Further, the WAN side of the gateway devices 1 and 2 is connected to an IP telephone network as an external network, and the gateway devices 1 and 2 are assigned an external telephone number as a global ID from the IP telephone network. The gateway devices 1 and 2 are connected to the community management server 3 through the WAN side IP telephone network.

  The gateway devices 1 and 2 communicate with home devices and have a role of converting each communication protocol of the devices into the SIP protocol. The gateway device 1 shown in the figure is installed at α house, and the external telephone number paid out from the IP telephone network is “046-1” (here, the telephone number is simplified). . The gateway device 1 includes an extension SIP server unit 11 (transmission unit, reception unit, communication unit), a virtual SIP terminal 12, a virtual SIP terminal function unit 13, a device communication function unit 14, and a device information storage unit 15. Have.

  The device communication function unit 14 exists for each of a plurality of communication protocols (communication types) such as UPnP, home wireless standards ZigBee, ECHONET, and Bluetooth. Each device communication function unit 14 communicates with a device having a corresponding communication protocol, and converts these communication protocols into SIP. In addition, the device communication function unit 14 notifies the virtual SIP terminal function unit 13 of the content of communication with the device.

  Each time the device communication function unit 14 discovers a new device, the virtual SIP terminal function unit 13 generates a virtual SIP terminal 12 using the communication content at the time of discovery. It is assumed that the virtual SIP terminal function unit 13 holds in advance definition information as to what kind of virtual SIP terminal the device discovered by the device communication function unit 14 is regarded as based on the communication content.

  There are N virtual SIP terminals 12 generated by the virtual SIP terminal function unit 13 for each device. In principle, it exists for each device, but it is not necessarily 1: 1. That is, one device may be a plurality of virtual SIP terminals, and vice versa. As a specific example, two types of virtual SIP terminals 12 of “printing” and “acquisition of remaining ink” may be used for one UPnP printer. One virtual SIP terminal 12 may be used for “obtaining remaining ink levels of all printers”. In the illustrated gateway apparatus 1, a virtual SIP terminal 12 for device B that uses a communication protocol other than the SIP protocol is generated.

  The extension SIP server unit 11 pays out an extension telephone number as a local ID to the SIP terminal and the virtual SIP terminal 12. A SIP terminal A, a device B, and a smartphone are connected to the gateway device 1 shown in the figure. The extension SIP server unit 11 pays out the extension telephone number 10 for the SIP terminal A and the extension telephone number 30 for the smartphone. Further, the extension SIP server unit 11 pays out the extension telephone number 20 to the virtual SIP terminal 12 generated corresponding to the device B to the device B.

  The device information storage unit 15 stores information regarding each device connected to the gateway device 1. FIG. 2A is an example of the device information storage unit 15 held by the gateway device 1. In the device information storage unit 15 shown in the figure, for each device, the assigned extension telephone number, communication protocol, device-specific ID, community ID and destination address of the community management server 3 to which the device belongs are stored. Are stored in association with each other.

The virtual SIP terminal function unit 23 is notified. The virtual SIP terminal function unit 23 generates a virtual SIP terminal 22 for the device C using the communication content with the device C notified from the device communication function unit 24. The extension SIP server unit 21 pays out the extension telephone number 20 to the virtual SIP terminal 22 generated corresponding to the device C.

  FIG. 2B is an example of a device information storage unit 25 held by the gateway device 2, and is an extension telephone number of the device C, a communication protocol, a device-specific ID, and a community management server to which the device belongs. Are stored in association with each other.

  In this embodiment, an IP telephone network is used as the external network, an external telephone number is used as the global ID, and an internal telephone number is used as the local ID. However, the present invention is not limited to these. For example, when an IP network is used as the external network, a global IP address may be used as the global ID, and a local IP address may be used as the local ID.

  Each community management server 3 is a server that manages a community (group) of a plurality of home devices, and exists for each community. As an implementation, a plurality of community management servers 3 may be virtually constructed on one physical server. Specifically, the community management server 3 exists for each community gathered for a certain purpose, such as “A elementary school school district”, “B town neighborhood association”, “C corporation”, “D family relative”, etc. To manage information on SIP terminals (including virtual SIP terminals).

  FIG. 3 is a block diagram showing the configuration of the community management server 3. The illustrated community management server 3 includes a member ID management unit 31, an authentication unit 32, a destination resolution unit 33, a member information provision unit 34, and a member information storage unit 35. The member ID management unit 31 pays out an in-community member ID (hereinafter referred to as “member ID”) to a SIP terminal (including a virtual SIP terminal) managed by itself.

