Abstract
Position of a WLAN access point (AP) is determined by reference to user equipment devices (UEs) in communication with the AP and with a radio network interworked with the WLAN. The AP position may be assumed to be the same as position of any UE in communication with the AP. UE positions may be averaged for a plurality of UEs, a plurality of positions of the same UE, or a combination of such UE positions. Round-trip time (RTT) may be measured between a plurality of UEs and the AP, and the AP position may be trilaterated from the RTT measurements and the UE positions. AP position may also be trilaterated froni positions of the same UE in combmation with RTTs between the AP and the UE, measured at different times. The computations of the AP position may be hosted at the WLAN or the radio network.
