Question: In a Shared MBMS Network (SMN) over E-UTRAN, which of the following statements about the deployment of RAN nodes for MBMS bearer service is accurate?
Option 1: RAN nodes (eNBs/MCEs) dedicated to MBMS bearer service cannot be shared among participating PLMNs.
Option 2: Dedicated RAN nodes for MBMS are not allowed in an SMN setup, requiring only shared general-purpose RAN nodes.
Option 3: The deployment of dedicated RAN nodes for MBMS bearer service within an SMN does not necessitate any specific MME configuration.
Option 4: Dedicated RAN nodes (eNBs/MCEs) for MBMS bearer service may be deployed as part of the SMN, requiring a shared MME function.
Explanation: This is correct because dedicated RAN nodes (like eNBs or MCEs) for MBMS bearer service can be part of the SMN, but this setup requires using a shared MME function to ensure seamless coordination and management across participating PLMNs within the shared network infrastructure.
