Abstract

The present invention relates to a method for traffic flow treatment in a core network of a communication network. The method may comprise receiving cell information from an access network of the communication network, wherein the received cell information comprises an indication of a congested cell of the communication network. Furthermore, the method may comprise receiving subscriber specific information comprising real-time information of a subscriber in a cell of the communication network. The method may further comprise analyzing the received subscriber specific information and controlling the traffic flow in the core network according to the analysis of the subscriber specific information.

First claim

The invention claimed is:

1. A method for traffic flow treatment in a core network of a communication network, the method comprising:
receiving cell information from an access network of the communication network, wherein the received cell information comprises an indication of a congested cell of the communication network;
receiving subscriber specific information comprising real-time information of a subscriber in a cell of the communication network;
analyzing the received subscriber specific information to identify at least one application run by the subscriber; and
controlling the traffic flow in the core network for each of the at least one application in accordance with the received cell information including the indication of the congested cell.

2. The method according to claim 1 , further comprising:
receiving cell information as a real-time information.

3. The method according to claim 1 , further comprising:
identifying a congested cell utilizing information from a RAN.

4. The method according to claim 1 , further comprising:
receiving information to identify subscriber specific information of a subscriber located in the congested cell.

5. The method according to claim 1 , further comprising:
sending a trigger signal for updating a policy of the subscriber in the core network.

6. The method according to claim 1 , further comprising:
reporting detected service traffic within the core network.

7. The method according to claim 1 , further comprising:
controlling data flow of a certain kind.

8. The method according to claim 1 , further comprising:
updating subscriber specific policy in the core network.

9. The method according to claim 1 , further comprising:
controlling the traffic flow in the core network according to policies of the core network.

10. The method according to claim 1 , further comprising:
utilizing packet data protocol (PDP) context in the core network.

11. The method according to claim 1 , further comprising:
receiving application information.

12. The method according to claim 1 , further comprising:
utilizing information from an internet protocol connectivity access network (IPCAN) session in the core network.

13. A network element installed in a core network, the network element comprising:
at least one memory comprising computer program code;
at least one processor;
wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the network element at least to:
receive cell information and for receiving subscriber specific information comprising real-time information of a subscriber in a congested cell of the communication network;
analyze the cell load information and the received subscriber specific information to identify at least one application run by the subscriber; and
send controlling information in order to control the traffic flow in the core network for each of the at least one application in accordance with the received cell information including the indication of the congested cell.

14. A computer program embodied on a non-transitory computer-readable medium, comprising code portions for causing a network element on which the computer program is executed, to carry out a method comprising:
receiving cell information from an access network of the communication network, wherein the received cell information comprises an indication of a congested cell of the communication network;
receiving subscriber specific information comprising real-time information of a subscriber in a cell of the communication network;
analyzing the received subscriber specific information to identify at least one application run by the subscriber; and
controlling the traffic flow in the core network for each of the at least one application in accordance with the received cell information including the indication of the congested cell.
