Abstract

The application of IP QoS within a wireless system, i.e. UMTS, was carried out in this paper with 3GPP end-to-end QoS scenarios 4 and 5, where RSVP is transported end-to-end. The QoS control in the backbone network was based on Diffserv by utilizing the architecture with edge and border routers, as specified in IETF. Moreover, a mobile-to-mobile call was selected in order to get the most stringent case from a QoS perspective. The QoS concept was evaluated by the conversational multimedia application. The result was that four UMTS bearers were needed, user data bearers for speech and web browsing and time critical and time relaxed bearers for signalling. The bearer characteristic study revealed that optimizations are needed either in the form of signalling reduction or message compression (or both), if we want to achieve the standardized QoS requirements.
