There is also. Under such circumstances, various services in which these devices communicate with servers and other devices (any device that participates in a network including a PC) deployed in the same local network are being studied.

  These devices (black appliances, white appliances, etc.) are controlled from an external server different from the local network or provide information via the Internet network, 3G network, LTE network, WiMAX network, etc. Realization of services using external servers and black goods is also being considered.

  First, an outline of an embodiment will be described with reference to FIG. Note that the reference numerals of the drawings attached to the outline are attached to the respective elements for convenience as an example for facilitating understanding, and the description of the outline is not intended to be any limitation.

  As described above, for a consumer user who is not sufficiently familiar with the handling of network equipment, the work for joining an M2M device to the network is an extremely complicated work. Therefore, a device identifier setting device that automatically acquires a device identifier necessary for joining an M2M device to a network is desired.

  Therefore, the device identifier setting apparatus 100 shown in FIG. 1 is provided as an example. The device identifier setting apparatus 100 analyzes identifiers obtained from a radio wave analyzer that can acquire bit string information including communication information between the first device and the second device from radio waves emitted by the first device. Information that is held by the unit 101 and the second device, and that determines whether to relay communication from the first device from the first network including the first device to the second network And an identifier determination unit 103 that determines whether or not to set the device identifier of the third device obtained from the analysis result of the identifier analysis unit 101 in the connection permission information. Furthermore, the identifier setting unit 102 sets, in the connection permission information, the device identifier of the third device that has been determined to be set in the connection permission information.

  The device identifier setting apparatus 100 acquires bit string information from the radio wave transmitted by the third device from the radio wave analysis apparatus, and acquires the device identifier of the third device by analyzing the acquired bit string information. Furthermore, the device identifier setting apparatus 100 determines whether or not the acquired device identifier should be set in the second device. As a result of the determination, the device identifier determined to be set is set in the connection permission information held by the second device. As a result, there is substantially no work required for the user, and the device identifier setting apparatus 100 corresponding to the gateway should obtain an appropriate device identifier to be automatically set and set for the second device. A valid device identifier can be set.

  First, a network including an M2M device and a method for joining the M2M device to the network will be described. At that time, a service realized using an M2M device (communication equipment; node) scheduled to participate in a network, such as a sensor device, an actuator device, a black appliance, a white appliance, or the like, is referred to as an “M2M service”.

  When the M2M device communicates with other M2M devices, servers, PCs, etc. in the local network, or when the M2M device communicates with an external server via the Internet network or the like, these devices (M2M devices) , Server, PC) becomes a problem.

  M2M devices have limitations on functions that can be realized for reasons of device specifications, compared to servers and PCs. Therefore, it is difficult to provide the capability to realize communication with other M2M devices, servers, and PCs. For example, in order for a sensor device that performs communication using the ZigBee (registered trademark, hereinafter the same) protocol to communicate with a server or a PC that supports TCP / IP (Transmission Control Protocol / Internet Protocol), these sensor devices must be TCP / IP. It is necessary to provide an IP stack. However, it is difficult to realize communication by TCP / IP from the performance side of these sensor devices.

  Furthermore, in order for an air conditioner (white goods) equipped with a TCP / IP stack to communicate with a TV (black goods) and display the room temperature information of the air conditioner on the TV, the air conditioner information is displayed on the TV. It is necessary to incorporate the function to acquire, and the cost of the television rises. As described above, it is difficult for the M2M device to directly communicate with other M2M devices, servers, PCs, and the like due to specifications (performance) and cost restrictions, which hinders the spread of M2M services.

  In order to realize the M2M service, there is an architecture in which a gateway (HGW: HomeGW, BGW: BuildingGW, etc.) relays communication between the M2M device and other M2M devices, servers, and PCs. In such an architecture, the M2M device communicates directly with the gateway. The gateway communicates with other M2M devices, servers, and PCs, thereby realizing communication between the M2M devices and other M2M devices, servers, and PCs. For example, assume that a sensor device that handles temperature / humidity information transmits temperature / humidity sensor information to the gateway using the ZigBee protocol. Thereafter, the gateway transmits the obtained temperature / humidity sensor information to the server by TCP / IP. In this way, communication between a sensor device (using ZigBee protocol) and a server (using TCP / IP) that cannot communicate directly with each other is realized. The gateway may be a so-called broadband router, or may exist as an independent device separate from the broadband router in order to provide an M2M service.

