    摘要: For transmitting information about the neighbouring cells to mobile stations, a base station of a cellular radio system creates a message (27, 27′) containing information about the neighbouring cells and transmits it to the mobile station. In addition to the transmission frequencies used in the neighbouring cells, the base station includes in the message other information characterizing the neighbouring cells (32a, 32b, 32c, 34). In particular, the base station includes in the message information about the quality of service offered to mobile stations by each of the neighbouring cells mentioned in the message. On the basis of the message, the mobile station makes a preliminary selection of a group of the most advantageous new cells and performs measurements among this preliminary selection in order to find a suitable new cell (41, 47). If the measurements show that there is at least one suitable new cell among the preliminary selection, the mobile station selects a new cell from this group (42). If the measurements show that there are no suitable new cells in this group, the mobile station selects a new cell from another group of cells than the preliminary selection (43, 48).
