Transmission method for packet oriented data network with mobile stations, using proxy working in layer above transport layer in one of repeaters for switching between stationary and mobile transmissions

The data transmission is performed between a fixed station (2) and a mobile station (9) arranged between two sub-networks (6,7). First a stationary transmission is set up between the fixed station (2) and a first repeater (4) arranged in a firsts sub-network (6) and also a mobile transmission between the first repeater (4) and a mobile station (9) within the first sub-network (6). During the data transmission the first repeater (4) is notified about the network change-over (14) from the mobile station (9) of the first sub-network (6) to the second sub-network (7). A further mobile transmission is set up over the second repeater (5) arranged in the second sub-network (7). A proxy working in a layer above a transport layer in one of two repeaters (4,5) is used for switching between the stationary and mobile transmissions. Independent claims are also included for a repeater, mobile router, mobile nodes, computer program for operating a repeater, computer program for operating mobile nodes, a computer program for operating a mobile router. Zum Betrieb eines mobilen Knotens (9) an einem festen Datennetz (1) wird vorgeschlagen, Zwischenstellen (4, 5) mit den Funktionen eines auf einer Ebene oberhalb der Transportebene arbeitenden Proxys zu versehen. Dadurch ist es möglich, auch Datenströme, die als Transportprotokoll nicht TCP verwenden, bei einem Netzwechsel (14) mit geringen Verzögerungszeiten zu übertragen.