  The authentication unit 32 receives the destination resolution request including the member ID of the communication destination device, and the external telephone number and the extension telephone number of the communication source device of the destination resolution request (or the external telephone number held by the device itself). Is stored in the member information storage unit 35, whether or not the communication source device is a device belonging to the community of the community management server 3 is authenticated.

  When the authentication is successful, the address resolution unit 33 acquires the external telephone number and the internal telephone number corresponding to the member ID (or the external telephone number held by the device itself) from the member information storage unit 35, and the member ID Resolve the destination. The member information providing unit 34 provides information regarding each member stored in the member information storage unit 35 to the device. In the member information storage unit 35, for each member ID issued by the member ID management unit 31, a corresponding external telephone number (global ID) and an internal telephone number (local ID) are stored in association with each other.

  FIG. 4 is an example of member information stored in the member information storage unit 35. In the member information shown in the figure, the member ID of each device in the group managed by the community management server 3, the external telephone number, and the internal telephone number (if the apparatus has its own external telephone number, the external telephone number is also included) And additional information such as a nickname are stored in association with each other. FIG. 4A shows member information stored in the member information storage unit 35 of the community management server A shown in FIG. FIG. 4B shows member information stored in the member information storage unit 35 of the community management server B shown in FIG.

  The gateway devices 1 and 2 and the community management server 3 described above use, for example, a general-purpose computer system including a CPU, a memory, an external storage device such as an HDD, an input device, and an output device. Can do. In this computer system, each function of each device is realized by the CPU executing a predetermined program loaded on the memory. For example, the functions of the gateway devices 1 and 2 and the community management server 3 are the CPU of the gateway devices 1 and 2 in the case of a program for the gateway devices 1 and 2 and the community in the case of a program for the community management server 3. This is realized by the execution of each CPU of the management server 3. The programs for the gateway devices 1 and 2 and the program for the community management server 3 can be stored in a computer-readable recording medium such as a hard disk, a flexible disk, a CD-ROM, an MO, or a DVD-ROM. It can also be distributed via.

  Next, the operation of this embodiment will be described.

  FIG. 5 is a sequence diagram showing a first operation example of the present embodiment. In the first operation example, a sequence is used when communication is performed from a device in one home belonging to the same community to a device in another home. Here, in the system shown in FIG. 1, the SIP terminal A (extension 10) of the α home (gateway device 1) belonging to the community management server A is the device C belonging to the same community management server A of the β home (gateway device 2). A case where communication is made to (extension 20) will be described as an example.

  It is assumed that member information shown in FIG. 4A is stored in advance in the member information storage unit 35 of the community management server A. The device information storage unit 15 of the gateway device 1 stores the device information of FIG. 2A, and the device information storage unit 25 of the gateway device 2 stores the device information of FIG. 2B. And

  Step 11: The SIP terminal A connected to the gateway device 1 accesses the community management server A by the browser function, and acquires information about the members from the community management server A. The member information providing unit 34 of the community management server A has its own community ID (= 12345) stored in a storage unit (not shown), each member ID in the community stored in the member information storage unit 35, and the user Additional information (such as a pre-registered nickname and model name) necessary for selecting “” is transmitted to the SIP terminal A. The SIP terminal A displays the acquired information on the browser (display). The community management server A does not transmit (disclose) the external telephone number #extension telephone number (destination) stored in the member information storage unit 35 to the SIP terminal A and does not display it on the browser of the SIP terminal A.

  The user selects a member ID of a device to be communicated using the browser function of the SIP terminal A. Here, it is assumed that the user selects the member ID = 0003 (β home device C: living printer) of the community management server A. The SIP terminal A receives a user operation, and transmits a communication request including the selected member ID to the community management server A.

  Step 12: When the community management server A receives the communication request from the SIP terminal A, the community management server A activates the telephone application of the SIP terminal A using a telto tag or the like to make a call. Thereby, the SIP terminal A requests the extension SIP server unit 11 of the gateway device 1 for SIP communication to “the device selected from the SIP terminal A”. At that time, a predetermined number (00 in the illustrated example) representing the extension SIP server unit 11 itself is used as the destination, and the community ID (= 12345) of the community management server A and the selected member ID within the community are used as subaddresses. (= 0003) is added to the destination in a specific format (00 # 12345 # 0003 in the illustrated example).