  An M2M device that performs short-range wireless communication such as a specific low-power radio station device or a ZigBee device requires a controller (ZC: ZigBee Coordinator in the ZigBee device) for connection to the gateway. A controller serving as a parent of a PAN (Private Area Networks) configured by a specific low-power radio station, a ZigBee device, or the like connects to the network. Thereafter, the sensor device (ZR: ZigBee Router or ZED: ZigBee End Device in the ZigBee device) that transmits various types of observation information notifies the gateway of the observation information via the controller of the PAN to which the sensor device belongs. In the following description, a communication device (node) that manages the PAN to which it belongs and controls the interconnection with the gateway is referred to as “M2M controller”. The M2M controller performs management and control related to connection of an M2M device (child M2M device) that is a child of a PAN (own network) developed by the M2M controller itself. In particular, appropriate management and control is necessary for the connection of the child M2M device to its own network.

  The M2M controller excludes connection of an inappropriate child M2M device by the M2M controller itself holding and storing connection permission information in which device identifiers of child M2M devices that are permitted to be connected are collected. Note that the identification information used at that time may be information such as a MAC (Media Access Control) address that can uniquely identify a device. In this document, such a connection method is referred to as a restricted connection method, and the following description will be given.

  In the restricted connection method, when receiving a connection request notification or data communication issued by a child M2M device, the M2M controller permits communication from the M2M device existing in the connection permission information or accepts data. However, for communication from an M2M device that does not exist in the connection permission information, connection is not permitted or data is discarded. The connection of the M2M device by the restricted connection method has a problem in that the usability is lowered in the realization of the M2M service.

  In order to realize the connection of the child M2M device, the user needs to set the device identifier of the M2M device participating in the M2M service in the M2M controller. By correctly setting the device identifier of the M2M device in the M2M controller, a valid M2M device desired by the user can be connected to the network. However, operations such as confirmation of device identifiers described in manuals such as the device main body of device identifiers, operation manuals or device setting documents, and setting of device identifiers in the M2M controller after confirmation are performed by ordinary users. (Consumer user) is a complicated task.

  For such a user, such work is difficult to understand, and also causes troubles due to erroneous operations (such as setting an incorrect device identifier). Such an operation causes a decrease in usability in the realization of the M2M service. Therefore, a technique for realizing M2M service while ensuring high usability is required. For example, the development of an automatic device identifier setting method in which a gateway automatically sets a device identifier of a legitimate M2M device attempting to connect to a network deployed by the M2M controller to the M2M controller in a manner that minimizes the work of the user. I need it.

  The gateway to which the M2M controller is connected often has a function of creating, deleting, and updating the connection permission information of the M2M controller. If the gateway can automatically obtain a valid device identifier, such a M2M device can be used. Can be connected automatically. However, in the restricted connection method, the above-mentioned automatic device identifier setting method cannot be realized because the gateway cannot automatically obtain a valid device identifier that should be permitted to connect.

  The legitimate device identifier is described in the device body of the device identifier, and the device identifier read operation (confirmation operation) by the user is performed in order to obtain the device identifier that the gateway should set in the M2M controller. It is necessary to input the device identifier to the gateway. These device identifier confirmation work and device identifier input / setting work to the gateway are factors that cause a decrease in usability, and are contrary to the purpose of the automatic device identifier setting method, and therefore cannot be accepted as processing of the automatic device identifier setting method. In other words, an existing gateway cannot set a valid device identifier in the M2M controller without such user operations, and thus cannot implement an automatic device identifier setting method. In order to realize the automatic device identifier setting method, it is necessary to obtain a legitimate device identifier that the gateway should automatically permit to connect without any user operations or with as few user operations as possible.

