Abstract
Description
Es sind Verfahren zur Erzeugung von einheitlichen Verkehrsmeldungen bekannt. Dazu gehören beispielsweise das ALERT C-Protokoll, nach dem die Meldungen des Traffic Message Channel (TMC) generiert werden. Dieses Protokoll ist auf die Minimierung des Nachrichtenumfanges zur Übertragung über stark bandbreitenlimitierte FM-Rundfunkkanäle optimiert.Methods are known for generating uniform traffic reports. This includes for example, the ALERT C protocol, after which the messages of the Traffic Message Channel (TMC) to be generated. This protocol is aimed at minimizing the message size for transmission optimized over bandwidth-limited FM broadcast channels.
Weiterhin existiert das Road Traffic Message (RTM) Verfahren, das weitaus detailliertere Nachrichten als TMC zuläßt. Durch diesen Detaillierungsgrad werden jedoch die Datenmengen deutlich erhöht, so daß hier vornehmlich ein Einsatz über hochdatenratige Kanäle wie DAB, GSM oder UMTS vorgesehen ist.There is also the Road Traffic Message (RTM) process, the much more detailed news as TMC permits. However, this level of detail significantly increases the amount of data, so that here primarily a use over high data rate channels such as DAB, GSM or UMTS provided is.
Derzeit steht jedoch kein standardisiertes Verfahren zur Verfügung, das eine Verkehrsmeldung in einen komprimierten Anteil zur optimierten Datenübertragung über limierte Kanäle und in einen optionalen ergänzenden Anteil über erweiterte Kanäle zuläßt. Dabei soll über die verpflichtende Nachricht auf die optionale Nachricht und deren Auffindbarkeit hingewiesen werden.At present, however, there is no standardized method that provides a traffic announcement in a compressed portion for optimized data transmission over limed channels and into one optional supplementary share via extended channels. This is about the mandatory Message to the optional message and its findability.
Diesbezüglich ist lediglich ein unter xTMC bekanntes Verfahren bei Bosch unter der Patentnummer DE19905893 angemeldet worden. Dieses beruht im wesentlichen darauf, daß vor den bekannten TMC-Nachrichten ein zusätzlicher Header vorangestellt wird, der auf einen zusätzlichen folgenden, nicht unbedingt ALERT C konformen Anteil hinweist. Dieses Verfahren ist aber insbesondere dann von Nachteil, wenn über einen Kanal nur TMC spezifische Informationen gesendet werden dürfen. In diesem Fall ist auch kein zusätzlicher xTMC-Header erlaubt, der weitere Nachrichten ankündigt. In this respect, only a method known under xTMC is under the patent number of Bosch DE19905893 has been filed. This is based essentially on the fact that before the known TMC messages is preceded by an additional header, which is followed by an additional not necessarily ALERT C compliant proportion indicates. But this method is especially of Disadvantage, if only TMC-specific information can be sent over one channel. In In this case, no additional xTMC header is allowed, which announces further messages.
Das erfindungsgemäße Verfahren erweitert die vorhandenen TMC-Meldungen nach dem ALERT C-Protokoll ohne eine Änderung des Nachrichtenformates so, daß beliebige Zusatzinformationen zugeordnet werden können.The inventive method extends the existing TMC messages according to the ALERT C protocol without changing the message format so that any additional information can be assigned.
Eine Verkehrsmeldung wird in eine Basisnachricht und eine optionale Ergänzungsnachricht aufgeteilt.
Die Basisnachricht entspricht dabei vollständig den ALERT-C Spezifikationen, während die
Ergänzungsnachricht zunächst nicht näher spezifizierte Inhalte umfassen kann. Um die Existenz einer
erweiterten Nachricht zu kennzeichnen, werden in der dazugehörigen TMC-Basisnachricht bisher
vorhandene, aber nicht belegte Gruppen verwendet. Diese werden im ALERT C Protokoll durch
sogenannte LABEL gekennzeichnet. Eine solche Nachricht kann bei Nutzung des Label 12 16 Bit
Nutzdaten umfassen. Bei Nutzung des Label 15 ist noch nicht festgelegt, wie viele Bits die Nutzdaten
umfassen dürfen. Diese Nutzdaten werden nach erfindungsgemäßem Verfahren um weitere 4 Bit
reduziert, wodurch ein sogenanntes Sublabel mit weiteren 16 Zuständen eingeführt wird. Durch dieses
Sublabel ist die Kennzeichnung von Subdiensten zu Label 12 möglich. Die verbleibenden 12 Bit
werden als echte Nutzdaten verwendet und ermöglichen beispielsweise eine eindeutige Zuordnung
einer optionalen Zusatznachricht zu einer verpflichtenden Basisnachricht.A traffic message is divided into a base message and an optional supplementary message.
