Abstract

An electronic device is operated by establishing a communication session between the electronic device and a requesting device using Session Initiation Protocol (SIP), providing an Internet Protocol (IP) address for the electronic device to the requesting device using the SIP, receiving a request addressed to the electronic device using the IP address from the requesting device, and conveying the Web service to the requesting device responsive to receiving the request.

Claims

1. A method of operating an electronic device to provide a Web service, comprising:

establishing a communication session between the electronic device and a requesting device using Session Initiation Protocol (SIP);

negotiating the communication session as a connection to a Web server using the SIP;

providing an Internet Protocol (IP) address for the electronic device to the requesting device using the SIP;

receiving a request addressed to the electronic device using the IP address from the requesting device; and

conveying the Web service to the requesting device responsive to receiving the request.

2. The method of claim 1, wherein establishing the communication session comprises establishing the communication session over an IP Multimedia Subsystem (IMS) network.

3. The method of claim 2, further comprising:

registering a profile associated with the electronic device with a Home Subscriber Server (HSS) database in the IMS network, the profile comprising a SIP address for the electronic device for use in completing a SIP call from the requesting device to the electronic device.

4. The method of claim 1, further comprising:

receiving a SIP invite message that comprises a Session Description Protocol (SDP) portion that indicates a request to access the Web service during the communication session.

5. The method of claim 4, wherein the SDP portion comprises a media description field (m=) that contains a media subfield set to application and a format subfield (fmt) set to HyperText Transfer Protocol (HTTP).

6. The method of claim 5, wherein the SDP portion further comprises an attribute field (a=) that contains a Web server attribute to indicate that HTTP is used to access the Web service.

7. The method of claim 1, wherein the electronic device is a mobile terminal.

8. A computer program product comprising computer-readable program code embodied on a computer-readable medium, the computer readable program code being configured to carry out the method of claim 1.

9. An electronic device, comprising:

a Web server; and

a communication module that is configured to establish a communication session between the electronic device and a requesting device using Session Initiation Protocol (SIP);

to negotiate the communication session as a connection to the Web server using the SIP and to provide an Internet Protocol (IP) address for the electronic device to the requesting device using the SIP;

wherein the Web server is configured to receive a request addressed to the electronic device using the IP address from the requesting device and to convey the Web service to the requesting device responsive to receiving the request.

10. The electronic device of claim 9, wherein the communication module is further configured to establish the communication session over an IP Multimedia Subsystem (IMS) network.

11. The electronic device of claim 10, wherein the communication module is further configured to register a profile associated with the electronic device with a Home Subscriber Server (HSS) database in the IMS network, the profile comprising a SIP address for the electronic device for use in completing a SIP call from the requesting device to the electronic device.

12. The electronic device of claim 9, wherein the communication module is further configured to receive a SIP invite message that comprises a Session Description Protocol (SDP) portion that indicates a request to access the Web service during the communication session.

13. The electronic device of claim 12, wherein the SDP portion comprises a media description field (m=) that contains a media subfield set to application and a format subfield (fmt) set to HyperText Transfer Protocol (HTTP).

14. The electronic device of claim 13, wherein the SDP portion further comprises an attribute field (a=) that contains a Web server attribute to indicate that HTTP is used to access the Web service.

15. The electronic device of claim 9, wherein the electronic device is a mobile terminal.

16. A method of operating a communication network, comprising:

using Session Initiation Protocol (SIP) to notify a first electronic device that a second electronic device, which does not have a public Internet Protocol (IP) address, has a Web server;

wherein using the SIP to notify the first electronic device that the second electronic device has the Web server comprises using SIP to provide an IP address for the second electronic device to the first electronic device; and

wherein the second electronic device is a mobile terminal.

17. The method of claim 16, further comprising:

sending a request for a Web service from the first electronic device to the Web server at the second electronic device using the IP address of the second electronic device; and

conveying the Web service from the second electronic device to the first electronic device responsive to receive the request at the second electronic device.

18. The method of claim 17, wherein the communication network is an IP Multimedia Subsystem (IMS) network.

19. The method of claim 18, further comprising:

registering a profile associated with the second electronic device with a Home Subscriber Server (HSS) database in the IMS network, the profile comprising a SIP address for the second electronic device for use in completing a SIP call from the first electronic device to the second electronic device.
