LTE Broadcast, MBMS, and Group Delivery Procedures
LTE broadcast, MBMS, and group delivery procedures show how a UE receives system information, public warning messages, and point-to-multipoint service data. Use this hub to jump into system information acquisition, MIB and SIB acquisition, ETWS, CMAS, MBMS counting, MBMS interest indication, MBMS PTM bearer, and SC-PTM call flows.

What This Covers
LTE broadcast procedures deliver system information and public warning content without a dedicated point-to-point session.
MBMS and SC-PTM procedures support group delivery, interest reporting, counting, and point-to-multipoint bearer behavior.
