Description

  The present invention relates to a technique for restricting the use of communication.

  In recent years, use of home devices such as game machines often involves communication with an external network. Many aspects such as the viewpoint of harm to content children brought by communication from external networks, the continuous use of game machines and smartphones, the continuous use of media equipment such as TV, and the increase of communication usage fees There is a problem.

  There is a method for restricting the use of communication according to the content as a method for restricting the use of communication by the home device. For example, Non-Patent Document 1 considers the influence of content on children and prepares or automatically generates safe content in advance so that the content does not harm children.

  From the viewpoint of use time, there is a method of restricting use by stopping the supply of power to the home device. For example, Non-Patent Document 2 includes a power socket in the device, and after connecting a plug of a device whose usage time is to be limited to the power socket in the device, the usage time is measured by a timer, and power is supplied when the timer expires. To stop.

  From the point of view of usage fees, communication carriers have restricted communication based on the amount of packet communication (see Non-Patent Documents 3 and 4).

  However, in the method of stopping the supply of power to the home device, all functions of the home device are stopped, and there is a possibility that a failure of the device is induced by stopping the supply of power.

  In the method of restricting communication based on the amount of packet communication performed by the communication carrier, the entire packet communication is regulated regardless of the service, so that a call using packet communication cannot be used. Further, when a plurality of devices are connected to the network of the communication carrier via the gateway device, communication of all the plurality of devices is restricted, and communication cannot be restricted individually for each device.

  In addition, although it is expected that a single service is provided across a plurality of devices, conventionally, it has not been considered to limit communication across a plurality of devices.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  The communication control device according to the present embodiment is incorporated in a gateway device that connects a user's home network (LAN) and an external network (WAN) to relay signals from home devices. The communication control device monitors communication on the gateway device, thereby specifying a home device connected to the LAN and limiting the communication use time.

  FIG. 1 is a functional block diagram showing the configuration of the communication control device 1 according to the present embodiment. The communication control apparatus 1 shown in the figure includes a signal transmission / reception unit 11, a signal extraction unit 12, a device identification unit 13, a device dictionary database 14, a restriction processing unit 15, and a restriction rule storage unit 16. Each unit included in the communication control device 1 may be configured by a computer including an arithmetic processing device, a storage device, and the like, and the processing of each unit may be executed by a program. This program is stored in a storage device included in the communication control device 1, and can be recorded on a recording medium such as a magnetic disk, an optical disk, or a semiconductor memory, or provided through a network.

  The signal transmission / reception unit 11 transmits / receives signals between in-home devices connected to the LAN side and between the in-home devices and the WAN. The signal of the home device in which the communication use is restricted is blocked, and the signal of the home device in which the communication use is not restricted is transferred.

  The signal extraction unit 12 extracts a MAC address from the signal received by the signal transmission / reception unit 11 and determines whether or not the device is a registered home device. In the case of an unregistered home device, the extracted MAC address is transmitted to the device specifying unit 13 to specify and register the home device. In the case of a registered home device, the extracted MAC address is transmitted to the restriction processing unit 15 to perform processing related to communication restriction. In the present embodiment, a MAC address is used as an example of information that can uniquely identify a home device on the LAN side, but information other than the MAC address may be used.

  The device specifying unit 13 performs device name-collection information matching from a device dictionary stored in advance in the device dictionary database 14 to specify a home device, and registers the specified home device in the home device list. FIG. 2 shows an example of a home device list. In the home device list shown in the figure, the device name is associated with the MAC address, the state, and the authorized user.

  The device dictionary database 14 stores a device dictionary. FIG. 3 shows an example of a device dictionary. The device dictionary includes a device name, a specific information dictionary for specifying a home device, and a communication condition dictionary for generating a communication condition list to be described later. When the device specifying unit 13 specifies the device name of the home device based on the description in the specific information dictionary for the newly detected home device, the home device held by the user, that is, the communication condition dictionary of the specified home device, A communication condition list is generated based on the combination of the home device and the home device, and is transmitted to the restriction processing unit 15.

