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

(Mobile)WiMAX

IP

WiFi Ethernet

3G

DCT

Bluetooth

IP Core

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
