JP6040129B2 - High-functional telephone - Google Patents

Description

  The present invention relates to a high-function telephone having a nuisance call countermeasure and a new fax function.

  As shown in Patent Document 1, a technology for rejecting unwanted calls is provided in the technology for preventing unsolicited incoming calls to ordinary households due to wire fraud and unscrupulous sales. A method of managing the nuisance telephone number by sending it to the management server and making it a database in the management server, and the characteristic that many nuisance calls as described in Patent Document 2 start talking unilaterally with an automatic voice announcement on the calling side Although a technique is disclosed in which connection control is performed so as not to permit an incoming call when it is detected, a nuisance call is not necessarily an automatic voice announcement and is not a fundamental countermeasure.

    In recent years, many telephones are provided with a fax function. For this reason, a scanner or a printer is added to the telephone, and the telephone is thus increased in size.

JP2012-109842 JP 2010-124509 A

  An object of the present invention is to provide a high-function telephone that does not require an operation button for rejecting a nuisance call on the telephone and that can be determined as a nuisance call in any conversation form. In addition, it is possible to reduce the size of the telephone by using a scanner with a fax function and a printer function (reading and printing functions) that is owned by a personal computer widely used in ordinary households. .

    In the present invention, the object of the invention is achieved as follows.

1. Record all incoming phone calls automatically, observe the conversation flow and conversation pattern from the beginning to the end of the phone call, recognize unique words that tend to be annoying calls, and judge them as annoying calls However, when the determination is unknown, the conversation content is automatically transmitted to the call center, and further examination is performed at the call center to determine whether the call is a nuisance call. If it is determined that the call is a nuisance call, the telephone is set so that calls from the nuisance call number will not be received thereafter.
2. The phone has a WiFi wireless function, reads the fax transmission document from the scanner using WiFi, sends the fax using the fax communication function of the phone, and transfers the received fax to the printer using the WiFi wireless function for printing. To do.

    As described above, according to the present invention, it is possible to automatically prevent a telephone from receiving a nuisance call without requiring a special operation for countermeasures against the nuisance call. In addition, the telephone can be reduced in size, weight, and power consumption.

1 is an overall configuration diagram of the present invention. It is a block diagram of the telephone of this invention. It is a figure which shows the internal logical structure of a data memory. It is a block diagram of a call center. (A), (b) is a figure which shows the format of the communication signal between a telephone and a call center. (A), (b) is a figure which shows the example of a different pattern of telephone conversation. (A), (b) is a figure which shows the signal format from which the communication signal between a call center and a telephone at the time of the software update of a telephone differs.

  In FIG. 1, a telephone 1-1, a personal computer 1-2, and a printer / scanner 1-3 are placed in a home, and these are connected by WiFi wireless. A pattern of connection to a call center 1-5 through a public network 1-4 such as a wireless communication network is shown. The call center 1-5 can also be connected to the Internet from the personal computer 1-2 in the home via the Internet network 1-6. The call center operation form may be a telephone manufacturer's call center (customer consultation desk), the Consumer Affairs Office's complaint reception desk, or the National Police Agency's consultation desk.

  FIG. 2 shows the internal configuration of the telephone.

  The NCU 2-1 is a network control circuit that controls connection with a public network such as a subscriber telephone line, and the modem 2-2 is a facsimile transmission / reception, a dial signal for automatic telephone call generation, and a caller ID notification signal (number display). ) For reception. The communication control unit 2-3 controls the fax communication protocol, transmits a voice signal that seems to be a nuisance call to the call center 1-5 together with the telephone number that originated the nuisance call, or sends it as a nuisance telephone number from the call center 1-5. Controls the reception of the information that is sent.

  The handset 2-5 is generally equipped with a microphone and speaker for telephone conversation, which is also called a handset. The content of the telephone conversation is analyzed by the conversation content analysis unit 2-7 by the method described later. It is then determined whether the call is a nuisance call. The data memory 2-4 is a memory for recording all the contents of the telephone conversation, the image conversion unit 2-8 is for converting the format of the fax signal and the scanner printer signal, and the WiFi circuit 2-11 is a personal computer 1-2, This is a circuit for transferring information to and from the printer / scanner 1-3 via WiFI wireless. When the conversation content analysis unit 2-7 determines that this conversation is a nuisance call, the telephone directory management unit 2-10 manages the telephone number of the caller of the telephone. In addition, this telephone number from the call center 1-5 is managed together with a telephone number reported as a nuisance call. The phone book management unit 2-10 manages a history of phone numbers determined to be nuisance calls (including that it is determined that the determination is unknown). This telephone number is used for updating such as setting to reject incoming calls from a certain telephone directory list. The history data in the telephone directory management unit 2-10 can be transferred to the printer / scanner 1-3 and printed as necessary. The incoming / outgoing call control unit 2-6 identifies the caller telephone number transmitted from the public network 1-4 when there is an incoming call, and compares it with the telephone directory 2-9. When the incoming call is rejected or the conversation content analysis circuit 2-7 is determined to be a nuisance call, it automatically calls the call center 1-5 and the nuisance call generated by the communication control unit 2-3. Send the phone number conversation details.

