First Claim
Patent Images
1. A connection support apparatus comprising:
- a control unit configured to perform an authentication of a user terminal based on user authentication information received from the user terminal, and to send a control request added with a random number to a gateway apparatus to open a closed port of the gateway apparatus in order to permit a connection from the user terminal for which the authentication succeeds; and
a communication unit configured to provide the user terminal with connection information, added with the random number, and used for connecting the user terminal to the gateway apparatus when the control unit receives a response to the control request from the gateway apparatus, whereinthe control unit adds the random number, an address list of address identifiers held by one or more other gateway apparatuses through which the user terminal communicates, and an application identifier to the control request when an address identifier of the user terminal is not unique.

Abstract
A problem is to provide a connection support apparatus and a gateway apparatus in which management of information is easy and remote access from a user terminal to the gateway apparatus can be performed easily and securely, and the problem is solved by including a control unit configured to perform control on a gateway apparatus to which a user apparatus connects so as to permit connection from the user apparatus for which authentication succeeds; and a communication unit configured to provide the user terminal with connection information used for connecting to the gateway apparatus.

12. A gateway apparatus comprising:
-
a setting unit configured to receive a control request added with a random number from a connection support apparatus, and to make settings for providing a user terminal for which an authentication in the connection support apparatus succeeds with a connection permission; and a communication unit configured to send a response to the control request to the connection support apparatus, and to open a closed port of the gateway apparatus in order to permit a connection from the user terminal provided with the connection permission to the gateway apparatus based on a comparison of the random number included in the control request received from the connection support apparatus and the random number received from the user terminal, wherein the setting unit makes settings for providing the user terminal with the connection permission according to the random number, an address list of address identifiers held by one or more other gateway apparatuses through which the user terminal communicates, and an application identifier that are included in the control request from the connection support apparatus when an address identifier of the user terminal is not unique. - View Dependent Claims (13, 14)

15. A connection method to connect a user terminal and a gateway apparatus using a connection support apparatus, comprising:
-
performing, by the connection support apparatus, an authentication of a user terminal based on user authentication information received from the user terminal; sending, by the connection support apparatus to the gateway apparatus, a control request added with a random number to open a closed port of the gateway apparatus in order to permit a connection from the user terminal for which the authentication succeeds; and providing, by the connection support apparatus to the user terminal, connection information added with the random number and used for connecting the user terminal to the gateway apparatus when a response is received from the gateway apparatus in response to the control request sent to the gateway apparatus by the sending, wherein the control request further includes, when an address identifier of the user terminal is not unique, an address list of address identifiers held by one or more other gateway apparatuses through which the user terminal communicates and an application identifier.
