Mobile telecommunications device position location involves determining time of arrival of signals from several mobile communications devices associated with unit of radio network

摘要

The method involves sending at least one signal from or to the device whose position is to be determined. Several mobile telecommunications devices associated with a unit of the radio network send similar signals that are received by mobile telecommunications devices associated with this unit after a signal transition time. The position of the receiving mobile telecommunications devices is determined by determining the time of arrival of signals. Independent claims are also included for the following: a mobile radio network with fixed telecommunications devices, especially transmitter stations, and mobile telecommunications devices, especially mobile telephones, mobile Internet access devices or vehicles with mobile fax machines
