The present invention relates to a method and a system for transmitting
data packets between a mobile station and a current base station of a
mobile radio system. The mobile station repeatedly transmits measurement
reports each containing measurement data relating to a number of adjacent
base stations to the current base station. A later measurement report
contains reference data for at least one adjacent base station whose
measurement data have already been received from the current base station
in an earlier measurement report and stored, the reference information
referring to the measurement data of the respective earlier measurement
report. As a result, measurement data relating to a relatively large
number of adjacent base stations can be transmitted in the measurement
reports or the transmission bandwidth can be reduced.
