  The present invention provides a technique that improves on the conventional white list method. Specifically, an SNS type access control service is provided that manages a user authentication list (white list) on the network side and controls call rejection / acceptance based on the connection between the authentication lists on the network side. Hereinafter, an embodiment for carrying out the present invention will be described with reference to the drawings.

[First Embodiment]
FIG. 1 is a diagram illustrating a functional block configuration of an access control apparatus 1 according to the first embodiment. The access control device 1 operates by connecting inside or outside a switch, a call control server, or the like installed in the Internet network, carrier network, etc., and includes an authentication list DB 11 and an access control unit 12. .

  The authentication list DB 11 is configured to store a user authentication list. The authentication list is a so-called white list in which the telephone numbers of allowed users that are allowed to be received by the user are recorded. Registered in association with a user ID for identifying the user. As the authentication list, an authentication list registered in the user's telephone terminal may be used, or an authentication list directly input to the authentication list DB 11 by the user may be used. In addition, a user's telephone terminal is a fixed telephone, a mobile phone, a smart phone etc., for example.

  When the access control unit 12 receives an outgoing call from a telephone terminal, the access user's telephone number is registered in the incoming user's authentication list or registered in the authentication list associated with the user registered in the authentication list. Are sequentially determined, and based on the determination result, incoming call rejection / acceptance to the incoming user is controlled.

  Next, an access control operation performed in this embodiment will be described with reference to FIG. Instead of simply performing access control based on the authentication list of the incoming user as in the conventional white list method, access control is further performed using an authentication list related to the user authenticated by the incoming user.

  First, when an outgoing call is accepted from a predetermined telephone terminal in step S101, the telephone number of the calling user included in the outgoing call is acquired in step S102, and the calling user's telephone number is registered in the incoming user authentication list. It is determined whether or not it has been done. If the result of this determination is that it has been registered in the incoming user's authentication list, the incoming user himself / herself allows incoming calls from the outgoing user, and therefore proceeds to step S104 to allow incoming calls to the incoming user.

  On the other hand, if the calling user's telephone number is not registered in the receiving user's authentication list, the process proceeds to step S103. Next, it is determined whether or not the telephone number of the calling user is registered in the authentication list related to the user registered in the authentication list of the incoming user. For example, as shown in FIG. 3, when the telephone number Z of the calling user C is not registered in the authentication list A of the incoming user A, refer to the authentication list B authenticated by the user B registered in the authentication list A Then, it is confirmed whether it is registered in the authentication list B.

  If the telephone number Z of the calling user C is registered in the authentication list B as a result of the determination, the receiving user A is regarded as accepting an incoming call from the calling user C, and the process proceeds to step S104. An incoming call to incoming user A is allowed. On the other hand, if the incoming user A is not registered in the authentication list B related to the authenticated user B, the process proceeds to step S105, where the incoming user A is regarded as not allowed even if the community range of the incoming user A is included. Reject incoming calls to A.

  Thus, in addition to the incoming user authentication list, access control is further performed using the authentication list related to the user authenticated by the incoming user, so that the usability of the telephone service can be improved and the access control can be flexibly implemented.

  It is also possible to further expand the community range of incoming users. For example, when the telephone number Z of the calling user C is not registered in the authentication list B of the user B in step S103, it is subsequently registered in the authentication list D related to the other user D registered in the authentication list B. It is determined whether or not. If it is not registered in the authentication list D, it is further determined whether or not it is registered in the authentication list E related to another user E registered in the authentication list D.

  Further, the community range of the incoming user, that is, the range of the authentication list associated with the incoming user authentication list (for example, community level, number of authentication lists) may be set on the access control device side, or the incoming user It may be set on the side. In the latter case, for example, a setting method for limiting only to an authentication list related to a registered user registered in its own authentication list, limiting to only the authentication list of the registered user, and a specific user among the registered users A setting method for excluding the authentication list can be considered.

[Second Embodiment]
Next, a second embodiment will be described. In the case of the first embodiment, there is still a trouble for the user to register a telephone number in the authentication list. Therefore, in the present embodiment, the authentication list is generated by diverting existing SNS service information.

  FIG. 4 is a diagram illustrating a functional block configuration of the access control apparatus 1 according to the second embodiment. Compared to the conventional access control device 1, a data acquisition unit 13 and a data conversion unit 14 are further provided.

  The data acquisition unit 13 is configured to connect to the SNS service DB 3 used by the existing SNS service and periodically acquire user friendship information from the SNS service DB 3. In the existing SNS service, a community-type website is provided to promote and support connections between users. A user who uses the service registers friendship information regarding friends, colleagues, classmates, neighbors, and the like in the desired SNS service DB. In the present embodiment, the SNS service DB 3 is used as a general term for the DB.

  The data conversion unit 14 is configured to convert the user friendship information acquired from the SNS service DB 3 into a format that can be used by the access control apparatus 1 and update the authentication list stored in the authentication list DB. .

