A method for the improvement of a TCP data transmission process in the case of an interruption of the physical transmission medium, wherein after the establishment of a TCP connection between a client () and a server () a data packet is transmitted from the server () to the client (), wherein the receipt of the data packet from the server () is confirmed by the client () by the transmission of a confirmation message assigned to the received data packet, ACK message, wherein in the case of the transmission of the ACK message at the client () a timer () is started with a default time T, and the same ACK message is repeatedly transmitted to the server (), in case no further data packet has been received from the server () at the client () after expiration of the time T

Method for improving a TCP data transmission in case the physical transmission medium is disconnected

A method and apparatus for configuring services in a mobile terminal of a mobile radio network. Configuration data for services in the mobile terminal is updated by means of a data-switching network element and a data-storage network element, data being transmitted by means of existing signalling or system messages of the mobile radio network.

The invention relates to a method for improving QoS mechanisms during bandwidth allocation in CDMA mobile communication systems, characterized in that the user terminal signals the minimal bandwidth (bit rate) which is required to the mobile communication system and a bandwith within said range is allocated to the radio interface when available. As a result, the opportunities provided by the user terminal and the bandwith available in the radio cell are used as efficiently as possible.
