The embodiment described below is only an example, and the embodiment to which the present invention is applied is not limited to the following embodiment. In the following description, a voice call is described as an example, but this embodiment can also be applied to a videophone.

<System configuration, overview>
FIG. 1 is a diagram illustrating a configuration example of a communication system according to an embodiment. The communication system includes a call processing system 10, a caller's terminal 20a, a callee's terminal 20b, and an administrator's terminal 20c. In the example of FIG. 1, one each of the caller's terminal 20a, the callee's terminal 20b, and the administrator's terminal 20c is illustrated, but for convenience, there may be a plurality of each. In the example of FIG. 1, the caller's terminal 20a, the callee's terminal 20b, and the administrator's terminal 20c are shown separately, but the caller's terminal 20a, the callee's terminal 20b, The administrator terminal 20c has the same function. In the following description, when the terminal 20a, the terminal 20b, and the terminal 20c are not distinguished, they are simply described as “terminal 20”.

  The call processing system 10 has a function of performing call processing for connecting a call transmitted from the caller's terminal 20a to the callee's terminal 20b. The call processing system 10 is assumed to be a system that is provided by a fixed telephone carrier or a mobile phone carrier and includes an exchange, a base station, a subscriber management device, and the like. However, the call processing system 10 may be a device used to configure a small-scale telephone network, such as PBX (Private Branch Exchange). That is, the call processing system 10 may be configured by a single device or a combination of a plurality of devices.

  The terminal 20 is a telephone having a call function. The terminal 20 is, for example, a mobile phone, a fixed phone, a smartphone, a tablet terminal, an IP phone, or the like.

  In the present embodiment, a user or a manager of the user (for example, an elderly user's child, etc.) tells the call processing system 10 a telephone number (white list) that permits incoming calls and a telephone number that refuses incoming calls (white numbers). A personal phone book including a black list is registered in advance. The phone number (white list) that permits incoming calls is, for example, the phone number of the user's family, and the phone number (black list) that rejects incoming calls is, for example, determined that the user has been a nuisance call in the past. This is a phone number that the user wishes to forcibly refuse incoming calls without answering.

  In the call processing system 10 according to the embodiment, the calling number of the incoming call (the telephone number of the caller) is not included in the user's personal phone book (that is, included in both the white list and the black list). If not), a predetermined talkie (for example, recording a call) is transmitted to the terminal that is the source of the incoming call. As a result, it is possible to give a deterrent effect against persistent sales, wire fraud, etc. to a caller who makes annoying calls over and over with different phone numbers.

  In addition, the call processing system 10 according to the embodiment actually records the incoming call, and from the calling party number not included in the user's telephone directory to the terminal 20c of the user (the called party) administrator. Operates to notify that an incoming call has been received. In this way, the administrator can confirm the content of the conversation between the user (the incoming caller) and the caller (the caller making a nuisance call) by playing the recorded incoming call. Depending on the content of the conversation, it is possible to take action such as warning the user (for example, there is a possibility of fraud) or adding it to the black list of the user's phone book. .

<Functional configuration>
FIG. 2 is a diagram illustrating an example of a functional configuration of the call processing system according to the embodiment. The call processing system 10 according to the embodiment includes a call processing unit 101, a talkie transmitting unit 102, a notification unit 103, a personal phone book operation unit 104, a phone book management unit 105, and a storage unit 106. Note that FIG. 2 shows only functional units particularly relevant to the embodiment of the present invention in the call processing system 10, and at least has functions not shown in order to perform call processing.

  The call processing unit 101 has a function of performing various call processes for realizing a call performed between the terminals 20. More specifically, the call processing unit 101 transmits / receives control signals (common line signal, SIP, etc.) used when establishing a call between the terminals 20, relays voice data transmitted / received between the terminals 20, and the like. Do. Further, the call processing unit 101 has a function of relaying a talkie transmitted from the talkie transmitting unit 102 to a predetermined terminal 20 and a function of recording a call.

  The talkie transmitting unit 102 has a function of transmitting (outputting) a predetermined talkie (for example, a talkee stored in warning talkie information, for example, recording a call) according to an instruction from the call processing unit 101. Note that the talkie transmitting unit 102 may be included in the call processing unit 101.

  The notification unit 103 has a function of detecting that an incoming call has been received from a calling number that is not included in the user's personal telephone directory, and notifying the administrator's terminal 20c.

  The personal phone book operation unit 104 has a function of performing various operations (registration, deletion, update, etc.) on the personal phone book in response to an instruction from the user or the administrator of the user.

  The phone book management unit 105 has a function of merging information stored in each user's personal phone book into the black shared phone book. The contents of the black shared telephone directory will be described later.