  Next, an access control operation performed in this embodiment will be described with reference to FIG.

  First, in step S201, the data acquisition unit 13 acquires user friendship information from the SNS service DB 3 used in an existing SNS service. In the friendship relationship information, as described above, names, telephone numbers, and the like of friends who have a friendship relationship with the user are registered.

  Thereafter, in step S202, the data conversion unit 14 converts the acquired user friendship information into a format that can be used in the authentication list DB 11, and adds the converted data to the authentication list registered in the authentication list DB 11. For example, when the user D is registered in the friendship relationship information of the user A, the name and telephone number of the user D are extracted and added to the authentication list of the user A. If the authentication list is not registered in the authentication list DB 11, it is newly registered.

  Thereafter, when an outgoing call is accepted from the telephone terminal, the processing after step S101 described in the first embodiment is executed.

  As described above, the friendship information of the user is acquired from the existing SNS service, converted into a format usable by the access control device 1, and the authentication list in the authentication list DB 11 is updated using the friendship relationship information after conversion. The trouble of the user registering the telephone number in the authentication list can be eliminated, and the usability of the telephone service can be further improved.

  Note that steps S201 and S202 may be periodically repeated, and the authentication list DB 11 may be updated each time. Alternatively, it may be executed when an arbitrary SNS service is started.

[Third Embodiment]
Subsequently, a third embodiment will be described. In the case of the first embodiment or the second embodiment, in order to determine the call rejection / permission based only on the user authentication list, from a good company / organization not registered in the user authentication list. Incoming calls will be rejected. Therefore, in this embodiment, the telephone number of a good company / organization is registered / authenticated on the network side to allow access.

  FIG. 6 is a diagram illustrating a functional block configuration of the access control apparatus 1 according to the third embodiment. The access control device 1 used in the first embodiment is further provided with a good user registration receiving unit 15 and a good user DB 16. Note that these two functional units can be added to the access control apparatus 1 used in the second embodiment.

  The excellent user registration receiving unit 15 is configured to receive registration of a telephone number of a company / organization recognized as a good user.

  The excellent user DB 16 is configured to store a telephone number of a company / organization that has accepted registration. At this time, the telephone number may be stored in association with an ID for identifying the company / organization.

  Next, the access control operation performed in this embodiment will be described with reference to FIG.

  First, in step S301, the good user registration receiving unit 15 receives registration of a telephone number of a company / organization recognized as a good user and registers it in the good user DB. For example, according to the application from the user, the user's superiority is examined by a predetermined organization (for example, carrier, administrative agency, etc.), and it is recognized that the user is excellent based on the administrative guidance or business contents received in the past. Register the phone number of the selected user.

  Next, in step S302, when an outgoing call is accepted from a predetermined telephone terminal, in step S303, the access control unit 12 acquires the telephone number of the calling user included in the outgoing call, and the telephone number of the calling user is It is determined whether or not it is registered in the excellent user DB 16.

  As a result of the determination, if it is registered in the good user DB 16, the process proceeds to step S304, and the incoming call to the incoming user is permitted. On the other hand, if it is not registered in the good user DB 16, the process proceeds to step S305, and the incoming call to the incoming user is rejected.

  In this way, since the telephone number of a good company / organization is registered and access control is performed using the telephone number, the good company / group that provides useful services / information without knowing the user at all. Incoming calls from groups are acceptable.

  Note that access control may be performed using the authentication list described in the first embodiment. For example, the process may proceed to step S303 after step S103, or may proceed to step S102 after step S303.

  As described above, according to each embodiment, the authentication list of each user in which the telephone numbers of allowed users who are allowed to receive calls are registered on the network side, and whether or not the authentication lists are linked on the network side. Based on this, the rejection / acceptance of incoming calls is controlled, so that it is possible to efficiently reject a solicitation talk or a sales call from a malicious trader or the like that the user does not want, and the user can make a call with peace of mind.

  Further, according to the second embodiment, user information used in the SNS service is acquired, the user information is converted into a format that can be used by the access control apparatus 1, and the authentication list is converted using the converted user information. Therefore, it is possible to eliminate the trouble of the user registering the telephone number in the authentication list.

  Furthermore, according to the third embodiment, the registration of the telephone number of a good user who is recognized as good is received and stored, and based on whether the telephone number of the calling user is the telephone number of the good user. Since rejection / acceptance of incoming calls is controlled, incoming calls from good companies / organizations not registered in the user authentication list can be received. In addition, it can be expected that excellent companies / organizations can improve the reliability of users for outgoing calls and acquire more users than before.

  Finally, the access control device 1 described in each embodiment can be realized by a computer having an arithmetic function such as a CPU and a storage function such as a memory. It is also possible to create an access control program for causing a computer to function as the access control apparatus 1 and a storage medium for the access control program.
