The present invention relates to a method and system for controlling header compression in a packet data network, e.g. an IP based cellular network. A load information of the packet data network is obtained, and header compression is triggered in response to the result of an evaluation of the load information. In particular, the header compression can be applied only for one direction, provided that the load information indicates asymmetry. Thereby, the headers can be compressed only on demand and only in the direction where the traffic volume is higher and where, in effect, the transmission capacity is the bottleneck. As a result, header compression takes less processing power and thus allows more flows to be compressed. |
