Question: What is the specified range for the timer TR1M in a mobile radio interface, as per Point-to-Point Short Message Service (SMS) support requirements?
Option 1: Greater than 35 seconds and less than 45 seconds
Option 2: Greater than 20 seconds and less than 30 seconds
Option 3: Greater than 10 seconds and less than 25 seconds
Option 4: Greater than 50 seconds and less than 60 seconds
Explanation: The correct answer is Option 1 because, according to the specified requirements for timers in the context of Point-to-Point Short Message Service (SMS) support on the mobile radio interface, timer TR1M has a defined range to ensure efficient message handling. This range, being greater than 35 seconds and less than 45 seconds, strikes a balance between preventing overly frequent retries and minimizing delays in message delivery, thus optimizing network resource utilization and user experience.
