By setting the data communication network 10 to map to the corresponding closed network, the function for constructing the closed network corresponding to the community and the user terminal of the user and the closed network are used for the community. A secure VPN tunnel.

[Community communication network operation]
Next, the operation of the community communication network of the present invention will be described with reference to FIG. FIG. 2 is a sequence diagram showing a community subscription accepting operation of the community communication network according to the embodiment of the present invention.
The community communication network NW executes the community subscription acceptance operation of FIG. 2 in response to a community subscription request from the user terminal. Here, a case will be described as an example in which a virtual account for community A used by the user is generated and acceptance is accepted in response to a subscription request to the community A from the user terminal 31.

When a user wants to newly join the community A, the user terminal 31 sends a subscription request including a user ID unique to the user himself / herself and account attribute information characterizing the user used in the community A to the community A in advance. It transmits to the community manager terminal 41 matched (step 100).
The community manager terminal 41 displays the contents of the subscription request from the user terminal 31 on the screen, and transmits a matching request for the attribute information of the user to the community management server 20 in response to the matching request operation of the community manager thereafter. (Step 101).

In response to the collation request from the community manager terminal 41, the user information management unit 23 of the community management server 20 acquires the personal information of the user from the user information DB 21 based on the user ID included in the collation request (step 102). . Moreover, the subscription conditions of the said community A are acquired from community information DB22 (step 103).
Then, the personal information of the user and the account attribute information included in the verification request are verified (step 104), and the verification result is returned to the community manager terminal 41 (step 105).

  At this time, the user information management unit 23 searches the community information DB 22, and when a subscription condition is set for the community, the user information management unit 23 acquires the subscription condition and compares it with the personal information and the account attribute information. The user confirms whether or not the conditions for joining the community are acceptable, and returns it in the verification result.

  FIG. 3 is a configuration example of personal information. FIG. 4 is a configuration example of account attribute information. As shown in FIG. 3, personal information includes information such as “name”, “address”, “age”, and the like indicating the actual personality of the user associated with the “user ID” unique to the user. It is input at the time of user registration in the communication network NW and registered in the user information DB 21. As shown in FIG. 4, the account attribute information is a part of the personal information of the user associated with “nickname” which is user identification information in the community, in this case “name”, “address”, “age” ”And information such as“ hobby ”indicating attribute information included in the community subscription request from the user terminal.

  The user information management unit 23 compares the personal information and the account attribute information for each item in response to the collation request. In the case of FIG. 3 and FIG. 4, the “age” applied by the account attribute information at the time of the subscription request from the user is different from the personal information. Therefore, the collation result is determined to be “collation failure”, and the community administrator is notified that the account attribute information has been misrepresented by the user. At this time, there may be a mistake in inputting account attribute information, but here, it is determined that the collation has failed as in the case of misrepresentation.

  In addition, when a subscription condition is set for the community, the user information management unit 23 performs collation in consideration of the subscription condition. FIG. 5 is a configuration example of community subscription conditions. The conditions for joining the community are set for each item of the account attribute information. In the example of FIG. 5, “name” is “real name only”, and omission and provisional names are not permitted. Further, “address” can be omitted from “prefecture”, and “age” is limited to “20 years or older”.

Here, in the account attribute information of FIG. 4, although each item conforms to the subscription condition, the actual “age” by personal information is “18”, and the subscription condition is not satisfied. It is determined.
If the actual “age” according to the personal information is “25” and the “age” requested by the account attribute information is “20”, the personal information does not match the account attribute information. Both of them satisfy the joining condition of “20 years or older”, so it is determined that the joining condition has passed. In such a case, the user information management unit 23 may determine that the subscription is permitted, and may notify the community manager of the fact as a verification result.

The community manager terminal 41 displays the collation result returned from the community management server 20 on the screen, and the community manager determines whether or not the user is allowed to join based on the collation result (step 106).
Thereafter, the community manager terminal 41 transmits a request for registering a virtual account related to the user to the community management server 20 in response to a registration request operation by the community manager according to the determination of the subscription permission (step 110).

In response to this registration request, the community management unit 24 of the community management server 20 acquires personal information of the user from the user information DB 21 based on the user ID specified in the registration request, and the account included in the subscription request The attribute information is acquired, and a virtual account of the user used in the community A is generated based on the personal information and the account attribute information (step 111).
The virtual account may be composed of only part or all of the personal information of the user, or may be composed only of attribute information included in the subscription request. Further, information indicating information items necessary as account attribute information of a virtual account may be registered in the community information DB as virtual account generation information, for example. The virtual account generation information may be set in common for all communities, or may be set by a community administrator for each community.

After generating the virtual account in this way, the community management unit 24 outputs the virtual account registration instruction to the user information DB 21 (step 112), and the user information DB 21 indicates the virtual account accordingly. Account attribute information is registered (step 113).
In addition, the community management unit 24 outputs a member information registration instruction regarding the virtual account to the community information DB 22 (step 114), and the community information DB 22 is associated with the community ID of the community A accordingly, A set of the user ID and nickname of the user included in the attribute information is registered in the community information DB 22 (step 115).

FIG. 6 is a configuration example of member information. Here, for each community ID unique to a community, a set of a user ID and a nickname of a user who has joined the community is registered. At this time, the nickname may be unique within the community, and the same nickname may be used between different communities.
For such a nickname duplication check, for example, the community management unit 24 refers to the community information DB 22 at the time of virtual account generation, and the nickname designated by the attribute information included in the community subscription request from the user terminal is within the community. What is necessary is just to confirm whether it is unique. If the specified nickname is duplicated, the user may be prompted to input the nickname again or the community subscription acceptance process may be interrupted.

  The community management unit 24 registers the members in the community information DB 22 in this way, and then controls the community control unit 25 to reconstruct the community A based on the updated member information of the community A (step 116). ).

The community control unit 25 uses the virtual account from the user terminal 31 for the authentication function of the logical edge router corresponding to the user terminal 31 in the data communication network 10 in response to the restructuring instruction from the community management unit 24. A new virtual account is set by setting authentication information for authenticating login to the community A and setting a secure VPN tunnel between the logical edge router and the user terminal 31.
Further, the community control unit 25 changes the routing table of each logical edge router that constitutes the closed network of the community A in the data communication network 10, and secures VPN between the logical edge router corresponding to the user terminal. By setting each tunnel, the closed network 30A on the IP-VPN 30 is reconstructed.

  In this way, in response to the community subscription request from the user terminal, a virtual account unique to the user's community A is generated, and the correspondence between the new virtual account based on the member information of the community A and the community, The connection relationship between the virtual accounts belonging to the community A is mapped to the connection relationship between the logical edge routers corresponding to the user terminals, and the community A is reconstructed.

After the community A is reconstructed, the community management unit 24 notifies the community manager terminal 41 of the registration completion of the virtual account of the user (step 120), and a series of community subscription acceptance operations in the community communication network is completed. To do.
The community manager terminal 41 displays this registration completion on the screen, and notifies the user terminal 31 of the subscription completion for the community in response to a registration completion notification instruction from the community manager thereafter (step 121). The completion of the subscription is displayed on the screen to notify the user.

  Thereafter, in response to a user operation corresponding to confirmation of the completion of the subscription, the user terminal 31 accesses the closed network of the community via the logical edge router based on the newly generated virtual account. Set a communication control unit specific to the virtual account. Here, various information necessary to connect to the desired community using the virtual account and perform community communication, such as the nickname of the virtual account, the community, and the password for login authentication authentication at the logical edge router, is set. The
