46、start 1stsession stop Service 1 Session 2 Service 1 session 1 Service 1 events Figure 3.1: MBMS Timeline, based on 4. MBMS session start is the point at which the BM-SC is ready to send data. MBMS notification informs the UEs about forthcoming and about ongoing MBMS data transfer. MBMS Cell Group is

47、 a group of multiple cells belonging to one RNS and sharing one PDCP and RLC entity to utilize p-t-m transmission of the MBMS Service MBMS session stop is the point at which the BM-SC determines that there will be no more data to send for some period of time. Data transfer is the phase when MBMS dat

48、a are transferred to the UEs. MBMS service availability is the phase between start of service announcement and the end of the last session or stop of service announcement. MBMS Iu data bearer denotes the data bearer established between SGSN and RNC to transport MBMS data MBMS radio bearer denotes th

49、e data bearer established between RNC and UE(s) to transport MBMS data MBMS RAB denotes both, the MBMS Iu data bearer and the MBMS radio bearer MBMS Service Context contains the necessary information for the UTRAN to control the MBMS Service in UTRAN. MBMS Activated Services: a set of services made up of those in MBMS multicast mode that the UE has joined as well as those in MBMS broadcast mode that the UE is interested in receiving. MBMS Selected Services: a subset of the MBMS activated services in MBMS Broadcast mode for which the UE app
