Description

  The present invention relates to a telephone connected to a public telephone line network, a cordless telephone, a telephone having a facsimile device function or a facsimile function, and outputting a countermeasure sound for suppressing a nuisance call such as a silent telephone. The present invention relates to a telephone having a function. In particular, the present invention, in a telephone having a function for outputting a countermeasure sound for annoying calls, continues to output the countermeasure sounds for a certain period of time after on-hook so that the countermeasure sounds output functions effectively for the caller of unwanted calls. In addition, the present invention relates to a telephone set that re-captures a line after a predetermined time when a user performs an off-hook operation for a call.

  Conventionally, in offices and homes, in addition to fixed telephones such as subscriber telephones connected to a public telephone line network, cordless telephones composed of a main unit and a sub unit connected by a wireless communication function have been widely used. In recent years, telephones to which a facsimile apparatus can be connected, telephones having a facsimile function in the base unit, and cordless telephones are also widespread. In this specification, the term “phone” includes a cordless telephone equipment and a telephone having a facsimile function.

  Recently, the damage caused by incoming unwanted calls such as silent calls and mischievous calls to telephones has increased, and there is a sound that causes discomfort to the other party's telephone (calling side telephone) when such unwanted calls are received. There has also been proposed a means for preventing a nuisance call from being made again from the same caller by outputting (repulse sound: hereinafter referred to as a countermeasure sound).

  For example, the following Patent Document 1 (Japanese Patent Laid-Open No. 8-149202) discloses a telephone corresponding to an annoying telephone (outputting a repulse sound) as a “cordless telephone”. This cordless phone is designed to increase the effect of the prank sound without taking time, and when it is judged that the receiving user is a nuisance call And an operation key for outputting a mischievous retreat sound, and when the user determines that it is a mischievous phone call, press the operation key to start outputting a repulse sound to the other party, and output a repulse sound while a busy sound is detected, When the other party hangs up the telephone and no longer hears the busy sound, the call is terminated and the apparatus returns to the standby state.

FIG. 6 is a flowchart showing an operation procedure when a nuisance call is received in the cordless telephone disclosed in Patent Document 1. As shown in FIG. 6, when the user receives a telephone call and determines that it is a mischievous telephone call during communication, the operation of S1 is performed by a key operation, and a mischievous retreat sound is sent to the line. Next, in S2, it is determined whether or not the cordless handset is on-charged. If it is on-charged, the process proceeds to step S3. Otherwise, the process proceeds to S4. In S3, the prank sound is output to the line and the loudspeaker, and the process proceeds to S5. In S4, the prank sound is output to the line and the cordless handset, and the process proceeds to S5. In S5, it is determined whether or not a busy sound is detected from the line. If a busy sound is detected, the process proceeds to S6, and if not, S2 is repeated. In S6, the telephone call is terminated and a standby state is entered.
JP-A-8-149202 (FIG. 1, FIG. 2, paragraph [0006])

In the cordless telephone disclosed in Patent Document 1, a repelling sound is output to the line based on a predetermined key operation. However, the technique disclosed in Patent Document 1 does not take into account the output operation of the repulse sound during the absence recording operation.
In the technique described in Patent Document 1, if a repelling sound is output in response to a key operation, the repelling sound is not sent to the other party unless the user performs a countermeasure sound output operation when the user is away. Alternatively, it is considered that there is no function for outputting the countermeasure sound during the absence recording operation.
For this reason, when there is an incoming call and the answering machine function is activated, it is not only possible to output a repelling sound and intimidate the other party, but also a message from the other party for the purpose of prank call is automatically recorded, Users who hear the message later will be uncomfortable.

  In view of such problems, the present invention outputs a countermeasure sound to the other party even when the answering machine function is activated, so that the repelling function can be effectively utilized.

The present invention is, after answer the call from unwanted call originating side, the telephone with nuisance calls measures sound output function for outputting a predetermined countermeasure sound to the line, off-hook handset is performed, the line by pressing the measure selection key The output of the predetermined countermeasure sound is invalidated and the period of time during which no sound is output from the calling side (silence period) is measured, and the output of the predetermined countermeasure sound is enabled when the predetermined period of time has elapsed. And the output of the countermeasure sound is invalidated until the silent period has passed a predetermined time or more .

The present invention makes it possible to avoid the output of countermeasure sound to an undesired line by the user pressing the countermeasure selection key by mistake during the time period of the silent period after the user off-hooks the handset. .

