Data packet numbering in packet-switched data transmission
First Claim
1. A method for transmission of data packets in a packet-switched telecommunications system, the telecommunications protocol of which comprises a convergence protocol layer for converting user data packets into convergence protocol packets, and a link layer for transmitting convergence protocol packets as data units and for acknowledging the transmission, comprising defining a data packet number for the convergence protocol packets to be sent by a counter, transmitting the convergence protocol packets to be sent to the link layer for transmission, defining a data packet number for received convergence protocol packets by the counter, and acknowledging the received convergence protocol packets.

Abstract
A method of numbering data packets in a packet-switched telecommunications system which utilizes acknowledged transmission and the telecommunications protocol of which comprises a convergence protocol layer for converting user data packets into convergence protocol packets, and a link layer for transmitting convergence protocol packets as data units and for acknowledging the transmission. A data packet number is defined for the convergence protocol packets to be sent by a counter and the convergence protocol packets to be sent are transmitted to the link layer for transmission without the data packet number. A data packet number is also defined for received convergence protocol packets by means of the counter and an acknowledgement of received convergence protocol packets is transmitted to the transmitter.

10. A packet-switched telecommunications system which comprises a terminal and a fixed network, which comprises a network element supporting packet-switched data transmission, data packets being arranged to be sent between the terminal and the network element in the telecommunications system and the telecommunications protocol of the telecommunications system comprising a convergence protocol layer for converting user data packets into convergence protocol packets, and a link layer for transmitting convergence protocol packets as data units and for acknowledging the transmission, wherein in the transmission of data packets between the terminal and the network element
a data packet number is arranged to be defined for the convergence protocol packets to be sent by means of a counter, the convergence protocol packets to sent are arranged to be transmitted to the link layer for transmission, the data packet number is arranged to be defined for received convergence protocol packets by the counter, and received convergence protocol packets are arranged to be acknowledged.