  The phone book management unit 105 uses each of the information stored in the black shared phone book as a black list of specific calling numbers (for example, calling numbers of records whose degree of risk is greater than a predetermined level). You may have the function to register to a telephone directory automatically. Further, when registering the specific record as a black list in the personal telephone directory, the telephone directory management unit 105 may inquire the administrator and register it after obtaining permission from the administrator.

  The storage unit 106 stores administrator information, a personal phone book, a black shared phone book, and warning talkie information. The storage unit 106 can be realized using a storage device (memory, HDD, or the like) included in the call processing system 10.

  FIG. 3 is a diagram illustrating an example of the administrator information. The manager information is information that associates the user with the manager of the user. In the example of FIG. 3, the administrator of user A is X, and the administrator of user B is Y.

FIG. 4 is a diagram illustrating an example of a personal telephone directory. In the personal phone book, a telephone number (white list) that permits incoming calls and a telephone number (black list) that refuses incoming calls are registered for each user. In the example of FIG. 4, only the personal phone book of the user A is shown, but the personal phone books of other users (users B, C, etc.) can also be registered.
“TEL” is a telephone number of a transmission source, and “list” is information for identifying whether the telephone number of the transmission source is a white list or a black list. In the example of FIG. 4, TEL1 and TEL2 are white lists, and TEL30 and TEL40 are black lists.

  “Category” is information (in this embodiment, sales or fraud is assumed) indicating what kind of purpose the telephone number of the caller is the telephone number of the other party making the nuisance call. “Number of incoming calls” is information indicating the cumulative number of incoming calls from the telephone number of the caller. In the example of FIG. 4, it is shown that an incoming call is received twice from the TEL 30 and once from the TEL 40.

  The information registered in the “list” and “category” is input at the discretion of the user or the administrator of the user when the telephone number of the caller is newly registered. The “number of incoming calls” is automatically updated by the call processing unit 101. Further, the “category” and the “number of incoming calls” may not be stored for the telephone numbers of the white list.

  FIG. 5 is a diagram illustrating an example of a black shared telephone directory. In the black shared phone book, records registered as black lists in each user's personal phone book are merged and registered. The merge process is performed regularly or at a predetermined timing by the telephone directory management unit 105.

  The “number of incoming calls (total)” stores the total “number of incoming calls” of each record in each user's personal phone book. For example, in FIG. 5, the number of incoming calls (total number) of the TEL 30 is shown as 100 times, but this is registered in the black list of the personal phone book of each user (users A, B, C,...). This indicates that the total “number of incoming calls” of the TEL 30 is 100.

  “Elapsed time” indicates an elapsed time from the time when the record is first registered (merged) in the black shared telephone directory. The “risk level” indicates the risk level of the telephone number of the caller, and the risk level determined by the telephone directory management unit 105 is stored.

  Here, a specific example when the telephone directory management unit 105 determines the “risk level” will be described. For example, the telephone directory management unit 105 may determine the “risk level” by comparing the “number of incoming calls (total number)” with a predetermined threshold. As a specific example, the telephone directory management unit 105 determines the risk level 1 when the number of incoming calls is 10 or less, determines the risk level 2 when the number is 11 to 50, and determines the risk level 3 when the number is 51 or more. You may make it do. It is assumed that a partner who makes a nuisance call holds a plurality of telephone lines and makes calls to various users by using these plural telephone lines. Therefore, it is considered that the risk degree can be statistically determined by accumulating the number of incoming calls in each user's black list. The predetermined threshold may be a different number of times for each “category”. For example, when the “category” is fraud, the threshold may be set lower (that is, the degree of risk is determined to be higher than sales) as compared to sales.

  Further, the telephone directory management unit 105 calculates the number of incoming calls per predetermined unit time (for example, one day) from the “number of incoming calls (total)” and the “elapsed time”, and determines the number of incoming calls per predetermined unit time and the predetermined number of times. You may make it determine "risk degree" by comparing with a threshold value. As a specific example, the telephone directory management unit 105 determines a risk level 1 if the number of incoming calls per day is 3 or less, determines a risk level 2 if the number of incoming calls is 4 to 10 times, and indicates a risk level 11 times or more. The degree 3 may be determined. The predetermined threshold may be a different number of times for each “category”. For example, when the “category” is fraud, the threshold may be set lower (that is, the degree of risk is determined to be higher than sales) as compared to sales.

  The telephone directory management unit 105 may determine and update the “risk level” at a predetermined timing (for example, every time merge processing is performed).