  In the process of step 11, the community ID, each member ID in the community, additional information, and the like may be notified to the user in advance by offline exchange such as telephone and mail. In this case, the member ID selected by the user is input to the SIP terminal A using the information notified in advance offline, and the SIP communication request is transmitted to the extension SIP server unit 11.

  Step 13: The extension SIP server unit 11 waits for the SIP communication request when a subaddress is added to the destination of the SIP communication request in a specific format. Then, the extension SIP server unit 11 refers to the device information storage unit 15, acquires the address of the community management server corresponding to the community ID specified as the destination (subaddress) of the SIP communication request, and sends the address to the acquired address. Sends a destination inquiry request for the member ID specified by the sub address.

  That is, the extension SIP server unit 11 refers to the device information storage unit 15 (FIG. 3A), and specifies the community ID (= 12345) specified in the community ID corresponding to the source SIP terminal A (extension 10). ) To obtain the address higashi.com (address of community management server A). Then, the extension SIP server unit 11 transmits a destination inquiry request for the specified member ID (example: ID = 0003) to the community management server A using the address. At that time, the extension SIP server unit 11 notifies the community management server A of the outside telephone number and extension number (046-1 # 10) of the SIP terminal A that is the call originator.

  Step 14: The authentication unit 32 of the community management server A determines whether or not the notified external telephone number and the equipment having the extension telephone number are members belonging to its own community. That is, the community management server A determines whether or not the notified set of external telephone number and extension telephone number exists in the member information storage unit 35.

  Step 15: If it is determined that the authentication unit 32 is a member, the destination resolution unit 33 sets the external telephone number and extension telephone number corresponding to the member ID (= 0003) specified in the destination inquiry request in Step 13 ( 046-2 # 20) is returned to the extension SIP server unit 11.

  Step 16: The extension SIP server unit 11 transfers the SIP communication request waiting in Step 13 to the destination returned in Step 15. At that time, the extension SIP server unit 11 adds a community ID in a predetermined format as a subaddress to the returned destination (046-2 # 20 # 12345 in the illustrated example). Thus, the existing line authentication is performed by the IP telephone network, and the telephone from the SIP terminal A is transferred to the extension SIP server unit 21 of the gateway device 2.

  Step 17: The extension SIP server unit 21 of the transfer destination gateway device 2 waits for the SIP communication request when a subaddress is added in a specific format to the received SIP communication request. Then, the extension SIP server unit 21 inquires of the community management server A about the set of the sender's external telephone number and extension telephone number and the set of the destination's external telephone number and extension telephone number.

  Step 18: The authentication unit 32 of the community management server A determines whether or not the source device and the destination device are members belonging to its own community, and sends the determination result (OK or NG) to the extension SIP server unit 21. Return to In other words, the authentication unit 32 determines OK when the member information storage unit 35 includes both a combination of the source external telephone number and the extension telephone number and a combination of the destination external telephone number and the extension telephone number. The result is returned to the extension SIP server unit 21. Otherwise, the determination result of NG is returned to the extension SIP server unit 21.

  Step 19: If the determination result from the community management server A is OK, the extension SIP server unit 21 uses the SIP communication request that has been waiting in step 17 as the destination with the extension number specified in the SIP communication request as a destination. Transfer to terminal (device C).

  Step 20: Through step 19, media (voice, video, application, etc.) are connected between the SIP terminal A and the virtual SIP terminal (device C). Thereby, for example, the virtual SIP terminal has an IVR function, and operates the device C, which is an actual device, using the device communication function unit 24 in accordance with a user operation.

  FIG. 6 is a sequence diagram showing a second operation example of this embodiment. The second operation example is a sequence when communication is performed from a mobile device in one home belonging to the same community to a device in another home via the mobile network. A difference from the first operation example shown in FIG. 5 is that a mobile device connected to the extension SIP server unit of the gateway device is originally taken out, and the mobile device sets an external telephone number different from the extension telephone number. It is a point you have. Even in this case, the mobile device makes a communication request to the extension SIP server unit of the gateway device (originally connected) through the external network, and the community management server sends the external phone number and the extension phone number of the gateway device. Communication is realized in the same procedure as the sequence of FIG. 5 by associating and holding an external telephone number other than the gateway device.

  Here, in the system shown in FIG. 1, a case will be described as an example in which communication is performed with a device C belonging to the same community management server A in β home in a state where the α home smartphone belonging to the community management server A is taken out. . In the community management server A, the member information shown in FIG. 4A is stored in the member information storage unit 35 in advance. That is, the smartphone is originally a device connected to the gateway device 1 (external telephone number 046-1, extension telephone number 30) and “090-1” (here, the telephone number is simplified). )), And the member information storage unit 35 stores two phone numbers of the smartphone.