  The communication condition list is a list in which communication conditions are described for each home device detected in the user's home and for each combination of home devices detected. Conditions that match the combination of the home device and the home device are extracted from the communication condition dictionary of the device dictionary and listed. For communication conditions combined with home devices, communication conditions that need to be determined together with newly detected devices are extracted from the communication condition dictionary and added to the communication condition list. Since the detected combinations of home devices are finite, the list capacity can be reduced, the number of communication conditions described can be reduced, and processing for controlling communication can be executed at high speed. FIG. 4 shows an example of the communication condition list. The communication condition list shown in the figure describes communication conditions for each MAC address of the home device. In the communication condition, information such as whether the home device is a connection source or a connection destination, a use protocol, a processing content, and the like is described. A plurality of communication conditions may be described in one entry. There may also be an entry combining a plurality of home devices. The communication conditions include a start condition that describes the conditions before the start of usage restrictions on the home device, a communication condition that describes the conditions when the home device is being used, and an end condition that describes the conditions after using the home device. is there.

  Since the device dictionary is enormous, it is managed by the server of the business operator, and the communication control device 1 transmits information for specifying the home device to the server, and the server side efficiently performs batch processing. A communication condition list may be generated. In this case, the communication control apparatus 1 may receive and hold the communication condition list from the server, or may hold the communication condition list at the server. When the communication control device 1 downloads the communication condition list every time, it is desirable that the communication control device 1 can download the communication condition list from the time when the communication of the in-home device is detected until the start of use through authentication.

  The restriction processing unit 15 controls communication of household devices based on the communication condition list and the restriction rules stored in the restriction rule storage unit 16.

  The restriction rule accumulating unit 16 stores restriction rules that describe communication usage restrictions for each home device and each user. The restriction rule is set by an administrator who manages communication restrictions of home devices. Usually, the administrator is the same as the administrator of the gateway device incorporating the communication control device 1. FIG. 5 shows an example of the restriction rule. In the restriction rule shown in the figure, use restriction information is associated with a combination of a device name of a home device and a user. Usage restriction information includes usage restriction methods and usage records. Examples of usage restriction methods include a method of restricting communication by cumulative time, a method of restricting communication by providing a time limit every time, a method of restricting by a use time zone, and the like.

  Next, a processing flow of the communication control apparatus in the present embodiment will be described.

  FIG. 6 is a flowchart showing a flow of processing for detecting communication of a home device and starting use restriction.

  When the user starts using the home device, the communication control device 1 detects communication by the home device on the LAN side (step S11), and the device specifying unit 13 specifies the home device from the detected communication (step S12). In order to specify a home device, UPnP, SNMP OUI, and MAC address are used. If the specified home device is not registered in the home device list, the specified home device is registered in the home device list, and communication related to the home device listed in the home device list and the combination thereof is referred to the device dictionary. Create a communication condition list by listing conditions. Further, the administrator sets a restriction rule for each in-home device and for each user by processing to be described later.

  When the device identification unit 13 identifies a home device, the restriction processing unit 15 obtains the communication condition of the home device from the communication condition list and obtains the restriction rule set for the home device from the restriction rule storage unit 16. (Step S13). In addition, in the case of a home device with no restriction, communication is permitted without performing the following processing.

  Since some home devices cannot be used if communication is interrupted at the start of communication, the timer is set based on the authentication timer described in the start condition of the communication condition of the home device (step S14), and communication is performed even in an unauthenticated state. Allow time to allow.

