1. A packet transmission method for transmitting data packets via a telecommunication network, comprising the steps of:
a) judging a quality of a received data packet;
b) tagging said data packet by adding dropping information in response to the result of said judging step; and
c) dropping said tagged data packet based on said added dropping information, when a predetermined dropping condition is met, wherein said quality is judged on the basis of an uplink quality parameter and/or a downlink power control status, wherein said data packet is an ATM cell and defective data frames are packed into the same ATM cell, and wherein those ATM cells which contain only defective frames are tagged in said tagging step.
