Abstract

The invention relates to a method for routing streams of traffic in IP networks, particularly in mobile IP networks. The invention involves a plurality of streams of traffic to be transmitted being routed such that they are transmitted in a carrier/context (7). The plurality of streams of traffic at different destination networks (5; 6) and/or demands on transmission quality for the respective stream of traffic are merged and are transmitted from a terminal (3) via one carrier/context (7) to a network access node (4) in the IP network and are routed from there to the respective destination networks and devices.

Claims

1. A method for routing streams of traffic in IP networks or in mobile IP networks, characterized in that a plurality of streams of traffic to be transmitted are routed in such a way that they are transmitted in one carrier or context (7), wherein several streams of traffic for different destination networks (5;

6) and/or demands on transmission quality for the respective stream of traffic Quality of Service;

QoS are merged and are transmitted from a terminal (3) via one carrier/context (7) to a network access node (4) of the IP network.via a carrier or context (7), wherein the transmission of the streams of traffic takes place regardless of whether they must be distinguished with regard to destination network and/or QoS.

2. The method according to claim 1, characterized in that the transmission of the streams of traffic from the terminal (3) to the network access nodes (4) takes place via an air interface.

3. The method according to claim 2, characterized in that rules and filter criteria for statically or dynamically controlling a local network access node (4) of the IP network are configured by its own network or by another network.

4. The method according to claim 3, characterized in that the rules and filter criteria for controlling a local network access node (4) are stored in the access network node.

5. The method according to claim 4, characterized in that the number of the streams of traffic routed together is not limited.

6. A computer program for the carrying out of the method according to claim 1.

7. The method according to claim 1, characterized in that rules and filter criteria for statically or dynamically controlling a local network access node (4) of the IP network are configured by its own network or by another network.

8. The method according to claim 3, characterized in that the rules and filter criteria for controlling a local network access node (4) are stored in the access network node.

9. The method according to claim 1, characterized in that the number of the streams of traffic routed together is not limited.

10. The method according to claim 2, characterized in that the number of the streams of traffic routed together is not limited.

11. The method according to claim 3, characterized in that the number of the streams of traffic routed together is not limited.

12. A computer program for the carrying out of the method according to claim 2.

13. A computer program for the carrying out of the method according to claim 3.

14. A computer program for the carrying out of the method according to claim 4.

15. A computer program for the carrying out of the method according to claim 5.
