Description

  The present invention relates to a communication system that speeds up communication while ensuring safety of communication in an apartment house equipped with existing communication equipment that mainly performs wired communication.

  Conventionally, in a building such as an apartment house or an office building, communication equipment for in-house communication has been widespread. This type of communication equipment is provided for the purpose of making a call with video between the common entrance of the apartment house and the dwelling unit, or for emergency broadcasting in the event of a fire.

  On the other hand, in recent years, terminals that can be connected to a wide area network represented by the Internet have been used to enjoy services provided through the wide area network. As described above, in a building where communication facilities already exist, the existing communication facilities are connected to a wide area network via a gateway. Applications of connecting communication facilities to a wide area network include outsourcing of operations for monitoring for disaster prevention and crime prevention, and outsourcing of operations for managing facilities attached to buildings.

  For example, Patent Document 1 discloses that a housing information board provided in each dwelling unit in a housing complex and a lobby intercom provided in a common entrance of the housing complex are connected to a monitoring board arranged in a manager's room. In addition, there is disclosed a monitoring control system for an apartment house that is configured to centrally monitor and control a lobby intercom and that has a monitoring panel connected to the Internet via a gateway and a router device.

  In the technique described in Patent Document 1, a center server operated by a management company is connected to the Internet, and the center server provides various services required in an apartment house. As the types of services, an email processing service, power consumption monitoring, forgetting to turn off monitoring, a return home notification service, and the like are described.

Japanese Patent Laid-Open No. 2003-309662

  By the way, in recent years, there are servers that provide services that need to communicate interactively through the Internet, such as Net Super, and if you want to enjoy this type of service using a home information board, In collective housing, in addition to signals used for calling, monitoring, control, etc., signals for receiving this type of service must be transmitted on the communication path between each housing information panel and the monitoring panel. Will significantly increase traffic.

  In housing complexes called internet condominiums, etc., there are cases where broadband communication channels using optical fibers etc. are laid, but the bandwidth of communication channels in general housing complexes is that of audio signals, video signals, It does not have a bandwidth that can handle a service that communicates interactively through the Internet, but can transmit control signals and monitoring signals.

  On the other hand, a private network constructed using a narrow-band communication path of this type is provided with an authentication function in the monitoring panel (or a server provided in the private network), and a specific connection for which a contract is made in advance. In many cases, the safety of communication using the Internet is secured.

  In addition, the connection from the terminal installed in each dwelling unit to the contracted connection destination can be easily made by simply calling the service from the terminal installed in each dwelling unit. Compared to the case of connection, it can be said that the convenience is high.

  Moreover, when connecting to a specific contractor who has contracted in advance via the local network, the server that provides the service has already been registered, so there is no need to send information for new registration Compared to the case where a broadband router is installed in each dwelling unit and the terminal installed in each dwelling unit is connected directly to the server without going through the local server, the registered information does not flow on the Internet, so there is a risk of information leakage. Sexuality is reduced.

  Although the above-described example has been described for an apartment house, office buildings may have similar problems.

  The present invention has been made in view of the above-mentioned reasons, and its purpose is to enable high-speed communication by enabling connection to the Internet from a terminal provided in a building without passing through a local network, An object of the present invention is to provide a communication system that can easily use the service for the premises without impairing the convenience of the service for the premises provided on the premises network.

  In order to achieve the above object, the present invention provides a terminal having identification information used for communication on a private network constructed in a building, and identification information used for communication on the private network by constructing a private network together with the terminal. 1st communication which has the local server which it has, and the external server which provides a service when it receives the use request from a terminal connected to the Internet, and constructs a local network between the terminal and the external server A path including a path and a path including a second communication path that is wider than the first communication path are juxtaposed, and the terminal makes a first request when using a service provided by an external server. After the communication identification information is received, the second communication path is received after the communication identification information is issued to the external server by transmitting the identification information of the local server to the external server. choose And wherein the Rukoto.

  In addition, the terminal has a function of transmitting the terminal identification information to the local server via the first communication path when making a use request for the service provided by the external server. Upon receipt of the use request, it has a function of transmitting the identification information of the local server and the identification information of the terminal to the external server, and the external server includes a contractor storage unit in which identification information of the local server providing the service is registered in advance. The identification information collation unit for collating the identification information of the local server received from the local server with the contractor storage unit, and the identification information for communication when there is matching identification information in the collation result of the identification information verification unit and the service And an identification information management unit that transmits the identification information for communication to the terminal using the identification information of the terminal that has requested use of the terminal, and the terminal passes through the first communication path from the external server. To after receiving the communication identifier may have the ability to access the external server via the second path by using the communication identifier.

