Problems solved by technology

[0004] In case the transmitter mistakenly interprets a negative acknowledgment message from the receiver as a positive acknowledgment message, and continues to transmit a new packet, there is information about a packet that was erroneously received from the receiver for which a negative acknowledgment message was sent was lost

Embodiment Construction

[0023] Figure 1 shows components of a mobile radio communication system, such as a digital cellular telecommunication system, according to an embodiment of the invention. Specifically, Figure 1 shows two types of networks, namely a part of a fixed network (such as a public switched telephone network PSTN, such as the National Telephone Network, Integrated Services Digital Network ISDN or Packet Switched Public Data Network PSPDN) and a public land mobile network PLMN (eg UMTS mobile radio communication system). To link these networks, a Gateway GPRS Support Node GGSN is provided for determining the specific location of a mobile station MS in the digital cellular telecommunication system and for routing incoming calls towards this mobile station MS.

[0024] To this end, the GGSN is connected to a functional unit called the Home Location Register HLR, in which two types of information are stored, subscriber information and mobile information, to enable incoming calls to be rout...

Abstract

Due to NACK-to-ACK misinterpretations in base stations, packets are lost, and there may be gaps in a re-ordering buffer of a base station. According to the present invention, when the receiver decodes - possibly after some retransmissions - a first data packet without an error, which first data packet is sent along with an indicator indicating that the first data packet is a new data packet, after the receiver has sent a negative confirmation message (NACK) with respect to a second data packet, the receiver sends a Revert (REV) message to the transmitter. The REV message informs the base station that the first data packet was decoded error-free, and that the second data packet is still missing on the receiving side so that the base station may re-send this second data packet.

Description

technical field [0001] The invention relates to the field of packet switching data transmission, especially the packet switching data transmission in radio mobile communication systems. More specifically, the present invention relates to a method for transmitting data packets from a transmitter to a receiver, a system for transmitting data packets from a transmitter to a receiver, a base station for a mobile radio communication system, a system for For a mobile subscriber station of a mobile radio communication system, a computer program for controlling the transmission of data packets from a transmitter to a receiver of a mobile radio communication system. Background technique [0002] For example, from "Tdoc 12A010024, Signaling and timing constellations for HS-DSCH (Tdoc 12A010024, signaling and timing constellations for HS-DSCH)" (Source: Lucent Technologies, 3GPP TSG RAN WG1&WG2 Meeting on HSDPA, SophiaAntipolis, 2001 4 A method and system for transmitting a data packe...
