    • In a digital data transmission system using sliding-window flow control with an adjustable window size on a non-transparent data connection whose nominal data transmission rate may vary during the connection, a receiving party delays the transmission of a retransmission request for a missing frame for the duration of a delay, so that the receiving party may ensure that the missing frame has not been moved to be sent later in the same group or in next groups. If the missing frame is received later in the same group or in the next groups within said delay, no retransmission request is sent. If the missing frame is not received by the end of the delay, a retransmission request is sent. This eliminates unnecessary retransmissions due to the wrong frame order, and resulting loading or congestion. This results in a higher throughput on the data connection. If grouping is not being used, retransmission is not delayed unless a delay is needed for another reason.

    • A digital mobile communication system has a high-speed non-transparent data connection between a transmitting and a receiving party (MS, TAF). For the data connection, parallel subchannels (ch1-chn), corresponding in number to the nominal data transfer rate, have been allocated on the radio interface. A radio link protocol (RLP) is responsible for transmitting data over the radio interface, and for acknowledging correct data frames and for retransmitting defective data frames. A transmission buffer (63) buffers the data frames to be transmitted and stores the data frames transmitted until it receives an acknowledgement of successful reception. In order to reduce interference and power consumption, user data is transmitted by using as many of the allocated subchannels as required by the actual user data rate at any one time. On the other allocated subchannels, transmission is interrupted or discontinuous transmission is activated.

    • In a communications system, the subscriber data in a home network of a subscriber is provided with a subscriber ciphering profile, which indicates whether an unciphered call, session or data packet is to be rejected, accepted or handled in some other manner. A serving network checks the subscriber ciphering profile in one or more of the following cases: 1) for each setup of an unciphered call or connection, 2) for each unciphered packet switched data transmission session, or 3) for each packet data transmission originating from subscriber equipment, and rejects or accepts the unciphered call, connection, session, or data packet, respectively, according to the subscriber ciphering profile. As a result, unciphered calls, sessions, or packet data transmissions will be reliably rejected.
