  1. Mobility Management for Multicast Sessions In a UMTS-IP Converged Environment Leoleis, G.; Dimopoulou, L.; Nikas, V.; Venieris, I.S. ISCC 2004. Advisor: Yuh-Shyan Chen Student: Kau-Lin Chiu Date: March 8, 2006

  2. Outline • Introduction • MBMS Service Description • UMTS Extensions for MBMS • MBMS Support in Converged UMTS-IP Environment • Conclusions

  3. Introduction • Multicasting appears as a straightforward solution to facilitate one- or many-to-many delivery of packet switched service. • In B3G network, the UMTS core network are replaced by pure IP mobility and multicast functionality

  4. Multimedia Broadcast/Multicast Service • MBMS is defined as a network layer UMTS service that adopts a unidirectional (downstream) point-to-multipoint data delivery mechanism. • The Broadcast-Multicast Service Center (BM-SC) • Control information flows exchanged with 3PP of MBMS data • Manage AAA information associated with third parties

  5. MBMS Service Description-Network Architecture

  6. MBMS Service • Subscription • Service Announcement • Joining - Bearer Activation • Session Start • Notification • Data Transfer • Session Stop • Leaving - Bearer Deactivation

  7. MBMS Contexts Standby No resource allocation Active Resource reservation and transfer

  9. Relocation Procedure

  10. UMTS Extensions for MBMS--Connected Mode Register De-Register

  11. MBMS Support in Converged UMTS-IP Environment • The UMTS CN towards a fully IP-based mobile-aware network, a hybrid mobility management model based on both UMTS and Mobile IPv6 (MIPv6) mechanisms is proposed.

  12. Target Network Architecture • RASH: executing MIP function and traditional PS service • Hide radio access technologies • Terminate the access stratum and the non-access stratum

  13. RASN Relocation

  14. Conclusions • this paper has described the principles of the multicast mode MBMS architectural. • Inter-RASN mobility to multicast sessions is provided through the specified RNS relocation procedure enhanced with the establishment of a short time tunnel for preventing packet loss.
