Description

  The present invention relates to a communication service in which a communication network specifies an optimal communication partner and communication means in response to a communication request from a communication requester, and performs communication between communication terminals.

  In the conventional information communication system, the NW does not hold various terminal information accommodated in the network (NW) and various service information utilizing the NW.

  For example, in a fixed network Internet connection service, even if a user constructs a home network at home, sets a PC, a tablet, an NW disk, and various sensors, and constructs an environment that provides some service in the home, Then you cannot recognize and manage the service.

  Further, in the conventional information communication system, even if the connection condition is specified in the NW, the terminal that satisfies the connection condition, its address, and the communication condition for reaching the terminal are not solved.

  What can be achieved with the current NW is a name resolution (IP address) using a domain name and a telephone number connection resolution for a specific service provided by the NW such as a telephone (see Non-Patent Documents 1 and 2). ).

  Also, once in connection processing after connection resolution, a plurality of communication processing means are not provided to end-to-end terminals.

  In addition, conventional NWs cannot manage services and terminals provided by using NWs, and NWs cannot provide communication processing functions including connection processing. Therefore, some HyperGrant businesses such as Google and Apple There is a situation where a person constructs an integrated service on his own service platform. In these models, a service provider basically integrates and provides a plurality of services in a vertically integrated manner, and therefore, it is not possible to provide a service by a plurality of services or a mutual introduction of a plurality of services. For example, "Toyota, Nissan and other vehicles with different manufacturers use the ITS (Intelligent Transport Systems) information provided by the Ministry of Land, Infrastructure, Transport and Tourism to use the Navi service provided by general businesses" An open environment that can be combined is not provided. Further, in the OTT (Over The Top) / NW carrier model, NW information and service information are basically divided, and therefore, an advanced service utilizing the NW function cannot be provided. Therefore, the conventional NW can only provide a service function by connecting a client terminal and a server, assuming that the IP (Internet Protocol) packet only exists.

P. Mockapetris, “DOMAIN NAMES-IMPLEMENTATION AND SPECIFICATION”, RFC1035, IETF Network Working Group, November 1989, [online], [searched January 23, 2015], Internet <URL: https: // www. ietf.org/rfc/rfc1035.txt> H. Alvestrand, “Real Time Protocols for Browser-based Applications”, draft-ietf-rtcweb-overview-13, IETF Network Working Group, 2014/11/28, [online], [January 28, 2015 search ] Internet <URL: http: //datatracker.ietf.org/doc/draft-ietf-rtcweb-overview/? Include_text = 1>

  As described above, the conventional NW is basically only for passing IP packets, although some services such as name resolution (IP address) and telephone number connection resolution are provided. On the other hand, with recent diversification of communication means / communication forms and diversification of service forms, higher functionality of NW itself has been demanded.

  The present invention has been made in view of the above problems, and an object of the present invention is an information communication system capable of dealing with a wide variety of communication means, communication forms, service forms, etc., and capable of providing advanced services, and its A communication control method and program are provided.

  More specifically, the NW can respond to the communication requester's dynamic communication request with the information of the service / terminal accommodated by the NW, and the communication requester can flexibly specify the connection condition to the NW. The purpose is to be able to carry out more advanced connection resolution and communication processing than conventional communication services, such as being able to carry out simple connection processing.

In order to solve the above problems, a system according to the present invention is accommodated in a network in an information communication system in which a terminal accommodated in a network connects to another terminal that is a desired communication partner and performs information communication. Each terminal information and service information related to the terminal and service / terminal information registration means for storing service / terminal information including communication means information for the terminal, and a connection destination inquiry from the communication request source terminal, Based on the service / terminal information registered by the information registration means and the network information provided in the network, the connection destination address information matching the communication conditions included in the connection destination inquiry and the communication means information to the connection destination are resolved. A connection resolution means for responding to the communication request source terminal with the resolved connection destination address information and communication means information, and a communication request Receiving a connection control request received from the terminal, so that the communication request source terminal can communicate to the communication partner terminal, and a communication processing means for performing communication control specified by the communication means information included in the connection control request Inquiries and responses between the communication request source terminal and the connection resolution means use a message format of DNS (Domain Name System) protocol, and include the communication condition in the domain name of the query in the DNS protocol. And