  The device information storage unit 15 of the gateway device 1 stores the device information of FIG. 2A, and the device information storage unit 25 of the gateway device 2 stores the device information of FIG. 2B. And

  In the sequence illustrated in FIG. 6, in step 31, the smartphone acquires a member ID and the like from the community management server A and selects a member ID of a communication destination device, as in step 11 of FIG. 5. Thereby, a smart phone transmits a SIP communication request to the extension SIP server part 11 of the gateway apparatus 1 by step 32 similarly to step 12 of FIG. At this time, the smartphone accesses the extension SIP server unit 11 via the mobile network and the IP telephone network, and sets its own external telephone number (090-1) as the source information.

  Regarding the processing from step 33 to step 40 thereafter, the source device is not a SIP terminal A but a smartphone connected via a mobile network and an IP telephone network, and an external telephone is used as information on the source device. Since it is the same as Step 13 to Step 20 in FIG. 5 except that the external telephone number (090-1) is used instead of the number and the extension telephone number (046-1 # 30), the description thereof is omitted here.

  FIG. 7 is a sequence diagram illustrating a third operation example of the present embodiment. The third operation example is a sequence when communication is performed from a mobile device in one home belonging to the same community to a device in another home via the mobile network. The difference from the second operation example shown in FIG. 6 is that the member information storage unit of the community management server A is registered with the member information of member ID = 0002 (smartphone), and the member information storage unit of the community management server B Only member information of member ID = 9002 (device C) is registered in.

  Moreover, the community management server A and the community management server B are the “affiliated community” and hold the information of the community ID and URL of each other. The “affiliated community” is a flag indicating whether communication is permitted across the community. Thereby, even if it is communication of the apparatuses which do not directly belong to the same community, communication is implement | achieved when community management servers communicate.

  Here, in the system shown in FIG. 1, the device C belonging to the community management server B (participating community of the community management server A) is connected to the device C belonging to the community management server A in a state where the smartphone of α home belonging to the community management server A is taken out. A case of communication will be described.

  Step S51: As pre-processing, the community management server A and the community management server B exchange information that they are affiliated communities. That is, the community ID and URL of the partner community management server are transmitted and received to each other and stored in a storage unit (not shown).

  Step 52: The smartphone accesses the community management server A through the browser function, and acquires information about the members from the community management server A. The community management server A not only has its own community ID (= 12345), each member ID in its own community stored in the member information storage unit, and additional information, but also the community ID of the community management server B, which is an affiliated community ( = 56789), each member ID, additional information, etc. in the partner's community stored in the member information storage unit are also transmitted to the smartphone. The smartphone displays the acquired information on the browser (display). Note that the external telephone number #extension telephone number (destination) stored in the member information storage unit is not transmitted (disclosed) to the smartphone. The user selects the member ID (here, the member ID of the community management server B = 9002) of the device to be communicated using the browser function of the smartphone. The smartphone receives a user operation and transmits a communication request including the selected member ID to the community management server A.

  Step 53: When the community management server A receives the communication request from the smartphone, the community management server A activates the smartphone telephone application with a telto tag or the like to make a call. As a result, the smartphone requests the extension SIP server unit 11 of the gateway device 1 for SIP communication to the “device selected from the SIP terminal A”. At that time, the external telephone number (046-1) of the extension SIP server unit 11 is used as the destination, and the community ID of the community management server B (= 56789) and the selected member ID in the community (= 9002) are passed as subaddresses. The community ID of the community management server A (= 12345) is added to the destination in a specific format (046-1 # 56789 # 9002 # 12345 in the illustrated example). At this time, the smartphone accesses the extension SIP server unit 11 via the mobile network and the IP telephone network, and sets its own external telephone number (090-1) as the source information.

  Step 54: The extension SIP server unit 11 waits for the SIP communication request when a subaddress is added to the destination of the SIP communication request in a specific format. Then, referring to the device information storage unit 15, the address of the community management server corresponding to the community ID (= 12345) of the route origin designated as the destination (subaddress) of the SIP communication request is acquired, Sends a destination inquiry request for the member ID specified by the sub address. Here, the extension SIP server unit 11 refers to the community ID column corresponding to the external telephone number (090-1) set as the transmission source in the device unique ID of the device information storage unit 15, and Get the address.

