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 continues to output countermeasure sound for a certain period of time after off-hook so that the countermeasure sound output functions effectively for the caller of the nuisance call in the telephone having the function of outputting the countermeasure sound of the nuisance call. It relates to telephones.

  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 mischief calls has also increased, and this makes the other party's phone (calling phone) uncomfortable. There has also been proposed a means for preventing a nuisance call from being made again from the same caller by outputting a sound (repulse 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 call, the operation key is pressed to start outputting a repelling sound to the other party, and a repulse sound is output 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. 7 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. 7, 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 the above-mentioned Patent Document 1, the transmission of the countermeasure sound is always continued even if it is on-hook while the countermeasure sound is being output. With such a configuration, the line remains connected unless the calling party who has made a call for mischief calls goes on-hook. For this reason, it is impossible to make a call when the user wants to immediately terminate the call with the other party for the purpose of the mischievous call and immediately call the other party.

In order to solve the above-mentioned problems, the present invention provides a telephone having an annoying phone countermeasure sound output function for outputting a predetermined countermeasure sound to the spam caller side when it is determined that the incoming call is a nuisance call. The telephone includes a countermeasure selection detection unit, a nuisance call countermeasure processing unit including a line connection continuation processing unit, a countermeasure sound output control unit, a line connection disconnection processing unit, and a countermeasure selection key . When the countermeasure selection detection unit detects an operation of the countermeasure selection key, it determines that the incoming call is a nuisance call, and then the countermeasure sound output control unit outputs a countermeasure sound to the line, and the countermeasure sound is being output. When the own telephone is on-hooked, the line connection continuation processing unit continues the line connection until a predetermined time elapses from the on-hook operation, and during the line connection, the countermeasure sound output control unit Output Characterized in that it continue.

The invention according to claim 2 of the present application is the telephone according to claim 1,
When the telephone is off-hooked and the countermeasure selection detection unit detects that a nuisance call countermeasure key provided on the operation / display unit is operated, it is determined that the incoming call is a nuisance call.

The invention according to claim 3 of the present application is the telephone according to claim 1 or 2,
The telephone is provided with means for storing at least the telephone number of the calling side and the incoming time as an incoming history, and when the number of consecutive incoming calls from the same calling number exceeds a predetermined number of times, the countermeasure selection detection unit receives the incoming call It is characterized in that the telephone is determined to be a nuisance call.

In the invention according to claim 1, during the call, the measure selection detection unit determines that the incoming call is a nuisance call when detecting the operation of the measure selection key , and then the measure sound output control unit measures the line. If the telephone is on-hooked while the countermeasure sound is being output , the line connection continuation processing unit continues the line connection until a predetermined time has elapsed from the on-hook operation, and between the line connections. The countermeasure sound output control unit continues the countermeasure sound output.

  Therefore, even if the user makes an on-hook operation when receiving a nuisance call, the line connection is continued until a predetermined time has elapsed since the on-hook operation, and the countermeasure sound is output during that time, so the other party's telephone disconnects. Since the predetermined set time countermeasure sound output is continued until the nuisance call suppression effect by the countermeasure sound output can be improved. Further, since the countermeasure sound is output only for a predetermined time, the user can make a call to another party immediately after the predetermined time elapses.

  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.

The ROM stores a program for controlling the operation of each unit, and a program for allowing the control unit 24 to measure a call time and to calculate a call charge 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 to input a telephone number when making a call, and the function keys are used to select and set 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 (repulse sound) output control unit 273 for the nuisance call, a line connection A cutting processing unit 274 is 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.

  Next, the procedure of the countermeasure sound output control for the nuisance call in the base unit 20 will be described based on the flowcharts shown in FIGS. When there is an incoming call in the process of step S11, the telephone number on the calling side is acquired in the process of step S12. 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 that has been previously received with reference to the incoming call history of FIG. 4 in the process of step S13.

  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 S14. If the number of incoming calls (continuous) does not exceed the predetermined number of times, it is determined that the incoming call is a normal incoming call, the process proceeds to step S19, the timer A (first timer) is started, and a ringing tone is generated in step 20. 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 S15 to perform the measure sound output processing.

  That is, in the process of step S15, 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 S16, and records the call in the process of step S17 (recording function). If is not turned on, this process is skipped). In step S18, 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 S16 to continue outputting the countermeasure sound. If a line disconnection is detected, the process returns to step S11 to return to an incoming call waiting state.

