Question: When updating MBS resources for group communications in a 5G system, what factors may prompt the MC Service Server to modify existing MBS sessions?
Option 1: Only changes in User Equipment (UE) location within the service area.
Option 2: Exclusively alterations in Quality of Service (QoS) requirements for the multicast session.
Option 3: A combination of emerging needs, including updates to service requirements (e.g., QoS profile), adjustments to service area related parameters, or changes in multicast MBS session activity status.
Option 4: Solely the addition of new User Equipment (UE) to the multicast group.
Explanation: In managing Mission Critical Services over a 5G system, flexibility is key. The MC Service Server must adapt to various changing conditions to ensure seamless and effective communication. This includes not just tweaks in service quality expectations (QoS) or the geographical span of the service area, but also responding to shifts in the activity status of ongoing multicast sessions. Thus, the most comprehensive and accurate response encompasses all these potential triggers for updating MBS resources.
