PURPOSE: A pedestrian location estimation method using a step length estimation model parameter and an apparatus for the same are provided to use the step length estimation model parameter received from a server when estimating a step length through pedestrian dead reckoning (PDR), thereby rapidly and accurately estimating the step length without an additional correction process as soon as a location request is received. CONSTITUTION: More than one sensor generates measurement information for location estimation. A location estimating auxiliary information request unit (413) requests location estimating auxiliary information from a location estimation server. A terminal based location estimation unit (417) performs location estimation using the measurement information for location estimation and the location estimating auxiliary information. The location estimating auxiliary information includes a state of a pedestrian and parameters corresponding to the state of the pedestrian. The state of the pedestrian includes more than one state of straight walking, downward walking on an inclination, upward walking on an inclination, downward walking on stairs, upward walking on stairs, straight running, downward running on an inclination, upward running on an inclination, downward running on stairs and upward running on stairs.
