Managing network complexity, accommodating greater numbers of subscribers, improving coverage to




support data services (e.g. email, video, and music downloads), keeping up to speed with fast-changing




technology, and driving maximum value from existing networks – all while reducing CapEX and OpEX




and 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 by




the demand to “achieve more, for less.” The ultimate goal of optimization techniques at the network




and application layer is to ensure End-user perceived QoS. The next generation networks (NGN), a




composite environment of proven telecommunications and Internet-oriented mechanisms have become




generally recognized as the telecommunications environment of the future. However, the nature of the




NGN environment presents several complex issues regarding quality assurance that have not existed in




the legacy environments (e.g., multi-network, multi-vendor, and multi-operator IP-based




telecommunications environment, distributed intelligence, third-party provisioning, fixed-wireless and




mobile access, etc.). In this Research Paper, a service aware policy-based approach to NGN quality




assurance is presented, taking into account both perceptual quality of experience and technology-




dependant quality of service issues. The respective procedures, entities, mechanisms, and profiles are




discussed. The purpose of the presented approach is in research, development, and discussion of




pursuing the end-to-end controllability of the quality of the multimedia NGN-based communications in




an environment that is best effort in its nature and promotes end user’s access agnosticism, service




agility, and global mobility.