  Here, there is a device called a radio wave analysis device that obtains radio waves flying in space and extracts radio wave information. A radio wave analyzer called a packet analyzer or sniffer obtains radio waves in the corresponding frequency band from the radio waves that fly in an effective space, and also uses radio wave information (communication information) at least in the physical layer using the corresponding demodulation method. Can be extracted. The extracted radio wave information is information obtained by converting radio waves as analog information into a lump of digital information (bit string information) by a corresponding demodulation method or the like. Therefore, the radio wave analysis device can acquire bit string information of a packet transmitted by an arbitrary sender. Such bit string information is packet information of the physical layer in the communication protocol adopted by the sender, and various pieces of communication information can be acquired by appropriately analyzing the bit string information at the physical layer or higher.

  In addition, the radio wave analysis apparatus has not only a function for acquiring bit string information but also a function for performing appropriate analysis in the physical layer or higher, as well as a function for acquiring bit string information of the physical layer. There are also cases where the appropriate analysis described above is entrusted or requested to an external device.

  Hereinafter, specific embodiments will be described in more detail with reference to the drawings.

[First Embodiment]
The first embodiment will be described in more detail with reference to the drawings.

  FIG. 2 is a diagram showing an example of a network system configuration including the device identifier setting device 1 according to the present embodiment.

  In the system shown in FIG. 2, a restricted connection method using connection permission information in the M2M controller is adopted. In the following drawings including FIG. 2, broken arrows indicate control between each component, reference, transmission of information, and the like.

  The system of FIG. 2 includes a device identifier setting device 1, an M2M device 2, an M2M controller 3, and a radio wave analysis device 4.

  The M2M device 2 is a device in which radio waves are analyzed by the radio wave analysis device 4 and the presence is extracted when performing communication for attempting to connect to an unspecified M2M controller. That is, the M2M device 2 at the stage where the presence is extracted corresponds to the first device described above.

  The device identifier setting device 1 acquires bit string information of communication between the M2M device and the M2M controller, and acquires the device identifier of the M2M device by analyzing the acquired bit string information. The device identifier setting device 1 sets the acquired device identifier in the M2M controller 3 (corresponding to the second device described above) connected to the own device. The device identifier setting device 1 corresponds to one configuration of the gateway described above. In other words, the device identifier setting device 1 is information held by the first network including the M2M device and the M2M controller 3 included in the first network and relaying communication from the M2M device to the second network. It is possible to set connection permission information that determines whether or not to relay the M2M device to the second network. Here, the M2M device 2 determined to be set in the connection permission information held by the M2M controller 3 corresponds to the above-described third device.

  The device identifier is similar to device identification information generated from a MAC address, network address, device serial number, other device information, and the like, and is information that uniquely identifies the device. Various device identifiers are conceivable for each M2M device and for each protocol adopted by the M2M device. Further, various lengths (bit string information lengths) of the device identifier represented by a single numerical sequence can be assumed, but the type and form of the device identifier are not particularly limited.

  Next, communication in which the M2M device 2 tries to connect to an unspecified M2M controller in the restricted connection method will be described. At this time, the device identifier setting device 1 sets the device identifier of the M2M device 2 to the M2M controller 3 connected to its own device (device identifier setting device 1) based on the bit string information obtained from the radio wave analysis device 4. An overview is also described.

  In FIG. 2, the device identifier setting device 1 is in communication with the radio wave analysis device 4 and the M2M controller 3 (connected in advance).

  The M2M device 2 transmits a packet 200 (radio signal) at an arbitrary timing determined by the M2M device 2 itself, for example, when the user turns on the power of the M2M device 2. The packet 200 transmitted by the M2M device 2 may be a connection request signal for some M2M controller that can accommodate the M2M device 2 itself, or may be a data signal for some M2M controller that can communicate with itself. . In any case, the M2M device 2 transmits the packet 200 in order to properly receive and accept the communication by the packet 200 by an unspecified but valid M2M controller.

  Note that the packet 200 is communication that does not specify a destination (so-called broadcast transmission), and “FF: FF: FF: FF: FF: FF: FF: FF” indicating a broadcast address is designated as the destination ID. Further, “01: 23: 45: 67: 89: AB: CD: EF” which is the device identifier of the M2M device 2 is designated as the transmission source ID.

  The M2M device 2 continues to transmit the packet 200 until it can be connected to any M2M controller or until it can be determined that the transmitted packet 200 has been accepted by a valid M2M controller.