  FIG. 3 shows a simplified logical memory structure of the data memory, which comprises a conversation history section for recording all conversations once, an answering machine recording section, and a fax data section. Although not described here, the answering machine is recorded by many answering machines, and the deletion is performed by the operation of the person who heard the answering machine.

Next, a series of flows when a call is received will be described.
When there is an incoming call, the telephone rings as usual and talks with the handset 2-5.
At this time, conversation contents are automatically recorded in the data memory 2-4. The conversation content analysis circuit 2-7 analyzes the conversation pattern, and if it is determined that the call is not a nuisance call after the conversation is finished, the call is finished as if there was nothing, and the recorded conversation content is automatically deleted immediately. Is done. If you don't want to delete it immediately, but want to save it for a while, you can set a storage period such as 3 days from the operation display unit 2-13 in the initial setting of the telephone 1-1. Good.

  When the conversation content analysis unit 2-7 determines that this conversation is a nuisance call after the conversation ends, the telephone number of the callee at that time is managed as a nuisance telephone number by the telephone directory management unit 2-10. Then, by updating the telephone directory 2-9, incoming calls from that telephone number are subsequently rejected. When the analysis result in the conversation content analysis unit 2-7 cannot determine whether it is a nuisance call, the conversation content is analyzed again while listening to the conversation content again from the data memory 2-4 in which the conversation content is recorded. In this case, since it is not necessary to analyze in real time, the difficult-to-understand location can be challenged any number of times. If the determination is still unclear, the telephone number and date / time information of the call destination and the recorded conversation contents are automatically called to the telephone number of the call center 1-5 set in advance. At this time, the incoming / outgoing call control unit 2-6 controls outgoing calls to the call center 1-5. As shown in FIG. 5A, the format of a signal transmitted to the call center 1-5 includes a control signal part, a telephone number part, a date / time information part, a serial number, and a conversation content part. The transmission of the serial number is not necessary for determining whether the call is a nuisance call, but is information necessary for software download to be described later. When the transmission to the call center is completed, the conversation content does not need to be saved, but it is better to save it for about a day just in case. The storage period is automatically deleted with a default of 24 hours. If it is desired to store for a longer time, the storage period may be set in the initial setting described above.

  The call center 1-5 examines the content of the received conversation and, when it can be determined that the call is a nuisance call, automatically notifies the telephone to that effect. The signal is in the signal format of FIG. 5 (b), and the conversation content need not be included.

  The operation of the conversation content analysis unit 2-7 will be described.

As shown in Fig. 6 (a), when a general telephone conversation is received, the caller starts with a (which is XX) and the caller confirms each other with b (I am YY). After that, after greetings from c (Long time, how are you?)
In the question of d (By the way, ZZ, what's the best day?), e (except for VV, it ’s okay), f (then, what month and what time of day), g (OK) We are waiting for you), h (I'm sorry for your busy time, thank you for the day), j (Now, goodbye), the conversation proceeds, and greetings are exchanged at the beginning and end of the conversation The contents include catch balls d and e, and the words (thank you) from the caller are often entered along the way.

  However, in the nuisance call pattern, as shown in Fig. 6 (b), after the caller answers with a, one-way long explanation k (XX, but I will guide you about TT. The product is epoch-making ... and so on. During this time, if the caller says something, m (which is fine) will be ignored and will be followed by a one-sided explanation p. After a long explanation, when the caller asks a question q, there is a longer explanation r, dislikes, and s (hangs up, sorry) and the call is hung up. Depending on the person's emotions, he often hangs up without a single word, and there is no normal first and last greeting conversation, and the conversation continues with the caller's long conversation. When the conversation ends, it is presumed to be a nuisance call.

