UPnP apparatus and method for providing remote access service

A communication computer implemented method of a universal plug and play (UPnP) remote access server (RAS) device for providing a remote access service, the method comprising:

• receiving an IP based application protocol packet including a credential ID and remote access transport agent (RATA) capability information from a remote access client (RAC) device;
• decapsulating an extensible authentication protocol (EAP) packet from the received IP based application protocol packet;
• extracting WiFi protected setup (WPS) messages including the credential ID and the RATA capability information from the EAP packet;
• transmitting the credential ID and the RATA capability information to a management console device that subscribes to an event in advance;
• receiving RATA profiles with regard to the RAC device and the RAS device from the management console device;
• and
• establishing the RATA profiles with regard to the RAS device in the RAS device,
• generating WPS messages including the RATA profiles with regard to the RAC device;
• encapsulating the EAP packet including the WPS messages in the IP based application protocol packet;
• and
• transmitting the IP based application protocol packet to the RAC device.

A universal plug and play (UPnP) remote access client (RAC) device for providing a remote access service, the device comprising:

• a user interfacing unit which receives product identification number (PIN) information that is an identifier provided to a remote access server (RAS) device when manufactured and a URL of the RAS device from the outside;
• a WiFi protected setup (WPS) message generating unit which generates WPS messages including a credential ID and remote access transport agent (RATA) capability information, which are generated based on the PIN information;
• a protocol encapsulation unit which encapsulates an extensible authentication protocol (EAP) packet including the WPS messages as an IP based application protocol packet;
• a transmission unit which transmits the IP based application protocol packet to the RAS device,
• a receiving unit which receives the IP based application protocol packet including RATA profiles for remote access;
• a protocol decapsulating unit which decapsulates the EAP packet from the received IP based application protocol packet;
• a WPS message extracting unit which extracts the WPS messages including the RATA profiles for the remote access from the EAP packet;
• and
• a RATA profile configuring unit which establishes the RATA profiles for the remote access in the RAS device.
