System and method for improving the transmission behavior of a TCP / IP protocol data transmission over a unidirectional radio link

摘要

A system and method for data transmission comprise at least one wired connection (4) between a server (1), operating on the TCP/IP protocol and an exchange (3) and at least one mono-directional radio connection between the exchange (3) and a client (2), operating with the TCP/IP protocol. On a transmission loss of a data packet in a mono-directional radio connection (5), a temporary additional connection (24), between the client (2) and the exchange (3), is established on the IP level, for a repeated transmission of the lost data packet. Transmission losses can be directly recognised by means of the above system and a repeat transmission initiated. The system generates no additional run-time for data buffering with an error-free transmission.
