Abstract

The invention relates to a mechanism for providing location information regarding mobile terminals, especially regarding WLAN terminals. In order that the known mechanism for locating users of a mobile cellular network could be utilized for locating WLAN terminals, a location service request concerning a WLAN terminal is received and routed by the same network elements that receive and route location service requests concerning users of a mobile cellular network. However, in the case of a WLAN terminal the location service request is diverted to a predetermined network element, where the access point currently serving the WLAN terminal is identified. The location information corresponding to the said access point is then determined, and the location information is returned as the location of the terminal. The location of the serving WLAN access point thus represents the location of the WLAN terminal.
