Question: In AMPS and TIA/EIA-41 based networks, what happens to the CALL COUNT value stored in the SIM during a call, upon receiving a specific command from the network?
Option 1: The CALL COUNT value remains unchanged.
Option 2: The CALL COUNT value is incremented by 1 using the INCREASE command.
Option 3: The CALL COUNT value is reset to its initial state ('00 00 00').
Option 4: The CALL COUNT value is decremented by 1.
Explanation: In AMPS and TIA/EIA-41 based systems, the network can modify the SIM's CALL COUNT during a call. Specifically, upon issuing an INCREASE command to the SIM, the CALL COUNT value is incremented by 1, used for tracking or authentication purposes, highlighting the dynamic interaction between the SIM and the network in managing this parameter.
