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 prepocesses 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.
La présente invention concerne un procédé de localisation d'une station mobile (1) faisant appel à une répartition dynamique du calcul entre une station mobile (1) et un centre de service de localisation (LSC) (5) du réseau mobile. De préférence, la station mobile (1) mesure les réponses impulsionnelles des rafales reçues afin de déterminer les différences de temps et elle prétraite les résultats des mesures. Le centre de service de localisation (5) effectue le traitement final. Selon la présente invention, les rafales fictives sont également prises en considération dans le processus de localisation. Le procédé de la présente invention comprend également une procédure de localisation automatique activée par un appel d'urgence.
