Workshop on Selected Items on Telecommunication Quality Matters

Overview

This workshop on "Selected Items on Telecommunication Quality Matters" aims at connecting experts working in this area and providing them the opportunity to present their work and share their experiences.

Objectives of the Workshop

The main objectives of the workshop are to:

• Discuss hot issues from a terminal quality perspective
• Discuss different perspectives of Quality of Experience including voice services.
• Discuss several issues related to transmission planning
• Present information about future conferencing systems, end-to-end architecture for improvements in QoS 
• Exchange information and establish relationships between research, state and industrial organizations involved in the topic
• Discuss the concepts of 'net neutrality' & ‘differentiated traffic management' and their potential impact on QoS as perceived by the user

Topics covered in the workshop include: 

• Features in Terminals
• Quality of Voice Services
• Measurements of terminals and terminal architecture
• End to end architecture for improvements in QoS
• HD and CAT-iq voice experiences
• Voice Quality by Codec design
• Future Conferencing Systems
• Quality of Experience (Where we are, Standardization and architectures for QoE)
• Transmission Planning for IP-based multi services and Future of the E-Model
• Regulatory Approaches to QoS in today's heterogenous packet network
