Method and locating device for locating at least one mobile radio subscriber
First Claim
1. A method for locating at least one mobile radio subscriber in a mobile radio network, wherein the mobile radio network includes at least the following characteristics:
- the smallest addressable unit is a cell, wherein a transmitting station is associated with each cell;
at least upon connection setup, information about the receive field strength and a parameter correlated with the distance of the mobile radio subscriber to the transmitting station of the active cell is determined;
with and/or without active mobile radio link, a mobile radio subscriber transmits at least once a measurement report, wherein an itemization is provided in the measurement report, which includes at least two transmitting stations, wherein to each transmitting station a value correlated with the receive field strength of a signal from this transmitting station is allocated;
the method comprising;
creating a table per cell based at least in part upon the determined information and in which at least one distance parameter to the transmitting station of the cell is allocated to the respective receive field strengths;
for at least one value correlated with the receive field strength and transmitted in the measurement report, reading out, from the table, the allocated distance parameter to the transmitting station of the respective cell;
determining at least one point satisfying the distance parameter(s), wherein after a connection abort, based on distance parameters determined from a last transmitted measurement report, the allocated distance parameters to at least two transmitting stations are determined for the time (tCA) of the connection abort by extrapolation.

Abstract
The present invention relates to a method for locating at least one mobile radio subscriber in a mobile radio network, wherein to each transmitting station a value correlated with the receive field strength of a signal from this transmitting station is allocated; including the following steps: a) from the information determined upon connection setup, a table is created per cell, in which at least one distance parameter to the transmitting station of the cell is allocated to the respective receive field strengths; b) for at least one value correlated with the receive field strength and transmitted in the measurement report, the allocated distance parameter to the transmitting station of the respective cell is read out from the table created in step a); and c) determining at least one point satisfying the distance parameter(s) read-out in step b).

1. A method for locating at least one mobile radio subscriber in a mobile radio network, wherein the mobile radio network includes at least the following characteristics:
-
the smallest addressable unit is a cell, wherein a transmitting station is associated with each cell; at least upon connection setup, information about the receive field strength and a parameter correlated with the distance of the mobile radio subscriber to the transmitting station of the active cell is determined; with and/or without active mobile radio link, a mobile radio subscriber transmits at least once a measurement report, wherein an itemization is provided in the measurement report, which includes at least two transmitting stations, wherein to each transmitting station a value correlated with the receive field strength of a signal from this transmitting station is allocated; the method comprising; creating a table per cell based at least in part upon the determined information and in which at least one distance parameter to the transmitting station of the cell is allocated to the respective receive field strengths; for at least one value correlated with the receive field strength and transmitted in the measurement report, reading out, from the table, the allocated distance parameter to the transmitting station of the respective cell; determining at least one point satisfying the distance parameter(s), wherein after a connection abort, based on distance parameters determined from a last transmitted measurement report, the allocated distance parameters to at least two transmitting stations are determined for the time (tCA) of the connection abort by extrapolation. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8)