Also, the method according to the present invention is an information communication system in which a terminal accommodated in a network connects to another terminal that is a desired communication partner, and performs information communication, between a communication request source terminal and a communication partner terminal. In the communication control method that enables communication between the terminals , the service / terminal information registration means includes service information and terminal information that includes each terminal information accommodated in the network, service information related to the terminal, and communication means information to the terminal. and a registration step to register, connected resolution unit accepts a communication request destination inquiry received from the source terminal, the network information provided in the service terminal information and the network registered with the service terminal information registration step Based on this, the connection destination address information that matches the communication conditions included in the connection destination inquiry and the communication means information to the connection destination are resolved. A connection solved step of responding the resolved destination address information and communication unit information to the communication request source terminal, the communication processing unit receives a received from a communication request source terminal connection control request, the communication partner from the communication request source terminal A communication processing step for performing communication control specified by the communication means information included in the connection control request so as to enable communication with the terminal, between the communication request source terminal and the connection resolution means in the connection resolution step The inquiry and response use a message format of DNS (Domain Name System) protocol, and the communication condition is included in the domain name of the inquiry in the DNS protocol .

  According to the present invention, the NW can grasp information on terminals and services accommodated by itself. For this reason, it becomes possible to reply to an optimal communication destination and communication means in response to an inquiry including a destination solution request from a communication requester connected to the NW to a communication partner and communication condition designation. Also, since communication means corresponding to the communication conditions are provided, real-time communication, NAT (Network Address Translation) / FW (Fire Wall) network, VPN (Virtual Private Network) private communication, SMS (Short Message Service Service) Start-up and message distribution become possible.

  Therefore, by using the present invention, the NW can highly intervene communication between the client and the server. In addition, future real-time communication and IoT (Internet of Things) communication will be possible.

FIG. 5 is a diagram illustrating an example of a service name, FIG. 5 is a diagram illustrating a specific example of a domain name, FIG. 6 is a diagram illustrating a registered route and distribution of service / terminal information, and FIG. 7 is a diagram illustrating a resolution process of a connection resolution unit. 8 and 9 are diagrams for explaining connection resolution using DNS (Domain Name System), and FIG. 10 is a diagram for explaining the operation of the communication processing unit.

  As shown in FIGS. 1 and 2, the information communication system according to the present invention includes a service / terminal information registration unit 100, a connection resolution unit 200, and a communication processing unit 300.

  The service / terminal information registration unit 100 has a function of registering / holding “service / terminal information”, which is information about an accommodation terminal accommodated in the NW and a connection destination, and a service related to the accommodation terminal.

  The accommodation terminal to be registered in the service / terminal information registration unit 100 may be connected to a fixed network included in the NW or connected to a wireless communication network included in the NW. A typical example of the former is when a user has built a home network at home. In this case, not only home devices such as a home gateway (HGW) installed in the user's home, Computer devices such as NW discs, various home appliances such as Blu-ray recorders, and M2M terminals such as video surveillance cameras and agricultural sensors are also included in the “accommodating terminal” of the present invention. As a typical example of the latter, in addition to the user's smartphone, the wireless communication module itself and a terminal (for example, a car navigation terminal) on which the wireless communication module is mounted are also included in the “accommodating terminal” of the present invention.

  Further, the services to be registered in the service / terminal information registration unit 100 include services provided by a communication carrier or service provider, as well as services built by the user. Typical examples of the former include a monitoring service provided by a security company and a P2P (Peer to Peer) type communication service such as WebRTC (Web Real-Time Communication) provided by a communication carrier. Typical examples of the latter include a file sharing service constructed by a user on a home network, a streaming service, and the like.

  The service / terminal information registered in the service / terminal information registration unit 100 includes a terminal identifier, a domain name, and a communication capability, as shown in FIG.

