<p>PURPOSE: A method and a system for enhanced packet transmission in cellular networks are provided to simultaneously optimize the transmission of data flows in a packet switch cellular system. CONSTITUTION: A scheduling mechanism(Sc) of the first cell is coupled with a scheduling mechanism(St) of the second cell. Data having status information concerning an actual data flow is transferred to be handed over from the scheduling mechanism(Sc) of the first cell towards the scheduling mechanism(St) of the second cell(5). At least one of the scheduling mechanism(Sc,St) is ensured by linking at least two schedulers each operating on a different protocol layers. Each PDU(Protocol Data Unit) of an incoming data flow to be transmitted is scheduled by the scheduler(PDU-scheduler) on an upper layer regarding the pre-definable associated quality of service requirements into a priority list to be served by the scheduler(MAC-scheduler) of a lower layer.</p> |