  The conversation content analysis unit 2-7 measures the first and last greeting conversations, the conversation sequence during conversation, whether or not there is a catch ball of each other, the conversation time of the calling party, and the conversation time of the called party. The words "thank you" of the callee during the conversation, and words exchanged at the end of the conversation, words such as "goodbye", "thank you in advance", "see you again", are monitored while recognizing voice. To determine if it is a nuisance call. As a conversation pattern, there is a catch ball of conversation. When the caller's word “thank you” in conversation, the number of words “thank you” is recognized at the end of the conversation, “goodbye”, “good-bye”, “see you”, It is determined that the call is not a nuisance call. As a conversation pattern, if the conversation time on the caller side is abnormally long, such as three quarters or more compared to the callee, and there is no greeting pattern at the end of the conversation, it is determined as a nuisance call.

  In addition, there are words in the conversation of the caller such as “BB 10,000 yen is needed now”, “Please transfer to GG bank”, “I will ask you to receive money” in the caller's conversation, The caller ’s words should be “Yes?”, “I understand”, “Yes,” and “What time is it?” If you can recognize that type of word, judge. When it is determined that it is a nuisance call, the operation display section 2-13 (not shown in detail, but consisting of operation buttons such as LCD, scroll keys, and decision keys, and a speaker) “OK?” Appears on the LCD, and unless the called operator operates “NO” within a certain period of time (for example, 60 seconds), it is registered in the telephone book 2-9 as a nuisance telephone number. Incoming calls are rejected. When it is determined that the above-mentioned fraudulent fraud is also a nuisance call, a message to that effect is displayed on the operation display section 2-13, and the voice is announced as "Transfer fraud. Call attention. When it is unclear whether or not it is a nuisance call, it is analyzed again by the method described above. If it is still unclear, the call center 1-5 is contacted for a determination. As a method of contacting the call center, there is a method using the Internet in addition to the method using the telephone network. An IP circuit 2-12 shown in FIG. 2 is a circuit that generates and restores the signal format shown in FIG. 5 as an Internet protocol signal, and its output / input is sent from the WiFi circuit 2-11 to the personal computer 1-2 in the home. The personal computer 1-2 automatically transmits a signal from the telephone 1-1 to the mail address of the call center 1-5. In addition, an incoming mail from the call center 1-5 (determination result as to whether or not the transmitted information is a nuisance call) is received, and the telephone set 1-1 is contacted via the WiFi circuit 2-11. As a means of contacting the call center 1-5, if there is an internet environment in the home, it is better to use the internet network in terms of the cost of telephone billing than to contact the call center by automatic call by telephone. If there is no internet environment, select the telephone network.

  As shown in FIG. 4, the call center 1-5 receives a signal from the public network 1-4 or the Internet network 1-6 through the communication circuit 4-3. Analysis is performed at 1. The voice recognition unit 4-1 of the call center has a higher recognition function than the voice recognition function (recognizing the typical conversation pattern at the end of the telephone conversation described above) installed in the telephone. For example, it is possible to recognize many words such as a conversation that the callee makes in the middle, “I don't like it”, “I ’m annoying”, “Don't make the same call”, “I refuse”. If it is difficult to determine that this conversation is a nuisance call even if the speech recognition unit 4-1 recognizes such various words, the person directly listens to the conversation content in the human analysis unit 4-2. Determine if it is a nuisance call. When it is determined that the call is a nuisance call, the determination result transmission unit 4-4 notifies that the number is a nuisance call together with the call destination telephone number of the nuisance call in the signal format of FIG. 5b. All of the nuisance call determination work processed in the call center 1-5 is recorded and managed in the history management unit 4-5.

  In addition, this phone number is determined to be a nuisance call in the judgment of a nuisance call alone or in the call center, and subsequent calls are automatically set to be rejected, but some people think that it is not a nuisance call, There are times when you want to accept incoming calls even if you are making a nuisance call. Therefore, it is possible to operate the telephone directory 2-9 on the operation display unit 2-13 to cancel the setting as a nuisance call for the selected telephone number.

  In the above description, the voice recognition function of the call center 1-5 is implemented with advanced functions such as possessing more keywords (word dictionary) by the voice recognition function possessed by the telephone. It is also possible to install a voice recognition function on the telephone, depending on the computing power (computer power and memory capacity) of the telephone. If you are concerned about the telephone charge to the call center, it is desirable to install an advanced voice recognition function on the phone. If you are not concerned about the telephone charge, such as when connected to the Internet, install a mild voice recognition function, or The telephone may not be equipped with a nuisance call determination function, but all telephone conversations may be sent to the call center after the conversation ends, and the call center may be left to determine whether or not the call is a nuisance call. In this case, the conversation content analysis unit 2-7 in FIG. 2 is not necessary. If the personal computer 1-2 is equipped with software for advanced nuisance call recognition equivalent to that of the call center, the personal computer can have the same recognition ability as the voice recognition unit of the call center.

