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 Z1 . . . Z5. Zu jeder Funkzelle gehört eine ortsfeste Funksende- und -empfangsstation, im folgenden ortsfeste Funkstation F1 . . . F5 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 Z1 aufhält.The radio network shown only in sections in Fig. 1 comprises several radio cells Z1. . . Z5. Each radio cell has a fixed radio transmission and reception station, hereinafter referred to as a fixed radio station F1. . . Called F5. 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 .
Zwecks Ermittlung des augenblicklichen Standortes der mobilen Funk­ station M werden folgende Maßnahmen ergriffen.To determine the current location of the mobile radio station M the following measures are taken.
Die ortsfesten Funkstationen F1 . . . F5 senden nach einem Zeitschlitz­ verfahren mit vorgegebenem Zeitrahmen zu festen Zeitpunkten tg1, tg2 . . . tgn periodisch Datentelegramme DF1, DF2 . . . DFn aus; vgl. Fig. 2. Diese Datentelegramme sind für jede ortsfeste Funkstation F1, F2 . . . individuell gekennzeichnet.The fixed radio stations F1. . . F5 transmit according to a time slot with a predetermined time frame at fixed times t g1 , t g2 . . . t gn periodic data telegrams D F1 , D F2 . . . D Fn off; see. Fig. 2. These data telegrams are for each fixed radio station F1, F2. . . 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 one with its reception Part E connected data telegram evaluator A and, if the mobile Radio station is equipped with means for determining location, one Computer C. Computer C also includes an electronic memory, in which the locations of all fixed radio stations together with their individual characteristics are stored in a table.
Empfängt die mobile Funkstation M zu einem Zeitpunkt t₁ (Fig. 3) ein Datentelegramm DF1 der ersten ortsfesten Funkstation F1, so entspricht die zeitliche Differenz zwischen den Zeitpunkten t₁ und tg1 der Lauf­ zeitdifferenz Δt1, mit der das zum Zeitpunkt tg1 ausgesendete Daten­ telegramm DF1 bei der mobilen Funkstation M eintrifft. Das von der mo­ bilen Funkstation M empfangene Datentelegramm DF1 wird in dem Speicher des Rechners gespeichert. Empfängt die mobile Funkstation M anschlie­ ßend zum Beispiel ein Datentelegramm DF2 der ortsfesten Funkstation F2 und danach ein Datentelegramm DF3 der ortsfesten Funkstation F3, so weisen auch diese Datentelegramme je eine Laufzeitdifferenz Δt2, Δt3 gegenüber den Zeitpunkten tg2 und tg3 der Aussendung der Datentele­ gramme auf, wobei wegen der verschiedenen Abstände der ortsfesten Funk­ stationen von der mobilen Funkstation M Δt2 < Δt1 und Δt3 < Δt2 ist. Receives the mobile radio station M at a time t 1 ( Fig. 3) a data telegram D F1 of the first fixed radio station F1, the time difference between the times t 1 and t g1 corresponds to the running time difference Δt1 with which the data transmitted at the time t g1 telegram D F1 arrives at the mobile radio station M. The data telegram D F1 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 F2 from the fixed radio station F2 and then a data telegram D F3 from the fixed radio station F3, these data telegrams also each have a transit time difference Δt2, Δt3 compared to the times t g2 and t g3 of the transmission of the Data telegrams, due to the different distances between the fixed radio stations from the mobile radio station M Δt2 <Δt1 and Δt3 <Δt2.
Aus den Laufzeitdifferenzen Δt1, Δt2 und Δt3 und den bekannten Stand­ orten der ortsfesten Funkstationen F1, F2 und F3 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 transit time differences Δt1, Δt2 and Δt3 and the known status The computer C calculates the locations of the fixed radio stations F1, F2 and F3 the location of the mobile radio station M according to the rules of trigonometry The result of the calculation, that is, the current location of the mobile radio station M, the user of the mobile radio station is preferred indicated by means of a display. The condition for the stand Location determination that at least three data telegrams from three ver various fixed radio stations can be received.
