  2. Protocol extension to accelerate the MAG’s knowledge of the MN’s multicast subscription after HO • MAG entity in base solution relays on standard MLD procedures to get knowledge of MN multicast subscription after handover • Several delay sources contribute to increase the timing for multicast delivery at the new point of attachment • Delay due to the access to radio resources among competing MNs • Delay due to radio frame structure • Delay due to retransmissions caused by radio channel unreliability • Delay due to MLD message processing at MN • Solution proposal: to accelerate the MAG’s knowledge acquisition of the MN’s multicast subscription by means of new signaling messages internal to the network, decoupling subscription acquisition from • Underlaying radio technology • IGMP/MLD parametrisation tuning • PMIPv6 multicast architecture (current or evolved)

  3. Predictive handover MN1 pMAG nMAG LMA Mcast source (S1,G1) Mcast Data MN detached MN Detached Event Extended DeReg PBU Multicast info storage in Binding Cache PBA MN attached MN Attached Event PBU LMA decission Extended PBA Multicast group join (S1,G1)
