Experimental performance evaluation of networked virtual reality services in UMTS network

The Universal Mobile Telecommunications System (UMTS) represents an evolution in terms of services and data speeds from "second generation" mobile networks, providing a solution for communication between the mobile devices and Internet hosts. The UMTS has packet switching capabilities and potentially sufficient data rate for accessing the advanced Internet services by using a mobile terminal. Advanced multimedia services, such as networked virtual reality (NVR) services with near real-time interactivity requirements, present a good case study to evaluate the performance of a test UMTS network. In this paper we report the measured performance parameters for NVR services in a UMTS test network and determine the capability of the network to support such services. Results have been shown for two different NVR applications that requires different quality of service (QoS) parameters.
