Description

[Technical Field]

[0001] The present invention relates to a technology for making an auto-call to a mobile phone number and sending a message depending on the response of the caller. [Background technology]

[0002] In recent years, an increasing number of companies are introducing auto-calling for telephone sales. One example is sending an SMS if a customer responds after making an auto-call. Also, when using auto-calling, multiple users can be called from a single number. This can reduce equipment costs.

[0003] In addition, many customers are unable to answer the phone when you make an auto call, and in such cases, the customer may call back. When a customer calls back, it is effective to send an SMS depending on the customer's response, just as when you make an auto call.

[0004] With this type of auto-call system, the same SMS may be sent multiple times when the customer calls and when the call is returned, or the system may call back customers even if they have received a return call, causing customer annoyance. Also, when using one number to make auto-calls for multiple users, there is a risk of misidentifying which user the call is for.

[0005] The following technologies are known for systems related to autocalls. Patent Document 1 discloses a system that determines the usage status of a specified phone number from response information obtained by an automatic call and delivers a short message created based on that usage status to the user's terminal. Patent Document 2 discloses a system that makes an automatic call and changes the response depending on the callee's response. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE INVENTION

[0019] Hereinafter, examples of the first embodiment of the present invention will be described. (Example: First embodiment)

[0020] FIG. 1 is a diagram showing the configuration of an automatic calling system 1 in the first embodiment.

[0021] The automatic call system 1 is connected to a user terminal, a customer terminal 2, and a customer terminal 3 via a communication network.

[0022] The communication network may be a telephone network, a dedicated line, a LAN (Local Area Network), the Internet, or a combination of these.

[0023] The automatic call system 1 includes a telephone number storage unit 11, an automatic call sending unit 12, a message sending unit 13, a message sent telephone number recording unit 14, a message sent determination unit 15, an incoming call response unit 16, a response information recording unit 17, an incoming call handled telephone number recording unit 18, and a conditional automatic call sending unit 19.

[0024] The devices that perform processing corresponding to each component of the automatic call system 1 (telephone number storage unit 11, automatic call sending unit 12, message sending unit 13, message sent telephone number recording unit 14, message sent determination unit 15, incoming call handling unit 16, response information recording unit 17, incoming call handled telephone number recording unit 18, and conditional automatic call sending unit 19) may be located in physically separate locations.

[0025] The telephone number storage unit 11 stores telephone numbers for making auto-calls.

[0026] The automatic telephone calling unit 12 automatically calls the telephone number stored in the telephone number storage unit 11 .

[0027] The message sending unit 13 sends a message to the telephone number from which the automatic call sending unit 12 made a call.

[0028] The message transmission telephone number recording unit 14 records the destination telephone number to which the message is sent from the message sending unit 13 .

[0029] The message transmission determination unit 15 checks the telephone number recorded in the message transmission telephone number recording unit 14 and determines whether a message has been sent to that telephone number.

[0030] The incoming call handling unit 16 handles incoming calls. Handling an incoming call includes any one of the following actions or any combination thereof: ignoring the incoming call, transferring the incoming call, sending a message to the caller, hanging up without starting the call, starting the call and playing audio, and starting the call and hanging up without playing audio. The incoming call handling unit 16 changes the action to handle the incoming call or the audio to play while handling the call, depending on the determination result of the message transmission determination unit 15.

[0031] The response information recording unit 17 records the response information of the call originated by the automatic call originating unit 12 .

[0032] The call handling completed telephone number recording unit 18 records the telephone numbers that have been handled by the call handling unit 16 .

[0033] The conditional automatic call sending unit 19 automatically sends a call to a telephone number that satisfies certain conditions, including a condition regarding response information of the sent call and a condition regarding whether the call has been answered. (First embodiment: sending a message in response to an auto-call and handling subsequent incoming calls)

[0034] An example of a message transmission process in response to an auto-call by the automatic call system 1 and a subsequent call handling process will be described below.

[0035] The telephone number storage unit 11 stores the destination telephone number "09012345678" to which an auto-call is to be made.

[0036] The automatic telephone calling unit 12 automatically makes a call to the telephone number “09012345678” stored in the telephone number storage unit 11 .

[0037] The message sending unit 13 sends a message to the telephone number "09012345678" that was called from the automatic call sending unit 12.

[0038] FIG. 2 is a diagram showing an example of a message transmitted by the message transmission unit 13. As shown in FIG.

[0039] The message sending unit 13 holds the message body, "Thank you for your interest in our telephone recording service. Our telephone recording service records all telephone calls for 3,000 yen per month. For details, please see the following URL: https: / / xxx.xxx / ."

