Abstract

En un sistema de comunicacion que incluye un numero de estaciones base (102, 104, 106) para atender estaciones moviles (108) presentes en el sistema, laposicion de una estacion movil durante una llamada de voz en progreso es determinada por medio dela realizacion de mediciones de tiempo o ángulo usando unasenal de posicionamiento entre la estacion movil y un numero requerido de estaciones base. Los medios (138, 152) son provistos para detectar la actividad devoz en la llamada de voz en progreso, los medios adicionales (111, 138, 152, 142) son provistos para que la voz sincronice la transmision de la senal deposicionamiento con una parte de la llamada de voz en progreso que tiene baja o nula actividad de voz.In a communication system that includes a number of base stations (102, 104, 106) to attend mobile stations (108) present in the system, the position of a mobile station during a voice call in progress is determined by means of the realization of time or angle measurements using a positioning signal between the mobile station and a required number of base stations. The means (138, 152) are provided to detect the voice activity in the voice call in progress, the additional means (111, 138, 152, 142) are provided for the voice to synchronize the transmission of the deposition signal with a part of the voice call in progress that has low or no voice activity.
