In the prior art, equipment lists (B, G, W) are searched successively, or a list is searched which contains all equipment numbers (MEI1 to MEIn) along with the respective equipment lists to which they are assigned. Thus mobile stations (MEI1 to MEn) are assigned to one of several equipment lists (B, G, W; black, grey, white list). This assignment must be checked by the mobile switching center (MSC) prior to the establishment of a connection. The present method uses an algorithm where each equipment number (MEI1 to MEIn) is assigned a search key (KEY1 to KEYp; KEY) such that groups of equipment numbers (MEI1 to MEIn) correspond with a respective one of the search keys (KEY1 to KEYp; KEY), and that the search key (KEY1 to KEYp; KEY) covers a number of different structural elements (S1 to Sq; DAT). In a corresponding apparatus for determining the assignment of a mobile station (ME1 to MEn) to equipment lists (B, G, W) containing a number of equipment numbers (MEI1 to MEIn), a memory device (MEM) has as a memory device for different structural elements (S1 to Sq; DAT), and the controller is provided with a converting device (GEN) for generating a search key (KEY1 to KEYp; KEY) from an equipment number (MEI1 to MEIn), with a comparator (COMP) for determining the association of an equipment number (MEI1 to MEIn) with a structural element (S1 to Sq; DAT), and has an access device (ACC) for reading different structural elements (S1 to Sq; DAT) from the memory device (MEM), the access device (ACC) being designed to access the structural elements (S1 to Sq; DAT) by means of a search key (KEY1 to KEYp; KEY).
