Abstract

In A speed-dependent hand over procedure for hierarchic cell structures, a check is carried out given a mobile station traveling into A radio coverage domain of a micro cell to see whether the radio coverage of the mobile station with respect to the micro cell has significantly or insignificantly improved within a time interval. In case of a significant improvement, the micro cell is blocked for the rapidly traveling mobile station.
