Submission DateJuly 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

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

IP Core
DCT
(Mobile) WiMAX
3G
IP
WiFi
Ethernet
Bluetooth

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,..

5
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.