[0040] The message transmission telephone number recording unit 14 records the destination telephone number "09012345678" to which the message was sent from the message sending unit 13, and the sending date and time "2023 / 12:05:00".

[0041] The message transmission determination unit 15 checks the telephone number recorded in the message transmission telephone number recording unit 14 to determine whether a message has been sent to the telephone number "09012345678" and, if it has been sent, stores "sent."

[0042] The incoming call handling unit 16 receives an incoming call from the customer terminal 3 "09012345678" and handles the incoming call.

[0043] FIG. 3 is a flowchart showing the flow from the determination result of the message transmission determination unit 15 to the handling of an incoming call by the incoming call handling unit 16.

[0044] Based on the judgment result "sent" of the message sent judgment unit 15, the incoming call response unit 16 selects the response method for an incoming call as follows: "Start the call and play the voice message 'Thank you for calling. We have sent you a message with information about our telephone recording service, so please take a look.'"

[0045] In a modification of this embodiment, when the message transmission determination unit 15 determines that the message has been sent, the incoming call handling unit 16 may transfer the incoming call to an operator. Alternatively, the incoming call may not be answered or may be immediately disconnected without playing any audio.

[0046] Furthermore, this embodiment may be modified so that when the message transmission determination unit 15 determines that the message is "not transmitted," the incoming call response unit 16 responds by transmitting the message without playing back the audio.

[0047] Furthermore, this embodiment may be modified to have a function that automatically calls at a pre-specified date and time if a call made by the automatic call making unit 12 does not connect.

[0048] Furthermore, this embodiment may be modified so that the method of response to an incoming call in the incoming call response unit 16 can be changed depending on whether the call is from the person who placed the call from the automatic call sending unit 12.

[0049] Furthermore, this embodiment may be modified so that the decision on how to respond to an incoming call in the incoming call response unit 16 can be changed depending on whether an incoming call has already been received.

[0050] Furthermore, this embodiment may be modified so that the method of handling an incoming call in the incoming call handling unit 16 can be changed depending on whether a message has been sent within a certain period of time since the time of the call.

[0051] Furthermore, this embodiment may be modified so that the decision on how to respond to an incoming call in the incoming call response unit 16 is made depending on whether or not a call was made from the automatic call sending unit 12 but a message was not sent. (First embodiment: conditional repeat call)

[0052] FIG. 4 is a diagram showing the response records held by the response information recording unit 17. As shown in FIG.

[0053] The response information recording unit 17 records the response information "unreachable" for the call "09012345678" sent by the automatic call sending unit 12 and the call date and time "2023 / 12:00:00".

[0054] The handled call number recording unit 18 records the handled call number "09012345678" in the call handling unit 16.

[0055] FIG. 5 is a flowchart showing the flow of the conditional automatic call sending unit 19 making a call.

[0056] The conditional automatic telephone call unit 19 refers to the response information recording unit 17 to extract the response information "unreachable" for the outgoing call "09011111111" and refers to the answered telephone number recording unit 18 to extract "no answer record", and in response to this, selects "re-auto call" and automatically makes a call to the telephone number "09011111111".

[0057] This embodiment may be modified so that one of the conditions for the conditional automatic telephone call unit 19 to select "re-auto call" is whether or not a call made from the automatic telephone call unit 12 in the past was connected but was disconnected within a certain time.

[0058] Furthermore, this embodiment may be modified so that one of the conditions for the conditional automatic telephone call unit 19 to select "re-auto call" is whether or not a call made from the automatic telephone call unit 12 in the past was connected but went to voicemail.

[0059] An example of the second embodiment of the present invention will be described below. (Example: Second embodiment)

[0060] FIG. 6 is a diagram showing the configuration of an automatic calling system 1 in the second embodiment.

[0061] The communication network may be a telephone network, a dedicated line, a LAN (Local Area Network), the Internet, or a combination of these.

[0062] The automatic call system 1 includes a telephone number storage unit 11, an automatic telephone call sending unit 12, a message sending unit 13, an incoming call handling unit 16, an incoming call handling method storage unit 110, an automatic call record storage unit 111, a telephone call identification unit 112, an incoming call handling method determination unit 113, and an incoming call handling unit after user identification 114.

[0063] The devices that execute the processing corresponding to each component of the automatic call system 1 (telephone number storage unit 11, automatic telephone call sending unit 12, message sending unit 13, incoming call handling unit 16, incoming call handling method storage unit 110, automatic call record storage unit 111, telephone call identification unit 112, incoming call handling method determination unit 113, and incoming call handling unit after user identification 114) may be located in physically separate locations.

