Abstract

A method for processing a request from a first terminal to establish a communication session between the first terminal and a second terminal, the first terminal and the second terminal being operable to communicate via a telecommunication network, the method comprising: receiving at the telecommunication network a request from the first terminal to establish a communication session with the second terminal; determining whether the second terminal is available to support the communication session; and if the second terminal is determined not to be available to support the communication session, transmitting to the first terminal the address of a data set corresponding to the second terminal.

Claims

1. A method for processing a request from a first terminal to establish a communication session between the first terminal and a second terminal, the first terminal and the second terminal being operable to communicate via a telecommunication network, the method comprising:

receiving at the telecommunication network a request from the first terminal to establish a communication session with the second terminal;

determining whether the second terminal is available to support the communication session; and

if the second terminal is determined not to be available to support the communication session, transmitting to the first terminal the address of a data set corresponding to the second terminal.

2. A method as claimed in claim 1, comprising the step of, if the second terminal is determined to be available to support the communication session, establishing a communication session between the first terminal and the second terminal.

3. A method as claimed in claim 1 or 2, wherein the data set is a data file of a format in which at least one of a text, audio or video element can be embedded.

4. A method as claimed in claim 3, wherein the data file is formatted in a mark-up language.

5. A method as claimed in claim 4, wherein the address is an address in an address space of a publicly accessible data network.

6. A method as claimed in claim 5, wherein the publicly accessible data network is the internet.

7. A method as claimed in claim 5 or 6, wherein the address is a uniform resource locator.

8. A method as claimed in any preceding claim, comprising the steps of:

transmitting a request for the data set from the first terminal to the address; and

transmitting the data set to the first terminal.

9. A method as claimed in claim 8, wherein the first terminal is configurable to automatically transmit a request for the data set on receiving the address of the data set.

10. A method as claimed in claim 8 or 9, wherein, having received the address of the data set, the first terminal is operable in response to user input to transmit the request for the data set.

11. A method as claimed in any of claims 8 to 10, comprising the step of the first terminal presenting content of the data set to a user of the first terminal.

12. A method as claimed in any preceding claim, wherein the communication session is a voice communication session.

13. A method as claimed in any preceding claim, wherein the first terminal is configured to receive the data set over a data communication link.

14. A method as claimed in any preceding claim, wherein the address of the data set is transmitted to the second terminal in conjunction with an indication that the communication session cannot be established.

15. A method as claimed in any preceding claim, wherein the address of the data set is transmitted to the first terminal in a SIP message.

16. A method as claimed in any preceding claim, wherein said data set is selected from a plurality of data sets by means of the first terminal.

17. A method as claimed in any preceding claim, wherein said data set is selected from a plurality of data sets based on information associated with the first terminal.

18. A method as claimed in claim 17, wherein the selection is based on the identity of the user of the first terminal.

19. A SIP server of a communication network, the SIP server being configured to process SIP messages to establish communication sessions between terminals operable to communicate via the network, and to, in the event that a request from a first terminal to establish a communication session with a second terminal cannot be satisfied, transmit to the first terminal the address of a data set corresponding to the second terminal.

20. A SIP server as claimed in claim 19, wherein the data set is a data file of a format in which a text, audio or video element can be embedded.

21. A SIP server as claimed in claim 20, wherein the data file is formatted in a mark-up language.

22. A method for processing a request from a first terminal to establish a communication session between the first terminal and a second terminal, the first terminal and the second terminal being operable to communicate via a telecommunication network, the method comprising:

storing a data set corresponding to the second terminal, the data set being formatted in a mark-up language and having a media file embedded in it;

receiving at the telecommunication network a request from the first terminal to establish a communication session with the second terminal;

determining whether the second terminal is available to support the communication session; and

if the second terminal is determined not to be available to support the communication session, transmitting the data set to the second terminal.

23. A method as claimed in claim 22, comprising the step of, if the second terminal is determined to be available to support the communication session, establishing a communication session between the first terminal and the second terminal.

24. A method as claimed in claim 22 or 23, wherein the media file represents a text, audio or video element.

25. A method as claimed in any of claims 22 to 24, wherein the data file is formatted in HTML or XML.

26. A method as claimed in any of claims 22 to 25, comprising the step of the first terminal presenting content of the data set to a user of the first terminal.

27. A method as claimed in any of claims 22 to 26, wherein the communication session is a voice communication session.

28. A method as claimed in any of claims 22 to 27, wherein the data set is transmitted to the first terminal over a data communication link.

29. A method as claimed in any of claims 22 to 28, wherein the data set is transmitted to the second terminal in conjunction with an indication that the communication session cannot be established.

30. A method as claimed in any of claims 22 to 29, wherein the data set is transmitted to the first terminal in a SIP message.

31. A SIP server of a communication network, the SIP server being configured to process SIP messages to establish communication sessions between terminals operable to communicate via the network, and to, in the event that a request from a first terminal to establish a communication session with a second terminal cannot be satisfied, transmit to the first terminal a data set corresponding to the second terminal, the data set being formatted in a mark-up language and having a media file embedded in it.

32. A SIP server as claimed in claim 31, wherein the media file represents a text, audio or video element.

33. A SIP server as claimed in claim 32 or 33, wherein the data file is formatted in HTML.