Hereinafter, specific examples of the present invention will be described in detail with reference to examples and drawings. FIG. 1 is an external view showing a configuration of a telephone having an annoying telephone countermeasure sound output function according to an embodiment of the present invention. FIG. 2 is a block diagram showing a configuration of a telephone having an annoying telephone countermeasure sound output function according to an embodiment of the present invention. In this embodiment, the description will be made by taking a cordless telephone as an example. However, in addition to a cordless telephone, the present invention can be applied to a normal fixed telephone, a telephone having a facsimile function, a telephone to which a facsimile apparatus can be connected, a cordless telephone, and the like. .
FIG. 1 is a diagram illustrating an appearance of a cordless telephone 10 according to a first embodiment of the present invention. In Example 1 below, when the cordless telephone 10 receives a nuisance call, the cordless telephone 10 is configured to output a countermeasure sound for suppression to the caller side, and the user then performs an off-hook operation for a call. In this case, a configuration for re-acquiring a line after a predetermined time has elapsed will be described.

  The cordless telephone 10 has a configuration in which a parent device 20 and a child device 30 are connected wirelessly so that calls can be received and transmitted from the child device 30 via the parent device 20. As shown in the block diagram of FIG. 2, the base unit 20 includes a telephone line control unit 21, an audio signal processing unit 22, a radio unit 23, a control unit 24, a microphone / speaker unit 25, an operation / display unit 26, a memory 27, An antenna 28 is provided. The control unit 24 is a control circuit composed of a microprocessor and includes a ROM and a RAM (not shown). The ROM stores a program for controlling the operation of each unit, and the control unit 24 can measure a call time, a silent period, a time from when an incoming call is automatically connected to a line, and a call charge. A program is also written. Information necessary for the operation of the control unit 24 is stored in the RAM.

  The telephone line control unit 21 controls incoming calls from the public line N and outgoing calls to the public line N, and performs incoming call detection, dial tone detection, and the like. The voice signal processing unit 22 processes the received voice signal and outputs it through the microphone / speaker unit 25 or processes the transmission voice input through the microphone / speaker unit 25 and converts it into a voice signal. Send it out. The wireless unit 23 communicates a transmission signal, an incoming signal, a transmitted voice signal, and a received voice signal with the slave unit 30 via the antenna 28.

  The operation / display unit 26 includes a display, function keys, numeric keys, and the like. The numeric keys are used for inputting a telephone number when making a call, and the function keys are used for selecting and setting various functions. It is done. That is, the function key is operated to display a desired function setting screen on the display to set various functions of the cordless telephone 10, and to set various service functions provided by the communication carrier on / off. be able to. For example, on / off settings such as a number display service, a call waiting display service, and a name display service can be set.

  Although not shown in the figure, the operation / display unit 26 is provided with a “measure selection key” for performing an operation for outputting a countermeasure sound such as a repelling sound when the user wants to judge the incoming call as a nuisance call. Yes. In addition, the control unit 24 is provided with a countermeasure selection detection unit 241 that detects when a countermeasure selection key is operated or when the base unit 20 determines that an incoming call is a nuisance call by determination described later. Further, the memory 27 is provided with a nuisance call countermeasure processing unit 271, a line connection continuation processing unit 272 for controlling connection continuation of the incoming line, a countermeasure sound (repelling sound) output control unit 273 for nuisance calls, and off-hook detection. A unit 274 and a line connection disconnection processing unit 275 are provided. These functions are substantially performed by the program control as in the operation procedure described later.

  As shown in the block diagram of FIG. 3, the slave unit 30 includes an audio signal processing unit 32, a radio unit 33, a control unit 34, a microphone / speaker unit 35, an operation / display unit 36, a memory 37, and an antenna 38. It is configured. The control unit 34 is a control circuit including a microprocessor, and includes a ROM and a RAM (not shown). The ROM stores a program for controlling the operation of each unit, and a program for the control unit 34 to communicate with the parent device 20 is also written therein. Information necessary for the operation of the control unit 34 is stored in the RAM.

  Whether or not the incoming call is a nuisance call can be determined by any of the following methods alone or in combination. The first is a case where the user determines that the incoming call is a nuisance call and operates the measure selection key. The second is a case where there is an incoming call that is repeated a predetermined number of times or more from the same source. In order to perform the second determination, the incoming call history shown in FIG.

  That is, as shown in FIG. 4, the incoming call history is configured to store the telephone number of the other party, the incoming time, the presence / absence of voice recording, and the number of incoming calls for each incoming call. The storage order advances the address of the storage unit in the order of arrival, and the order is from old arrival to new arrival. Therefore, if there is an incoming call from a telephone having the same telephone number at a continuous address, it can be determined that the incoming call is continuous by counting the number of incoming calls from that telephone number.