[0064] The incoming call handling method storage unit 110 stores an incoming call handling method for each user. The incoming call handling methods include any one or a combination of the following actions: ignoring the incoming call, transferring the incoming call, sending a message to the caller, hanging up without starting the call, starting the call and playing audio, and starting the call and hanging up without playing audio.

[0065] The automatic call record holding unit 111 records the user identifier, the caller's telephone number, and the callee's telephone number when the automatic call calling unit 12 makes a call.

[0066] When the incoming call handling unit 16 receives an incoming call, the telephone call identification unit 112 refers to the automatic call record storage unit 111 to identify the last telephone call with the caller telephone number as the destination and the destination telephone number as the caller.

[0067] The incoming call handling method determination unit 113 refers to the incoming call handling method storage unit 110 and determines a method of handling an incoming call corresponding to the user identifier of the user who made the call identified by the outgoing call identification unit 112 .

[0068] After identifying the user, the incoming call handling unit 114 handles the incoming call in accordance with the handling method determined by the incoming call handling method determining unit 113 . (Second embodiment: handling incoming calls for each user)

[0069] An example of the process of handling incoming calls for each user when there are multiple users using the automatic calling system 1 will be described below.

[0070] 7 is a diagram showing the handling method rules stored in the incoming call handling method storage unit 110. The incoming call handling method storage unit 110 stores the handling method for an incoming call for each user, and stores "Handling A" as the handling method for user "Company A" with user identifier "1", and "Handling B" as the handling method for user "Company B" with user identifier "2".

[0071] The incoming call handling method storage unit 110 stores, as "Response A," "Condition 1: If the call is unsuccessful and the message has not been sent, a re-auto call will be made: 'Thank you for calling back. We are offering information about SMS marketing. If you are interested, please press 1.' Condition 2: If the call is unsuccessful and the message has already been sent, 'Thank you for calling. We have sent you a message with information about SMS marketing, so please take a look.'" and, as "Response B," stores, "Condition 1: If the call is unsuccessful and the message has not been sent, a re-auto call will be made: 'Thank you for calling back. We are offering information about our phone recording service, which records all phone calls for 3,000 yen a month. If you are interested, please press 1.' Condition 2: If the call is unsuccessful and the message has already been sent, 'Thank you for calling. We have sent you a message with information about our phone recording service, so please take a look.'"

[0072] When a call is made from the automatic call making unit 12, the automatic call record keeping unit 111 records the user name "Company B", user identifier "2", caller telephone number "05012345678", callee telephone number "09012345678", and call date and time "2023 / 12:00:00".

[0073] When the incoming call handling unit 16 receives an incoming call, the telephone call identification unit 112 refers to the automatic call record storage unit 111 to identify the last telephone call "2023 / 12:00:00" with the caller's telephone number "09012345678" as the call destination and the caller's telephone number "05012345678" as the call source.

[0074] 9 is a flowchart showing the flow up to the decision of the handling method by the incoming call handling method decision unit 113. The incoming call handling method decision unit 113 refers to the incoming call handling method storage unit 110 and decides on the handling method "Handling B" for the incoming call corresponding to the user identifier "2" of the user "Company B" who made the call "2023 / 12:00:00" identified by the call outgoing call identification unit 112.

[0075] The call handling unit 114 after identifying the user handles the call as the "Response B" response method for incoming calls determined by the call handling method determination unit 113, and responds in accordance with the following: "Condition 1: If the call is unsuccessful and no message has been sent, re-auto-call: 'Thank you for calling back. We offer a telephone recording service that records all calls for 3,000 yen per month. If you are interested, please press 1.' Condition 2: If the call is unsuccessful and a message has been sent, 'Thank you for calling. We have sent you a message with information about our telephone recording service, so please take a look.'"

[0076] This embodiment may be modified so that the voice to be transmitted and the message text to be sent are stored for each user.

[0077] Furthermore, this embodiment may be modified so that if there is no outgoing call and the outgoing call identifying unit 112 cannot identify the last outgoing call, a predetermined response may be taken as a response to an incoming call.

[0078] Furthermore, this embodiment may be modified so that when the call identification unit 112 identifies the last call, only calls made a certain time ago or later are considered as targets. [Industrial Applicability]

[0079] This is an automatic call system and program that enables the sending of messages in response to answering information for auto-calls or subsequent call-backs, and also enables the system to find the appropriate user and respond to the call when there is a call-back from multiple clients.It can be used by companies that handle phone calls.
