Question: What action does a User Equipment (UE) take when indicated that its Global Navigation Satellite System (GNSS) position is out-of-date while in Radio Resource Control (RRC) CONNECTED state?
Option 1: Perform actions as specified for leaving RRC_CONNECTED with a release cause 'other', and then re-establish RRC connection.
Option 2: Immediately update the GNSS position without altering the current RRC state.
Option 3: Enter RRC_IDLE state directly without performing any additional actions.
Option 4: Ignore the indication if data transmission is in progress.
Explanation: When a UE receives an indication that its GNSS position is out-of-date while in RRC_CONNECTED, it follows the protocol to ensure seamless network management. The correct procedure involves performing the actions as if leaving the RRC_CONNECTED state (which includes necessary cleanup and resource release) with a specified release cause ('other' in this context), allowing for potential re-establishment or other subsequent actions based on network or UE needs. This ensures resource optimization and maintains connectivity integrity.
