Patent ID: 8341272

Claim:
A method for the improvement of a TCP data transmission process in a mobile communications network, wherein after the establishment of a TCP connection between a client and a server a data packet is transmitted from the server to the client, wherein the receipt of the data packet from the server is confirmed by the client by the transmission of a confirmation message assigned to the received data packet (ACK message), the method comprising: at the time that the ACK message is transmitted by the client, starting a timer with a default time T 1 ; the client repeatedly transmitting to the server the same ACK message in the case where no further data packet has been received from the server after the expiration of the time T 1 ; and the client storing each transmitted ACK message at least until an ACK message must be sent again; whereupon exceeding of a default threshold value no further ACK message of the same content will be sent to the server; the timer not being activated during the establishment and clearing of a connection between the client and server.
