Abstract

The invention is based on the object of carrying out position determination from a mobile radio station in order that the result of the position determination is passed on to stationary radio stations only with the agreement of the user. In addition, the technical complexity for the implementation of the method is intended to be as low as possible. The object is achieved in that the mobile radio station (M) buffer stores data messages (DF1, DF2, DF3), which have been received from at least three stationary radio stations (F1, F2, F3), in a computer (C) in the mobile radio station. The instantaneous location is then determined by the computer using the propagation time differences ( DELTA t1, DELTA t2, DELTA t3) between the transmission of the respective data messages and the reception of these data messages, and locations, stored in the computer of the stationary radio stations. A preferred field of application for the method according to the invention is the German Federal Post Office OemL Network C. The drawing shows the time sequence of transmission and reception of the data messages. <IMAGE>

Description

Beschreibung eines AusführungsbeispielsDescription of an embodiment

Ein Ausführungsbeispiel ist in der Zeichnung anhand mehrerer Figuren dargestellt und wird im folgenden näher erläutert. Es zeigenAn embodiment is in the drawing based on several figures shown and is explained in more detail below. Show it

Fig. 1 einen Ausschnitt aus einem in Funkzellen aufgeteilten Funknetz, Fig. 1 a section of a divided radio cells in the radio network,

Fig. 2 den zeitlichen Ablauf der Aussendung von Datentelegrammen der ortsfesten Funkstationen und Fig. 2 shows the timing of the transmission of data telegrams from the fixed radio stations and

Fig. 3 den zeitlichen Verlauf des Empfangs der Datentelegramme nach Fig. 2. Fig. 3 shows the time course of the reception of the data telegrams of FIG. 2.

Das in Fig. 1 nur ausschnittweise dargestellte Funknetz umfaßt meh­ rere Funkzellen Z 1 . . . Z 5. Zu jeder Funkzelle gehört eine ortsfeste Funksende- und -empfangsstation, im folgenden ortsfeste Funkstation F 1 . . . F 5 genannt. Innerhalb des Funknetzes operieren mobile Funk­ sende- und -empfangsstationen, im folgenden mobile Funkstationen genannt, von denen in Fig. 1 nur eine mobile Funkstation M gezeigt ist, die sich angenommenerweise gerade in der Funkzelle Z 1 aufhält.The radio network shown only in sections in Fig. 1 comprises several radio cells Z 1 . . . Z 5 . Each radio cell has a fixed radio transmission and reception station, hereinafter referred to as a fixed radio station F 1 . . . F 5 called. Mobile radio transmitting and receiving stations operate in the radio network, hereinafter referred to as mobile radio stations, of which only one mobile radio station M is shown in FIG. 1, which is assumed to be currently in the radio cell Z 1 .

Zwecks Ermittlung des augenblicklichen Standortes der mobilen Funk­ station M werden folgende Maßnahmen ergriffen.The following measures are taken to determine the current location of the mobile radio station M.

Die ortsfesten Funkstationen F 1 . . . F 5 senden nach einem Zeitschlitz­ verfahren mit vorgegebenem Zeitrahmen zu festen Zeitpunkten t g 1, t g 2 . . . t gn periodisch Datentelegramme D F 1, D F 2 . . . D Fn aus; vgl. Fig. 2. Diese Datentelegramme sind für jede ortsfeste Funkstation F 1, F 2 . . . individuell gekennzeichnet.The fixed radio stations F 1 . . . F 5 transmit according to a time slot with a predetermined time frame at fixed times t g 1 , t g 2 . . . t gn periodic data telegrams D F 1 , D F 2 . . . D Fn off; see. Fig. 2. These data telegrams are for each fixed radio station F 1 , F 2 . . . individually marked.

Jede Mobilstation, zum Beispiel M, enthält einen mit ihrem Empfangs­ teil E verbundenen Datentelegrammauswerter A sowie, falls die mobile Funkstation mit Mitteln zur Standortermittlung ausgerüstet ist, einen Rechner C. Zu dem Rechner C gehört auch ein elektronischer Speicher, in welchem die Standorte aller ortsfesten Funkstationen zusammen mit ihren individuellen Kennzeichen tabellarisch abgespeichert sind.Each mobile station, for example M, contains a data telegram evaluator A connected to its receiving part E and, if the mobile radio station is equipped with means for determining location, a computer C. The computer C also includes an electronic memory in which the locations of all fixed radio stations are stored in a table together with their individual characteristics.

Empfängt die mobile Funkstation M zu einem Zeitpunkt t 1 (Fig. 3) ein Datentelegramm D F 1 der ersten ortsfesten Funkstation F 1, so entspricht die zeitliche Differenz zwischen den Zeitpunkten t 1 und t kg 1 der Lauf­ zeitdifferenz Δ t1, mit der das zum Zeitpunkt t g 1 ausgesendete Daten­ telegramm D F 1 bei der mobilen Funkstation M eintrifft. Das von der mo­ bilen Funkstation M empfangene Datentelegramm D F 1 wird in dem Speicher des Rechners gespeichert. Empfängt die mobile Funkstation M anschlie­ ßend zum Beispiel ein Datentelegramm D F 2 der ortsfesten Funkstation F 2 und danach ein Datentelegramm D F 3 der ortsfesten Funkstation F 3, so weisen auch diese Datentelegramme je eine Laufzeitdifferenz Δ t2, Δ t3 gegenüber den Zeitpunkten t g 2 und t g 3 der Aussendung der Datentele­ gramme auf, wobei wegen der verschiedenen Abstände der ortsfesten Funk­ stationen von der mobilen Funkstation M Δ t 2 < Δ t 1 und Δ t 3 < Δ t 2 ist. If the mobile radio station M receives a data telegram D F 1 of the first fixed radio station F 1 at a time t 1 ( FIG. 3), the time difference between the times t 1 and t kg 1 corresponds to the running time difference Δ t 1 with which the data telegram D F 1 sent at time t g 1 arrives at the mobile radio station M. The data telegram D F 1 received by the mobile radio station M is stored in the memory of the computer. If the mobile radio station M subsequently receives, for example, a data telegram D F 2 from the fixed radio station F 2 and then a data telegram D F 3 from the fixed radio station F 3 , these data telegrams also each have a transit time difference Δ t 2, Δ t 3 compared to the times t g 2 and t g 3 of the transmission of the data telegrams, with because of the different distances of the fixed radio stations from the mobile radio station M Δ t 2 < Δ t 1 and Δ t 3 < Δ t 2.

Aus den Laufzeitdifferenzen Δ t 1, Δ t 2 und Δ t 3 und den bekannten Stand­ orten der ortsfesten Funkstationen F 1, F 2 und F 3 berechnet der Rechner C nach den Regeln der Trigonometrie den Standort der mobilen Funkstation M. Das Ergebnis der Berechnung, das heißt der augenblickliche Standort der mobilen Funkstation M, wird dem Benutzer der mobilen Funkstation vorzugs­ weise mittels eines Displays angezeigt. Vorausgesetzt wird bei der Stand­ ortbestimmung, daß jeweils mindestens drei Datentelegramme von drei ver­ schiedenen ortsfesten Funkstationen empfangen werden.From the time differences Δ t 1, Δ t 2 and Δ t 3 and the prior locations of the fixed radio stations F 1, F 2 and F 3 calculates the computer C according to the rules of trigonometry the location of the mobile radio station M. The result of the calculation, that is, the current location of the mobile radio station M , is preferably shown to the user of the mobile radio station by means of a display. It is a prerequisite for the location determination that at least three data telegrams are received from three different stationary radio stations.
