Abstract

The invention pertains to a method, a system and an agent for sending information over a communication network. In the vicinity of a server in the communication network, there is an agent functionality that helps serve one or more clients or users by providing relevant information from a cache containing up-to-date information. The agent can be operated by the user and can also learn the usage behavior of the client.

Claims

1. Method for sending information over a communication network comprising at least one server and at least one client, the server comprising an agent functionality, the method comprising the following steps:

maintaining by the agent of a cache containing up-to-date information;

determining, with the help of the agent, of which up-to-date information is relevant to the client;

sending by the agent to the client of the relevant information over the communication network at an at least suitable time.

2. Method according to claim 1 in which the relevant information contained in the up-to-date information is determined by application of at least one usage profile.

3. Method according to claim 2 in which the relevant information consists of at least an information page and/or parts of the information page defined by the usage profile.

4. Method according to claim 2 in which the usage profile also contains data about a device that incorporates the client, and the agent, when sending relevant information, sends such relevant information to the client of the device in a way appropriate to the device.

5. Method according to claim 2 in which a user of a device that contains the client generates the usage profile.

6. Method according to claim 5 in which the user creates, modifies and/or adds to the usage profile via a device other than the device that contains the client and/or via another network by means of which contact can be established with the agent.

7. Method according to claim 1 in which the communication network contains a large number of clients and the agent combines the usage profiles belonging to at least some of those clients.

8. Method according to claim 1 in which the relevant information is compressed before being sent over the communication network.

9. Method according to claim 7 in which the agent determines whether the relevant information will be sent to the clients through application of multicast techniques.

10. Method according to claim 1, in which the agent uses at least one parameter to determine which action must be executed.

11. Method according to claim 10 in which the parameter indicates the load on at least one part of the communication network and the agent determines, based on the parameter, a suitable time for sending the relevant information.

12. Method according to claim 11 in which the agent indicates which information will be sent, given a certain load on the communication network.

13. Method according to claim 12 in which in the case of a high load on the communication network, only fast-ageing information will be sent, and in the case of a low load on the communication network also information that ages more slowly will be sent.

14. Method according to claim 10 in which the parameter concerns a time at which the client usually retrieves relevant information and the agent determines, based on this parameter, the suitable time for sending the relevant information.

15. Method according to claim 14 in which the agent indicates which information will be sent to the client at which usual time.

16. Method according to claim 10 in which the parameter concerns a place where the relevant information can be important to the user and the agent determines, based on this parameter, the suitable time for sending the relevant information.

17. Method according to claim 10, in which the agent, when sending the information over the communication network, also makes allowance for the capabilities of the device of the user of the client concerned.

18. Method according to claim 1, in which the agent learns the behavioral pattern of the user.

19. Method according to claim 18 in which the learning of the user'"'"'s behavioral pattern occurs because the client communicates the user'"'"'s behavior to the agent.

20. Method according to claim 1 in which the agent does not bundle the relevant information for the client until the relevant information is sent to the client.

21. System for sending information over a communication network comprising at least:

a server equipped with a server cache;

a client;

an agent functionality at the server that is arranged to maintain up-to-date information in the server cache, determine information relevant to the client and send the relevant information over the communication network at an at least suitable time.

22. System according to claim 21 in which the communication network includes a first network part with a limited bandwidth and a second network part with a larger bandwidth, in which the agent is located at the server that interconnects the first network part and the second network part and the client is capable of connection to the first network part.

23. System according to claim 22 in which the first network part is a wireless communication network.

24. System according to claim 21 in which the agent is arranged to have access to a database that can contain usage profiles regarding relevant information indicated by the user of the device and/or information associated with the user and/or data about the device that contains the client.

25. System according to claim 24 in which the database that contains the usage profiles and/or data of the device that contains the client is arranged in such a way that the profiles and/or data in the database can be created, modified and/or added to by means of a further device and/or via a further communication network.

26. System according to claim 21 in which the agent contains a learning module controlled by data supplied by the client.

27. System according to claims 21 in which the client is included in a device of the user that is of the “

always on”

type, or has an automatic answering mode.

28. Computer program intended to run on a server with a server cache comprising at least code parts for sending information over a communication network to at least one client comprising at least the steps of:

maintenance by the program of a server cache containing up-to-date information;

determination by the program of the parts of the up-to-date information that are relevant to the client;

transmission by the program to the client of the relevant information over the communication network at an at least suitable time.

29. Computer program according to claim 28 in which the communication network comprises a large number of clients and the computer program combines usage profiles belonging to various clients.

30. Computer program according to claim 28 in which the computer program, when running on the server, uses the steps of the method according to claim 8.

32. Data carrier according to claim 31 in which at least one part of the data represents a computer program according to claim 30.

31. Data carrier comprising data, the data loadable into the memory of a server in which the data represent a computer program capable of being run on the server, comprising at least code parts for sending information over a communication network to at least one client, comprising at least the steps of:

maintenance by the program of a server cache containing up-to-date information;

determination by the program of which parts of the up-to-date information are relevant to the client;

transmission by the program to the client of the relevant information over the communication network at an at least suitable time.

33. Communication network comprising at least one server and at least one client in which at the server there is agent functionality arranged for executing at least the steps of:

maintenance by the agent of a cache containing up-to-date information;

determination by the agent of which parts of the up-to-date information are relevant to the client;

transmission by the agent to the client of the relevant information over the communication network at an at least suitable time.

34. Communication network according to claim 33 in which the communication network comprises a first network part with a limited bandwidth and a second network part with a larger bandwidth in which the agent is located at the server that interconnects the first network part and the second network part and the client is capable of connection to the first network part.

35. Communication network according to claim 34 in which the first network part comprises a wireless communication network.