  The called party himself / herself may be set as a nuisance call on the operation display unit 2-13 at his / her own discretion while having a conversation. In addition, the voice recognition unit 4-1 of the call center 1-5 can cope with a change in words from a caller of a nuisance call such as a transfer fraud. For example, from the time when "Mom, help me," "I forgot to put my niece on the train, but there was money in the company." Recently, "The police are watching, For example, please give me money ", but the language dictionary of the speech recognition unit 4-1 is updated from time to time. Since a person judges a conversation that could not be judged by the voice recognition unit 4-1, the person can also know the weaknesses of the performance of the voice recognition function at any time, and the voice recognition by knowing the words (weak points) that could not be recognized. It is possible to improve the capacity of the department, that is, to update the language dictionary at any time, and the nuisance call determination function of the call center 1-5 is of the highest quality. The speech recognition unit 4-1 of the call center 1-5 expands the language dictionary just by inputting words, so that the person can recognize from the analysis result of the analysis unit 4-2 by the person. Just enter new words that didn't exist and the best quality will be made.

  This updated voice recognition function can be downloaded to the telephone 1-1 as software if necessary. Of course, it is necessary to investigate in advance the memory capacity and processing capacity of the telephone set 1-1, as in the case of a software update of a personal computer. For this investigation, the serial number of the telephone 1-1 may be used as basic information. Since the telephone 1-1 transmits a serial number when making a determination request to the call center 1-5 as to whether it is a nuisance call, the call center 1-5 has a history of serial numbers corresponding to the latest telephone number of the telephone 1-1. It is owned and managed by the management unit 4-5. FIG. 7 shows a signal format between the call center 1-5 and the telephone 1-1 in this case. FIG. 7A shows a signal for transmitting updated software from the call center 1-5, and FIG. 7B shows a signal for returning whether the reception result of the software is OK or NG. If NG is returned, it will be sent again. If NG is returned even if it is sent again, it is determined whether or not to continue the update by talking with the telephone owner by telephone.

 Next, facsimile transmission / reception will be described.

  In the case of transmission, when a document is set on the printer / scanner 1-3 and a scan button (not shown) on the printer / scanner 1-3 is pressed, the scanned signal is sent to the printer / scanner 1-3. The data is sent from a built-in WiFi circuit (not shown) to the WiFi circuit 2-11 of the telephone set 1-1. This signal format is generally a signal format used in a personal computer such as JPEG, and is different from a signal format (MH signal, etc.) for fax transmission. Therefore, it is converted into a facsimile signal format by the image conversion unit 2-8. The signal is temporarily stored in the FAX data portion of the data memory 2-4. When a destination telephone number is input by dialing operation (not shown) of the telephone 1-1, a fax signal in the data memory 2-4 is transmitted by the communication control unit 2-3 according to the facsimile protocol. Signal formats such as the facsimile protocol and MH are well known in the ITU recommendation, which is an international standard, and thus description thereof is omitted here.

  In the case of fax reception, the received signal is accumulated in the FAX data portion of the data memory 2-4, converted into a printer signal format by the image conversion portion 2-8, and sent from the WiFi circuit 2-11 to the printer / scanner 1-3. Sent to and printed. Various signal formats such as MH and MR are defined in the ITU recommendation as the facsimile signal format, but here, if limited to only the default MH signal, the burden on the image conversion unit 2-8 is reduced. It becomes lighter. The FAX data shown in the memory configuration of FIG. 3 is automatically deleted after the FAX transmission is completed for the read data and after the printing is completed for the read data.

  As an incidental effect of the nuisance call countermeasure according to the present invention, as described above, when the call center 1-5 cannot determine the voice recognition unit 4-2, the words that the person has determined and could not determine It has been added to the language dictionary. As a result, the function of the speech recognition unit is improved by using raw data of actual telephone conversations. Therefore, the present invention is intended to develop a speech recognition function with the highest quality and high practicality. Can contribute.

  Household telephones that are equipped with a fax function and answering machine function are standard, but the new telephone products according to the present invention can create a new boom as a new generation of telephones, activating the telephone market. To do. In addition, it is possible to refuse wire fraud and undesired solicitation, and it is possible to eliminate not only crime prevention but also discomfort of telephone users.
