Abstract:
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, the method comprising the steps of: defining a transmit data packet number, for the convergence protocol packets to be sent, by a counter in a transmitter; transferring the convergence protocol packets to be sent to the link layer for transmission; defining a receive data packet number, for received convergence protocol packets, by a counter in a receiver; acknowledging the received convergence protocol packets; adding the transmit data packet number defined by the transmitter's counter to the convergence protocol packet to be sent in response to performance of a predetermined process of the telecommunications system; and updating the value of the receiver's counter to correspond to said transmit data packet number.
