The mobile communication network (BSS, MSC) dynamically adjusts (Handover CMD/Additional Assignment) the channel configuration assigned to the mobile station (MS) for the data call and consisting of one or more traffic channels, within the limits of said minimum and maximum requirements of the data channel, depending on the changing allocation state of the resources of the mobile communication network.

Abstract: A method of paging a mobile station to establish a packet-switched connection in a mobile telephone network that supports a circuit-switched connection and a packet-switched connection. To establish a mobile-terminated circuit-switched connection, the mobile telephone network sends the mobile station a page request, as a result of which the mobile station switches to standby mode for a circuit-switched connection. To save the batteries and to reduce the need of processing, the mobile station listens only to the paging channels of the circuit-switched connection. To establish a mobile-terminated packet-switched connection, the mobile telephone network sends the mobile station a page request via a circuit-switched connection and subsequently sends the mobile station the additional information commanding the mobile station to switch to a packet-switched connection. After detecting the additional information, the mobile station switches to the packet-switched connection.

Abstract: 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.

Abstract: 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.
