5. A digital mobile communication network component comprising:

reception means for receiving information being indicative of network traffic;

detection means for detecting a traffic condition of a digital mobile communication network during an ongoing communication session based on the information received by the reception means;

selection means for selection of an interleaving length during the ongoing communication session based on the traffic condition detected by the detection means;

means for indicating the selection of the interleaving length to an end-user communication device.

6. The digital mobile communication network component of claim 5 , wherein the selection means selects a first interleaving length if the traffic condition is that the digital mobile communication network is not congested and a second interleaving length when the network is if the traffic condition is that the digital mobile communication network is congested, the second interleaving length being substantially longer than the first interleaving length.