  Then, the user is prompted to input authentication information to perform user authentication (step S15). If authentication is not performed before the time-out and if there is no remaining available time described in the restriction rules for each home device and each user (NO in step S15), the communication of the home device is blocked (step S20). If it is not necessary to identify the user, and there is a remaining available time of the home device, the process proceeds to step S16 to start counting the usage time. In addition, when the communication is interrupted in step S20, if the home device and the communication control device 1 are connected wirelessly (Wi-Fi or the like), the home device is switched to another wireless (3G or the like) when the wireless is blocked. Because there is a terminal to connect to, no wireless in the house is disconnected. Also, communication such as ARP and DHCP for permitting device name identification, device search, and communication itself is not blocked.

  If the authentication is successful and there is a remaining available time (YES in step S15), counting of the usage time of the home device is started (step S16). For example, when a time limit of 1 hour is set once, the queue is held at a position corresponding to the time limit of the timer queue, and it is determined that the time limit has expired at the timing when the queue is taken out. . If there is a limit on the accumulated time, the accumulated time of the restriction rule is updated. Note that the available time may be checked at the start of the timer or at the regular check, and if the remaining available time is small, it may be notified to a pre-registered and authenticated user. The administrator can acquire each usage time and remaining usage time.

  When the available time set in the restriction rule is exhausted (YES in step S17), the communication of the in-home device that has no available time is blocked (step S20).

  If a use stop is detected (Yes in step S18), use time counting is stopped (step S19). For example, if the end condition of the communication condition indicates that the home device transmits a FIN to a specific address when the use of the home device ends, the FIN transmitted from the home device to the specific address is It is determined that the use is stopped at the time of detection, and the use time count is stopped. Further, when it is described that there is regular communication in the communication condition of the communication condition, it is determined that the use is stopped when there is no regular communication from the home device. When the processing capacity of the communication control device 1 is ample, an end condition that compares the average bandwidth can also be applied. In addition, when the post-processing time after the suspension of use and the time during which communication must be continued are described in the end condition of the communication condition, the communication is cut off after that time elapses.

  Next, a restriction rule and a process for registering a user will be described.

  FIG. 7 is a flowchart showing a flow of processing for an administrator to register a restriction rule and a user. The administrator accesses the setting URL of the communication control device 1 and registers the restriction rule and the user. In the communication control device 1, an administrator password for accessing the setting URL is registered in advance.

  When the administrator connects to the setting URL of the communication control device 1, the newly detected home device is displayed and the setting for the home device is accepted (step S21). At this time, a list of all home devices described in the home device list may be displayed. A device that is currently connected to the home LAN is scanned by a Discover protocol such as ARP, and the home device is not discarded even if it is not connected, so that it is displayed together with the home device that has been set in the past. Examples of settings for home devices include owner settings for the home devices and authorized user settings.

  The administrator selects a home device and registers a restriction rule (step S22). Since it is assumed that a plurality of users use the home device, use restriction information is registered for each home device and each user. For example, in the example illustrated in FIG. 5, different usage restriction information is registered for each set of the device A and the user F and the device A and the user G. When restricting use without distinguishing between users, use restriction information is registered with the user as ALL, as in the device C of FIG. Although not shown in FIG. 5, use restrictions may be set for each protocol used by the home device, or use restrictions may be set for each application executed on the home device.

  If necessary, the administrator registers a new user (step S23). FIG. 8 shows an example of user information. In the user information shown in the figure, a user name or a user identifier, a PIN number, a PIN date issuance date and expiration date are registered. The communication control apparatus 1 uses a PIN number for user identification. By inputting the PIN number when the user uses the home device, the communication control device 1 identifies the user and counts the usage time.

  When a new PIN number is issued, the PIN number is notified to the corresponding user (step S24). When a user is registered, an online account such as an e-mail address may be registered, and a new PIN number may be transmitted to the account, or an administrator may notify the user verbally.

  Steps S22 to S24 can be repeatedly registered for the number of in-home devices and for the number of users.

  Next, an operation for processing a signal from a home device based on the communication condition list will be described.

  FIG. 9 is a flowchart showing a flow of processing a signal from the home device based on the communication condition list.