  According to another incoming call history storage method, it is configured to store the incoming time, voice recording presence / absence, and the number of incoming calls for each phone number of the incoming caller. For example, it is possible to count until the predetermined number of times is reached, and to clear the count value if the incoming time is not continuous. Accordingly, it is possible to determine that the incoming calls are continuous by referring to the number of incoming calls.

  Based on the flowchart shown in FIG. 5, the procedure of the countermeasure sound output control for the above nuisance call in the base unit 20 will be described. When there is an incoming call in the process of step S1, the telephone number on the calling side is acquired in the process of step S2. When the calling party telephone number is acquired, the countermeasure selection detection unit 241 determines whether it is the same as the calling party telephone number received previously with reference to the incoming call history of FIG. 4 in the process of step S3.

  If they are the same, it is determined whether the number of incoming calls (continuous) exceeds a predetermined number (for example, 3 times) in the process of step S4. If the number of incoming calls (continuous) does not exceed the predetermined number, it is determined that the incoming call is normal, and the process proceeds to step S9 to start counting of timer A (first timer). When the predetermined number of times is exceeded, the measure selection detecting unit 241 determines that the call is a nuisance call, and enters the processing after step S5 to perform the measure sound output processing.

  That is, in the process of step S5, the line connection disconnection processing unit 274 connects the line, the countermeasure sound output control unit 273 outputs a countermeasure sound in the process of step S6, and records the call in the process of step S7 (recording function). If is not turned on, this process is skipped). In step S8, it is detected whether or not the other party has disconnected the line. If the line has not been disconnected, the process returns to step S6 and the output of the countermeasure sound is continued. If a line disconnection is detected, the process returns to step S1 to return to an incoming call waiting state.

  After ringing the ring tone in the process of step S10, if the user goes off-hook in the process of step S11 for reception, the timer A count is cleared in the process of step S22, and the process of step S23 is performed. In step S24, the ringing tone is stopped, the line with the calling side is connected in the process of step S24, and the measurement of the silent period (silent period on the calling side) is started in the process of step S25.

  In step S26, if the silent period has not elapsed for 10 seconds, the line connection is maintained in step S27, and if the line is disconnected in the subsequent step S28 (for example, the calling side or called side performs an on-hook operation). If not, the process returns to step S26.

In step S29, enable the measure selecting key (Note that to step S28 and to disable the measure selecting key, have enabled measure selecting key starting to silent period has elapsed 10 seconds).

If it is determined in step S30 that the line is disconnected, the process returns to step S1, and if not, the process proceeds to step S31. If the countermeasure selection key is pressed in step S31, a repulse sound is output to the line in step S32, and if not, the process returns to step S30.

  In step S33, the telephone number of the other party currently connected is stored in the memory and the number of incoming calls is counted up. After the line is closed, the process returns to step S1.

  Returning to step S11, if it is not off-hook in step S11, counting of a predetermined time is started in step S12. The predetermined time here is the time from the start of the incoming call until the line is automatically connected and the response message is sent to the line.

  If the predetermined interval is counted in step S12, ringing of the ringtone is stopped in step S13, the line is connected in step S14, and recording of the calling side voice input from the line is started in step S15. Subsequently, in step S16, a message (for example, the telephone cannot be answered) is output to the line, and the process proceeds to step S17.

  In step S17, measurement of a silent period (silent period on the calling side) is started. In this embodiment, the silent period measurement start timing is after the response message is sent to the line. However, the silence period may be started together with the line connection, or the measurement start is started when the response message is sent. May be.

  In step S18, if it is determined that the silence period started in step S16 is a predetermined time (for example, 10 seconds), the process proceeds to step S19, and a repulse sound is output to the line. On the other hand, if the silent period is not a predetermined time, the process proceeds to step S21. If it is determined in step S21 that there is a repulse sound output operation, the process proceeds to step S19, and if not, the process proceeds to step S20.

  If it is determined in step S20 that the line has been disconnected, the process returns to step S1.

  As described above, the device according to the present embodiment automatically applies the countermeasure sound to the line if the predetermined time elapses after the incoming call and the line is automatically connected and the silent recording state continues for a predetermined period of time after entering the absence recording state. Is output. For this reason, it is possible to output countermeasure sound even when the user is away. In addition, when the user performs an operation to output a countermeasure sound (attack sound) in the absence recording state, the countermeasure sound is output to the line, so even if the user is near the telephone in the absence recording state, when the user likes The countermeasure sound can be output.

  In this embodiment, the silence period is counted as 10 seconds. However, the silence period is not limited to 10 seconds, and the silence period may be set by the user.

  Further, when the countermeasure sound is transmitted to the line, the recording of the message message input from the calling side may be prohibited, or the recorded message message may be deleted. By adopting such a configuration, the user can avoid feeling uncomfortable by listening to a message from the calling party for the purpose of mischief later.
