Description
ZusammenfassungSummary
Die Erfindung offenbart ein Verfahren und eine Vorrichtung, die die Lokalisierung eines mobilen Funkgerätes (MS) auf der Basis der aus einem terrestrischen Funknetz gewonnenen Daten täuscht, ohne den Telekommunikationsverkehr der MS zu beeinflussen.The The invention discloses a method and an apparatus that the Localization of a mobile radio (MS) based on the data obtained from a terrestrial radio network is deceiving, without to influence the telecommunication traffic of the MS.
Stand der TechnikState of the art
Für die Lokalisierung einer MS, z. B. nach GSM- oder UMTS-Standard, sind Verfahren auf der Grundlage der terrestrischen Ausbreitungsbedingungen bekannt. Die Lokalisierung hat, abhängig vom Verfahren, von der Anzahl der benachbarten Feststationen (BTS) und den Ausbreitungsbedingungen (z. B. Reflexionen aus der Umbebung) unterschiedliche Genauigkeit (nach dem derzeitigen Stand der Technik < 50 m mit ca. 98% Wahrscheinlichkeit). Die z. Z. bekannten terrestrischen Lokalisierungsverfahren beruhen grundsätzlich auf der Auswertung der Laufzeiten (Timing Advance, TA) der Sendesignale zwischen der MS und den erreichbaren BTS.For the localization an MS, e.g. B. according to GSM or UMTS standard, are on the basis of terrestrial propagation conditions known. The localization has, depending from the procedure, from the number of neighboring base stations (BTS) and the propagation conditions (eg reflections from the surroundings) different accuracy (according to the current state of the art <50 m with approx. 98% Probability). The z. Z. are based on known terrestrial localization methods in principle on the evaluation of the transit times (timing advance, TA) of the transmission signals between the MS and the reachable BTS.

Aufgabe der ErfindungObject of the invention
Die Lokalisierung einer MS kann, sofern das Gerät eingeschaltet ist und von mindestens drei BTS empfangen wird, ohne den Einfluss und die Einwilligung des Benutzers durchgeführt werden.The Localization of an MS, if the device is switched on and off at least three BTS is received, without the influence and consent performed by the user become.
Die Lokalisierbarkeit einer MS ist vom Benutzer aber nicht immer erwünscht.The localizability of an MS is of Users are not always welcome.

der vorliegenden Erfindung werden die TA von der MS (
Dies
ist im einfachsten Fall mit einer festen Verzögerungsleitung (
Diese simple Lösung, durch Verzögerung der TA um eine feste Zeit, kann nach den Ansprüchen 6 bis 9 und 15 bis 18 verbessert werden, da
- – Verzögerungsleitungen verlustbehaftet
sind. Es muß daher
zur Gewährleistung
der Empfindlichkeit der MS (
4 ) ein zusätzlicher bidirektionaler Verstärker (9 ) nach2 installiert werden. - – Verzögerungsleitungen im Vergleich zu handelsüblichen MS (Handys) voluminös und schwer sind. Diese Lösung wäre daher nur bei Geräten, die quasi-stationär, z. B. in Fahrzeugen, betrieben werden, praktikabel.
- - Delay lines are lossy. It must therefore be used to ensure the sensitivity of the MS (
4 ) an additional bidirectional amplifier (9 ) to2 be installed. - - Delay lines are bulky and heavy compared to commercial MS (cell phones). This solution would therefore only for devices that are quasi-stationary, z. B. in vehicles, operated, practicable.
Als vorteilhafte Ausgestaltung der Erfindung sind daher vorgesehen:
- – Digitale
Schaltkreise (
10 ) zur Verzögerung und darin integrierte Verstärker (12 ) - – Variable, steuerbare Verzögerungszeiten τ.
- - Digital circuits (
10 ) for delay and integrated amplifiers (12 ) - - Variable, controllable delay times τ.
Schaltkreise zur Verzögerung digitaler Signale sind im Prinzip als Schieberegister aufgebaut und seit langem Stand der Technik. Diese sind als kompakte Schaltkreise realisiert. Verluste können durch integrierte Verstärker kompensiert werden.circuits to delay digital signals are in principle constructed as a shift register and for a long time state of the art. These are called compact circuits realized. Losses can be through integrated amplifier be compensated.

variierende Verzögerungsänderung τ (
Mittels
eines Mikrocomputers (
Die simulierten Bewegungsprofile können fest abgespeichert oder frei programmierbar sein. Mögliche Szenarien für eine MS im Stillstand könnten sein:
- – Langsame Hin- und Her-Bewegungen (Fußgänger-Simulation)
- – Schnelle Bewegungen (Versenden einer SMS aus einem scheinbar schnell fahrenden Fahrzeug)
- – Plötzliche Beschleunigungen (Simulation eines abbremsenden Fahrzeugs)
- – zufällige, zeitliche Verzögerungszeiten (chaotisches Verhalten).
- - slow back and forth movements (pedestrian simulation)
- - Fast movements (sending an SMS from a seemingly fast moving vehicle)
- - Sudden accelerations (simulation of a decelerating vehicle)
- - random time delays (chaotic behavior).
