Abstract

In a speed-dependent hand over method for hierarchic cell structures, a finding is made to whether mobile stations have traversed a radio coverage domain of a micro cell within a time interval. When the mobile stations are still in the radio coverage domain with respect to the micro cell after the time interval, then a hand over for the appertaining mobile stations into the micro cell is requested.
