Abstract: A method and a system for the localization of a mobile WLAN client, located within a WLAN network of multiple WLAN stations. Static reference points are ascertained by measuring field strengths of the WLAN stations at spatial coordinates, aided by WLAN client(s), and assignment of the measured field strengths to the spatial coordinates in terms of data records. Self-learning ascertainment of further dynamic reference points is obtained by measuring field strengths of the WLAN stations, aided by WLAN client(s) moving through the region of the network, and assignment of the measured field strengths in terms of data records to the respective spatial coordinates calculated for this purpose, in the database server. This may be done to localize a WLAN client by selecting a plurality of nearest matched data records of static and dynamic reference points whose subsequently calculated center of gravity corresponds to the estimated position of the WLAN client.

Abstract: A method and central computer-based platform for providing services of various service providers to one or more subscribers who can be assigned to different communications systems are provided. The method and system involve the provision of location-based services of various service providers to subscribers of various communications systems which can be easily and flexibly controlled. A plurality of subscribers, who can belong to different communications systems, are logged onto a central device to which various service provider(s) are assigned. Authorization data of at least one subscriber, which authorizes the service provider(s) to make one or more services available to the at least one subscriber, are subsequently stored in the central device. Localization data of the logged-on subscribers are transmitted to the central device and stored there. The authorized service providers make services available to the subscribers as a function of the subscriber-based localization data.