  The terminal identifier included in the service / terminal information is an identifier that can uniquely identify the accommodating terminal on the NW, and, for example, a MAC (Media Access Control) address is used.

  The domain name included in the service / terminal information is information obtained by integrating the attribute information of the accommodation terminal and the service attribute information excluding the terminal identifier, and is a condition for using the information and service that can identify the accommodation terminal. Contains information to obtain. In the example of FIG. 3, the domain name includes a terminal name, a service name, a service type, an address name, and a line number.

  The terminal name included in the domain name is a name given separately from the terminal identifier. In a typical example, the terminal name is identified in a higher layer than the terminal identifier. The terminal name can be arbitrarily determined by the service provider, NW provider, and user. For example, as described above, when a MAC address is used as a terminal identifier, a host name is used as a terminal name.

  The service name included in the domain name identifies the service by NW, and is provided between the telecommunications carrier and the service carrier or between the telecommunications carrier and the user as shown in FIG. The service is roughly classified into those prescribed in advance for each service to be performed and those uniquely prescribed by the user or service provider. In the former case, for example, when building a HEMS service of an electric power company, use the HEMS service by domain name by specifying, for example, Topco-HEMS (Tokyo Electric Power Company- Home Energy Management System) as the service name. I understand that. On the other hand, with respect to the latter, a character string arbitrarily added with a predetermined character string (in the present invention, “DIY”) indicating an original rule is used.

  The service type included in the domain name indicates the type of service. For example, each service type is represented by a predetermined character string. The telephone service is “TEL”, the Internet connection service is “Internet”, and M2M. The (Machine to Machine) service is “M2M”, the VPN service is “VPN”, and the WebRTC service is “WebRTC”.

  When the accommodation terminal is a fixed terminal, the address name included in the domain name indicates the geographical address of the fixed terminal, and for example, a postal code with an address or the like, a latitude / longitude, or the like is used. As an example, when the address is “3-9, 9-3 Midoricho, Musashino City, Tokyo”, there is one that is described as “180-0012-3-9-11”. On the other hand, when the accommodating terminal is a mobile terminal, the address name is optional, and if necessary, information indicating whether the mobile terminal is a home (for example, a home) or a predetermined destination The geographical address is indicated by a zip code or the like as described above. When the domain name includes an address name in this way, for example, it is possible to specify a batch destination of sensor terminals connected to a certain address, search for mobile terminals located in a certain address, and the like. .

  The line number included in the domain name is a number assigned to the accommodation terminal / user / contract by the NW carrier. In the case of a fixed terminal, for example, a customer number or a line number can be cited. For example, a SIM (Subscriber Identity Module) number that is a mobile line number may be used.

  The communication capability included in the service / terminal information indicates the communication capability of the accommodated terminal such as a protocol, an application, and a function that can be supported by the accommodated terminal. For example, “the browser of the accommodation terminal can be equipped with WebRTC, so that real-time communication by WebRTC is possible”, “since mobile phone supports SMS, terminal activation and message delivery by SMSPush are possible” Etc.

  An example of the above service / terminal information is shown in FIG. The example of FIG. 5 is an example of service / terminal information associated with a certain user.

  The service / terminal information registration route to the service / terminal information registration unit 100 and its distribution are shown in FIG. As shown in FIG. 6, the registration route of service / terminal information is based on the user registration route via the customer controller provided to the user by the telecommunications carrier, the service carrier registration route by NW-API, and the operation (OpS). Examples include carrier registration routes. The service / terminal information registered in the service / terminal information registration unit 100 is distributed / synchronized to the connection resolution unit 200 and used in the resolution process in the connection resolution unit 200.