  Alternatively, the terminal has a function of transmitting the identification information of the terminal to the local server via the first communication path when making a use request for the service provided by the external server. When the use request is received, the identification information of the local server and the identification information of the terminal are transmitted to the external server. The external server provides the service providing server that provides the service and the identification information of the local server that provides the service. And a service management server having a contractor storage unit in which the correspondence relationship between the service provider server and the identification information of the service providing server is registered. The service management server checks the identification information of the local server received from the local server with the contractor storage unit. Communication identification information is issued when there is matching identification information in the verification result of the identification information verification unit. The communication identification information is transmitted to the terminal using the identification information of the terminal that has requested use of the service, and the communication identification information is transmitted to the server providing server using the identification information of the service providing server extracted from the contractor storage unit. The terminal receives a communication identifier from the service management server via the first communication path, and then uses the communication identifier to perform service via the second path. You may have the function to access a provision server.

  Further, the local server has a traffic storage unit that stores the traffic amount required for each type of service provided by the external server, and a traffic monitoring unit that monitors the traffic amount of the first communication path. If the sum of the traffic volume for the service requested for use and the traffic volume monitored by the traffic monitoring unit does not exceed the prescribed threshold value, the second terminal even after the terminal receives the communication identification information A configuration in which the first communication path is used without selecting the communication path may be used.

  In addition, the terminal has a function of determining whether there is an abnormality in the second communication path. If an abnormality occurs in the second communication path even after receiving the communication identification information, the first communication path It is also possible to use a configuration that uses.

  The terminal has a WAN interface connected to the Internet, and a first terminal having a router unit having a LAN interface connected to the first communication path of the local network via the gateway unit; When the second terminal uses the second terminal to make a request for using the service, the second terminal passes through the first communication path. The identification information is acquired from the local server, the identification information of the first terminal is acquired, and the identification information of the first terminal and the local server is transmitted to the external server via the WAN interface of the router unit. The communication identification information issued by the external server may be acquired.

  According to the configuration of the present invention, when a terminal requests the use of a service to a local server via the first communication path of the local network, the local server transmits the service to the pre-contracted external server. Since the identification information and the terminal identification information are transmitted and the communication identification information is issued by the external server, the terminal can safely acquire the communication identification information. Since the terminal that has acquired the communication identification information transmits the communication identification information to the external server using the second communication path that is faster than the first communication path, the user of the terminal does not perform an operation. In the second communication path, a link between the external server and the terminal is automatically established. Therefore, it is possible to quickly receive the service without the trouble of inputting the ID and password. As described above, the terminal uses the first communication path when acquiring the communication identification information, but the second communication path is automatically selected when receiving the service. Therefore, the band can be switched seamlessly, and the service can be enjoyed with an operational feeling as if using only the local network.

  Moreover, since the local server transmits the identification information of the local server and the identification information of the terminal to the external server, but does not transmit information about the user of the terminal, the personal information of the user held in the local server Will not leak. Furthermore, before receiving service provision at the terminal, authenticated communication identification information is acquired by communicating between the local server and the external server with which a trust relationship has been established. While enabling high-speed communication, it becomes possible to perform communication safely.

  In a configuration in which the external server includes a contractor storage unit, and the external server issues communication identification information and transmits it to the terminal, the terminal requests use of the service from the external server via the local server. Communication safety is ensured by the server.

  In a configuration using a service providing server and a service management server as external servers, the service management server is managed by an administrator different from the service providing server, and the terminal and the service providing server are associated with each other in the service management server. At the same time, the service management server issues identification information for communication, so that when there are a large number of unspecified service providing servers, the terminal information is not dispersed and the safety of the terminal information is ensured. can do.

  In the configuration in which the communication path is selected based on the sum of the required traffic volume according to the type of service and the traffic volume of the first communication path, when the traffic volume of the first communication path is small, the first communication path is Since the second communication path can be used preferentially, the safety of communication is increased by interposing the local server while ensuring the communication speed.

  In the configuration in which the first communication path is used to communicate with the external server when there is an abnormality in the second communication path, even if an abnormality occurs in the second communication path, the first communication path is duplicated. Communication via the communication path can be maintained.

  When the terminal is constituted by the first terminal connected to the local network and the second terminal connected to the router unit provided in the first terminal and constructing the LAN, as the second terminal A terminal device such as a personal computer or a television receiver connectable to the Internet can be used, and the amount of information that can be displayed can be increased to improve convenience.

