Question: Which of the following statements is true regarding the usage of MBMS (Multimedia Broadcast Multicast Services) bearers for Mission Critical (MC) services?
Option 1: A single MBMS bearer can only be used by one MC service within a single group at a time.
Option 2: MBMS bearers are exclusively reserved for MCPTT (Mission Critical Push To Talk) and cannot be used by other MC services.
Option 3: A single MBMS bearer can be utilized by one or more MC services within a single group, or by multiple group communications in parallel.
Option 4: Each MC service type (e.g., MCPTT, MCVideo, MCData) requires a dedicated, separate MBMS bearer.
Explanation: This is correct because a single MBMS bearer has the flexibility to support one or more MC services within the same group simultaneously, or even facilitate communications across multiple groups at the same time, optimizing network utilization for critical communications.
