Question: What does the source NG-RAN node consider when determining a target cell for handover among candidate CAG cells?
Option 1: The source NG-RAN node considers the list of CAG IDs supported by the candidate target cells and the received PNI-NPN restrictions.
Option 2: The source NG-RAN node only considers the list of CAG IDs supported by the candidate target cells.
Option 3: The source NG-RAN node only considers the received PNI-NPN restrictions.
Option 4: The source NG-RAN node does not consider any mobility restrictions.
Explanation: According to the telecom concept of handover in a CAG (Closed Access Group) scenario, the source NG-RAN node needs to ensure that the target cell is compatible with the received PNI-NPN (Public Network Identifier - Non-Public Network Identifier) mobility restrictions. This requires considering both the list of supported CAG IDs and the PNI-NPN restrictions to select a suitable target cell for handover.