  FIG. 6 is a diagram illustrating an example of warning talkie information. The warning talkie information stores a talkie to be transmitted according to the degree of danger. “Category” and “Danger Level” of the warning talkie information correspond to “Category” and “Danger Level” of the black shared telephone directory.

<Operation example of communication system>
(About call processing)
FIG. 7 is a sequence diagram illustrating an operation example of the communication system according to the embodiment. An example of outgoing / incoming processing performed by the communication system according to the embodiment will be specifically described with reference to FIG. In FIG. 7, it is assumed that the called party is user A. Further, it is assumed that the administrator of user A is the administrator X.

  In step S101, a call is made from the caller's terminal 20a to the callee's (user A) terminal 20b.

  In step S102, the call processing unit 101 of the call processing system 10 confirms that the calling number of the terminal 20a (calling number of the call transmitted from the terminal 20a) is registered in the personal phone book of the user A who is the called party. Determine whether or not. If the calling number of the terminal 20a is registered in the white list of the personal phone book of the user A, the process proceeds to step S103. When the calling number of the terminal 20a is registered in the black list of the personal phone book of the user A, the process proceeds to step S111. If the calling number of the terminal 20a is not registered in the white list or black list of the personal phone book of the user A, and is not registered in the black shared phone book, the process proceeds to step S121. . If the calling number of the terminal 20a is not registered in the white list or black list of the personal phone book of the user A, but is registered in the black shared phone book, the process proceeds to step S131.

  In step S103 and step S104, the call processing unit 101 transmits a ring tone to the caller terminal 20a and the callee terminal 20b. In step S105, the call processing unit 101 establishes a call between the caller's terminal 20a and the callee's terminal 20b, and a call is started between the caller and the callee (user A).

  In step S111, the call processing unit 101 instructs the talkie transmitting unit 102 to output a talkie that “the incoming call is rejected”, and uses the talkie output from the talkie transmitting unit 102 as the caller terminal 20a. Send to. Further, the call processing unit 101 disconnects the call after transmitting the talk key.

  In step S121, the call processing unit 101 instructs the talkie transmitting unit 102 to output a talkie that “the call will be recorded”, and uses the talkie output from the talkie transmitting unit 102 as the caller terminal 20a. Send to.

  In step S122, the call processing unit 101 of the call processing system 10 transmits a ringing tone to the terminal 20b of the called party.

  In step S123, the call processing unit 101 establishes a call between the caller's terminal 20a and the callee's terminal 20b, and a call is started between the caller and the callee (user A). The call processing unit 101 records the call and stores the recorded data in the storage unit 106.

  In step S124, the notification unit 103 refers to the administrator information, identifies the administrator X of the user A, and receives an incoming call from a calling number that is not registered in the white list or black list of the user A. This is notified to the terminal 20c of the manager X.

  In step S131, the call processing unit 101 instructs the talkie transmitting unit 102 to output a talkie that “the call will be recorded”, and uses the talkie output from the talkie transmitting unit 102 as the caller terminal 20a. Send to.

  In step S132, the call processing unit 101 refers to the black shared telephone directory and searches for a category and a risk level corresponding to the calling number of the terminal 20a. Subsequently, the call processing unit 101 notifies the Talkie transmitting unit 102 of the searched category and risk level. The talkie transmitting unit 102 refers to the warning talkie information and outputs a talkie corresponding to the category and the risk level notified from the call processing unit 101. The call processing unit 101 transmits the talkie output from the talkie transmitting unit 102 to the terminal 20b of the called party.

  In step S133, the call processing unit 101 establishes a call between the caller's terminal 20a and the callee's terminal 20b, and a call is started between the caller and the callee (user A). The call processing unit 101 records the call and stores the recorded data in the storage unit 106.

  In step S134, the notification unit 103 refers to the administrator information, identifies the administrator X of the user A, and receives an incoming call from a calling number that is not registered in the white list or black list of the user A. This is notified to the terminal 20c of the manager X. Note that the notification unit 103 and the talkie transmitting unit 102 may output the same talkie (the talkie corresponding to the category and the degree of danger notified from the call processing unit 101) in the notification in the notification in step S132. Good.

(About notification to the administrator)
In the outgoing / incoming processing described above, if the calling number of the terminal 20a is not registered in the white list or black list of the personal phone book of the user A, a notification to the administrator X (step S124 or step S134) is made. It will be done each time. In this embodiment, since the recording of the call is performed at the same time when the notification is made, the administrator X confirms the content of the recorded call and alerts the user A as necessary. be able to.

  However, if there are many cases where it is judged that the recorded call is not particularly suspicious even if the recorded call is confirmed, it becomes troublesome for the administrator to check the recorded call every time. May miss a simple phone call.

