 Primary MBS Distribution DPF is unique per MBS zone
 Act as IGMP client to send IGMP report message to the
last MR between ASN and CSN to join IP multicast
group tree between ASN and CSN

WiMAX PS
 Phase 2 Requirements
 MN initiated activation of additional MCBCS sessions
while delivering the MCBCS program.
 Dynamic multicast group support enabling applications
like multi-player games.

IGMP/MLD PS
 One issue is message authentication
 Another issue is IGMP/MLD unsolicited group reports
 Yet another issue is the user authentication

PMIPv6 PS Draft
 http://ietfreport.isoc.org/all-ids/draft-deng-multimob-pmip6requirement-01.txt
 This draft needs to be rewritten
 Feedback obtained from IETF 73 BoF
 Emphasis on traffic requirements
 Do we need PMIPv6 protocol changes to support multicast?
 Do we need any normative behavior at MAG?
 Do we need any normative behavior at LMA?
IETF 74: Multimob Informal Meeting
14
PMIPv6 PS Draft
 In PMIPv6, for MN MAG is the default router but MN
does not know LMA
 Do we need any handover support?
 Based on all of the above come up with a new draft
 Please volunteer to contribute text
 We need to get feedback from netlmm chairs
 We need to get feedback from netlmm people

Solution Drafts
 We have 3-4 PMIPv6 solution drafts
 We have one MLD/IGMP extension draft
 We have several MIPv6/HMIPv6 solution drafts
 We have one MIPv4 solution draft
 We have one FMIPv6 solution draft
 We have one Nemo solution draft
 We have other solution drafts
