Abstract :
This paper describes a novel signaling procedure designed to enhance standard transport layer protocols (RTP/RTCP) for the effective management of end to end QoS control over mobile radio networks. The basic signaling procedure has been originally defined in order to allow the QoS manager entity (at the Internet service provider side) to react fast to sudden radio link outage due to cell reselections. It utilises data link-transport layer inter-protocol signaling and a fast signaling mode. The procedure has been developed in details for its introduction within the GPRS/EDGE system; its effectiveness has been verified in a number of real scenarios where standard schemes have proved to be inadequate.
