Subscriber data bases with large subscriber-data fluctuations require special strategies to ensure optimum utilization of the available storage space while keeping access times as short as possible. In addition, subscriber anonymity is to be ensured. A method is provided for assigning a memory location to each subscriber via a temporary subscriber number (4-byte TMSI). The invention proposes an internal structure for the TMSI which consists of several logically independent elements which, on the one hand, permit as large an addressing range as possibly and, on the other hand, preclude any confusion of data records or any identification of the subscriber. In addition, the TMSI is constantly changed. With a 32-bit TMSI, up to 10 6 subscribers can be unambiguously addressed.
