Method and locating device for locating at least one mobile radio subscriber
The present invention relates to a method for locating at least one mobile radio subscriber in a mobile radio network. The mobile radio subscriber transmits a measurement report that includes an itemization identifying at least two transmitting stations. A value correlated with the receive field strength of a signal from the transmitting stations is allocated to each transmitting station. A table is organized according to geographic units of a presettable area. A pre-calculated value correlated with the receive field strength of a signal from a transmitting station is allocated to each transmitting station. The transmitting stations are organized according to the values correlated with the receive field strength of the signal from the respective transmitting station. The location of the mobile radio subscriber is determined based on the geographic unit meeting at least one presettable criterion.
