call date / time calculation unit 13 calculates the incoming call date / time, that is, the current date / time at the time of receiving the incoming call. Specifically, the incoming call date / time calculation unit 13 acquires information on the reference date / time from the RTC (Real Time Clock) provided in the telephone 1. Then, the reference date and time acquired from the RTC is set as the incoming date and time. Here, the RTC updates the reference date and time stored in the storage unit 30 as the reference date and time information at regular time intervals from the time when the telephone 1 is activated. Therefore, the incoming date / time calculation unit 13 can acquire the updated reference date / time information from the RTC.

(4. History generation unit 14)
When an incoming call arrives, the arrival history generation unit 14 acquires the incoming call number information and also receives the incoming call date / time information calculated by the incoming call date / time calculation unit 13. Then, the arrival history generation unit 14 associates the incoming date and time information with the incoming number information and records it in the storage unit 30 as an incoming call history. In addition, the arrival history generation unit 14 notifies the incoming call date / time correct / incorrect recording unit 15 that the incoming call history has been generated. The incoming call history may also include information such as the name of the caller and the type of telephone number (fixed telephone, mobile phone, toll-free number, public telephone, etc.).

A method in which the arrival history generation unit 14 generates an incoming call history will be described with reference to FIG. 2A. FIG. 2A shows a case where there are n incoming calls. As shown in FIG. 2A, the arrival history generation unit 14 generates an incoming call history related to the incoming call each time there is an incoming call, and records the generated incoming call history in the storage unit 30 (queuing). The arrival history generation unit 14 adds an incoming call number to each incoming call history. Specifically, the arrival history generation unit 14 describes the incoming call No. in the latest incoming call history. 1 is added. When recording the latest incoming call history in the storage unit 30, the arrival history generation unit 14 increases the incoming call number of the old incoming call history by one. For example, as shown in (a) of FIG. 2, when there is an incoming call 2 following the incoming call 1, the arrival history generation unit 14 receives the incoming arrival history / arrival history of the incoming call 1 (the arrival history of (a) of FIG. 2). Change the incoming call number in 1) from 1 to 2. Further, in the incoming call history related to the incoming call 2 (arrival history 2 in FIG. 2A), the incoming call No. 1 is added. When the number of incoming call histories recorded in the storage unit 30 exceeds n, the incoming call history generation unit 14 has the oldest incoming call history, that is, the incoming call No. The incoming call history of n (arrival history 1 in FIG. 2A) is deleted from the storage unit 30.

(5. Incoming date / time correct / incorrect recording unit 15)
When the incoming call history generation unit 14 notifies that the incoming call history is generated, the incoming call date / time recording unit 15 sets the incoming call date / time included in the incoming call history generated by the incoming call history generation unit 14 by the method described below. Determine if it is correct. The incoming date / time correct / incorrect recording unit 15 records the determination result (flag) in the storage unit 30 as the incoming date / time correct / incorrect information.

When the reference date / time setting unit 11 has set the reference date / time information at the time of incoming call, that is, when the reference date / time has already been corrected by the user's input or the like, the incoming call date / time correct / incorrect recording unit 15 includes the incoming call history. Judge that the date and time are correct. On the other hand, when the incoming call is received, if the reference date / time information of the storage unit 30 is the initial setting, that is, the reference date / time information has not been corrected even once, or the setting initialization unit 12 has initialized the reference date / time information. In this case, the incoming date / time correct / incorrect recording unit 15 determines that the incoming date / time included in the incoming call history is incorrect.

A method of generating the incoming date / time correct / incorrect information by the incoming date / time correct / incorrect recording unit 15 will be described with reference to FIG. 2 (b). FIG. 2B shows a case where there are n incoming calls. As shown in FIG. 2B, each time there is an incoming call, the incoming call date / time correct / incorrect recording unit 15 determines whether or not the incoming call date / time included in the incoming call history generated by the arrival history generation unit 14 for the incoming call is correct. Judgment is made by the method described above. Then, the incoming date / time correct / incorrect recording unit 15 records the incoming date / time correct / incorrect information indicating the result of the determination in the storage unit 30 in association with the incoming call history. Specifically, when the incoming call date / time included in the incoming call history is correct, the incoming call date / time correct / incorrect recording unit 15 records the flag = 1 in the storage unit 30 as the incoming date / time correct / incorrect information. On the other hand, when the incoming call date / time included in the incoming call history is incorrect, the incoming call date / time correct / incorrect recording unit 15 records flag = 0 in the storage unit 30 as the incoming date / time correct / incorrect information.