  As shown in FIG. 7, the connection resolution unit 200 receives an inquiry specifying the communication partner and communication conditions from the communication requester terminal 13, resolves the communication means to the communication partner terminal 21, and at the communication means The destination address as the connection destination is resolved, and the destination address and communication means information are returned to the communication requester terminal 13. Note that there may be one or more connection destinations to be solved here. The resolution process of the connection resolution unit 200 refers to the service / terminal information distributed from the service / terminal information registration unit 100, and refers to the intra-network communication network information that can be referred to in the NW as necessary. What is necessary is just to acquire the destination address information and communication means information that match the other party and communication conditions. Examples of the intra-network communication network information include facility management information in the NW, NW function information, terminal address information assigned to the connection destination terminal, and the like. The communication means information that is response information indicates a protocol application or the like necessary for communicating with the connection destination. Here, it should be noted that the communication means information may include a plurality of pieces of communication means information and the order thereof as necessary. For example, when three communication means information such as terminal activation via SMS, WebRTC signaling, and ICE server are obtained in the same order as a result of the solution processing, these information and destination address information in each communication means information are included.

  As an example of specific implementation of the inquiry and response to the connection resolution unit 200, an example using an existing DNS protocol or mechanism will be described.

  As shown in FIG. 8, the inquiry message is realized by a “DNS query” message, and the response message is realized by a “DNS answer” message.

  FIG. 9 shows a specific message format usage example. In order to define that the DNS protocol is used in this method, the Z bit, which is a reserved bit of the DNS message header, is set to a predetermined value (for example, 001) when the present invention is used. As a result, when a DNS message with Z = 001 set is received, the solution processing provided by the present invention is applied.

  In the query, the domain name of the query is stored in the Question section of the DNS message format as in the case of DNS. In the case of the present invention, the domain format defined in the present invention is stored. By storing the defined domain name, the connection resolution unit 200 of the present invention can specify the terminal name, service name, service type, address name, and line number that the communication requester desires to connect to.

In the response, the answer section of the DNS message format is used, and the domain name and the destination address resolved by the connection resolution unit 200 are stored in the NAME and RDATA fields, respectively. When there are a plurality of resolved connection destinations, a plurality of values are stored.
Further, the communication means information solved by the connection resolution unit 200 is stored in the Additional section of the DNS message format. For example, when a communication requester requests WebRTC as a service type, and the connection resolution unit 200 selects an optimal WebRTC server or ICE server from a plurality of candidates such as the communication requester's service or location, the selection is made. The domain name and destination address of the WebRTC server and the ICE server are stored in the Additional section, and the communication requester is responded.

  As shown in FIG. 10, the communication processing unit 300 provides an appropriate NW function to the communication requester terminal 13 and the communication partner terminal 21 in accordance with the communication means information solved by the connection resolution unit 200, and performs communication processing. It is a functional part to perform. The communication processing unit 300 includes a terminal control unit 310, a connection control unit 320, and a transfer control unit 330.

  The terminal control unit 310 is provided with various functions for remotely starting and monitoring the terminal and for initial setting of the terminal. Specific examples include a WOL (Wake On LAN) function for starting a terminal such as a PC on a LAN, an SMS function for transmitting information to a mobile terminal or a fixed terminal telephone number, and initial setting of the terminal. The Bootstrap function is configured.

  The connection control unit 320 has a signaling processing function for enabling real-time communication, and has a CSCF (Call Session Control Function) function of SIP (Session Initiation Protocol) and a WebRTC server function.

  The transfer control unit 330 is provided with a NAT / FW network traversal function, a VPN transfer function using a VPN Gateway (VPN-GW), and a cache function for realizing a transfer service between the user and the service.

  Next, the operation of the information communication system according to the present embodiment will be described with reference to FIGS. 1 and 2 again. In this information communication system, as shown in FIG. 1, first, each accommodation terminal 11-12 accommodated in the NW registers service / terminal information in the service / terminal information registration unit 100 (step S10 in FIG. 1). Next, the terminal 13 of the communication requester makes an inquiry specifying the communication partner and communication conditions to the connection resolution unit 200 (step S21 in FIG. 1), and the connection resolution unit 200 responds with destination address information and communication means information. (Step S22 in FIG. 1). The communication requester terminal 13 that has received the response starts connection processing with the communication partner terminal 21 via the communication processing unit 300 based on the received response (step S31 in FIG. 1). Communication is possible (step S32 in FIG. 1). In FIG. 1, the communication requester terminal 13 is accommodated under a fixed terminal 14 such as a home gateway, and the communication partner terminal 21 is accommodated under a mobile terminal 22. Yes.