The basic message corresponds fully to the ALERT-C specifications, while the
Supplemental message may initially include unspecified content. To the existence of a
extended message in the TMC base message so far

In einer vorteilhaften Weiterentwicklung lassen sich in den sogenannten GRUPPEN des Radio Data Service (RDS)-Protokolls weitere Informationen unterbringen. Beispielsweise werden in der Gruppe 3A Anwendungsnummern bzw. Application IDs vergeben. Wenn eine solche Applicationsnummer dem neuen Dienst zugeordnet wird, ist es möglich, auch die dort zur Verfügung stehenden Nutzdaten zu verwenden.In an advantageous development can be in the so-called GROUPS of Radio Data Service (RDS) logs for more information. For example, in group 3A Assign application numbers or application IDs. If such a applications number the new service is assigned, it is also possible to use the user data available there use.
Der Vorteil des gesamten erfindungsgemäßen Verfahrens besteht darin, daß auf einem bewährten datenoptimierten Protokoll zur Verkehrsnachrichtenübertragung aufgesetzt wird. Dieses Protokoll wird nicht modifiziert, sondern nur erweitert, so daß weiterhin eine vollständige Abwärtskompatibilität besteht. Lediglich der erweiterte Meldungsanteil läßt sich nicht durch alte Endgeräte auswerten. The advantage of the entire method according to the invention is that on a proven Data-optimized protocol for traffic news transmission is set up. This protocol will not modified, but only extended, leaving full backward compatibility consists. Only the extended message share can not be evaluated by old terminals.
Weiterhin läßt sich dieses Verfahren auf jedem Kanal anwenden auf dem das ALERT C-Protokoll eingesetzt werden kann.Furthermore, this method can be applied to any channel using the ALERT C protocol can be used.
Das erfindungsgemäße Verfahren setzt zunächst voraus, daß Verkehrsmeldungen nach dem ALERT C-Protokoll erzeugt werden, die aus einer Basis- und einer Ergänzungsmeldung bestehen. Die Basismeldung entspricht dem bekannten TMC-Pormät und wird beispielsweise über FM-RDS-Dienste oder DAB-FIC parallel zum Rundfunkprogramm ausgestrahlt. Diese Meldungen können somit neben dem Audio-Radiobetrieb empfangen werden. Dies ist insbesondere dadurch möglich, daß es sich bei den TMC-Meldungen um ein hochoptimiertes Datenformat handelt, indem Nachrichten in weniger als 100 Bit untergebracht werden können. Nach dem derzeitigen Stand des ALERT C-Protokolls erweist sich jedoch die geringe Ortsauflösung der Verkehrsnachrichten, die an sogenannte Ortstabellen gebunden sind, als nachteilhaft. Wenn alle verkehrsrelevanten Straßenabfahrten in derartige Ortstabellen aufgenommen werden sollen, ergibt sich daraus ein Verwaltungsaufwand undThe inventive method first assumes that traffic reports after the ALERT C protocol, consisting of a base message and a supplementary message. The Basic message corresponds to the known TMC format and is used, for example, via FM RDS services or DAB-FIC broadcast in parallel to the broadcast program. These messages can thus be next to be received in the audio-radio operation. This is particularly possible because it is at The TMC messages are a highly optimized data format by sending messages in less than 100 bits can be accommodated. According to the current state of the ALERT C protocol proves However, the low spatial resolution of the traffic news, the so-called place tables are bound as disadvantageous. If all traffic-related road departures in such This results in an administrative burden and
Tabellengrößen, die für handelsübliche Endgeräte nur schwer handhabbar sind.Table sizes that are difficult to handle for commercial end devices.
Als vorteilhafte Weiterentwicklung lassen sich durch das erfindungsgemäße Verfahren über Ergänzungsmeldungen Zusatzinformationen integrieren, die beispielsweise über geeignete Georeferenzierungsverfahren eine bessere Ortsauflösung zur Basismeldung hinzufügt.As an advantageous development can be by the inventive method on Supplementary messages Integrate additional information, for example, via appropriate Georeferencing method adds a better spatial resolution to the base message.