In order to connect the local network NT1 to the Internet NT2 which is a wide area network, a gateway 12 is connected to the communication path Ls of the local network NT1. That is, the local network NT1 is connected to the Internet NT2 via the gateway 12. With this configuration, the apartment house server 10 and the dwelling unit terminal 20 can communicate with the external server 30 provided on the Internet NT2.

  Services (calendar, weather forecast, net super, etc.) that can be enjoyed by the dwelling unit terminal 20 from the external server 30 are selected by performing interactive input using the display device 21 and the operating device 22 at the dwelling unit terminal 20. can do. That is, an application program for selecting a service provided in advance (hereinafter abbreviated as “application”) is set in the dwelling unit 20, and the external server 30 is selected by selecting an application corresponding to the service. It becomes possible to enjoy the service by.

  The configuration described above is realized using the existing local network NT1 in the apartment house B, and the local network NT1 can be said to be a backbone network.

  By the way, in the example shown in FIG. 1, the communication path Lt that is faster (broadband) than the local network NT1 is described together with the communication path Ls of the local network NT1. That is, in communication between the dwelling unit terminal 20 and the external server 30, it is possible to selectively use the communication paths Ls and Lt and perform communication via the communication path Ls and communication via the communication path Lt. Yes. The selection of the communication paths Ls and Lt is performed by the switching means 24 provided in the dwelling unit terminal 20, as shown in FIG.

  That is, the dwelling unit terminal 20 is provided with a basic communication interface 25 for connecting to the communication path Ls and a high-speed communication interface 26 for connecting to the communication path Lt. And the high-speed communication interface 26 is selected as necessary. Conditions for the switching means 24 to select the basic communication interface 25 and the high-speed communication interface 26 will be described later.

  The communication path Lt is a communication path between the router 13 installed to connect to the Internet NT2 and the dwelling unit terminal 20, and can be used for either a wired type or a wireless type. In recent years, since a wireless LAN is frequently used in a home, the router 13 having a function as a wireless LAN access point is used in this embodiment. Therefore, a high-speed communication interface 26 having a wireless LAN client function is used. The router 13 uses a broadband router. The router 13 can be provided in each dwelling unit, but a single router 13 may be shared by a plurality of dwelling units by using a wireless LAN standard such as WiFi. The router 13 may be provided outside the apartment house B.

  Below, the procedure in which the dwelling unit terminal 20 communicates with the external server 30 is demonstrated. Here, the identification information of the dwelling unit terminal 20 is “ABCD”, the identification information of the apartment house server 10 is “A001”, and the communication identification information issued by the external server 30 in response to a communication request from the dwelling unit terminal 20 is “A301KHYG2331”. And The communication identification information is a one-time password at the start of work. When the external server 30 issues the communication identification information, an expiration date is set for each communication identification information. The expiration date is set in date and time up to the minute unit. For example, if the expiration date is set to “200906262030”, the communication identification information is valid until 20:30 on June 26, 2009.

  In the present embodiment, the case where a net super order is made using the dwelling unit terminal 20 is taken as an example, and therefore, the external server 30 has a function of receiving a product order in the net super. In addition, in the net supermarket, it is necessary to present items of handled products to the dwelling unit terminal 20, and thus the external server 30 has a function of presenting handled products to the dwelling unit terminal 20. There are two types of formats for presenting handled products: a list format and a flyer format that includes product images. Since the screen size of the display device 21 of a general dwelling unit 20 is around 5, the list format It is desirable to present at.

  As shown in FIG. 3, in order for the dwelling unit terminal 20 to access the external server 30, first, an application for using the net super at the dwelling unit terminal 20 is selected. In this application, the housing server 10 is notified that there has been a request for using the net supermarket from a specific dwelling unit terminal 20 (P1). Since communication from the dwelling unit terminal 20 to the apartment house server 10 is communication within the local network NT1, the switching means 24 of the dwelling unit terminal 20 selects the backbone communication interface 25, and the dwelling unit terminal 20 The use request of the net super and the identification information (ABCD) of the dwelling unit terminal 20 are transmitted to the collective housing server 10 through the road Ls.

  Communication with the external server 30 providing the net super service is mediated by the apartment house server 10. Therefore, the housing complex server 10 that has received a request for use of the net super from the dwelling unit terminal 20 makes a use request for the net super to the external server 30 (P2). When requesting the use of the net super to the external server 30, the external server 30 is notified together with the identification information (A001) of the apartment house server 10 and the identification information (ABCD) of the dwelling unit 20 that has made the use request of the net super. .

