Method for non-cooperative position determination of subscribers in a power controlled mobile radio system

摘要

The invention relates to a method for non-cooperative location of a subscriber mobile station (MS) in a power-regulated mobile radio system, in which the at the subscriber mobile station (MS) radiated power is controlled such that at a base station (BS) of the mobile radio system receivable performance (from the subscriber mobile station corresponds to MS) emitted signal a predetermined fixed reception target level. It has the following steps: e) there is a database provided stored in the following information: Position of the base station (BS) of the subscriber to be located mobile station (MS); Target reception level to a base station (BS) receivable power; Information for determining the local propagation attenuation of the electromagnetic radiation; f) (by means of precisely a reconnaissance station AS) the simultaneous measurement of the bearing angle of the subscriber mobile station (MS) and the (in the clarification station AS) receivable power of the subscriber mobile station (MS) emitted signal, g) (in the elucidation station AS), a calculation of the locus of possible positions of the subscriber mobile station (MS) based on the measured reception power and with recourse to the stored information in the database, h) in the reconnaissance station is a location of the subscriber mobile station (MS) by cutting the Peilstrahls determined from bearing with the calculated locus curve of possible positions of the subscriber mobile station (MS).
