M3AP – M3 Application Protocol
M3AP is used in support of eMBMS (Evolved Multimedia Broadcast Multicast Services) and is found on the M3 reference point, located between the MME and eNB (specifically the Multicell/Multicast Coordination Entity). The main role of M3AP is the support of MBMS Session Management, ensuring that the MCEs within the eNB are provided with the correct information to enable them to receive an MBMS service from the core network. In turn, the MCE will use information provided in M3AP messages to correctly establish the required radio resources.
