Procedure for defining position by means of an asynchronous cellular mobile radio system

Abstract

Abstract The procedure for defining position by means of an asynchronous cellular mobile radio system is dependent on only minor additional costs for its use. The parameters required for defining position are reported to the mobile radio terminal even while the connection is being set up, for technical radio reasons. Only minor changes are carried out in the mobile radio terminal. By evaluating range-dependent parameters which are reported continuously to the mobile radio terminal whenever a connection is set up and in order to maintain the connection, it is not only possible to identify the radio cell in which the mobile radio terminal is located, but the location accuracy can be improved down to a circular ring. Data from adjacent radio cells are included in the calculation to decide on a circular ring segment from a circular ring. <IMAGE>
