Case Study in Assessing Subjective QoS of a Mobile Multimedia Web Service in a Real Multi-access Network

Abstract

Abstract. This paper presents an empirical task-based user evaluation, which was carried out for the purpose of assessing the subjective QoS of a mobile multimedia web service in a real multi-access network environment comprising of WLAN and GPRS networks and automatic mobility management with Mobile IP. Subjective quality ratings were collected from 20 test users to obtain a distribution representing the service quality experienced by the subjects. The obtained results show that even though the service usability in GPRS domain was barely satisfactory, this type of automatic utilization of multiple access networks with some enhancements can be considered as a potential access method for mobile services.

Seamless Connectivity in WLAN and Cellular Networks with Multi Criteria Decision Making

“…CRITERIA The subjective quality combines the human perception and the objective quality [12]. The objective quality consists of four components, transport quality being one of them.…”

M 4 : multimedia mobility manager

“…However, Sutinen et al [25] performed a case study in assessing subjective QoS of a mobile multimedia web service. Promising results from an empirical task-based user evaluation of the enduser QoS were presented.…”

Reflecting QoS of low-cost multi-provider municipal WiFi on commercial 3.G mobile data and ISM spectrum occupancy

“…In the context of the panOULU network, we have previously published an analysis of the usage of the network at its early stages [14], an empirical assessment of the subjective QoS of a multimedia web service in a multi-access network [19], a study on the need and support for session mobility in the network [15], and a report of the triple helix of the university-industry-government relations underlying the establishment, evolution and status quo of the network [19]. As discussed in the related work, there are few recent studies reporting empirical QoS comparisons between WiFi and mobile data networks.…”
