Question: Upon expiry or stop of T331 timer, what action is mandated for the User Equipment (UE) regarding VarMeasIdleConfig in an E-UTRA network?
Option 1: Release the VarMeasIdleConfig
Option 2: Suspend the VarMeasIdleConfig temporarily
Option 3: Continue with the existing VarMeasIdleConfig settings
Option 4: Initiate an immediate handover to a different RAT (Radio Access Technology)
Explanation: Upon the expiry or stop of the T331 timer, the UE is required to release the VarMeasIdleConfig, as part of managing resources efficiently in idle mode. The other options are incorrect because suspending, continuing with existing settings, or initiating a handover are not mandated actions for this specific scenario.
