This paper is devoted to the problem of evaluating the quality of experience (QoE) for a given multimedia service based on the values of service parameters such as QoS indicators. This paper proposes to compare two self learning approaches for predicting the QoE index, namely the approach based on logic circuit learning and the approach based on fuzzy logic expert systems. Experimental results for comparing these two approaches with respect to the prediction ability and the performance are provided.

Discovering and redirecting multimedia services in a personalized manner is achieving increasing importance for mobile users. It is a powerful characteristic, one of the endless capabilities of mobile ecommerce technology. Regardless of their location, users are able to find and utilize services according to their needs and without complex configuration and preknowledge of service interfaces. In addition, they gain control over how, where, and when multimedia services are delivered. Mobile agent platforms may contribute significantly as a supporting component of the overall personalized multimedia service infrastructure. In order to appreciate the impact of MA-based solutions in personalized multimedia service platforms, we present a set of basic criteria related to mobile agents, which may evaluate their necessity and usage. Although it is not an exhaustive list of evaluation criteria, it is sufficient to cover a broad variety of areas under consideration regarding the involvement of mobile agents in service platforms.

Concise Description

Although promised for some time now, advanced multimedia services for mobile devices were not yet a reality. With IMS (IP Multimedia Subsystem), the fundaments for advanced multimedia services based on IP will be laid. However, there are still a lot of confusions about IMS that may hinder its success. In this chapter, a comprehensible presentation of IMS together with its potential regarding the development of advanced services is given. The chapter starts with a justification of the existence of IMS. The necessary adaptations of SIP (Session Initiation Protocol) are explained. A concise description of IMS will be provided. Next, the deployment of IMS in fixed – mobile environments will be examined thoroughly. The heart of the chapter is the presentation of the strengths of IMS, that is, what can IMS be used for. A few advanced multimedia service scenarios are given as illustration. The chapter will also consider the most important but yet neglected component of the whole IMS, namely the IMS client. The chapter concludes with a summary of the challenges that must be resolved.

The concept of PQoS, although in general it deals with the user satisfaction with a specific delivered/ requested service, is in practice significantly differentiated by the nature of each delivered service. This chapter reviews various existing PQoS assessment methods for video, VoIP, online games, and Web services that have been published in the literature. It then moves beyond the current PQoS assessment methods and presents novel techniques for predicting the PQoS of a multimedia service.
