System Information Block 2 and System Information Block 13 carries MBMS related information.
SIB2 mainly contains generic information like MBSFN subframes information . This information helps to UE where to look into spectrum for MBMS services.


SystemInformationBlockType2 ::= SEQUENCE {

Can anyone please explain MBSFN synchronization Area ,MBSFN area and MBSFN service area ?
How they are mapped to each other ?

When BMSC server initiates a service to broadcast, it provides service Id using the TMGI (temporary mobile group Id) and the area i.e MBMS service area. Once MME forwards this information to MCE, how MCE maps this received MBMS service area to MBSFN Area(s) ? How MCE decides on MCCH related BCCH configuration during the M2 Setup request ? In M2 setup request, eNodeB sends the list of serving MBMS service areas per cell to MCE but how MCE decides which cell is going to be part of a particular MBSFN Area. ?