  The M2M controller 3 determines from the received packet 200 that the communication is from a device having a device identifier (source ID) of “01: 23: 45: 67: 89: AB: CD: EF”. However, in this case, since this device identifier is not set from the device identifier setting device 1 and communication is from an M2M device that does not exist in the connection permission information of the M2M controller 3 itself, such communication is discarded, and the M2M device 2 Does not accept signals sent by.

  The radio wave analysis device 4 acquires the radio wave transmitted by the M2M device 2 and performs radio wave analysis to extract the bit string information 201 of the digital information described in the packet 200 from the analog information. The radio wave analysis device 4 notifies the extracted bit string information 201 to the device identifier setting device 1.

  The device identifier setting device 1 analyzes the bit string information 201 obtained from the radio wave analysis device 4, and sets the transmission source ID “01: 23: 45: 67: 89: AB: CD: EF” included in the bit string information 201 as the device. Get as an identifier. When the device identifier setting device 1 determines that the acquired device identifier is the setting ID 202 to be set in the M2M controller 3, the device identifier setting device 1 sets the setting ID 202 in the M2M controller 3.

  The M2M controller 3 receives the setting of the setting ID 202 by the device identifier setting device 1 and sets “01: 23: 45: 67: 89: AB: CD: EF” in its connection permission information as a device identifier that permits connection. sign up. As a result, when the packet 200 transmitted by the M2M device 2 is received, communication from the device having the transmission source ID “01: 23: 45: 67: 89: AB: CD: EF” included in the packet 200 is performed. Can be allowed. That is, the M2M controller 3 accepts communication from the M2M device 2.

  Next, the configuration and operation of the device identifier setting device 1 will be described. FIG. 3 is a diagram illustrating an example of an internal configuration of the device identifier setting device 1.

  As described above, the device identifier setting device 1 acquires the device identifier by analyzing the bit string information obtained from the radio wave analysis device 4. The device identifier setting device 1 determines whether or not the acquired device identifier should be set in the M2M controller 3 connected to the device itself, and if it is determined to set, the device ID setting device 1 sets the setting ID (acquired device identifier). Set to M2M controller 3.

  The device identifier setting device 1 includes at least an identifier analysis unit 10, an identifier determination unit 20, an identifier setting unit 30, and a device management unit 40.

  The identifier analysis unit 10 acquires a device identifier by analyzing the bit string information. The identifier determination unit 20 determines whether or not the acquired device identifier should be set in the M2M controller 3 of the own device. The identifier setting unit 30 sets a device identifier to be set in the valid M2M controller 3. The device management unit 40 manages information related to the M2M controller 3 and the M2M device 2.

  The identifier analysis unit 10 receives the bit string information from the radio wave analysis device 4 and appropriately analyzes the obtained bit string information, thereby trying to connect to some M2M controller from the bit string information or transmitting data to some M2M controller. The device identifier of the M2M device 2 is acquired. The identifier analysis unit 10 appropriately analyzes not only the bit string information related to the communication of the M2M device 2 but also all other bit string information received from the radio wave analysis device 4, so that not only the device identifier of the M2M device 2 but also the destination device Device identifier, protocol control information, and other information related to the M2M device.

  Furthermore, the identifier analysis unit 10 can also obtain the radio wave intensity of the radio wave of the bit string information analyzed by the radio wave analysis device 4 from the radio wave analysis device 4. The identifier analysis unit 10 notifies the identifier determination unit 20 of the acquired information.

  The identifier analysis unit 10 includes at least an identifier analysis function selection unit 11 and an analysis module group 12.

  The identifier analysis function selection unit 11 specifies an analysis module (module that executes ID analysis) for appropriately analyzing the bit string information obtained from the radio wave analysis device 4, and analyzes the bit string information for the specified analysis module. Request (instruct). Alternatively, when an appropriate analysis module cannot be identified, the identifier analysis function selection unit 11 may request analysis of bit string information from all analysis modules that may request analysis.

