Problems solved by technology

The main disadvantage of the "cell fingerprint" method is that the update of the "cell fingerprint" needs to be done by changing the cell configuration by the network operator, which currently can only be done manually by the user of the mobile wireless terminal device, where the user normally has to Notifications of changes to the network configuration by the mobile wireless operator; typically the user notices the change when his mobile wireless terminal device does not automatically relocate to its own home base station
[0014] The main disadvantage of this prior art is that changes in the macro cell network configuration in the environment where the local base station is located will not cause a search for the local base station, because the "cell fingerprint" used for the search is not found

Embodiment Construction

[0036] If the mobile wireless terminal device 101, for example, stores the information of the six cells of the macro cell network 110 geographically near its own local base station 100 as a "cell fingerprint" with a cell identifier (CI) and a tracking area identifier (TAI) (in In the case of E-UTRAN, otherwise in the case of UMTS or GSM corresponding area information such as location area (LA)), the cell layout triggers the mobile radio terminal to search for its own local base station 100 as follows:

[0037] A typical "cell fingerprint" in the surrounding environment of the local base station itself:

[0038] CI=00001TAI=00001

[0039] CI=00002TAI=00001

[0040] CI=00003TAI=00001

[0041] CI=00004TAI=00001

[0042] CI=00005 TAI=00002

[0043] CI=00006 TAI=00002

[0044] The method used according to the current state of the art is based on statistical probabilities, within a cellular mobile radio system (PLMN) this cell layout is one-time (or at least again precisely at ...

Abstract

A method for the geographical location of a mobile radio terminal device within a cellular mobile radio network, wherein each cell of the mobile radio network is identifiable by means of an identification comprising a cell identification and an area identification, wherein the identification is transmitted and the mobile radio terminal means adapted to receive and process such identities and to store one or more identities, wherein the geographical positioning of the mobile radio terminal device within the cellular mobile radio network is performed by comparing the currently received identities with one or more stored identities , wherein, when the cell identity and / or area identity of the cell is changed, the additional information is transmitted to the mobile wireless terminal device, and the new identity is stored instead of the old identity.

Description

technical field [0001] The invention relates to a method for geolocating a mobile radio terminal within a cellular mobile radio network, wherein each cell of the mobile radio network is identifiable by means of an identification comprising a cell identification and an area identification, wherein the identification is transmitted, and wherein The mobile radio terminal device is adapted to receive and process such identifications and to store one or more identifications, wherein the geographical location of the mobile radio terminal device within the cellular mobile radio network is determined by combining the currently received identification with one or more stored Identifiers are compared to implement. [0002] In particular, the present invention relates to a method or device for realizing terminal-based optimal search functions of mobile radio terminal devices in cellular mobile radio systems, e.g. according to GERAN, UTRAN, E-UTRAN, cdma2000, UMB, WiAMX, etc. To find ava...
