Abstract
The invention relates to a method of implementing a handover in a cellular radio system. The cellular radio system has at least on cell (Cd) which comprises at least two subcells and in which all available frequencies are dynamically used. The cellular radio system comprises in each cell (C, Cd) at least one base station (BTS) which communicates with subscriber terminals (MS) located within its area. A handover from an old cell to a new cell (Cd) applying dynamic channel allocation is characterized in that only BCCH carrier frequency time slots comprising control channels are transmitted all the time in all subcells of the cell(Cd). The method allows traffic channels of a BCCH carrier frequency to be dynamically reused in subcells of the cell (Cd), providing the improved system capacity.