  The identifier analysis function selection unit 11 connects the management information (device management information) of the M2M controller 3 and the M2M device 2 connected to the device identifier setting device 1 from the device management unit 40 or specifying the analysis module. get. Based on the acquired device management information, the identifier analysis function selection unit 11 determines the type, manufacturing vendor, and the like of the connected M2M controller 3 and M2M device 2. The identifier analysis function selection unit 11 specifies an analysis module capable of analyzing bit string information handled by the connected M2M controller 3 and the M2M device 2 based on the type of the M2M device and the manufacturing vendor.

  Furthermore, the identifier analysis function selection unit 11 requests the specified analysis module to analyze the bit string information, thereby acquiring the analysis result including the device identifier of the transmission source device. The analysis module to be specified may be singular or plural. Note that the types of the M2M controller 3 and the M2M device 2 may be a ZigBee device, a Z-Wave (registered trademark, hereinafter the same) device, a Bluetooth (registered trademark, the same hereinafter) device, a specific low-power radio station device, or the like.

  The analysis result acquired by the identifier analysis function selection unit 11 includes a device identifier of the transmission source device, a device identifier of the destination device, protocol control information, and other information related to the M2M device.

  The identifier analysis function selection unit 11 includes, in addition to the analysis result information acquired from the analysis module, the time when the bit string information is acquired from the radio wave analysis device 4, the radio wave intensity of the radio wave corresponding to the acquired bit string information, and the M2M controller to be set Information relating to the identifier determination unit 20 is notified. The information related to the M2M controller includes protocol information, vendor information, device information for identifying the controller, and the like. Information regarding the M2M controller to be set is determined from device management information obtained from the device management unit 40.

  The analysis module group 12 is a collection of analysis modules that analyze bit string information. Each analysis module is prepared for each protocol such as ZigBee, Zwave, Bluetooth, IEEE (The Institute of Electrical and Electronics Engineers, Inc.) 802.11, IEEE 802.15.4, and the like. Alternatively, it is prepared for each vendor (A company device, B company device, etc.) and for each device (A company ZigBee device No_1, B company specific low power radio station device No_2, etc.). The analysis module may be arranged inside the device identifier setting device 1 as the analysis module group 12, but may be a function of a server existing outside the device identifier setting device 1.

  The analysis module included in the analysis module group 12 and requested to be analyzed by the identifier analysis function selection unit 11 analyzes the obtained bit string information using its own analysis target packet format. As an example of the analysis method using the packet format, there is a method of extracting information that matches the packet format from the beginning of the bit string information.

  As a result of the analysis, the analysis module extracts the device identifier of the transmission source device, the device identifier of the destination device, protocol control information, and other M2M device information, and notifies the identifier analysis function selection unit 11 of the extracted information.

  In the analysis module requested to be analyzed by the identifier analysis function selection unit 11, the analysis of the bit string information may not be correctly performed. In such a case, the analysis module notifies the identifier analysis function selection unit 11 of an error or does not notify the analysis information or the error information.

  The determination as to whether or not the analysis module has been correctly analyzed differs depending on the analysis method using the packet format. For example, it can be understood that the analysis is abnormal by finding the appearance of bit string information that does not conform to the packet format, or inconsistencies between a plurality of pieces of packet information extracted from the bit string information (such as combinations that cannot be handled as protocols or devices). .

  Whether the identifier determination unit 20 should connect the device identifier of the transmission source device obtained from the identifier analysis unit 10 to the M2M controller 3 connected to the device identifier setting device 1 or to communicate with the M2M controller 3 Judging. That is, it is determined whether or not the transmission source device is an M2M device that the user using the device identifier setting device 1 desires to connect to. The analysis result of the identifier analysis unit 10 is used in the determination.

  In the analysis result of the identifier analysis unit 10, the device identifier of the transmission source device, the device identifier of the destination device, protocol control information, other M2M device information, and the device identifier setting device 1 obtained the bit string information from the radio wave analysis device 4. Time, radio wave intensity, information on the M2M controller to be set, and the like are included.

  When the identifier determination unit 20 determines that the device identifier of the transmission source device included in the obtained analysis information should be set in the connection permission information held by the M2M controller 3 of the device identifier setting device 1, the identifier determination unit 20 On the other hand, it requests the setting of the acquired device identifier and notifies the analysis information.

  The identifier determining unit 20 includes at least a neighboring device specifying unit 21.

