Abstract

The invention relates to an information platform for emergency services and intervention forces. The invention is characterised in that: the offered information is managed by means of a network according to the Internet protocol; the offered information is transmitted according to the DVB standard (DVB); in addition to video and/or audio data (K1, K2, K3), data associated with an application is also transmitted according to the MHP standard; the information offered is controlled by means of digital trunked radio (TETRA); and a control application that functions as a central control element is provided on a network server according to the Internet protocol. The inventive information platform permits the bandwidth restrictions of conventional communications solutions for emergency services and intervention forces to be overcome.

Description

Informationsplattform für EinsatzkräfteInformation platform for emergency services
Die Erfindung betrifft eine Informationsplattform für Einsatzkräfte.The invention relates to an information platform for emergency services.
Der effiziente und zielgerichtete Einsatz von Ordnungs- und Hilfskräften wie Polizei, Feuerwehr, Rettung oder militärischen Kräften erfordert die umfassende und zeitlich aktuelle Information aller Beteiligten über wesentliche Einsatzbedingungen und Einsatzvoraussetzungen.The efficient and goal-oriented use of law enforcement and auxiliary personnel such as the police, fire brigade, rescue or military forces requires the comprehensive and up-to-date information of all concerned about essential conditions of operation and operational conditions.
Dazu ist aus dem Stand der Technik beispielsweise das Bündelfunksystem gemäß dem TETRA(terrestrial trunked radio) - Standard bekannt, welcher sich wegen seiner besonderen Funktionen besonders für Behörden und Organisationen mit Sicherheitsaufgaben eignet.For this purpose, for example, the trunked radio system according to the TETRA (terrestrial trunked radio) standard is known from the prior art, which is particularly suitable for authorities and organizations with security tasks because of its special functions.
Das volldigitale System TETRA zeichnet sich gegenüber herkömmlichen Mobilfunkstandards wie z.B. GSM durch hohe Übertragungsqualität und bessere Frequenzökonomie aus. Neben der Übertragung von Sprache und Daten können mit der Spezialfunktion "Packet Data Optimized" auch Datenmengen paketorientiert übertragen werden.The fully digital TETRA system distinguishes itself from conventional mobile radio standards such as e.g. GSM by high transmission quality and better frequency economy. In addition to the transmission of voice and data, data sets can also be transmitted in a packet-oriented manner with the special function "Packet Data Optimized".
TETRA ist als Zeitmultiplex-System mit vier unabhängigen Kommunikationskanälen pro Träger definiert. Der Abstand zwischen den einzelnen Trägern beträgt 25 kHz. Gegenüber analogem Bündelfunk bedeutet das eine bessere Frequenznutzung bei gleichzeitig besserer Sprachqualität. TETRA-Systeme bieten gegenüber GSM-Netzen, die bei 200 kHz Kanalabstand acht Kommunikationskanäle bereitstellen, die vierfache Frequenznutzung.TETRA is defined as a time-division multiplex system with four independent communication channels per carrier. The distance between the individual carriers is 25 kHz. Compared with analogue trunked radio, this means better frequency usage and better voice quality. TETRA systems offer quadruple frequency usage over GSM networks providing eight channels of communication at 200 kHz channel spacing.
Die Übertragungsrate bei TETRA beträgt immer 36 kBit/s pro Funkkanal. Neben den zu übertragenden Daten werden zusätzliche Steuersignale sowie Codes zur Sicherung der Funkstrecke übertragen. Die Nutzbitrate proThe transmission rate with TETRA is always 36 kBit / s per radio channel. In addition to the data to be transferred transmit additional control signals and codes to secure the radio link. The user bitrate per
Kommunikationskanal beträgt 7,2 kBit/s. Sprache wird in einem speziellen TETRA-CODEC umgesetzt.Communication channel is 7.2 kbps. Language is implemented in a special TETRA CODEC.