  In the example of deployment in FIG. 2, a gateway device (xGW) 31 with a predetermined line number is accommodated in the NW 1 via a fixed line, and a service provider set up by the service provider is subordinate to the xGW 31. A terminal 32 and a DIY terminal 33 uniquely installed by the user are accommodated. A gateway device (xGW) 41 with a predetermined SIM number is accommodated in the NW1 via a wireless communication network, and under the xGW 41, a service provider terminal 42 installed by a service provider, A DIY terminal 43 uniquely installed by the user is accommodated. In addition, NW1 is connected to NW2 related to another provider, and servers 51 to 53 that provide various services are arranged. In such a deployment example, the processes of steps S10, S21 to S22, and S31 to S32 described above with reference to FIG. 1 are performed.

  According to the present invention, the NW can grasp information on terminals and services accommodated by itself. For this reason, an optimal destination address and communication means information can be answered in response to an inquiry including a communication partner and communication conditions from a communication requester connected to the NW. Also, since communication means corresponding to the communication conditions is provided, real-time communication, NAT / FW network traversal, VPN private communication, SMS terminal activation and message distribution are possible.

  By using the present invention, the NW can intervene highly in communication between the client and the server. In addition, future real-time communication and IoT communication will be possible. An optimal NW function can be provided according to the request of the service provider or communication requester. In addition, NW providers can provide service registration for multiple service providers, and can provide NW services that multiple service providers can interoperate to enable connection resolution and communication connections from different service providers. It becomes.

  Further, by using the present invention, not only a service provided by a communication carrier but also a communication service uniquely set by a communication user, a service provider can provide a communication network service using a communication network of the communication carrier. .

  Examples of applying the present invention will be described below.

  An example of connecting to a home network from a destination will be described with reference to FIG. The present embodiment is an example of accessing a network storage disk installed at home using a mobile terminal such as a smartphone or a tablet.

  In the system of the present invention, the network storage disk (NAS) 62 of the home network 63 installed by the user is registered in advance in the service / terminal information registration unit 100 of the system of the present invention. In this case, the NAS 62 is provided with, for example, NAS (Network Attached Storage) from Buffaro as a domain name.

  In the fixed network, a global IP address is issued to a terminal such as a home gateway (HGW) 64 at the time of line opening or ISP access. For example, when an IP address is issued to a user using the AAA / DHCP function, the connection resolution server 65 (“AAA (DHCP) / DDNS” in FIG. 11) associates the line information with the IP address.

  As such an implementation example, there is DDNS (Dynamic DNS). As a result, the connection resolution unit 200 can maintain the relationship between the home home domain defined by the user and the global IP address assigned to the fixed line. Further, in order to connect to the home, it is assumed that the HGW 64 has a fixed local IP address assigned to the NAS 62 and port forwarding is set. This setting may be set by the user himself / herself at the time of service registration, or may be set from the NW side as a carrier service.

  In this embodiment, when the communication requester terminal 61 makes an inquiry to the connection resolution unit 200 for name resolution of a domain name including a port number that means connection to the NAS 62 of the home network 63, the NAS 62 is sent to the communication requester terminal 61. The global IP address assigned to the fixed line of the home network 63 in which the IP address is accommodated is resolved. Thereafter, the communication requester terminal 61 communicates with the HGW 64 and transfers the communication to the NAS 62 in the home network 63 based on the port number designated by the HGW 64.

  An embodiment in which P2P type real-time communication is performed between terminals using WebRTC will be described with reference to FIGS. In this embodiment, an example is shown in which a terminal at home calls a smartphone on the go and performs video communication or the like. For example, it corresponds to a case where a mother at home calls a smartphone of a child on the go and performs video communication.

  As shown in FIG. 12, the communication requester terminal 71 inquires the connection resolution unit 200 with a domain name in which the mobile phone number of the communication partner terminal's smartphone and the WebRTC name as the communication means are incorporated. The connection resolution unit 200 understands that the communication requester desires WebRTC communication addressed to the smartphone of the mobile network managed by the communication requester, and is an optimal SMS-C, WebRTC server for connecting to the communication partner. , Communication means information that is an ICE server is selected. The connection resolution unit 200 responds to the communication requester terminal 71 with the communication means information.