  When the signal transmission / reception unit 11 receives the signal, the signal extraction unit 12 extracts the MAC address from the signal, and determines whether or not it is the MAC address of the identified home device (step S31). It is determined whether or not the transmission source and transmission destination MAC addresses extracted from the signal have been registered and determined. The MAC address of the home device specified so that only the MAC address can be scanned is developed on the memory.

  When the home device is not specified (No in step S31), the device specifying unit 13 performs a process of specifying the home device (step S32).

  If the home device is specified (Yes in step S31), the extracted MAC address is searched from the communication condition list to determine whether the communication condition is set (step S33). When both the source and destination MAC addresses correspond, both communication conditions are referred to.

  If the MAC address is registered but there is no communication condition (No in step S33), the received signal is transmitted (step S34).

  Hereinafter, an example of the device A in the communication condition list illustrated in FIG. 4 will be described. In the example of the communication condition list in FIG. 4, two communication conditions are described in the device A.

  First, it is determined whether or not communication condition 1 is applicable (step S35). Communication condition 1 permits communication for 30 seconds when the corresponding MAC address is the transmission source and the protocol is https. When the communication condition 1 is applicable (Yes in step S35), the received signal is transmitted (step S36).

  If the communication condition 1 is not applicable (No in step S35), it is determined whether the communication condition 2 is applicable (step S37). Communication condition 2 is for user authentication when the corresponding MAC address is the transmission destination and the protocol is RTP. If user authentication fails (No in step S37), the received signal is discarded. If the user authentication is successful (Yes in step S37), processing based on the restriction rule is performed with the signal transmitted until the use restriction time.

  Next, examples of the present invention will be described.

  First, an example in which a home device is lent to another user will be described.

  When the user lends home equipment to another user, for example, when the brother lends home equipment to the younger brother, the brother can limit the use time of the younger brother. In this case as well, the communication usage restrictions (usage time zone, cumulative time, time restrictions) set by the administrator for the older brother cannot be exceeded. The communication usage restriction for another user can be set by the owner of the home device. The first user listed in the permitted user in the home device list is the owner of the home device. The owner accesses the URL for setting the communication control device 1, sets the communication use restriction of the home device for another user according to the authority of the owner, and the restriction rule storage unit separately from the restriction rule for each home device set by the administrator 16. FIG. 10 shows an example of owner setting information. In the example shown in the figure, the owner of the device A sets a time limit for the user G. The time limit set here cannot exceed the time limit of the device A set for the user G by the owner of the device A. Further, the time limit of the device A set by the administrator for the user G cannot be exceeded. Note that setting of communication usage restrictions for other users by the owner is not essential.

  Next, an embodiment in which communication is established by simultaneously connecting a plurality of home devices will be described.

  For example, in the case of a service established by simultaneously performing video communication on a television and data communication on a smartphone, it is necessary to count the usage time as communication time when the television and the smartphone are simultaneously connected.

  In this embodiment, the communication condition list is executed by describing a communication condition for counting the usage time when video communication and data communication are simultaneously performed. The combination of detected home devices is finite, and as a condition that matches this combination, a communication condition that the video signal and the data signal are counted together is extracted from the communication condition dictionary of the device dictionary and described in the communication condition list. . In the example of FIG. 4, the communication conditions describing both the device T and the device U correspond to this embodiment. An example of the communication condition in this case is that when a request for RTP communication is made for an IP prefix whose destination is the video MAC source and the transmission destination is the video MAC address, and for the IP prefix of the data acquisition server, an HTTP GET When a method is sent. An IP prefix is acquired from the device dictionary based on the device name, and RTP communication using the acquired IP prefix as a connection destination is described in the communication condition of the television. When this communication condition is met, a flag is set in the memory, and communication restriction is performed when an HTTP GET method with the IP prefix of the data acquisition server as the connection destination is transmitted. For example, in the example of a service that distributes a problem using a moving image and an answer using data, both viewing times can be limited. In addition, when only data communication is described in the communication condition, it is possible to limit the viewing time of only the answer.

