Abstract

This invention relates to a method and apparatus to control instant message (IM) traffic. A receiver terminal/device provides a filter function to an instant message server. The server checks the filter function to determine whether the receiver is willing to receive a message from a sender terminal/device, and transmits or blocks the message accordingly. The filter function can be modified dynamically, in real time, in response to the needs of the receiver customer. Advantageously, IM traffic can be adapted to emergency conditions.

Claims

1. A method of establishing an instant messaging (IM) session between an IM sender terminal/device (sender) and an IM receiver terminal/device (receiver), comprising the steps of:

providing information for a filter function for said receiver and storing said information in real time;

responsive to a request from said sender to establish a connection to said receiver, testing whether said filter function of said receiver permits instant message sessions from said sender;

if said filter function does not permit an instant message session from said sender to said receiver, blocking said request; and

if said filter function permits an instant message session from said sender to said receiver, establishing such an instant message session between said sender and said receiver.

2. The method of claim 1 wherein a plurality of priority levels can be assigned to instant messages and wherein said filter function can filter differently for different priority levels.

3. The method of claim 2 wherein one of said priority levels is an emergency level and wherein emergency level messages are not blocked.

4. The method of claim 2 wherein one of said priority levels is an emergency level and wherein emergency level messages are blocked only by a rule for a service provider for transmitting said instant messages.

5. The method of claim 1 wherein said filter function comprises a black list of senders whose messages are to be blocked.

6. The method of claim 1 wherein said filter function comprises a white list of senders whose instant message session requests are to be allowed.

7. The method of claim 6 wherein said white list comprises all senders in prescribed network realms.

8. The method of claim 6 wherein said white list comprises all senders in a buddy group.

9. The method of claim 1 wherein said filter function comprises time parameters to limit IM traffic to a receiver during prescribed hours.

10. Apparatus for establishing an instant messaging (IM) session between an IM sender terminal/device (sender) and an IM receiver terminal/device (receiver), comprising:

means for providing information for a filter function for said receiver and storing said information in real time;

means, responsive to a request from said sender to establish a connection to said receiver, for testing whether said filter function of said receiver permits instant message sessions from said sender;

if said filter function does not permit an instant message session from said sender to said receiver, means blocking said request; and

if said filter function permits an instant message session from said sender to said receiver, means for establishing such an instant message session between said sender and said receiver.

11. The apparatus of claim 10 wherein a plurality of priority levels can be assigned to instant messages and wherein said filter function can filter differently for different priority levels.

12. The apparatus of claim 11 wherein one of said priority levels is an emergency level and wherein emergency level messages are not blocked.

13. The apparatus of claim 11 wherein one of said priority levels is an emergency level and wherein emergency level messages are blocked only by a rule for a service provider for transmitting said instant messages.

14. The apparatus of claim 10 wherein said filter function comprises a black list of senders whose messages are to be blocked.

15. The apparatus of claim 10 wherein said filter function comprises a white list of senders whose instant message session requests are to be allowed.

16. The apparatus of claim 15 wherein said white list comprises all senders in prescribed network realms.

17. The apparatus of claim 15 wherein said white list comprises all senders in a buddy group.

18. The apparatus of claim 10 wherein said filter function comprises time parameters to limit IM traffic to a receiver during prescribed hours.
