Abstract

The invention relates to a method for transmitting a series of user data packets from a transmitter to a receiver using a TCP protocol. A first number of user data packets in the series is transmitted to the receiver in sequence during the transmission of several user data packets. Subsequently, the transmitter transmits a second number of user data packets to the receiver, and the transmitter receives a confirmation of receipt from the receiver upon receipt of the first number of user data packets. The timing of the subsequent transmission is determined so that transmission occurs before receipt of the confirmation by the transmitter of the user data packets. The invention also relates to a device comprising elements for carrying out the method on the transmitter side.

Claims

1. A method for transmitting a series of user data packets from a transmitter to a receiver using a TCP protocol, comprising:

transmitting, at the start of the user data transmission, a first number of user data packets from the series of user data packets to the receiver;

transmitting, during transmission of a plurality of user data packets, the user data packets directly one after the other as the first number of user data packets, and not transmitting user data packets to the receiver for a time period after transmitting the first number of user data packets;

transmitting a second number of user data packets from the series of user data packets to the receiver at a later time; and

receiving a confirmation of receipt transmitted on receipt of the first number of user data packets from the receiver, wherein

the later time is defined such that it is before a time of receipt of the confirmation of receipt by the transmitter of the user data packets.

2. The method according to claim 1, wherein the later time is defined such that the receiver receives the second number of user data packets after transmitting the confirmation of receipt.

3. The method according to claim 1, wherein the time period is a function of a time difference between transmission of a data packet by the transmitter and receipt of the data packet by the receiver.

4. The method according to claim 1, wherein the user data packets are transmitted by the transmitter to the receiver at least to some degree by radio.

5. The method according to claim 1, wherein the user data packets are data from the internet.

6. The method according to claim 1, wherein

the receiver is part of a mobile radio communication system, and

the transmitter is a device connected both to the mobile radio communication system and another network using a TCP protocol.

7. The method according to claim 1, wherein the second number of user data packets exceeds the first number of user data packets.

8. A device for transmitting a series of user data packets to a receiver comprising:

a first unit for using a TCP protocol to transmit user data packets;

a second unit for transmitting a first number of user data packets from the series of user data packets to the receiver, during transmission of a plurality of user data packets directly one after the other as the first number of user data packets; and

a third unit for transmitting a second number of user data packets from the series of user data packets to the receiver at a later time after a time period after transmitting the first number of user data packets, wherein

the device has a fourth unit for defining the later time, such that the later time is before a time of receipt of a confirmation of receipt transmitted by the receiver on receipt of the first number of user data packets in the device.

9. The device according to claim 8, wherein the time period is a function of a time between transmission of a data packet by the device and receipt of said data packet by the receiver.

10. The device according to claim 8, wherein the device is connected to a mobile radio communication system such that the user data packets can be transmitted via the mobile radio communication system to the receiver.
