4. Outline IMS QoS Control & 802.21 –IMS trend for real time services –Quick overview of IMS QoS control –Which address of QoS control in 802.21 –IMS and the MIH Communiation model IMS Application Server & 802.21Information Service –Not discussed

5. IMS QoS Control & 802.21 IMS trend for real time services –IMS has been designed in 3GPP as the service/session level provision for real time over wireless IP architectures –802 systems are now also indirectly supporting IMS via the I-WLAN framework –IMS deployment is starting to become a reality as all-IP convergence speeds up –IMS is also the support for fixe-mobile (802-cellular) convergence Anchor for VCC (Voice Call Continuity) HSS External Access to IMS User Access to IMS I-CSCF P-CSCF S-CSCF

6. IMS QoS Control & 802.21 Quick overview of QoS Control in IMS –Application request based (using SIP) –Specific admission control on the Radio Access (via so-called PDF) IMS PDF GGSN UE RNC PDG WAN UE cellular 802 PCSF 11 22 Legend Application resquest 1 Admission Control 2

7. IMS QoS Control & 802.21 Which adress in 802.21 of QoS Control? –Ability to provide the application required QoS is a critical handover criteria –How does the station MIH or MIH PoS in the network is to process the criteria? How are application requests to be adressed to these MIH entities? What assessment/enforcement of available/requiredQoS
