    varying the predetermined intervals and monitoring the lengths of several periods of inactivity at which the mobile radio network disconnects the IP connection;

    based on the several monitored lengths of periods of inactivity, determining a maximum interval between keep-alive messages such that the maximum interval meets a predetermined criterion of statistical confidence; and

    setting the interval between keep-alive messages to the maximum interval.
