Question: In a 5G network utilizing Multicast-Broadcast Service (MBS) for mission critical services, how do User Equipment (UEs) receive broadcast MBS sessions in terms of their Radio Resource Control (RRC) state?
Option 1: Only when in RRC-CONNECTED state
Option 2: Only when in RRC-INACTIVE or RRC-CONNECTED states
Option 3: Irrespective of their RRC state, but with limitations for multicast sessions
Option 4: Regardless of their RRC state (i.e., connected, inactive, or idle)
Explanation: According to the architectural aspects of MC services using MBS in 5G systems, UEs can receive broadcast MBS sessions irrespective of their RRC state, which includes connected, inactive, or idle states. This capability is crucial for mission-critical communications, ensuring that emergency broadcasts can reach users under all circumstances.
