Transferring compression parameters in a mobile communication system

摘要

The invention relates to a method for transmitting compression parameters in a mobile communication system, comprising a mobile node, a first and a second packet switching node. In the method the second packet switching node is informed of the entry of the mobile node to an area controlled by the second packet switching node. At least one compression parameter is received from the first packet switching node to the second packet switching node. The second packet switching node informs at least one of the at least one compression parameter to the mobile node by way of layer-3 parameter renegotiation for a logical link connection. The benefits of the invention are related to improved reliability of packet data transmission to and from a mobile node.
