Question: In a Mission Critical (MC) service deployment over a 5G System, which of the following ownership scenarios is possible regarding the administration of devices across different planes?
Option 1: The PLMN operator always owns all RAN components and administers all MC service UEs.
Option 2: The MC service provider may own some RAN components within the 5GS, even if the 5GS is administered by the PLMN operator.
Option 3: An organization independent from both PLMN and MC service providers can only administer, not own, MC service UEs.
Option 4: All devices across planes (MC service, SIP core, and 5GS) must be owned and administered by a single entity.
Explanation: This option highlights a plausible scenario in MC service deployments where the ownership of RAN components can differ from the administrative entity of the 5GS. This reflects the complexity of stakeholder relationships in telecom networks, where service providers, network operators, and device owners might be distinct entities with varying responsibilities and interests. Understanding such scenarios is crucial for managing identities, signaling, and overall network security in a multi-stakeholder environment.