  FIG. 12 is a diagram illustrating an example of an internal configuration of the device identifier setting device 6 according to the present embodiment. 12, the same components as those in FIG. 11 are denoted by the same reference numerals, and the description thereof is omitted.

  The device identifier setting device 6 according to the present embodiment sets the device identifier acquired by utilizing the information of the device identifier assignment management server 7 that manages the assignment of external device identifiers to a valid M2M controller connected to the own device. . The device identifier setting device 6 includes an identifier determination unit 20a included in the device identifier setting device 1d.

  The device identifier setting device 6 determines whether or not the acquired device identifier is to be set in the M2M controller 3 connected to the own device, and uses the information of the device identifier assignment management server 7 when determining that the device identifier should be set. Then, the acquired device identifier is set in a valid M2M controller 3 connected to the own device.

  In the identifier setting unit 30a, the information of the device identifier assignment management server 7 is used for the determination of the appropriate M2M controller 3 in addition to the information included in the analysis information obtained from the identifier determination unit 20a.

  When the setting module cannot be specified from the analysis information obtained from the identifier determination unit 20a, the identifier setting function selection unit 31b specifies the setting module by inquiring the device identifier allocation management server 7 about the device identifier allocation status.

  The device identifier allocation management server 7 is a server that manages the allocation status of devices such as MAC addresses allocated by IEEE and IDs that uniquely identify devices. For example, information indicating which vendor (or range) of device identifiers is assigned is stored.

  The identifier setting function selection unit 31b uses the device identifier information of the transmission source device in the obtained analysis information to inquire the device identifier allocation management server 7 about the allocation status, and to which vendor the acquired device identifier is allocated. Judgment is made. Alternatively, the identifier setting function selection unit 31b assigns the acquired device identifier to which vendor, which type (protocol, series, etc.), or specifically which product, in response to an inquiry to the device identifier assignment management server 7. You can judge whether or not.

  The identifier setting function selection unit 31b adds the device identifier of the destination device in the analysis information, the device identifier of the M2M controller 3 that can be obtained from the device management unit 40, or the connection permission information in the M2M controller 3 as necessary. The device identifier assignment management server 7 can be inquired about the assignment status regarding the included device identifier.

  When the setting module can be specified from the analysis information, the identifier setting function selection unit 31b specifies the setting module from the analysis information. Further, the identifier setting function selection unit 31b notifies the setting device information utilization unit 51 of the identifier determination unit 20a of the device management information of the setting completion device after the setting of the device identifier in the requested analysis module is completed as necessary. .

  Next, the operation of the device identifier setting device 6 will be described.

  FIG. 13 is a flowchart showing an example of the operation of the device identifier setting device 6. Of the operations of the device identifier setting device 6 shown in FIG. 13, steps S20 to S27 are the same as the operations (steps S10 to S17) described with reference to FIG.

  In step S28, the identifier setting function selection unit 31b can specify the setting module that requests setting of the device identifier of the transmission source device in the analysis information from the information included in the analysis information specified by the identifier determination unit 20a. Determine whether. If it can be identified (step S28, Yes branch), the process proceeds to step S29. If it cannot be specified (step S28, No branch), the process proceeds to step S30.

  In step S29, the identifier setting function selecting unit 31b specifies a setting module that requests setting of the device identifier of the transmission source device in the analysis information from the information included in the specified analysis information, and sets the device to the specified setting module. Notify the identifier.

  In step S30, the identifier setting function selection unit 31b inquires about how the device identifier included in the analysis information is allocated to the device identifier allocation management server 7, thereby obtaining information on the acquired device identifier (vendor, which Such a type of product (protocol, series, etc., specific product name, etc.) is obtained, and a setting module that requests setting of the device identifier of the transmission source device in the analysis information is specified from the obtained information. Further, the device identifier is notified to the specified setting module.

  In step S31, using the setting module, the device identifier notified in step S29 or step S30 is set in the M2M controller 3 connected to the own apparatus.

  As described above, when the setting module for setting the device identifier cannot be specified from the analysis information alone, the acquired device identifier is obtained by using the information of the device identifier assignment management server 7 that manages the assignment of the external device identifier. It can be set to a valid M2M controller connected to its own device.
