Abstract:
1. A method of reducing energy consumption of a mobile device that operates intermittently with extended periods of application data traffic inactivity between intermittent application data traffic operations, comprising the steps of: said mobile device monitoring application data traffic operation of said mobile device to detect periods of application data traffic inactivity; said mobile device storing a distribution of inactivity period durations; said mobile device predicting the duration of a detected period of application data traffic inactivity by calculating a probability of inactivity period duration based on said stored distribution by solving the following equation: Wherein Pto(s) is the probability that a residual silent period of inactivity is given that a silent period of to has already occurred inactivity; and said mobile device turning off power to said device for a period of time substantially corresponding to said predicted duration.
