Question: In a 5G network, when utilizing MBS (Media Broadcast/Multicast Service) for Mission Critical (MC) services like MCPTT, MCVideo, and MCData, what is a key consideration for the MC service server when deciding to create or use an MBS session?
Option 1: The type of UE's mobile operating system.
Option 2: The UE's MBS capabilities, location, and MBS listening status report sent by group members.
Option 3: The availability of unicast bearers in the network.
Option 4: The number of concurrent MC service groups.
Explanation: When an MC service server decides to create or use an MBS session for media transmission in Mission Critical services over a 5G system, it considers several factors related to the User Equipment (UE) and the service itself. Among these, the UE's capabilities specifically regarding MBS, its current location (which can affect signal strength and availability of services), and the MBS listening status reports from group members (indicating their readiness or ability to receive the multicast/broadcast content) are crucial. These factors directly influence the effectiveness and efficiency of the MBS session for the intended MC service group communication.
