Option 1: Remove dedicated radio resources related to the UE Context.
Option 2: Initiate release of common user plane resources involved in the UE context.
Option 3: Maintain the RRC (Radio Resource Control) connection to preserve signaling channels.
Option 4: Release the RRC connection if possible.
Explanation: According to the specified actions for a DRNC during UE Context termination, maintaining the RRC connection is not listed as a required action.
