  Enhancing QoS and QoE in IMS enabled Next Generation Networks
Titel: Enhancing QoS and QoE in IMS enabled Next Generation Networks
Auteur: Kamaljit I. Lakhtaria
Verschenen in: The international journal on applications of graph theory in wireless ad hoc networks and sensor networks : J GRAPH-HOC

Jaar: 2010
Inhoud: Managing network complexity, accommodating greater numbers of subscribers, improving coverage tosupport data services (e.g. email, video, and music downloads), keeping up to speed with fast-changingtechnology, and driving maximum value from existing networks – all while reducing CapEX and OpEXand ensuring Quality of Service (QoS) for the network and Quality of Experience (QoE) for the user.These are just some of the pressing business issues faced by mobileservice providers, summarized bythe demand to “achieve more, for less.” The ultimate goal of optimization techniques at the networkand application layer is to ensure End-user perceived QoS. The next generation networks (NGN), acomposite environment of proven telecommunications and Internet-oriented mechanisms have becomegenerally recognized as the telecommunications environment of the future. However, the nature of theNGN environment presents several complex issues regarding quality assurance that have not existed inthe legacy environments (e.g., multi-network, multi-vendor, and multi-operator IP-basedtelecommunications environment, distributed intelligence, third-party provisioning, fixed-wireless andmobile access, etc.). In this Research Paper, a service aware policy-based approach to NGN qualityassurance is presented, taking into account both perceptual quality of experience and technologydependantquality of service issues. The respective procedures, entities, mechanisms, and profiles arediscussed. The purpose of the presented approach is in research, development, and discussion ofpursuing the end-to-end controllability of the quality of the multimedia NGN-based communications inan environment that is best effort in its nature and promotes end user’s access agnosticism, serviceagility, and global mobility.