  Next, an embodiment that specifies application communication and restricts the use will be described.

  Since the communication control device 1 according to the present embodiment can be limited by the traffic passing through the communication control device 1, when a plurality of applications such as a smartphone can be operated, the communication of the application is specified as a communication condition. Can be restricted. For example, in a smartphone, the telephone function is not restricted for use, but is restricted by specifying other applications. The device identifying unit 13 detects and identifies the communication of the application based on the connection destination, the session information, etc. at the timing of update, user information confirmation, etc. at the start of application communication.

  When restricting the use of application communication, the communication condition list includes a communication condition including the application name in the device name. By registering data that includes the application name in the device name in the device dictionary, the application name is included in the device name when creating a communication condition list from the device dictionary when a home device or application is detected. A communication condition is created. The administrator sets a restriction rule for each application as in the home appliance. The restriction processing unit 15 also controls application communication based on communication conditions in the communication condition list and restriction rules.

  When restricting the use for each application, if the application can be executed by a plurality of home devices such as smartphones and personal computers, the use time is limited by adding the use time of the application in each home device.

  Next, an embodiment in which one home device X is used across a plurality of communication control apparatuses 1A and 1B will be described.

  When the user A's home device X is registered in the user A's home communication control device 1A, when the user B's home device X is brought to another user B home and used, the user B home communication control device 1B When the use of the home device X is not restricted or when the administrator of the user B home is permitted, the home device X is added to the combination of the home devices of the user B home and the communication restriction of the home device X alone at the user B home is restricted. In addition to this, it is possible to perform communication restriction based on a combination with the user B's home device. When the home device X joins the home device of the user B home, a communication condition list including the home device X is created, and the home device X is registered in the communication control device 1B of the user B home. Further, since the home device X is already registered in the communication control device 1A, the communication control device 1B of the user B home does not set a new communication use restriction for the home device X, and the communication control device 1A of the user A home The restriction rule regarding the in-home device X can be acquired from the communication device, the accumulated use time is exchanged between the communication control devices 1A and 1B, and the use time can be restricted by adding up the use time of the user A home and the user B home. In addition, you may manage a restriction rule with a server and may add up the utilization time of in-home equipment X. When the owner of the home device X is changed from the user A to the user B, the registration of the home device X in the communication control device 1A is canceled.

  In addition, if you enable the logic to inquire the communication control device once when the use of the home device starts, the home device cannot be used if there is no inquiry to the communication control device, so restrict communication by other communication means such as other companies' mobile networks. Can do. Even if the “Wi-Fi connection prohibition” function of the home device is not enabled, both the communication restriction of the mobile business company and the communication restriction of the communication control device can be used by using the communication control device. By installing a communication control device in a mobile business company, communication using a mobile phone network can also be restricted.

  As described above, according to the present embodiment, the signal extraction unit 12 extracts the MAC address from the signal of the home device, the device specifying unit 13 specifies the home device, and the restriction processing unit 15 specifies the specified home Control the use of communication by identifying the home device by controlling the communication of the home device based on the communication condition list describing the communication conditions for each device and its combination and the use restriction information set for each device. Is possible. Further, by setting the use restriction information for each user, it is possible to restrict the use of communication for each user even when a plurality of users use the same in-home device.

  According to the present embodiment, the owner of the home device sets the use restriction for other users within the use restriction range set for the owner, so that it is within the scope of the authority of the user other than the administrator. It is possible to flexibly limit the communication of home devices.

  According to the present embodiment, communication for authentication can be performed without detecting the communication content of the home device by providing a time for allowing communication even in an unauthenticated state based on the authentication timer of the communication condition start condition. Can be allowed.

  According to the present embodiment, application communication can be controlled by describing application information in the device dictionary, describing application entries in the communication condition list, and setting usage restrictions for each application.
