    • 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 telecommunications system and method for non-transparent data transmission includes a non-transparent data connection between a transmitting party and a receiving party, on which channel coding is employed. The transmission buffer buffers the data frames to be transmitted and stores the transmitted data frames until it receives an acknowledgement of successful reception. This is avoided by monitoring the quality of the non-transparent connection, and if the quality of the the connection drops to a specific threshold value, by changing the channel coding scheme of the connection for a more efficient one. Simultaneously, however, more channel capacity is allocated for the connection in according with the chosen channel coding scheme so that the original nominal user data rate can be maintained unchanged or nearly unchanged.

    • The invention relates to a handover method in a mobile communication system in which error correction of a radio signal can be arranged with different protection levels. The method comprises measuring the signal level and/or quality of neighbouring base stations (BTS) at a receiver of a mobile station (MS), comparing the measurement results thus obtained and other variables of the connection with handover criteria, and performing a handover from the source cell to the target cell, when the pre-set handover criteria are met. The method of the invention is characterized by determining at least one error connection possible for the connection in a potential target cell for the handover, determining at least one handover criterion on the basis of the determined error correction of the potential target cell, and setting the error correction of the connection in the target cell (BTS2) as said error correction of the base station of the target cell. The invention further relates to a mobile communication system for performing handover.

    • Within a cellular network, an incoming voice mail message is received at a voice mail server (20), adapted into a format suitable for transmission by a network connection which does not meet a delay requirement for delay sensitive information, dispatched to a mobile station (30), and received, readapted and stored thereat within a storing means (35). Adaptation, transmission, reception and readaptation conform to standards such as the GPRS and the UMTS. The voice mail message is dispatched directly to the mobile station (30) via an IP address of an ISDN address thereof. In this manner, instead of dispatching a message via the SMS, the sending of an adapted voice mail message directly to a mobile station (30) and storing it thereat makes it possible to avoid that a user has to poll a service center by calling in order to have the message delivered.
