Question: In idle mode, what determines the maximum interval at which a terminal sends STATUS commands to the UICC when the extended DRX cycle bit in the EFAD is set to 1?
Option 1: Only the interval negotiated with the UICC (USIM Application Toolkit)
Option 2: Only the extended idle mode DRX cycle received from the network
Option 3: The maximum between the interval negotiated with the UICC (USIM Application Toolkit) and the extended idle mode DRX cycle received from the network
Option 4: A fixed interval defined by the terminal's manufacturer
Explanation: This is because, according to specifications, when the extended DRX cycle bit in the EFAD is set to 1, the terminal must use the maximum of two values to determine the sending interval for STATUS commands: the negotiated interval with the UICC and the network-provided extended idle mode DRX cycle, ensuring flexibility while maintaining a cap on the maximum interval based on network conditions.
