Internet server apparatus and program causing a server apparatus to implement functions of preparation processing for direct connection of an appliance in a private network and a mobile terminal outside the private network
View Patent ↗A server apparatus, a mobile terminal, an electric appliance, a communication system, a communication method and a program for notifying a mobile terminal user in the open of the cause of a failure of P2P connection. In a communication system, an electric appliance ( 101 ), a server apparatus ( 103 ) and a mobile terminal ( 105 ) each detect a failure in preparation for P2P connection between the electric appliance ( 101 ) and the mobile terminal ( 105 ). When the electric appliance ( 101 ) detects the failure, it notifies the mobile terminal ( 105 ) of the failure via the server apparatus ( 103 ). When the server apparatus ( 103 ) detects the failure, it notifies the mobile terminal ( 105 ) of the failure. The mobile terminal ( 105 ) notifies the user of the failure detected by the mobile terminal itself or of the failure notified of by the server apparatus ( 103 ).
1. An Internet server apparatus that performs preparation processing for direct connection between an electrical appliance inside a private network connected to the Internet, and a mobile terminal outside the private network, the server apparatus comprising:
a detecting section that detects a failure in the preparation processing for direct connection between the electrical appliance and the mobile terminal;
a reporting section that reports information showing the failure detected by the detecting section, to the mobile terminal;
a certificate issuing section that, when a direct connection between the electrical appliance and the mobile terminal has succeeded, issues an electronic certificate that certifies that direct connection to the electrical appliance and the mobile terminal is possible; and
a transmitting section that transmits the certificate issued by the certificate issuing section to the mobile terminal.
2. The server apparatus according to claim 1 , wherein the detecting section detects the failure in the preparation processing for direct connection between the electrical appliance and the mobile terminal by receiving a report showing a failure of the electrical appliance in controlling settings of a NAT router provided in the private network.
3. The server apparatus according to claim 1 , further comprising a receiving section that receives setting information and address information of the NAT router provided in the private network from the electrical appliance,
wherein, when the server apparatus attempts to connect to the electrical appliance based on the setting information and address information of the NAT router received by the receiving section, the detecting section detects a failure of the connection.
4. The server apparatus according to claim 1 , further comprising a storage section that stores setting information and address information of a NAT router provided in the private network, as connection information for the electrical appliance,
wherein the detecting section detects a failure of the storage section in acquiring the connection information by confirming that the connection information for an electrical appliance to which connection from the mobile terminal is desired, is not stored in the storage section.
5. The server apparatus according to claim 1 , further comprising:
a status managing section that receives from the electrical appliance a report of successful direct connection to the mobile terminal and acquires from the mobile terminal a report of successful direct connection to the electrical appliance, wherein:
the certificate issuing section determines that the direct connection between the electrical appliance and the mobile terminal has succeeded when the status managing section acquires the reports of successful direct connection from the electrical appliance and the mobile terminal.
6. The server apparatus according to claim 5 , further comprising:
a check section that checks whether the certificate transmitted from the mobile terminal is issued by the server apparatus and whether direct connection to an electrical appliance to which connection from the mobile terminal is desired, is possible; and
a user data managing section that, when the check section decides that the certificate is issued by the server apparatus and that direct connection to the electrical appliance to which connection from the mobile terminal is desired, is possible, registers user information of a user of the mobile terminal.
7. A non-transitory computer-readable storage medium having stored thereon a computer implemented program that causes a computer in a server apparatus to implement functions of:
a detecting section that detects a failure in preparation processing for direct connection between an electrical appliance inside a private network connected to the Internet, and a mobile terminal outside the private network;
a reporting section that reports information showing the failure detected by the detecting section to the mobile terminal;
a certificate issuing section that, when a direct connection between the electrical appliance and the mobile terminal has succeeded, issues an electronic certificate that certifies that direct connection to the electrical appliance and the mobile terminal is possible; and
a transmitting section that transmits the certificate issued by the certificate issuing section to the mobile terminal.
8. A method for an Internet server apparatus that performs preparation processing for direct connection between an electrical appliance inside a private network connected to the Internet, and a mobile terminal outside the private network, the method comprising steps of:
detecting a failure in the preparation processing for direct connection between the electrical appliance and the mobile terminal;
reporting, information showing the detected failure, to the mobile terminal;
issuing, when a direct connection between the electrical appliance and the mobile terminal has succeeded, an electronic certificate that certifies that direct connection to the electrical appliance and the mobile terminal is possible; and
transmitting the issued certificate to the mobile terminal.
