MBMS session start is the point at which the BM-SC is ready to send data. MBMS no

45、tification informs the UEs about forthcoming and about ongoing MBMS data transfer. MBMS Cell Group is 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

46、 there will be no more data to send for some period of time. Data transfer is the phase when MBMS data 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

47、 the data bearer established between SGSN and RNC to transport MBMS data MBMS radio bearer denotes the 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

48、 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 servic

49、es in MBMS Broadcast mode for which the UE applies RRC procedures to inform UTRAN that the service has been selected (by upper layers). MBMS Iu signalling connection denotes the signalling connection established between the RNC and the CN node to serve one MBMS Service Context.
