Abstract

The application relates to storage and retrieval of information about access points APs of wireless local area networks WLANs. It is known to store information about WLAN APs, for example fingerprint data, in such a way that the data can be accessed using the BSSID of the WL-AN AP, i.e. the MAC address of the radio interface, as a key. However, malicious manufacturers or users copy existing MAC addresses and thereby duplicate existing BSSIDs. Effectively this means that the BSSID is not globally unique, but the same BSSID may occur in multiple WLAN APs at multiple locations. Therefore, when using the BSSID as a key, an AP may thus occasionally and incorrectly seem to jump from one location to another. This problem is solved by the present application in that the information about APs (Data) is assigned not only to the BSSID (BSSID1, BSSIDM) as the primary key but also to an identifier of region (MCC1, MCCN), such as the mobile country code MCC, as a secondary key.
