Data transmission method and base station system

摘要

The invention relates to a data transmission method and a base station system. The method comprises transmitting radio interface information over a bidirectional data link between a base station and a base station controller. The radio interface information comprises signalling information, user information and error control information. The method is characterized in that the radio interface information is compressed to fit into at least one ATM cell by replacing the original error control information of the radio interface information with simple status information. Other information may also be compressed and inserted into the ATM cell. Realization of the method is exemplified in the DECT system. The invention also relates to the necessary means and their protocol stacks.