  Therefore, in the present embodiment, in the processing procedure of step S124 and step S134, the notification unit 103 of the call processing system 10 may notify the administrator only when a predetermined condition is satisfied.

[Example of predetermined condition (1)]
In general, it is assumed that there is a low possibility of being fraudulent with a phone call received for the first time. Therefore, the notification unit 103 may notify the manager when the same number is received from the same calling number for the same number of times or more (for example, twice or more). The set number of times may be set as the number instructed by the administrator, or may be a predetermined number. Further, the set number of times may be reset at an arbitrary timing according to an instruction from the administrator.

[Example of predetermined conditions (2)]
In general, it is assumed that a person who conducts fraud or sales often calls many times in a short time using the same or different calling number. Therefore, the notification unit 103 notifies the administrator when the same caller from the same or different calling number receives a set number of times (for example, 10 times a week) or more within a predetermined period. Notification may be performed. The predetermined period and the set number of times may set a period and the number of times instructed by the administrator, or may be a predetermined period and the number of times. Further, the predetermined period and the set number of times may be reset at an arbitrary timing according to an instruction from the administrator.

[Example of predetermined conditions (part 3)]
In general, there is a high possibility that a specific keyword is used when fraud or the like is performed. Therefore, the notification unit 103 determines that a specific keyword is included in a call performed in the procedure of step S123 or step S133. You may make it notify to an administrator, when said. The specific keyword is, for example, “transfer”, “ATM”, “phone number has changed”, “legal means”, or the like.

[Example of predetermined condition (4)]
In general, when fraud or sales are performed, it is assumed that the call time is long. Therefore, the notification unit 103 may notify the administrator when a predetermined time or more has elapsed since the start of the call performed in the processing procedure of step S123 or step S133.

  Examples of the predetermined conditions described above (parts 1 to 4) may be arbitrarily combined. For example, the notification unit 103 may notify the administrator when any one of the predetermined condition examples (parts 1 to 4) is satisfied, or the predetermined condition example (parts 1 and 4). When both of 3) are satisfied, or when both of the examples of the predetermined conditions (parts 2 and 3) are satisfied, the administrator may be notified.

(About alerting recipients)
When notifying the administrator in the processing procedure of step S124 and step S134, the notification unit 103 may alert the callee in addition to the administrator (or instead of the administrator). Good. For example, the notification unit 103 may alert the callee by notifying the callee of a call waiting (for example, sending a sound of “pu, pu, pu”). .

  In addition, the notification unit 103 may perform the alert when the user satisfies any one (or a plurality) of the above-described predetermined condition examples (1 to 4). The predetermined condition used for determining whether or not to notify the administrator may be different from the predetermined condition applied to determining whether or not to perform the alert. For example, the notification unit 103 notifies the administrator when any one of the predetermined condition examples (parts 1 to 4) is satisfied, and further, both of the predetermined condition examples (parts 2 and 3). The callee may be alerted only when the condition is satisfied.

(Registration to whitelist and blacklist)
In the embodiment described above, the user or the administrator of the user registers the personal telephone directory. Therefore, if the administrator determines that there is no particular problem with the recorded call (not a suspicious call), or if it is determined that there is a problem (is a suspicious call), the calling number associated with the call is A mechanism that can be easily registered in the white list or black list of the book may be provided.

  FIG. 8 is a sequence diagram illustrating an example of a processing procedure for realizing simple registration in the white list or black list. In the following description, it is assumed that the administrator X is about to check the recorded call in response to the notification by the processing procedure of steps S124 and S134 of FIG.

  In step S201, the administrator X performs a push operation for reproducing the recording in order to confirm the recorded call.

  In step S202, the call processing unit 101 of the call processing system 10 plays back the recorded call.

  In step S203, when the manager X determines that the call is not particularly problematic (not a suspicious call), the manager X performs a push operation (for example, “1”) for registering the calling number of the call in the white list. . In addition, when the manager X determines that the call has a problem (a suspicious call), a push operation for registering the calling number of the call in a blacklist (for example, “ 2 ”to“ 9 ”).

  In step S204, the personal phone book operation unit 104 of the call processing system 10 registers the recorded call origination numbers in the personal phone book of the user A as a white list or a black list.

<Supplement of embodiment>
As described above, each functional unit included in the call processing system 10 according to the embodiment is realized by executing a program corresponding to a process executed in the call processing system 10 using hardware resources such as a CPU and a memory. It is possible. Further, the program can be stored in a storage medium.

  In the embodiment, the call processing unit 101, the talkie transmitting unit 102, and the notification unit 103 are examples of call control means.
