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.
Claims21
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;
- and
- breaking the end user traffic in and out of a tunnel between the end user and an access gateway, in order to perform said adapting, wherein the access gateway is a gateway for nodes outside the mobile network to access the mobile network.
A radio network node of a mobile telecommunication network, the radio network node comprising:
- a proxy circuit for determining a TCP session based on TCP parameters adapted for a radio link on which end user traffic is to be transported;
- a radio resource management circuit to send feedback to the proxy circuit, 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;
- break in/out circuit configured to break the end user traffic in and out of a tunnel between the end user and an access gateway, in order to perform said adapting;
- wherein the TCP session is originated from the radio network node, which TCP session is used to transport the end user traffic, and wherein the access gateway is a gateway for nodes outside the mobile network to access the mobile network.
A computer program product stored in a non-transitory computer readable medium for controlling a proxy in a radio network node to enable traffic acceleration in a mobile telecommunication network, the computer program product comprising software instructions which, when run:
- causes the proxy in 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, wherein the TCP parameters 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 which is used to transport the end user traffic;
- and
- causes a break in/out circuit in the radio network node to break the end user traffic in and out of a tunnel between the end user and an access gateway, in order to perform said adapting, wherein the access gateway is a gateway for nodes outside the mobile network to access the mobile network.
