MBMS is a point-to-multipoint service in which data is transmitted from a single source entity to multiple recipients. Transmitting the same data to multiple recipients allows network resources to be shared. The MBMS bearer service offers two modes:
  • Broadcast Mode;
  • Multicast Mode.
Broadcast Mode is supported for EPS and GPRS, and Multicast Mode is supported for GPRS. MBMS for EPS supports E-UTRAN and UTRAN. MBMS for GPRS supports UTRAN and GERAN.

MBMS architecture enables the efficient usage of radio-network and core-network resources, with an emphasis on radio interface efficiency.