Die Gesamtmeldung setzt sich dann folgendermaßen zusammen (Abbildung 1):
- TMC-Basismeldung in RDS-
Gruppe 8. - Kennzeichnung einer Zusatzmeldung unter einem zumindest teilweise ungenutzten Label (z. B. 12
oder 15) in der RDS-
Gruppe 8. - Die Nutzdaten der Meldung unter
Gruppe 8 werden um 4 Bit für ein Sublabel reduziert. Das Sublabel wird dann beispielsweise auf (0001dual) gesetzt, wodurch der erweiterte TMC-Dienst gekennzeichnet wird. - In den verbleibenden Nutzdaten (12 Bit) wird eine eindeutige Nachrichten-ID der Meldung vergeben, nach der auf demjenigen Kanal gesucht werden soll, auf dem die erweiterten TMC-Meldungen ausgestrahlt werden.
- TMC Basic Message in RDS
Group 8. - Identification of an additional message under an at least partially unused label (
eg 12 or 15) in theRDS group 8. - The payload of the message under
group 8 is reduced by 4 bits for a sublabel. The sub-label is then set to (0001dual), for example, indicating the enhanced TMC service. - The remaining user data (12 bits) is assigned a unique message ID of the message to be searched for on the channel on which the extended TMC messages are broadcast.
Das empfangende Endgerät, das den erweiterten Verkehrsnachrichtendienst verarbeiten kann, schaltet nun auf einen bekannten Zusatzkanal für erweiterte TMC-Meldungen und wartet dort auf eine Nachricht, die dieser Nachrichten-ID entspricht. Bei DAB kann der Zusatzkanal im gleichen Ensemble auch parallel dekodiert werden. Dies bietet den Vorteil einer schnelleren Dekodierung.The receiving terminal that can handle the enhanced traffic information service Now switches to a known additional channel for extended TMC messages and waits there for one Message that matches this message ID. With DAB, the additional channel can be in the same ensemble also be decoded in parallel. This offers the advantage of faster decoding.
Dadurch, daß sich durch die verbleibenden 12-Bit Nutzdaten nur 4096 Nachrichten-lDs abdecken lassen, werden in einer vorteilhaften Weiterentwicklung weitere Erkennungsmerkmale in die Zusatznachrichten eingebunden. Beispiele dafür sind
- die Einprägung von eindeutiger Uhrzeit und Datum in TMC- und Zusatzmeldung oder auch
- die Wiederholung der TMC-Basismeldung in der Zusatznachricht (Abbildung 2).
- the imprint of clear time and date in TMC and additional message or also
- the repetition of the basic TMC message in the supplemental message (Figure 2).
Bisher wird davon ausgegangen, daß der Empfänger den Kanal kennt, auf dem die Zusatzmeldung nach dem Erhalt einer Basismeldung übertragen wird. In einer vorteilhaften Weiterentwicklung läßt sich diese Information über weitere in dem entsprechenden Übertragungsmedium spezifizierte Kanäle übertragen. Ein Beispiel dafür ist die 3A-Gruppe des RDS-Protokolls, in der sich eine Application-lD (AID) angeben läßt. Wenn für den erweiterten TMC-Dienst eine eigene AID vergeben wird, kann ein entsprechender Empfänger im Zusammenhang mit der als erweitert gekennzeichneten TMC-Nachricht eine 3A-Meldung des RDS-Protokolls ausgewertet werden. Diese Meldung enthält dann die notwendigen Zusatzinformationen, die zur eindeutigen Beschreibung des Kanals notwendig ist, auf der die Zusatzmeldung zu erwarten ist (Abbildung 3). Bei DAB wird in diesem Falle eine Service-Komponente (service component) referenziert.So far, it is assumed that the receiver knows the channel on which the additional message after receiving a basic message. In an advantageous development leaves This information about other specified in the appropriate transmission medium channels transfer. An example of this is the 3A group of the RDS protocol, in which an application ID (AID). If a separate AID is assigned for the extended TMC service, a corresponding receiver in connection with the marked as extended TMC message a 3A message of the RDS protocol are evaluated. This message then contains the necessary additional information, which is necessary for a clear description of the channel, on the the additional message is expected (Figure 3). DAB becomes a service component in this case (service component) referenced.
Als weitere Möglichkeit kann bei DAB der TMC-Basisdienst und die erweiterte TMC-Funktionalität in einem DAB Service zusammengefasst werden. Der besondere Vorteil liegt hier in der einfachen Zuordnung von TMC-Basismeldungen und Zusatznachrichten, da keine 3A Gruppen ausgewertet werden müssen um den Kanal für die Zusatznachrichten zu finden (Abbildung 4). Der DAB TMC-Basisdienst und der DAB TMC-Zusatzdienst sind durch die DAB Signalisierung als in einem Service befindlich implizit miteinander verknüpft.Another option for DAB is the TMC base service and the enhanced TMC functionality in be summarized a DAB service. The special advantage here lies in the simple Assignment of TMC basic messages and additional messages, as no 3A groups evaluated to find the channel for the additional messages (Figure 4). The DAB TMC basic service and the DAB TMC additional service are through the DAB signaling as in a service implicitly linked together.
