Abstract

The radio transmission device for connecting servers to data terminals has a multiplexer for distributing data and involves using a technique for distribution the data using a radio distribution device and a multi-link protocol. An Independent claim is also included for a method of distributing data in a data distribution device.

Description

Mit der Erfindung wird folgendes Problem gelöst: Über einen Serverrechner mit nur einer Schnittstelle (beispielsweise einer RS232-Schnittstelle, einer USB-Schnittstelle oder einer V.24-Schnittstelle) sollen beliebig viele (n) Schnittstellen mit Datenterminals verbunden werden wobei n < 1 ist. Die Datenterminals können gleichzeitig aktivsein. The following problem is solved with the invention: About a Server computers with only one interface (for example an RS232 interface, a USB interface or one V.24 interface) should have any number of interfaces be connected to data terminals where n <1. The Data terminals can be active at the same time.

Bei den bisher bekannten Lösungen ist n = 1. Das heißt es ist nur eine Punkt zu Punkt Verbindung über eine Schnittstelle möglich. Für jedes Datenterminal, welches mit dem Server verbunden werden soll, muß der Serverrechner eine eigene Schnittstelle vorsehen.In the previously known solutions, n = 1. That is, it is only a point-to-point connection via an interface possible. For each data terminal connected to the server to be connected, the server computer must have its own Provide an interface.

Die Erfindung betrifft ein Protokoll (Multi Link Protokoll) welches es erlaubt sämtliche Signale der n Schnittstellen über eine Schnittstelle abzubilden.The invention relates to a protocol (multi-link protocol) which allows all signals of the n interfaces map via an interface.

Das Zusammenschalten der n Schnittstellen erfolgt über einen Konzentrator. Der Konzentrator wird über eine Schnittstelle mit dem Serverrechner verbunden. Serverrechner und Konzentrator kommunizieren über das Multi Link Protokoll. Das Multi Link Protokoll setzt die Schnittstellensignale der n Schnittstellen in n virtuelle Schnittstellen um. Das Protokoll ist Paketorientiert, so daß die n Schnittstellen gleichzeitig betrieben werden können.The n interfaces are interconnected via a Concentrator. The concentrator is through an interface connected to the server computer. Server computer and Concentrators communicate using the Multi Link protocol. The Multi Link protocol sets the interface signals of the n Interfaces into n virtual interfaces. The Protocol is packet-oriented so that the n interfaces can be operated simultaneously.

Nachfolgend soll die Erfindung anhand eines Ausführungsbeispiels erläutert werden; dabei wird auf eine Fig. 1 Bezug genommen.The invention will be explained below using an exemplary embodiment; reference is made to FIG. 1.

Verfahren zur Realisierung eines Daten HUBs über DECT "DECT DATEN HUB"Method for realizing a data hub via DECT "DECT DATA HUB"

  • - Der "DECT Daten HUB" ermöglicht Punkt zu Mehrpunkt Verbindungen im Client Server Betrieb über DECT. Im DECT Standard selber sind für den Uplink nur Punkt zu Punkt Verbindungen vorgesehen- The "DECT data HUB" enables point to multipoint Connections in client server mode via DECT. In the DECT The standard itself is only point to point for the uplink Connections provided
  • - Der "DECT Daten HUB" verbindet eine Anzahl von n Clients über DECT mit einem Server- The "DECT data hub" connects a number of n clients via DECT with a server
  • - Der "DECT Daten HUB" beinhaltet einen Multiplexer im Server, der m aus n Verbindungen auf eine physikalische Schnittstelle abbildet. Dadurch ist nur eine physikalische Schnittstelle im Server erforderlich. Die Datenrate dieser Schnittstelle kann ein vielfaches Datenrate eines DECT Kanals betragen, so daß ein echter Parallelbetrieb der m DECT Verbindungen möglich ist.- The "DECT data hub" contains a multiplexer in the Server that m out of n connections on a physical Maps the interface. This is just a physical one Interface in the server required. The data rate of this Interface can have a multiple data rate of a DECT Channel amount, so that a real parallel operation of the m DECT connections are possible.
  • - Jedem aktiven Client wird ein fester DECT Kanal zugeordnet. Dadurch ist eine gegenseitige Beeinflussung der Clients ausgeschlossen: Bei Ausfall eines Clients bleiben dies anderen erreichbar- Every active client has a fixed DECT channel assigned. This is a mutual influence of clients excluded: If one client fails remain accessible to others
  • - Der Datendienst bildet die anfallenden Datenpakete auf leitungsvermittelte DECT Verbindung entsprechend dem DECT- Standard ab. Die DECT-Verbindung wird nicht für jedes Paket auf- und abgebaut. Hierdurch entfällt die Zeit für den Auf- und Abbau und die Antwortzeiten bleiben kurz- The data service creates the data packets circuit-switched DECT connection according to the DECT Standard from. The DECT connection is not for everyone Package assembled and disassembled. This eliminates the time for assembly and dismantling and response times remain short
  • - Die DECT Verbindungen werden nach einer vorgegebenen Zeit ohne Daten (Client ist passiv) abgebaut. Durch den niedrigeren Stromverbrauch des Clients ohne DECT- Verbindung erhöht sich die Standbyzeit.- The DECT connections are terminated after a specified time without data (client is passive) dismantled. By the lower power consumption of the client without DECT Connection increases the standby time.
  • - Bei einer vorgegebenen Anzahl m von DECT Kanälen bildet der Datendienst die n Clients auf die m DECT Kanäle ab wobei n = m. Die Anzahl m wird begrenzt durch die verfügbaren DECT Ressourcen. Die Anzahl n kann größer als m werden, weil die DECT-Verbindung beim Übergang des Clients vom aktiven in den passiven Zustand abgebaut wird.- Forms DECT channels at a specified number m the data service transfers the n clients to the m DECT channels where n = m. The number m is limited by the available DECT resources. The number n can be greater than m because the DECT connection at the transition of the Clients from active to passive state.
