Abstract
Systems and methods are provided for detecting a mobility mode of a mobile device. The method, in response to receiving an observation decision, comprises finding (e.g., recursively) the most probable mobility mode state of the wireless mobile device using a dynamic programming algorithm based on a Hidden Markov Model that comprises: calculating the probability for the observation by the knowledge of the observation and probability of the previous state using the transition probability and multiplying by the emission probability of observation for the state, obtaining the maximum probability for the detected mobility mode states, determining a mobility mode state with the maximum probability, and storing the mobility mode state data of the wireless mobile device in a given FIFO queue of the one or more FIFO queues. The method future comprises controlling the output of the position data by acquiring the satellite navigation data on an interval basis.
