Abstract

Provided are a universal plug and play (UPnP) method and an apparatus thereof to provide remote access service, where the method includes receiving external inputs of an identifier of a remote access server (RAS) to generate a credential and a session initiation protocol (SIP) identifier of the RAS, generating a payload of a SIP packet written in extensible markup language (XML), which includes a credential ID generated based on the identifier of the RAS and remote access transport agent (RATA) capability information, and transmitting the SIP packet to the RAS identified by the SIP identifier, where the payload of the SIP packet includes multipurpose internet mail extensions (MIME)-type information to be identified as information used to provide remote access service.

Claims

1. A communication method of a universal plug and play (UPnP) remote access client (RAC) providing remote access service, the communication method comprising:

receiving external inputs of an identifier of a UPnP remote access server (RAS) to generate a credential, and a session initiation protocol (SIP) identifier of the RAS;

generating a payload of a first SIP packet, which is described in extensible markup language (XML) format, and includes a credential identifier (ID) generated based on the identifier of the RAS and remote access transport agent (RATA) capability information; and

transmitting the first SIP packet to the RAS identified by the SIP identifier,

wherein the payload of the first SIP packet includes multipurpose internet mail extensions (MIME)-type information such that the payload is identified as information to provide remote access service.

2. The communication method of claim 1, further comprising:

receiving a second SIP packet including a RATA profile, which is for remote access and is described in XML format in the form of a payload of the second SIP packet, from the RAS; and

extracting the payload from the second SIP packet including the RATA profile for remote access.

3. The communication method of claim 1, wherein the payload of the first SIP packet is a multipart-payload comprising:

a first payload part containing information used to establish a SIP session between the RAS and the RAC; and

a second payload part containing the credential ID and the RATA capability information of the RAC.

4. The communication method of claim 3, wherein the second payload part is described in encrypted XML and includes security service for MIME-type information such that the second payload part is identified as information used to provide encrypted remote access.

5. The communication method of claim 3, wherein the first payload part is described in session description protocol format, and the second payload part is described in XML format.

6. The communication method of claim 3, wherein multipart-content type information, which is used to identify that the first SIP packet includes the multipart-payload, is included within a header of the first SIP packet.

7. The communication method of claim 1, wherein the first SIP packet is a SIP invite packet or a SIP options packet.

21. A computer readable recording medium having recorded thereon a computer program causing a computer to execute the method of claim 1.

8. A communication method of a universal plug and play (UPnP) remote access server (RAS) providing remote access service, the communication method comprising:

receiving a first session initiation protocol (SIP) packet a credential identifier (ID) and remote access transport agent (RATA) capability information in the form of a payload of the first SIP packet, from the remote access client (RAC), the payload being described in extensible markup language (XML) format;

extracting the payload from the first SIP packet;

transmitting the credential ID and the RATA capability information to a management console which has subscribed to receive events in advance,

wherein the payload of the first SIP packet includes multipurpose internet mail extensions (MIME)-type information such that the payload is identified as information to provide remote access service.

9. The communication method of claim 8, further comprising:

receiving RATA profiles with regard to the RAC and the RAS from the management console;

generating a payload of a second SIP packet, which is described in XML format and includes a RATA profile with regard to the RAC; and

transmitting the second SIP packet to the RAC.

10. The communication method of claim 9, wherein the payload of the second SIP packet is a multipart-payload comprising:

a first payload part containing information used to establish a SIP session between the RAS and the RAC; and

a second payload part containing the RATA profile with regard to the RAC.

11. The communication method of claim 10, wherein the second payload part is described in encrypted XML and includes security service for MIME (S-MIME)-type information such that the second payload part is identified as encrypted information used to provide remote access.

12. The communication method of claim 10, wherein the first payload part is described in session description protocol format, and the second payload part is described in XML format.

13. The communication method of claim 10, wherein multipart-content type information, which is used to identify that the SIP packet includes the multipart-payload, is included within a header of the SIP packet.

14. The communication method of claim 8, wherein the first SIP packet is a SIP invite packet or a SIP options packet.

15. A universal plug and play (UPnP) remote access client (RAC) to provide remote access service, the UPnP RAC comprising:

a user interface unit receiving external inputs of an identifier of a UPnP remote access server (RAS) to generate a credential and a session initiation protocol (SIP) identifier of the RAS;

a SIP payload generating unit generating a payload of a first SIP packet, which is described in extensible markup language (XML), and includes a credential identifier (ID) generated based on the identifier of the RAS and remote access transport agent (RATA) capability information; and

a SIP packet transmitting unit transmitting the first SIP packet to the RAS identified by the SIP identifier,

wherein the payload of the first SIP packet includes multipurpose internet mail extensions (MIME)-type information such that the payload is identified as information used to provide remote access service.

16. The UPnP RAC of claim 15, further comprising:

a SIP packet receiving unit receiving a second SIP packet, which includes a RATA profile described in XML format for remote access, in the form of a payload of the second SIP packet, from the RAS; and

a SIP payload extracting unit extracting the payload from the second SIP packet.

17. The UPnP RAC of claim 15, wherein the payload of the first SIP packet is a multipart-payload comprising:

a first payload part containing information used to establish a SIP session between the RAS and the RAC; and

a second payload part containing the credential ID and the RATA capability information of the RAC.

18. A universal plug and play (UPnP) remote access server (RAS) to provide remote access service, the UPnP RAS comprising:

a session initiation protocol (SIP) packet receiving unit receiving a first SIP packet including a credential identifier (ID) described in extensive markup language (XML) format and remote access transport agent (RATA) capability information in the form of a payload of the first SIP packet from a UPnP remote access client (RAC);

a SIP payload extracting unit extracting the payload from the first SIP packet; and

a management console transmitting interface transmitting the credential ID and the RATA capability information to a management console subscribed to receive events in advance,

wherein the payload of the first SIP packet includes multipurpose internet mail extensions (MIME)-type information such that the payload is identified as information used to provide remote access service.

19. The UPnP RAS of claim 18, further comprising:

a management console receiving interface receiving RATA profiles with regard to the RAC and the RAS from the management console;

a SIP payload generating unit generating a payload of a second SIP packet, which is described in XML format and includes a RATA profile with regard to the RAC; and

a SIP packet transmitting unit transmitting the second SIP packet to the RAC.

20. The UPnP RAS of claim 19, wherein the payload of the second SIP packet is a multipart-payload comprising:
