1. , for estimating a method for the position of mobile device, it comprises:

  • The signal received based on described mobile device place at least in part measures the distance between described mobile device and transmitter;

    Combined by one or more previous measurement of described mobile device by the measurement result of described distance and described distance, to provide the estimated result of described distance;

    AndDescribed estimated result is transferred to location-server from described mobile device;

    Wherein, the described distance of described measurement comprises measures described distance based on the intensity of the described signal received at least in part,The described distance of wherein said measurement comprises the pseudo range determining described transmitter further, describedly determines to comprise further to the pseudo range of described transmitter;

    Be based, at least in part, on the signal that described mobile device place receives, obtain the first original virtual range measurements at described mobile device place;

    Described first original virtual range measurements is upgraded, to obtain the first estimation pseudo range at very first time example;

    The signal that second time that was based, at least in part, on receives at described mobile device place, obtains the second original virtual range measurements at described mobile device place;

    Described second original virtual range measurements is upgraded, to obtain the second estimation pseudo range in the second time instance;

    AndExtrapolate one or more described very first time example described first estimate pseudo range and described second time instance described second estimate pseudo range, with obtain shared time instance through extrapolation estimation pseudo range.
