Embodiment Construction

[0029] figure 1 A table is shown in which, for each cell, pairs of values ​​are stored, where each pair reproduces the received field strength when the connection was established and the distance parameters transmitted there. In fact, for a more thorough understanding, the distance parameter is converted to the distance from the mobile wireless user to the sending station of the corresponding cell. In a GSM network this distance parameter is a timing advance parameter, whereas in a UMTS network this distance parameter is a propagation delay parameter. The invention is of course also applicable to other network standards if parameters are also transmitted there, from which the distance between the mobile radio subscriber and the active transmitting station can be inferred.

[0030] Preferably, this table is created in a locating device according to the invention, which is connected to the outermost node in the network before the air interface, for passive monitoring e.g. in a ba...

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 leastone 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 pointsatisfying the distance parameter(s) read-out in step b).

Description

technical field [0001] The invention relates to a method for locating at least one mobile radio subscriber in a mobile radio network, wherein said mobile radio network comprises at least the following characteristics: the smallest addressable unit is a cell, wherein a sending station is associated with each cell; at least when establishing a connection, determine information about reception field strength and parameters related to the distance of the mobile radio user to the transmitting station of the active cell; with and / or without an active mobile radio link, the mobile radio The user sends at least one measurement report, wherein an itemisation is provided in the measurement report, the measurement report comprising at least two transmitting stations, wherein each transmitting station is assigned a value related to the received field strength of the signal from this transmitting station. Furthermore, the invention relates to a corresponding positioning device and a comput...
