LTE MBMS: What is the specification number for interface between MCE and eNodeB ?

Question

There is a choice either one or four consecutive radio frames can be used for MBMS transmission. I want to know the parameter on which number of radio frames come out ?

Answer 1

As of now I have very limited knowledge of M2 interface. M2 interface exists between eNodeB and MCE i.e. Multi-cell co-ordination entity. M2 interface is a reliable interface. Similar to S1-AP protocol, M2-AP protocol uses the SCTP as a transport layer. M2-AP protocol uses port no. 36433 defined by IANA.
