9 Out-of-band Broadcast
Broadcast Channel Broadcast Network Content Transmitter BTS / Node B Cellular Network (GSM/GPRS/3G) Reverse / Interactivity Channel Interaction Processing and Subscriber Management / Charging System Interface Colombo, Sri Lanka, 7-10 April 2009

10 Choice of Technology Mode /Technology Typical Applications
Merit Profile Streaming (GPRS  LTE) On-demand Media retrieval Real-time P2P Datacasting Taxing on the cellular access network Less costly Roaming possible Reliable delivery through FLUTE & file-repair procedure for data casting (MBMS only) MBMS (3G  LTE) Media delivery (short duration – push) P2P and P2MP Datacasting Broadcast Technologies (DVB-H, MediaFLO, 1 Seg, T/S-DMB) Media delivery (long duration / continuous) Infotainment No capacity impact on cellular network Requires an overlay broadcast network No roaming Colombo, Sri Lanka, 7-10 April 2009

12 Multimedia Broadcast Multicast Service (MBMS)
MBMS defined in 3GPP as “a point-to-multipoint (PTM) downlink bearer service for IP data in the PS domain” offering high speed data rates up to 256 kbit/s MBMS Features and Services Efficient use of Radio & Core Network Resources PTM Broacasting and Multicasting Capability Different QoS for each Media Session Error protection (ex. interference, cell changes etc.) Synchronization between media sessions Service Interworking (MBMS with e.g. MMS etc) Streaming over RTP / SRTP Download over FLUTE Colombo, Sri Lanka, 7-10 April 2009

13 MBMS over 2G/3G UMTS/HSDPA
Elements needing upgrades SGSN / GGSN UTRAN / GERAN User Equipment New Network Elements BM-SC (Broadcast Multicast Service Centre) Existing Network Limitations Per user GTP tunnels for multicast content Inefficient use of radio resources Cell broadcast – low bit rate services only Enhancements from MBMS New multicast transport channel defined PTM transport over HSDPA Intelligent switching to and from PTP PTM modes Colombo, Sri Lanka, 7-10 April 2009 Ref: 3GPP TS

14 MBMS over 3G LTE Improvements offered by eMBMS
Better performance from OFDM SFNs Combining from synchronized cells Increased throughput from higher data rates Reduced interference, increased receive power Carrier sharing for broadcast/multicast and unicast is more practical 7kHz sub-carrier defined for eMBMS Colombo, Sri Lanka, 7-10 April 2009 Ref: 3GPP TS
