The invention provides a cellular communication system (200) where handovers are facilitated in regions with many small cells. According to the invention entry cells (209,213) to a region, typically a building, are defined and allocated identical frequencies. A mobile station entering the region will handover to this frequency and all entry cells (209, 213) will support the mobile station in parallel. Following the handover, the system may determine a serving cell and the mobile station will subsequently be supported by this cell only, thereby freeing up resource in the other entry cells (209, 213). The invention is specifically applicable but not limited to a GSM system using simulcast techniques. <IMAGE>
