Challenges for Quality of Experience Engineering for Added Value Services
1.1. Introduction and challenges
In recent years, multimedia applications and services have experienced a sudden growth. Today, the video display is not limited to the traditional areas of movies and television on TV sets, but accesses these applications in different environments, devices and under different conditions.
In addition, the continuous emergence of new services along with increasing competition is forcing network operators and service providers to focus all their effort onto customer satisfaction, although determining the Quality of Experience (QoE) is not a trivial task.
Due to the emergence of different kinds of communication and networking technologies (core networks with intra-domain and inter-domain challenges, access networks, aggregation networks, spontaneous networks, Internet of Things, etc.) and the current and envisaged proliferation of different and specific types of services supported by these technologies (real-time services, IPTV, VoD, social networking, E-Health, multimedia, gaming, smart cities, etc.), traditional network control strategies are not sufficient to handle the complexity and diversity of information in use that we see today. There is a strong need to develop a new paradigm to obtain the continuity of network services based on the new concept of smart communications and user interaction. The user’s perception, such as ...
