Abstract

A method and system for transmitting information over a communication network comprising a user device and a server, wherein the user device receives the information from or via this server. The method comprises the step of triggering an interactive session between the server and the user device depending on at least one property of the requested information and evaluating the result of the interactive session. On the basis of the result of the interactive session, it is determined whether and/or in what form the requested information is transmitted to the user device.

Claims

1. A method for transmitting information, over a communication network having a first server and a mobile user device, the method comprising the steps of:

receiving a request, from the mobile user device and at the first server, for an item of information then desired by a user;

retrieving the item of information from its current location;

accessing a user profile for the user or a user device profile for the user device for both delineation of a pre-defined property of the item of information and a limit value associated with the property, the predefined property and the limit value being defined by specific operational characteristics of the mobile device or preferences of the user;

analyzing the item of information so as to determine whether an actual value of the property of the item of information exceeds the limit value;

if the actual value exceeds the limit value, first establishing an interactive session between the first server and the user device during which the first server queries the user, through the user device, by issuing a query to the user device to ascertain, through a user response to the query, whether the user still wants the item of information transmitted to the user device and, if so, whether and how the user wants the information to be modified for transmission to the user device; and

if as reflected in the user response the user still wants to receive the item of information, then transmitting, in response to results of the query as indicated in the user response, the item of information to the user device and, if the user specified such a modification in the user response, in a modified form as then requested by the user.

2. The method recited in claim 1 wherein the item of information is retrieved from a second server, and the first server then evaluates the pre-defined property of the item of information so retrieved.

3. The method recited in claim 1 wherein the item of information or the actual value of the pre-defined property is stored at the first server.

4. The method recited in claim 1 wherein the item of information or the actual value of the pre-defined property is retrieved from a cache associated with the first server.

5. The method recited in claim 1 wherein the user profile or the user device profile is stored on the first server or retrievable by the first server from a profile database.

6. The method recited in claim 5 wherein the user profile or the user device profile is set by the user via either the user device or any other device connectable to the profile database.

7. The method recited in claim 5 wherein the pre-defined property relates to size of the item of information.

8. The method recited in claim 5 wherein the pre-defined property relates to display measurements of the item of information.

9. The method recited in claim 5 wherein the pre-defined property relates to technical requirements for the user device to properly display the item of information.

10. The method recited in claim 1 wherein the establishing step comprises the steps of:

sending a first query from the first server to the user device, the first query being presented to the user; and

receiving, at the first server, a first response from the user device, the first response reflecting a choice made by the user as a result of the first query.

11. The method recited in claim 10 wherein the first query relates to whether the first server should transmit the item of information to the user device.

12. The method recited in claim 11 wherein the transmitting step comprises the step of:

if the first response specifies that the item of information should be transmitted unmodified, transmitting the item of information unmodified from the first server to the user device.

13. The method recited in claim 12 wherein the transmitting step comprises the steps of:

if the first response specifies that the item of information should be transmitted but in a particular modified form, transmitting, to the user device, a second query to the user to ascertain how the user desires the item of information to be modified;

receiving, from the user device and in response to the second query, a second response from the user through which the user has selected a predefined manner through which the item of information is to be modified;

modifying the item of information in the manner specified by the second response so as to yield a modified item of information; and

transmitting the modified item of information to the user device.

14. The method recited in claim 13 wherein the second query specifies various alternate manners through which the item of information can be modified.

15. The method recited in claim 14 wherein the alternate manners comprises modifying size of the item of information, display measurements of the item of information or technical requirements for the user device for properly displaying the item of information.

16. The method recited in claim 10 wherein the establishing step further comprises the step of:

if the first user response reflects that the user does not want the item of information or the second user response reflects that the user has decided not to have the item of information modified, not transmitting the item of information to the user device either in unmodified or modified form.

17. The method recited in claim 10 wherein the first query permits the user to select among various possible responses other than a positive or negative response.

18. The method recited in claim 17 further comprising the step of, where the request for the item of information specifies an information page which is not suitable for the user device, providing the user, through the first query, with an opportunity to request, through the first user response, transmission of an information page which is suitable for the user device.

19. The method recited in claim 1 wherein the item of information comprises information parts and the pre-defined property relates to one or more of the information parts.

20. The method recited in claim 1 wherein the establishing step comprises the step of comparing size of the item of information with a threshold size contained in either the user profile or the user device profile.

21. The method recited in claim 1 wherein the establishing step comprises the step of comparing display measurements of the item of information with details of a display size of the user device specified in either the user profile or the user device profile.

22. The method recited in claim 1 wherein the establishing step comprises the step of comparing format of the item of information with details contained in either the user profile or the user device profile relating to compatibility of the user device to operate with said format.

23. The method recited in claim 1 wherein the user profile or the user device profile comprises details of one or more selected from a group comprising:

threshold size for the item of information, display size of the user device, and technical compatibility of the user device with one or more information formats.

24. The method recited in claim 20 wherein the details of the compatibility of the user device relates to HTML types, ActiveX, Java applets, or Flash.
