Making informed decisions…• Requirements for QoE data• Making QoE data available within industry
Based on case studies with• Network operators• Equipment manufacturers• Service providers
Requirements for QoE data
• Provide guidelines on key topics
• Provide tutorials
• Link QoS and QoE variables
• Provide QoE data for different guideline
users
• Provide information about user behaviour
that is feasible to apply
Requirements for QoE data
• Provide guidelines on key topics
• Provide tutorials
• Link QoS and QoE variables
• Provide QoE data for different guideline
users
• Provide information about user behaviour
that is feasible to apply
The main topics of concern• User choice– Reliability of service– Duration of call– Cost-benefit
• User appearance– Head / Upper body– Eye contact– Perception of other
• User groups– Business persons– Deaf persons– Blind persons
• Purpose of communication
– Negotiation– Problem solving– Showing surroundings
• Group communication– Multi-point– Window configuration– Human support
• Technical parameters– Delay– Packet loss– Resolution

Example QoE measure
IF Communication SituationUSING Service PrescriptionWITH Technical Parameters
THEN Usage Outcome
• Prevents adequate communication• Is usable• Offers acceptable quality• Offers good quality• Offers very good quality
Making QoE data available within industry
ETSI Guide
Web-based system
Conclusions• Service developers want end-user data• Much data not available• Tutorial support required• Standardisation bodies well positioned to disseminate
