Title: Method and transmitter for transmitting data packets
Inventor: MOONEN BENNY
IPC: H04L12/801
Filed: 2004-02-09
Abstract: The invention relates to a method for transmitting a series of user data packets (DATA1, DATA2, DATA3) from a transmitter (PROXY) to a receiver (MS), optionally via one or more devices that route the data packets (DATA1, DATA2, DATA3), using a TCP protocol. At the start of the user data transmission, the transmitter (PROXY) transmits a first number of user data packets (DATA1) in the series of user data packets (DATA1, DATA2, DATA3) to the receiver (MS), whereby the user data packets are transmitted directly after one another in sequence during the transmission of several user data packets as the first number of user data packets. Once the first number of user data packets (DATA1) has been sent, the transmitter (PROXY) transmits no further user data packets to the receiver (MS) for a time period (ZS). At a later time (T), the transmitter (PROXY) transmits a second number of user data packets (DATA2, DATA3) in the series of user data packets (DATA1, DATA2, DATA3) to the receiver (MS) and the transmitter (PROXY) receives a confirmation of receipt (ACK) from the receiver (MS) that is transmitted upon receipt of the first number of user data packets (DATA1). According to the invention, the later time (T) is determined in such a way that it lies before the time (TA) of receipt of the confirmation (ACK) by the transmitter (PROXY) of the user data packets (DATA1, DATA2, DATA3). The invention also relates to a device (PROXY) comprising elements for carrying out the method on the transmitter side.
