“…However, the authors could not provide QoS measurements for both voice and data services at the same time. In [14], a methodology for evaluating the quality of file transfer protocol data service in cellular universal mobile telecommunications system (UMTS) networks based on data collected through drive testing is presented. Although user experience was taken as a key factor in determining the network operator's success, it was only evaluated based on data services on a single network.…”

The widespread demand for data applications over mobile networks requires that service providers guarantee a well-defined quality of service (QoS) KEYWORDS Quality of service, multi-criteria decision making, analytic hierarchy process, web browsing & mobile networks 1.INTRODUCTIONOne of the objectives of wireless mobile networks is the provision of required quality of service (QoS). Whether the QoS level is measured from the end-users' experience or obtained from the network's switching centre, its aim is to improve subscribers' loyalty to a particular brand of service provider as well as yield more revenue to the operator. According to [1] and [2], enhancements in the form of higher data rates, QoS, security measures, location-awareness, new flexible communication capabilities, etc. are needed to enable wireless networks support demands for voice, data, and multimedia services. With the continuous growth in data rates, operators are forced to more-intelligently manage the traffic on their networks. Since different applications have different QoS requirements, efficient mechanisms (admission control, resource reservation, and packet scheduling) are needed to provide guaranteed QoS. In [3], the network-centric and end-system based approaches are proposed to support QoS guarantees. The former requires network devices such as routers, switches, and base stations to provide QoS support to satisfy data rate, bounded delay, and packet loss requirements by applications [4][5] while the latter does not impose any requirements on the network. Instead, control techniques are employed by the end systems to maximize the quality demanded by applications.

“…The types of tasks that are included in the test depend on what particular data service needs to be tested. In practice, one would at least test ping, FTP upload, FTP download and HTTP based web browsing [7,8]. The PS data server needs to be configured properly so that it is able to act as a termination point for all data calls.…”

This paper presents a user-centric and application-specific QoS assessment methodology for cellular communication networks. Specifically, it uses the Analytic Hierarchy Process (AHP) to evaluate QoS as a multi-criteria decision problem that represents how well cellular networks' data services are perceived given particular sets of application classes and relative to other networks servicing in the same area. As part of the methodology, drive testing is performed to collect objective measurements associated with identified QoS criteria for data services. Once drive testing is performed and data collected, multiple networks are compared to determine the network that provides higher QoS based on users' perception of quality. The selection of the best performing network is based on the output provided by the AHP approach, which is used as unified measurement of the perceived QoS by users on different networks.In order to determine application-specific priorities, the approach presented uses three different application classes, including Emergency, Business, and Personal. For each class, the relative importance of each quality evaluation criteria is adjusted in the AHP procedure to reflect the priorities of the services expected. Through several case studies, the approach is proven successful in providing a way for analyzing user-centric QoS for application-specific scenarios.