Für Gegensprechen (Duplex-Betrieb) wird bei TETRA das Time Division Duplex Verfahren eingesetzt. Dabei wird die Sprache zeitlich so komprimiert, daß eine kontinuierliche Zweiwegkommunikation über zwei versetzte Zeitschlitze möglich ist.For intercom (duplex mode) TETRA uses the Time Division Duplex method. The speech is compressed in time so that a continuous two-way communication over two staggered time slots is possible.
TETRA verfügt auch über einen sog. Direktmodus, bei dem zwei oder mehrere Funkgeräte unabhängig vom Netz miteinander kommunizieren können. Auch kann ein einzelnes Funkgerät als mobile Relaisstation für andere Geräte eingesetzt werden. So kann ein Gerät im Fahrzeug als Relais die Funkversorgung der Handfunkgeräte auf einem Areal sicherstellen.TETRA also has a so-called direct mode, in which two or more radios can communicate independently of each other. Also, a single radio can be used as a mobile relay station for other devices. Thus, a device in the vehicle as a relay can ensure the radio coverage of the handheld radios on an areal.
Zur Datenübertragung im TETRA-Netz können ein bis vier Zeitschlitze zusammengefasst werden. Damit istFor data transmission in the TETRA network, one to four timeslots can be combined. This is
Datenübertragung bis zu 28,8 kBit/s möglich, was allerdings für breitbandige Dienste wie beispielsweise die Echtzeitübertragung von Filmen nicht ausreicht.Data transfer up to 28.8 kBit / s possible, but this is not sufficient for broadband services such as the real-time transmission of films.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Lösung anzugeben, mit der auch anspruchsvolle breitbandige Inforamtionsdienste angeboten werden können.The invention is therefore based on the object of specifying a solution with which demanding broadband information services can be offered.
Diese Aufgabe wird erfindungsgemäß gelöst mit einer Informationsplattform für Einsatzkräfte bei der dieThis object is achieved with an information platform for emergency services in the
Verwaltung des Informationsangebotes mittels Netz nach dem Internetprotokoll erfolgt, bei der die Übertragung des Informationsangebotes nach dem DVB-Standard erfolgt, bei der neben Video- und/oder Audiodaten auch Daten zu einer Anwendung gemäß dem MHP-Standard übertragen werden, bei der die Steuerung des Informationsangebotes mittels digitalem Bündelfunk erfolgt und bei dem als zentrales Steuerelement eine Steueranwendung auf einem Server eines Netzes nach dem Internet Protokoll vorgesehen ist.Management of the information offer by means of network according to the Internet protocol is carried out, in which the transmission of the information offered in accordance with the DVB standard, in which in addition to video and / or audio data and data to an application according to the MHP standard are transmitted, in which the control of Information offered by means of digital trunked radio and in which as a central control a control application is provided on a server of a network according to the Internet Protocol.

Beschränkungen herkömmlicher Kommunikationsnetze überwunden. Damit ist es ermöglicht, auf Filmaufnahmen, Datenbanken oder andere Informationen mit hohen Datenmengen zuzugreifen.Overcoming limitations of traditional communication networks. This makes it possible to access film recordings, databases or other information with a high volume of data.
Die Steuerung des Informationsangebotes erfolgt vorteilhafterweise mittels digitalem Bündelfunk gemäß dem TETRA Standard, alternativ sind aber auch andere professionelle Bündelfunksysteme wie beispielsweise TETRAPOL denkbar.The information service is advantageously controlled by means of digital trunked radio according to the TETRA standard, but other professional trunked radio systems such as TETRAPOL are also conceivable.
Zur Darstellung der Informationsplattform auf den Bildschirmen der Endgeräte ist der von der europäischen Industrie entwickelte Multimedia Home Platform (MHP) - Standard vorgesehen. Dieser liefert eine gemeinsame interaktive Basis für (Fernseh-) Programmanbieter, Endgerätehersteller und Netzbetreibern.To present the information platform on the terminal screens, the Multimedia Home Platform (MHP) standard developed by the European industry is foreseen. This provides a common interactive basis for (television) program providers, terminal manufacturers and network operators.
