Key Messages to Take Away (1) • 802. 21 Already provides support for handovers between bidirectional link technologies (e. g. 802. 16, 802. 11, Cellular) • New SG created in 802. 21 to address the case when handover is made from/to unidirectional (e. g. downlink only) technologies 2

Possible Approach for 802. 21 Higher Layer Transport MIH Users Higher Layer Transport MIH Function DL-only Interface (e. g. DVB) 3 GPP/ 3 GPP 2 Interface MGMT MIH Users DATA 802 Interface Mobile Node DATA MGMT Higher Layer Transport MIH Users MIH Function 3 GPP/3 GPP 2 Network 802 Interface Higher Layer Transport MIH Users MIH Function DL-only Network (e. g. DVB) 802 Network Legend MIH Message Transport MIH Local Interface 3

Key Messages to Take Away (2) • Converged devices including both types of technologies already exist • This is a market opportunity for 802. 16 – Wi. MAX !! • E. g. SK Telecom in Korea has both Wi. Bro and DMB networks 4

Next Steps • Finish PAR/5 C and get it approved by • Form a new TG in 802. 21 to amend the baseline specification to support handovers with downlink-only technologies 5
