Abstract
A method for the provision of a defined quality of service in a packet switched communication system with interconnected nodes (N) for the forwarding of data packets is described. The system comprises at least one edge node (EN) for the connection to user equipment (UE) or a further communication system (FS) and for processing data packets. The packets comprise a data field (10) specifying the handling of the packets and the nodes (N) perform a differentiated handling of packets according to said data field (10). The communication system comprises or is connectable to a data base (DB) which contains a record for a user specifying a quality of service. An edge node (EN) which processes a packet for said user is provided with quality parameters from the data base (DB). The edge node (EN) sets the data field (10) specifying the handling of the packet according to the record. Devices and programs to perform the method are also described.
