The objective of this Technical Report is to study and specify potential modifications to the MBMS/GCSE_LTE architectures and/or procedures as specified in TS 23.246 [2] and TS 23.468 [3] to enable the following improvements and enhancements:
1. to allow the establishment of MBMS bearers using target area information, as distinct from using an MBMS Service Area;
2. to MBMS congestion handling;
3. if seen to be needed, to possible MBMS roaming scenarios;
4. as required by the MCPTT application work.
