摘要： The present invention relates to a method and system for early compression of a header portion of first data packet(s) transmitted after establishment of a packet data connection. A compression information is obtained from a signaling used to establish at least a part of said packet data connection, and is used for the early compression of the header portion. Thereby, even the first data packet(s) can header-compressed to thereby enhance compression efficiency and reduce delay in transmission-window based packet connections with a slow start phase.
摘要翻译：本发明涉及一种用于在建立分组数据连接之后发送的第一数据分组的报头部分的早期压缩的方法和系统。从用于建立所述分组数据连接的至少一部分的信令获得压缩信息，并且用于头部部分的早期压缩。因此，即使第一数据分组也可以被头压缩，从而提高压缩效率，并减少基于传输窗口的分组连接中的慢速启动阶段的延迟。

摘要： The present invention concerns a data communication method for communicating packetized data via an interface (Air I/F) between a transmitter (Transmitter Side (Server)) and a receiver (MS Side), wherein communication relies on a layered communication protocol stack comprising at least two protocol layers (Application, Link Layer) of different hierarchy level, wherein at least data communication on a lower one of said layers (Link Layer) adopts a retransmission scheme for data packets for which an acknowledgment of receipt was not received at the transmitter, the method comprising the steps of initializing the retransmission scheme of the lower one of said layers by setting a condition parameter, wherein fulfilling the condition defined by the condition parameter represents an indication as to how to control the retransmission scheme, wherein initializing comprises setting said condition parameter of the lower one of said layers according to information forwarded from said higher one of said layers to said lower one of said layers, transmitting packet data from the transmitter via the interface to the receiver according to the retransmission scheme of said lower one of said layers, detecting that said condition is fulfilled during transmitting, and controlling said retransmission scheme of said lower one of said layers in response to said detecting. Also, a corresponding system constituted by correspondingly adapted transmitters and receivers is proposed.
