Abstract

A radio network node of a mobile telecommunication network. The radio network node configured to determine a TCP session based on TCP parameters adapted for a radio link on which end user traffic is to be transported. The radio network node also configured to originate the TCP session which is used to transport the end user traffic.

Claims

1. A method for enabling traffic acceleration in a mobile telecommunication network, the method comprising:

determining by a proxy in a radio network node in the telecommunication network, a TCP session based on TCP parameter settings adapted for a radio link on which end user traffic is to be transported, which TCP parameter settings for traffic sent on the radio link to the end user are based on feedback to the proxy from a radio resource management function in the radio network node;

originating the TCP session from the radio network node, which TCP session is used to transport the end user traffic.

2. The method for enabling traffic acceleration according to claim 1, wherein the traffic is received by the radio network node from a server outside the mobile network via an edge server in the radio network node.

3. The method for enabling traffic acceleration according to claim 2, wherein further TCP parameter settings for end user traffic sent through an upstream acceleration tunnel to a server outside the mobile network are based on feedback to the proxy from the edge server in the radio network node.

4. The method for enabling traffic acceleration according to claim 2, wherein the proxy is incorporated in the edge server.

5. The method for enabling traffic acceleration according to claim 2, wherein an IP address of the edge server in the radio network node has been received by the end user from a content provider located external the mobile network.

6. The method for enabling traffic acceleration according to claim 1, wherein the radio network node is a radio network controller in a 3G network.

7. The method for enabling traffic acceleration according to claim 1, wherein the radio network node is an evolved Node B in an LTE network.

8. The method of claim 1, wherein the radio network node is an access node between the end user and a core network.

9. A radio network node of a mobile telecommunication network, the radio network node comprising a processor and a memory, the memory containing instructions executable by the processor whereby the radio network node is configured to:

determine, by a proxy in the radio network node, a TCP session based on TCP parameter settings adapted for a radio link on which end user traffic is to be transported, which TCP parameter settings for traffic sent on the radio link to the end user are based on feedback to the proxy from a radio resource management function in the radio network node; and

originate the TCP session from the radio network node, which TCP session is used to transport the end user traffic.

10. The radio network node of claim 9, wherein the memory contains instructions executable by the processor whereby the radio network node is configured to send feedback to the proxy, which feedback is based on state of the radio link towards the end user, from a radio resource management function in the radio network node.

11. The radio network node according to claim 9, further comprising a user edge server configured to send feedback to the proxy, which feedback is based on state of a link towards a server outside the mobile network.

12. The radio network node according to claim 9, wherein the radio network node is a radio network controller in a 3G network.

13. The radio network node according to claim 9, wherein the radio network node is an evolved Node B in an LTE network.

14. The radio network node according to claim 9, wherein the radio network node is an access node between the end user and a core network.

15. A computer program product stored in a non-transitory computer readable medium for controlling a radio network node to enable traffic acceleration in a mobile telecommunication network, the computer program product comprising software instructions which, when run, cause the radio network node to:

determine a TCP session based on TCP parameters adapted for a radio link on which end user traffic is to be transported; and

originate the TCP session which is used to transport the end user traffic.

16. The computer program product of claim 15, wherein the TCP parameters comprise settings for traffic sent on the radio link to the end user based on feedback to the proxy in the radio network node from a radio resource management function in the radio network node.
