Abstract
The invention relates to a method for locating a mobile station (1) by means of the mobile station (1) and a location service center (LSC) (5) in the mobile network by dynamically distributing the computing between these two. Preferably the mobile station (1) measures impulse responses of received bursts to determine time differences, and preprocesses measurement results. The location service center (5) performs the final processing. According to the invention, dummy bursts are also used in the locating process. The method also includes an automatic locating procedure activated in conjunction with an emergency call.
