Research Areas
We address three areas and work on IPTV over WiMAX for these three areas. Note that we don't imply that we will have a deliberative item per area. This is just our formation. We may deliver three items from one of area depending on discussions with Huawei.
Network: Mobility and Multicast Layered Multicast for IP multicast/MCBCS Quality adaptation for IPTV on WiMAX

Research Topics
The multicast states transfer when MN is roaming. We consider the PMIP case and assumes MAG is available in the ASN. There are two possibilities here, 1) State trasfer from LMA to MAG during the binding registration, 2) State transfer from old MAG to new MAG. The 2) approach has several problems such as new MAG discovery and security association between MAGs,etc. The assumed states are …

Research Topics
About MCBCS Support We believe whether MCBCS is used in wireless path is nothing t
o do with the IP network design and IP multicast design unless we consider layered-multicast (see the research area2).
L3 is nothing to do with the L2 transport method. From L3 point of view, either P2P-unicast or MCBCS is same.
If Huawei is interested in, we can investigate the Multicast ID mapping to IP flow. Only our concern is that many people has already worked on this topic (ex. 16ng).

2. Layered Multicast Area
![Page 20: Network Design. Our assumption Primary target: Mobile Router Scenarios NEMO Basic Support only NEMO Basic Support and PMIPv6 support on WiMAX MR uses.](https://reader034.fdocuments.in/reader034/viewer/2022042822/56649e2c5503460f94b1ae7e/html5/thumbnails/20.jpg)
Layered multicast foradaptive modulation
Problem statement With WiMAX multicast, multicast data transmission rate depends
on the link capacity of the node whose link quality is worst Nodes with good wireless connection cannot get high-quality multi
cast data Combination of layered multicast and adaptive modulation
Nodes come to be able to receive the multicast data with proper quality depends on their wireless connection quality
Key Technolgies Layered multicast
Network resource aware multicast data transmission method Multicast group management
Dynamic IP multicast group management based on the nodes’ current physical layer modulation
Mapping between an IP multicast group to a modulation based WiMAX multicast group

Layered Multicast
Hierarchical data structure Data are divided into several “Layer”
Layer is multimedia data unit Video quality control selecting the num
ber of accepting layers Layer
Base Layer Base Multimedia data
Enhanced Layer Quality enhancement data
Multicast tree structure Data are deliverd with IP multicast Senders provide maximum quality data Intermediate nodes decrease layers to se
nd adapting to the network resource

3. Quality adaptation for IPTV on WiMAX
![Page 25: Network Design. Our assumption Primary target: Mobile Router Scenarios NEMO Basic Support only NEMO Basic Support and PMIPv6 support on WiMAX MR uses.](https://reader034.fdocuments.in/reader034/viewer/2022042822/56649e2c5503460f94b1ae7e/html5/thumbnails/25.jpg)
Our assumption and primary target
Network Scenario: NEMO Basic Support only NEMO Basic Support and PMIPv6 support on wimax
Target: focusing on “multicast over unicast” Providing the stable IPTV broadcast quality
help reducing quality losses Reduce the time in which the quality is kept bad
Adaptation range for keeping quality Between BS and Mobile router The upper range could be based on QoS (L3, L2)
