Abstract

"MéTODO E EQUIPAMENTO PARA DETERMINAR A POSIçãO DE UM TELEFONE CELULAR". Um método e um equipamento para determinar a posição (116) de uma estação remota, tal como um telefone celular móvel, usando medições de retardo relativo e alcance absoluto. Mais particularmente, a invenção determina a posição de uma estação remota (116) usando uma combinação de medições de ligação enviada efetuadas na estação remota (116) e medições de ligação de retorno efetuadas em uma ou mais estações base (106, 108). Tais medições são usadas para efetuar cálculos que propiciam a posição da estação remota (116). Um equipamento efetuando os cálculos pode usar informações a priori sobre a localização exata de todas as estações base participantes na determinação da localização da unidade móvel, bem como calibragens de retardos inerentes associados às estações base."METHOD AND EQUIPMENT TO DETERMINE THE POSITION OF A MOBILE PHONE". A method and equipment for determining the position (116) of a remote station, such as a mobile cell phone, using measurements of relative delay and absolute range. More particularly, the invention determines the position of a remote station (116) using a combination of forward link measurements taken at the remote station (116) and return link measurements taken at one or more base stations (106, 108). Such measurements are used to perform calculations that provide the position of the remote station (116). A device performing the calculations can use a priori information about the exact location of all participating base stations in determining the location of the mobile unit, as well as inherent delay calibrations associated with the base stations.
