Question: In a GPRS network, what characterizes the RRC (Radio Resource Control) Idle mode between a Mobile Station (MS) and the Iu mode RAN?
Option 1: A dedicated RRC connection is established, with signaling for mobility handled by handover procedures.
Option 2: No RRC connection is established; the MS receives only system information and potential paging messages on a broadcast channel.
Option 3: The MS is in a state of URA Connected, utilizing dedicated radio resources for communication.
Option 4: Cell update procedures are continuously used to track the MS's position at the cell level.
Explanation: In RRC Idle mode, there is no established connection between the MS and the Iu mode RAN. The only communications are system information broadcasts from the RAN and possible paging messages for the MS on a broadcast channel, with no dedicated resources allocated or stored MS information in the RAN. This highlights how Idle mode conserves resources by minimizing interactions until an active connection is needed.