  Step 55: The authentication unit 32 of the community management server A determines whether or not the device having the notified external telephone number is a member belonging to its own community. That is, the community management server A determines whether or not the notified outside line telephone number exists in the member information storage unit 35.

  Step 56: If it is determined that the authentication unit 32 is a member, the destination resolution unit 33 of the community management server A sends the destination of the member ID (= 9002) specified in the destination inquiry request of step 54 to the community management server B. Inquire. At this time, the destination resolution unit 33 of the community management server A notifies the community management server B of the external telephone number (090-1) of the caller smartphone.

  Step 57: The destination resolution unit 33 of the community management server B confirms whether or not the community management server A is a cooperative community. If it is a cooperative community, the notified external telephone number is stored in a storage unit (not shown) and used for the processing of step 62.

  Step 58: The destination resolving unit 33 of the community management server B returns the set (046-2 # 20) of the external telephone number and the internal telephone number corresponding to the member ID requested in S56 to the community management server A.

  Step 59: The destination resolution unit 33 of the community management server A returns the set of the external telephone number and the extension telephone number (046-2 # 20) notified from the community management server B to the extension SIP server unit 11.

  Step 60: The extension SIP server unit 11 transfers the SIP communication request that has been waiting in Step 54 to the destination returned in Step 59. At that time, the extension SIP server unit 11 adds a community ID in a predetermined format as a sub-address to the returned destination (046-2 # 20 # 56789 in the illustrated example). As a result, the existing line authentication is performed by the IP telephone network, and the telephone from the smartphone is transferred to the extension SIP server unit 21 of the gateway device 2.

  Step 61: The extension SIP server unit 21 of the gateway device 2 at the transfer destination waits for the SIP communication request when a subaddress is added in a specific format to the received SIP communication request. Then, the extension SIP server unit 21 inquires of the community management server B whether or not the caller's external telephone number is a member of the community community of the community management server B.

  Step 62: The authentication unit 32 of the community management server B determines that the source device is a member of the cooperative community if the notified outside telephone number is stored in the storage unit in step 57. If it is not stored in the storage unit, it is determined that the member is not a member of the cooperative community.

  Step 63: The authentication unit 32 of the community management server B returns the determination result (OK or NG) to the extension SIP server unit 21.

  Step 64: If the determination result from the community management server B is OK, the extension SIP server unit 21 uses the SIP communication request waiting in step 61 as a destination for the extension number specified in the SIP communication request. Transfer to terminal (device C).

  Step 65: In step 64, media (sound, video, application, etc.) are connected between the smartphone and the virtual SIP terminal (device C).

  In the present embodiment described above, the gateway device converts (unify) devices using various communication protocols into virtual SIP terminals, and then assigns a global ID (external line) issued by the existing external network (IP telephone network). Communication between devices between multiple homes is realized by using (telephone number). In other words, the community management server does not need to manage paying out global IDs such as external telephone numbers, but only manages the member IDs and destinations of each community, reducing the burden of development and operation of system developers. be able to.

In this embodiment, since the community management server holds the member ID and the destination in association with each other in the member information storage unit, each device can communicate without directly knowing the global ID of the communication destination. Even if you do not want to tell community members the global ID, you can communicate and prevent the spread of the global ID. That is, the receiving side does not need to inform the calling side of the global ID in advance, and the psychological usage barrier can be reduced even when the closeness of users between the incoming and outgoing is small.
For example, if you want to communicate with each other in a community where you have similarities, such as living in the same town or going to the same school, but not close enough to exchange each other's phone numbers For example, it can be effectively used when an electronic circulation board or an emergency contact network application is realized.

  Further, in this embodiment, by using an external telephone number as a global ID, an existing IP telephone network can be used for global ID assignment, authentication, and destination resolution. For example, it is possible to obtain a high level of forgery resistance equivalent to that of an external telephone number in an IP telephone network.

  Further, in the present embodiment, the mobile device is taken out of the house by storing the global ID and local ID of the device together with the global ID held by the device itself in the member information storage unit 35 of the community management server. Even when the gateway device is accessed via the mobile network, it is possible to communicate with devices of other members of the same community by specifying the member ID.

  In this embodiment, a plurality of community management servers set up affiliated communities in advance, so that even if the devices are not directly in the same community, the affiliated community management servers communicate with each other. By doing so, communication becomes possible.

  In addition, this invention is not limited to the said embodiment, Many deformation | transformation are possible within the range of the summary.