Die Schuhstraße in Hildesheim soll am 28.11.2001 wegen einer Veranstaltung von 12:00-16:00 Uhr gesperrt werden. Dazu wird folgende TMC-Meldung generiert, die im folgenden Basisnachricht genannt wird:The Schuhstraße in Hildesheim will be on 28.11.2001 because of an event from 12: 00-16: 00 clock be locked. The following TMC message is generated in the following basic message is called:
Aufgrund der reduzierten Ortsauflösung läßt sich durch das ALERT C-Protokoll nur die Location ...
zuordnen. Durch ein geeignetes Georeferenzierungsverfahren wird die Meldung exakt referenziert, und
die Zusatzdaten werden in einer Ergänzungsnachricht der Basismeldung hinzugefügt.
Ein Fahrzeugführer empfängt die TMC-Basismeldung mit einem erfindungsgemäßen Endgerät und
kann folgende Meldung entschlüsseln:Due to the reduced spatial resolution, only the location ... can be assigned by the ALERT C protocol. By a suitable georeferencing method, the message is exactly referenced, and the additional data is added to the basic message in a supplemental message.
A vehicle driver receives the TMC basic message with a terminal according to the invention and can decrypt the following message:
Das Gerät erkennt anhand des Labels 12 und des Sublabels (0001 dual) in 4 Bit der 16 Bit Nutzdaten,
daß eine erweiterte TMC-Meldung vorliegt. In den übrigen Nutzdaten erkennt das Gerät weiterhin, daß
es sich um eine Nachricht mit der Kennung 647 handeln muß. Auf einem weiteren, bekannten Kanal
ruft das Endgerät nun die erforderlichen Zusatzinformationen ab. Das Endgerät schaltet nun auf einen
weiteren Kanal, der für den Empfang von TMC-Zusatzmeldungen bekannt ist. Dort wartet das Gerät
eine Meldung, die ein Ereignis am 28.11.2001 von 12:00-16:00 Uhr mit der Kennung 647 genauer
beschreibt. Bei DAB erfolgt ggf. eine parallele Dekodierung. Alternativ kann der Wartezustand des
Gerätes auch durch andere Ereignisse, wie beispielsweise der Ablauf eines Zeitgebers beendet
werden.
Wenn das Gerät über die vorteilhafte Ergänzung verfügt, muß der Kanal der Zusatzdaten nicht vorher
festgelegt werden. Stattdessen wurde die RDS AID 34 in der Gruppe 3A für den erweiterten TMC-Dienst
definiert Nach der vorliegenden Meldung wird nun in der RDS-Gruppe 3A die AID 34 erwartet,
in deren Nutzdaten der Kanal beschrieben wird, auf dem die Zusatzinformationen vorliegen werden.
Für DAB ist dies der Ensemble Identifier (Eld), Service ldentifier (Sld) und Service Component
Identifier within the Service (SCIDs) bzw. Service Component Identifier (SCld).
Falls bei DAB der TMC-Basisdienst und der erweiterte TMC-Dienst im gleichen Service übertragen
werden, wertet ein erfindungsgemäßer Empfänger die TMC-Basisnachrichten aus diesem DAB-Service
in Kombination mit den TMC-Zusatznachrichten aus diesem Service aus. Der DAB Service
besteht zum Beispiel aus einer primary audio Komponente, TMC-Basiskomponente und TMC-Zusatzkomponente.The device recognizes from the
If the device has the advantageous addition, the channel of the additional data need not be set beforehand. Instead, the RDS AID 34 has been defined in the group 3A for the extended TMC service. Following the present message, the AID 34 is now expected in the RDS group 3A, in whose user data the channel is described on which the additional information will be available. For DAB this is the Ensemble Identifier (Eld), Service Identifier (Sld) and Service Component Identifier within the Service (SCIDs) or Service Component Identifier (SCld).
In DAB, if the TMC base service and the enhanced TMC service are transmitted in the same service, a receiver of the invention evaluates the TMC base messages from that DAB service in combination with the TMC supplemental messages from that service. The DAB service consists, for example, of a primary audio component, basic TMC component and additional TMC component.
