Method of linking two schedulers of a multi-layer network and a network comprising a transceiver having linking functionality for two schedulers

摘要

The invention addresses the problem of multi-layer scheduling in a packet switched network or system, especially in a mobile telecommunication system. It is an object of the invention to provide a new and improved scheduling approach to allow for very efficient scheduling.According to the invention it is proposed a packet switched network and a method for providing quality of service in a packet switched network based on at least two hierarchically structured protocol layers with respective schedulers by the steps of providing upper layer protocol data units (PDUs) of an incoming data flow within a priority order of a definable data-flow-queue to be served by the scheduler (MAC-scheduler) of a lower layer for data transmission, selecting a protocol data unit (PDU) on demand of the scheduler (MAC-scheduler) of the lower layer in dependence of the priority order and actual network constraints, and serving the selected protocol data unit by the scheduler (MAC-scheduler) of the lower layer.
