FLOW BASED PACKET MANIPULATION CONGESTION CONTROL
First Claim
Patent Images
1. A method in a first network node of a communication network, for marking of Protocol Data Units, PDUs on a first protocol layer, the method comprising:
- receiving PDUs of a flow on a second protocol layer;
extracting information about said flow and storing said information being extracted;
marking PDUs on the first protocol layer, where said first protocol layer PDUs being marked correspond to second protocol layer PDUs that are appropriate for manipulation based on said stored information; and
sending PDUs on the first protocol layer that is a lower protocol layer than said second protocol layer.

Abstract
This disclosure relates to a Radio Network Controller, RNC, a base station, and to methods therein. By extracting information from one or more flows of Protocol Data Units, PDUs, which information is accessible on a certain protocol layer only, congestion control is enabled and performed on another protocol layer based on said information.
The present disclosure avoids that inappropriate PDUs are discarded, which else would inappropriately affect the user performance.

10. A first network node for marking of PDUs on a first protocol layer, the network node comprising:
-
a first interface configured to receive PDUs of a flow on a second protocol layer; a processor configured to extract information about said flow and to store information being extracted in a database; a marking unit configured to mark first protocol layer PDUs that correspond to second protocol layer PDUs that are appropriate for manipulation based on information stored in the database; and a second interface configured to send PDUs on the first protocol layer that is lower protocol layer than said second protocol layer. - View Dependent Claims (11, 12, 13, 14)

15. A method for manipulating PDUs on a first protocol layer in a second network node of a communication network, the method comprising:
-
receiving from a first network node PDUs on a first protocol layer, wherein said first protocol layer PDUs comprise marked first protocol layer PDUs that correspond to second protocol layer PDUs that are appropriate for manipulation; detecting a condition at least indicative of congestion in the communication network, selecting one or more marked PDUs on the first protocol layer, based on the detected condition; and manipulating said selected PDUs. - View Dependent Claims (16, 22, 23, 24)

25. A second network node for manipulating PDUs, the second network node comprising:
-
an interface configured to receive PDUs on a first protocol layer, wherein the first protocol layer PDUs comprise marked first protocol layer PDUs that correspond to second protocol layer PDUs that are appropriate for manipulation; a processor configured to detect a condition at least indicative of congestion, to select one or more marked first protocol layer PDUs in response to the detected condition at least indicative of congestion; and
to manipulate said selected one or more marked first protocol layer PDUs. - View Dependent Claims (26, 27, 28)
