Abstract

A method for providing state-dependant information to a terminal operable in communication with a communication network including a server unit, the method comprising: receiving at the server unit a request from the terminal for data; determining the state of the terminal by means of the server unit; requesting by means of the server unit state-dependent data dependant on the state of the terminal and corresponding to the requested data, the server unit transmitting a request for the state-dependent data that includes an indication of the determined state of the terminal; receiving at the server unit the state-dependant data; and transmitting the state-dependant data to the terminal.

Claims

1. A method for providing state-dependant information to a terminal operable in communication with a communication network including a server unit, the method comprising:

receiving at the server unit a request from the terminal for data;

determining the state of the terminal by means of the server unit;

requesting by means of the server unit state-dependant data dependent on the state of the terminal and corresponding to the requested data, the server unit transmitting a request for the state-dependent data that includes an indication of the determined state of the terminal, the said requesting step being performed in response to receiving at the serer unit primary data including an indication of the availability of corresponding state-dependant data dependant on a state of a terminal;

receiving at the server unit the state-dependant data; and

transmitting the state-dependant data to the terminal.

2. A method as claimed in claim 1, wherein the said state of the terminal is the location of the terminal.

3. A method as claimed in claim 2, wherein the network includes a location determining unit, and the step of determining the said state of the terminal comprises determining the location of the terminal by means of the location determining unit.

4. A method as claimed in claim 3, wherein the location determining unit determines the location of the terminal by means of characteristics of radio communications between the terminal and the network.

5. A method as claimed in claim 4, wherein the said characteristics are timing differences.

6. A method as claimed in any of claims 3 to 5, comprising the step of the location determining unit communicating the determined location to the server unit.

7. A method as claimed in any preceding claim, wherein the server unit is a proxy unit.

8. A method as claimed in any preceding claim, wherein the server unit is capable of caching received data for transmission to other terminals.

9. A method as claimed in any preceding claim, comprising the step of the terminal presenting the state-dependant data to a user.

10. A method as claimed in any preceding claim, wherein at least one of the primary data and the state-dependant date is world-wide web (WWW) data.

11. A method as claimed In any preceding claim, wherein at least one of the primary data and the state-dependant data is conveyed to the server unit by means of hypertext transfer protocol (HTTP).

12. A method as, claimed in any preceding claim, wherein the state-dependant data is conveyed to the terminal by means of general packet radio service (GPRS).

13. A method as claimed in claim 12, therein the server unit is located at a global general packet radio service serving node (GGSN).

14. A method as claimed in any preceding claim, wherein the primary data and the state-dependant data are communicated to the server unit via the internet.

15. A method as claimed in any preceding claim, wherein the server unit requests the state-dependant data by means of a hypertext transfer protocol (HTTP) page request.

16. A method as claimed in claim 15, wherein the hypertext transfer protocol (HTTP) page request includes data indictive of the location of the terminal.

17. A method as claimed in any preceding claim, comprising the step of the terminal requesting the primary data.

18. A method as claimed in claim 17, wherein the terminal requests the primary data by way of the server unit.

19. A method as claimed in any preceding claim, wherein the network is a mobile communication network.

20. A method as claimed in any preceding claim, wherein the terminal is a mobile station.

21. A method as claimed in claim 20, wherein the terminal is a mobile telephone.

22. A method as claimed in any preceding claim, wherein the terminal is mobile.

23. A method as claimed in, any preceding claim, comprising the steps of receiving at the server unit data having an associated data identifier, comparing at least part of the data identifier with the contents of an identifier database, and performing the said step of requesting state-dependant data in response to the result of that comparison.

24. A method as claimed in claim 23, wherein the data having an associated data identifier data is data specified in the said request for data.

25. A method as claimed in claim 23 or 24, wherein the data identifier is a universal resource locator.

26. A method as claimed in any preceding claim, wherein the step of requesting the state-dependant data comprises requesting the state-dependant data from a data server.

27. A method as claimed in claim 26 as dependant on any of claims 23 to 25, wherein the identity of the data server is specified in the data identifier.

28. A method as claimed in claim 26 or 27, wherein the step of requesting the state-dependant data comprises transmitting to the data server a request for the state-dependant data, the request including information indicative of the location of the terminal.

29. A method as claimed in any preceding claim, wherein the state dependant data is wireless application protocol content.

30. A communication network comprising a server unit adapted to receive primary data, detect within the primary data an indication of the availability of corresponding state-dependant data dependant on a state of a terminal, determine the said state of the terminal;

request state-dependant data dependant on the determined state of the terminal, receive the state-dependant data and transmit the state-dependant data to the terminal.