  Further, in the apartment house server 10, the name and address of the apartment house B are associated with the identification information of the apartment house server 10 as shown in Table 1, and the room number, the resident, and the contact information in the apartment house B as shown in Table 2. Are associated with the identification information of the dwelling unit terminal 20, these pieces of information are transmitted to the external server 30. By this operation, the resident who operates the dwelling unit terminal 20 can log in when enjoying the service without entering identification information or a password, and can further specify the delivery destination of the product to the external server 30. It becomes possible to notify.

  The external server 30 has a function of accepting a product order of the net super, and a contract in which the identification information of the multi-dwelling server 10 and the address / name of the multi-dwelling house B are associated with the multi-family housing B that has a net super user contract. The contractor storage unit 31 for storing the housing information, the identification information verification unit 32 for verifying the identification information of the multi-dwelling server 10 received from the multi-dwelling server 10 with the contractor storage unit 31, and the above-described communication with an expiration date And an identification information management unit 33 that generates identification information. Each data is registered in the contractor storage unit 31 when the use contract is concluded. In addition, as shown in Table 3, the contractor storage unit 31 includes three sets of (identification information of the collective housing server 10, the name of the collective housing B, and the address of the collective housing B).

したがって、外部サーバ３０は、集合住宅サーバ１０からのネットスーパの利用要求を受信すると、識別情報照合部３２において集合住宅サーバ１０の識別情報と契約者記憶部３１とを照合し、契約者記憶部３１に識別情報が登録されていれば、識別情報管理部３３において、有効期限付きの通信用識別情報を生成する。通信用識別情報は、住戸端末２０が外部サーバ３０に接続する際のパスワードとしての役割を持つ通信予約の予約番号であり、住戸端末２０の識別情報（集合住宅サーバ１０の識別情報を含む）および有効期限とともに識別情報管理部３３が記憶する。

Therefore, when the external server 30 receives the request for using the net super from the apartment house server 10, the identification information collating unit 32 collates the identification information of the apartment house server 10 with the contractor storage unit 31, and the contractor storage unit If the identification information is registered in 31, the identification information management unit 33 generates communication identification information with an expiration date. The identification information for communication is a reservation number of a communication reservation having a role as a password when the dwelling unit terminal 20 connects to the external server 30, and includes identification information of the dwelling unit terminal 20 (including identification information of the collective housing server 10) and The identification information management part 33 memorize | stores with an expiration date.

  Thereafter, the external server 30 transmits the communication identification information to the collective housing server 10 that has requested use of the net super (P3), and the collective housing server 10 that has received the communication identification information The identification information for communication is transmitted to the dwelling unit terminal 20 which has made a use request for the net supermarket via the communication path Ls of NT1 (P4).

  In general, since the multi-dwelling server 10 has security measures, as described above, the dwelling unit terminal 20 makes a use request to the external server 30 via the dwelling unit server 10. Since the communication identification information is received from the external server 30 via the apartment house server 10, communication during this period can be performed safely.

  In addition, since a use contract is made in advance between the apartment house server 10 and the external server 30 and there is a trust relationship, the safety of the identification information for communication is guaranteed. In other words, for subsequent communication, even if communication is directly performed between the dwelling unit terminal 20 and the external server 30 by establishing a link using the communication identification information received by the dwelling unit terminal 20, an ID, a password, etc. Since no information flows on the communication path Lt, it is possible to communicate safely without leaking the contents such as individual IDs and passwords to the outside. In actual use, it is necessary to notify the external server 30 of the delivery destination of the product separately.

  In the dwelling unit terminal 20 which has obtained the communication identification information, the switching means 24 selects the high-speed communication interface 26 and thereafter communicates with the external server 30 via the router 13 without passing through the apartment house server 10 (P5). . When communication between the dwelling unit terminal 20 and the external server 30 is performed, communication safety is ensured by using communication identification information. That is, when receiving the communication identification information from the apartment house server 10, the dwelling unit terminal 20 returns a reception response including the communication identification information to the external server 30 (P5). The identification information management unit 33 of the external server 30 compares the communication identification information included in the reception response from the dwelling unit terminal 20 with the stored communication identification information. A service for accepting a net supermarket product order is started (P6, P7). That is, at this point, the dwelling unit terminal 20 logs in to the service of the external server 30.

  As described above, with regard to the process of acquiring the communication identification information that is a real login password, the communication path Ls of the local network NT1 that is guaranteed to be securely communicated by the function of the apartment house server 10 at a low speed. For each service request received from the external server 30 via the communication path Ls, while using the high-speed communication path Lt, when executing a service that performs communication that goes through and increases the amount of communication like an actual product order By using the generated communication identification information with an expiration date, it is not necessary to transmit individual IDs and passwords to the communication path Lt, so that it is possible to perform communication safely. When using the net super, the address and name for each user are separately input at the time of ordering and notified to the external server 30.

