Abstract

The present invention relates to a telecommunication method in a wireless cellular telecommunication system having a radio network controller and a base station, where the method receives a number of orthogonal variable spreading factor codes from the radio network controller by the base station, evaluates a load situation by the base station, and in case the orthogonal variable spreading factor codes received from the radio network controller are insufficient for the load situation: requesting a change of the number of orthogonal variable spreading factor codes from the radio network controller by the base station.
