  1. Problem Statement and Requirement: Mobile Multicast H. Deng, P.Yang, Q. Wu denghui@chinamobile.com

  2. Profile of Mobile IPTV Reference: ITU-T Focus Group on IPTV

  3. QoE/QoS for Mobile IPTV • Total Multicast bandwidth: Access Node ability • Current available bandwidth: Access Node aware • Connection Admission Control: available resource • Network Attachment Control: privilege user • Packet loss/Priority: Time of Handover • Synchronization: Stream synchronization • Notification: Reference: ITU-T Focus Group on IPTV

  4. Mobile IPTV security requirement • IPTV architecture shall be robust against denial of service attacks targeting any multicast mechanisms. • Multicast system architecture shall provide a mechanism of multicast protocol adjacency authentication in order to establish a reliable peer. • Multicast system architecture shall provide an admission control mechanism to regulate any multicast events. • Multicast system architecture shall be independent of adjacent domain such that it shall not affect the adjacent multicast domain without permission. • Multicast system architecture shall provide a mechanism to check integrity of multicast contents before service delivery such that it prevents unauthorized contents from becoming the content source. Reference: ITU-T Focus Group on IPTV

  5. Use of MIP6 for multicast based Mobile IPTV • Bandwidth efficiency: bidirectional tunneling overhead and latency • Packet loss/Priority: Mobile IPv6 handover • Synchronization: all the nodes in Mobile IPv6 and Mobile IPTV have to be synchronized, PMIP does require synchronization between MAG and LMA. • Notification: both happen in MIP6 and Mobile IPTV.

  6. Issue about mobile multicast • In the case of mobile node frequently joins and quits from the multicast group,[MBMS] may experience overload for each network entity such as access gateway and broadcast/multicast server.

  7. Conclusion • Multicast mobility for mobility network and Mobile IPTV services have been discussed. • Impacts on Mobile IPv6 were also discussed.