  At this time, the communication requester terminal 71 is notified of the SMC-C address, and the communication requester terminal 71 guides the activation of the communication partner terminal 72 and the WebRTC server connection (FIG. 12). In some cases, the connection resolution unit 200 instructs the communication processing unit 300 to start the communication partner terminal 72 and to connect to the WebRTC server without notifying the SMS-C address (FIG. 13).

  In FIG. 13, after the inquiry from the communication requester terminal 71 of FIG. 12 and the response of the communication means information from the connection resolution unit, the communication requester terminal 71 notified of the communication means from the connection resolution unit 200 starts first. To the SMS-C, and causes the communication partner designated by the telephone number to activate the terminal and connect to the WebRTC server via SMS. The WebRTC application is activated using SMS push.

  The communication partner terminal 72 receives the SMS push message and activates WebRTCAPL based on the connection APL information defined in the message. Thereafter, the communication partner terminal 72 performs connection processing to the WebRTC server. At this time, the communication requester terminal 71 is also connected to the WebRTC server, and when the partner server connection is confirmed, a connection request is transmitted by an Offer message. At this time, in order to exceed NAT / FW, the ICE server confirms in advance how the external address of the device looks, and notifies the communication partner with an Offer message. If the communication partner terminal 72 determines that the connection can be made with respect to the received Offer message, the communication partner terminal 72 inquires of the ICE server what the external address of the communication partner terminal 72 looks like and returns it to the communication requester terminal 71 with an Answer message. This series of communication capability exchange and communication connection processing enables real-time communication between the communication requester terminal 71 and the communication partner terminal 72.

  An embodiment in which a network camera connected to a specific area where a monitoring service of a security company is located is searched and a part thereof is called and video monitoring is performed will be described with reference to FIGS.

  In the example of FIG. 14, the monitoring server 81 makes an inquiry by designating a network camera installed in 3-chome Tokura, Kokubunji, Tokyo. Here, when SECOM service provider A and ALSOC service provider B are in a partnership, and the public surveillance camera information set up by Kokubunji City is also used, the service provider's monitoring service is the service provider A Queries the service provider B and the monitoring camera of the local government by the OR condition of the logical operator. In addition, the terminal name is designated as a WILD card in order to search for all terminals installed, and the WILD card is designated below the address of the address. In response to this inquiry, the connection resolution unit 200 searches for and responds to candidate monitoring camera information and connection information necessary to connect to the terminal.

  FIG. 15 shows an example in which the monitoring server 81 selects a communication partner terminal 82 as a candidate and calls a monitoring camera. Specifically, when the monitoring server 81 transmits a connection request to the communication partner terminal 82 to the communication processing unit 300, the IP-Push function unit of the communication processing unit 300 is a monitoring camera in which the communication partner terminal 82 is accommodated. The mobile terminal 83 that is a GW is instructed to start the communication partner terminal 82. The mobile terminal 83 instructs the communication partner terminal 82 to start up and distribute the video, and the communication partner terminal 82 starts up and starts video distribution according to the instruction. On the other hand, the portable terminal 83 forms a connection with the monitoring server 81, and the video data captured by the communication partner terminal 82 is distributed to the monitoring server 81. When it is desired to change the angle of view and the direction of the camera, the monitoring server 81 transmits an instruction to the communication partner terminal 82 by Push communication using WebSocket.

  As mentioned above, although this invention was explained in full detail, this invention is not limited to this. For example, in the present invention, the network mode such as the network connection mode of each terminal is unquestioned. In addition, the service / terminal information described in the above embodiment is an example, and in particular, information included in the domain name can be appropriately selected according to the service use, the network form, and the like. In the above embodiment, WebRTC, IP-Push, ICE, and the like have been described as communication means. However, these are examples, and the present invention can be applied to other communication means.