  On the other hand, after ringing the ring tone in the process of step S20, if the user off-hooks the handset of the main unit 20 in the process of step S21 for reception, the count of timer A is cleared in the process of step S28, and step S29. In step S31, the ringing tone is stopped. In step S30, the line with the calling side is connected. In step S31, it is monitored whether the other side is disconnected. When it is detected that the other party has disconnected the line, the process returns to the process of step S11 to return to the incoming call waiting state.

  If the other party is not disconnected, the measure selection detection unit 241 performs an operation for outputting a countermeasure sound such as a repulse sound when the user wants to determine that the incoming call is a nuisance call in the process of step S32. It is detected whether or not a countermeasure selection has been performed by operating the “measure selection key” on the display unit 26. If the measure selection key has not been operated, the process returns to step S31 to continue monitoring the other party's line disconnection. During this time, it is needless to say that the parent device 20 performs a call operation with the other party.

  When the measure selection key is operated, the measure selection detection unit 241 determines that the call is a nuisance call, and enters the processing after step S33 and performs a measure sound output process. That is, the countermeasure sound output control unit 273 outputs a countermeasure sound in the process of step S33, and records, records, and counts the number of incoming calls in the process of step S34. In step S35, it is determined whether or not the handset is on-hook (call end). If it is not on-hook, it returns to the process of step S33 and the output of the countermeasure sound is continued.

  If an on-hook is detected in the determination process of step S35, the process proceeds to the process of step S40 in the flowchart of FIG. 6, and the process of the present invention is performed to continue outputting the countermeasure sound for a predetermined time. That is, even if the user puts the handset (on-hook) and terminates the call with the other party, the line is not disconnected and the output of the countermeasure sound is continued, thereby improving the effect of suppressing unwanted calls.

Therefore, it is determined whether or not line disconnection is set in the process of step S40. The presence / absence of the line disconnection setting is set in advance by the user's operation. When the on-hook operation is performed in step S35 in FIG. 5, the line is disconnected or a repulse sound is transmitted while the line is connected. This can be set by the user.
If the time until line disconnection is not set in step S40, the process proceeds to step S44, and the line connection disconnection processing unit 274 immediately disconnects the line. On the other hand, if the time until line disconnection is set, the line connection continuation processing unit 272 performs the process of continuing the line connection in the process of step S41, and the control unit 24 counts a predetermined time (for example, 1 minute). To start. In the process of step S42, the countermeasure sound output control unit 273 continues to output the countermeasure sound.

  In the process of step S43, it is determined whether or not the line disconnection set time (predetermined line connection continuation time) started in the process of step S41 has elapsed or the caller has performed the process of disconnecting the line. If the set time for line disconnection has not elapsed, the process returns to step S42 to continue outputting the countermeasure sound, and when the set time for line disconnection has elapsed, the line is disconnected in the process of step S44, and step S11 (FIG. 5). Return to the process of (see) and return to the waiting state for incoming calls.

  On the other hand, after the ringing tone is sounded in the process of step S20, if the handset of the base unit 20 is not off-hooked in the process of step S21, the process of recording the answering machine starts when the timer A counts a predetermined time. . That is, in the process of step S22, the counting time of the timer A is determined. If the predetermined time has not been counted, the process returns to the process of step S20 and the ringing tone continues.

  When the count of the timer A has passed a predetermined time, ringing is stopped in the process of step S23, the line with the other party is connected in the process of step S24, and recording is started. At the start of recording, an answering machine recording message is transmitted in the process of step S26. If the call (recording) is terminated in the process of step S27 and the other party disconnects the line, the process is terminated, and the process returns to the process of step S11 to return to the incoming call waiting state.

  In the above-described embodiment, the configuration in which the presence / absence of the setting for continuing the countermeasure sound output until the predetermined period elapses in the processing of step S36 after detecting the on-hook has been described, but this setting is arbitrarily set by the user. This setting may be made in advance before a call, or may be set from the operation / display unit 26 during the process from step S20 to step S25 (on-hook). It can also be configured to.

  In this way, the user can select whether or not to set arbitrarily, and by enabling the setting during communication, the other party is intimidated and suppressed by countermeasure sound output, and if it is determined that it is a nuisance call, the police etc. When the user wants to make a phone call, the user can set on-hook after performing a setting operation, and the effect of suppressing annoying calls can be further enhanced.

  As described above in detail, according to the present invention, when a side receiving a nuisance call or a mischievous phone outputs a repulse sound, the countermeasure sound (repulse sound) continues to be output for a certain time after the off-hook. Therefore, the countermeasure sound output can be effectively made to function for annoying callers.