  The switching means 24 of the dwelling unit 20 selects the high-speed communication interface 26 triggered by the acquisition of the communication identification information from the external server 30, and switches from the backbone communication interface 25 to the high-speed communication interface 26. It is possible to carry out smoothly. In the dwelling unit terminal 20, when the communication with the external server 30 is terminated, the switching unit 24 returns to the state in which the basic communication interface 25 is selected.

  On the other hand, the external server 30 uses the expiration date of the communication identification information and invalidates the communication identification information when the expiration date is reached, thereby preventing unauthorized access due to leakage of the communication identification information. The expiration date of the communication identification information is a standard processing time until the external server 30 returns the communication identification information and the dwelling unit 20 that has received the communication identification information connects to the external server 30. Is set based on

  In the above-described example, when the communication identification information generated in the external server 30 is transmitted to the apartment house server 10 and the dwelling unit terminal 20, the communication identification information and the expiration date are transmitted. It is good also as a structure which transmits only the identification information for communication, without transmitting.

  Moreover, when the dwelling unit terminal 20 communicates with the external server 30 using the communication identification information, only the communication identification information may be transmitted, but it is desirable to transmit the identification information of the dwelling unit terminal 20 together. . That is, it is desirable to transmit identification information between the transmission source and the transmission destination.

  In the embodiment described above, the switching unit 24, the core communication interface 25, and the high-speed communication interface 26 are provided in the dwelling unit terminal 20, but these configurations can be provided separately from the dwelling unit terminal 20.

(Embodiment 2)
In the first embodiment, when the dwelling unit terminal 20 transmits a use request to the external server 30 that provides a net super service, the housing unit 20 passes through the apartment house server 10, but in this embodiment, as shown in FIG. An example will be described in which the functions of the external server 30 are divided and a service providing server 30a for providing a service and a service management server 30b to be described later are provided. In the present embodiment, the apartment house server 10 transmits a use request to the service providing server 30a via the service management server 30b. The service management server 30b is managed by an administrator different from the administrator of the service providing server 30a.

  In the first embodiment, both the function of providing a service and the function of issuing identification information for communication are provided in the external server 30 managed by a single administrator, whereas in the present embodiment, A service providing server 30a having a function of providing a service and a service management server 30b having a function of issuing communication identification information are separately provided. In addition to the service use request to the service management server 30b, the apartment house server 10 identifies the identification information of the dwelling unit terminal 20, the identification information of the apartment house server 10, and the identification of the service providing server 30a that provides the service. Send information and.

  The service management server 30b provides contract housing information in which the identification information of the housing complex server 10 and the address / name of the housing complex B are associated with each other for the housing complex B for which the service providing server 30a provides a service contract. The contractor storage unit 31 ′ stored in association with the identification information of the providing server 30a, and the identification information collation unit 32 that collates the identification information of the apartment house server 10 received from the apartment house server 10 with the contractor storage unit 31 ′. 'And an identification information management unit 33' for generating identification information for communication with an expiration date.

  In the identification information collation unit 32 ′, the identification information of the apartment house server 10 received from the apartment house server 10 and the identification information of the service providing server 30 a are collated with the contractor storage unit 31 ′, and the apartment house received from the apartment house server 10. When the identification information of the server 10 and the identification information of the service providing server 30a match the contents of the contractor storage unit 31 ', it is determined that the apartment house server 10 is permitted to access the service providing server 30a.

  When the identification information collating unit 32 ′ determines that the apartment house server 10 is permitted to access the service providing server 30a, the identification information managing unit 33 ′ issues and stores the communication identification information, The communication identification information is distributed to the service providing server 30a and the apartment house server 10. The housing server 10 that has received the communication identification information from the service management server 30b transmits the communication identification information to the dwelling unit terminal 20 that has requested use of the service via the communication path Ls of the local network NT1. To do.

  Due to the above-described operation, the dwelling unit terminal 20 and the service providing server 30a have common identification information for communication. Also, the communication providing information issued by the service management server 30b is transmitted to the service providing server 30a, and information such as ID and password is leaked to the communication path Lt because the communication providing information is not directly communicated with the apartment house server 10. Therefore, it is possible to communicate safely.

  In short, the service management server 30b mediates communication between the apartment house server 10 and the service providing server 30a, so that the identification information regarding the apartment house server 10 is notified only to the service management server 30b which is a reliable third party. Is done. Therefore, it is not known to the service providing server 30a which is an unspecified communication partner.
