Performance Evaluation of Networked Virtual Reality Services in a GPRS Network

The General Packet Radio Service (GPRS) network represents an intermediary step between GSM and 3G mobile systems, providing a solution for IP communication between mobile systems and Internet hosts. With packet switching capabilities and a significant increase in data rates comes the potential of accessing advanced Internet services using a mobile terminal. With integrated multimedia components, 3D graphics and real-time interactivity, networked virtual reality (NVR) services may be considered a good representative of these advanced services. This paper examines the capability of currently available GPRS network resources in supporting the Quality of Service (QoS) requirements of NVR services. Measurements of selected QoS parameters have been performed using three different NVR applications, while setting different QoS parameters defined in the Home Location Register (HLR). Results are analyzed to determine the feasibility of deploying NVR services over GPRS networks.
