QoS/QoE management in Home
Network
For collaboration among PSOs
Submission Date:
July 1, 2008
Highlight of Current Activities
• PG 204 of TC2, TTA
– TTAS.KO-01.0081
– QoS interworking in heterogeneous network environment
• Different network technologies could be concatenated to cover end-to-end
continuity
• ATM (I.356), IP (Y.1541), FR (X.146)
• Being mapped to specific ATM, IP and Frame Relay QoS classses for UNI-to-UNI
portions
• In Resolution GSC-12/20 : Home Networking
– Recognizing ; that QoS expectations/requirements from users apply to a
wider set of services, and are technologies/networks independent
• Home Network becomes a part of end-to-end QoS/QoE management
– UNI is not the demarcation points any more
– HRACF document has been developed in NGN GSI of ITU-T
2
Strategic Direction
• To support the efficient and consistent end-to-end QoS/QoE
management, QoS/QoE aspects of those technologies being used in
Home Network should be identified and mapped
– Especially mapping with IP Access and Core networks
– Resources control under various Home environments considering various
devices which have different service capabilities

Challenges
• Each technology has developed by his/her own purpose and
philosophy (wired/wireless, fixed/mobile, for voice/multimedia,
long/short distance, etc.)
• Different network technologies have different QoS classes,
performance parameters, performance objectives, example of
applications/services

WiMAX (IEEE 802.16) : UGS, rt-PS, nrt-PS and BE
3G (UMTS) : Conversational, streaming, interactive and background
WiFi (IEEE 802.1d) : 0 ~ 7 class
WiFi (IEEE 802.11e) : 1 ~ 7 class
IP (ITU-T Y.1541) : 0 ~ 7 class
ATM (ITU-T I.356) : 1 ~ 5 class
WiBro : Real time polling, non-real time polling and BE
– Mean Transfer delay, Maximum Delay, 1-10-3 quantile, 10-8 quantile,..

Next Steps/Actions
•
•
•
PSOs having a responsibility to develop a specific standard for those protocols
and QoS/QoE aspects, should take into account the mapping system among
different technologies for Home Network
For the development of new technologies, it should be considered the
collaboration among PSOs, e.g. RACF in Home Network
On the next revision of TTAS.KO-01.0081 document in TTA, the mapping table
and rationale of Home Network-related protocols will be added

Proposed Resolution
• No need to change current Resolution in Res. GSC-12/20
