摘要

Managing multiple services with controlled Quality of Service (QoS) is crucial to 3rd generation cellular system. The real time services, i.e. the traffic classes Streaming and Conversational, will be the most costly services and therefore most crucial to manage in a spectral efficient manner. This paper proposes and evaluates possible ways to accomplish this for the GSM/EDGE Radio Access Network (GERAN). The evaluation is made with different mixes of voice, WWW browsing and video streaming services, where the latter is based on a novel traffic model for a streaming service using an H.263 codec with suitable settings. The results from the dynamic multiple-cell system simulations show that it is possible to efficiently manage streaming services in GERAN, in single as well as mixed service scenarios, by using service based radio resource management algorithms, e.g., power setting.
