The method comprises receiving and storing the time and self-location of an emergency (e911) call message from a mobile communication device. The method then retrieves the time and self-location information and the trilateration data associated with the mobile communication device that originated the e911 call message. An estimated position is then calculated from the trilateration data by using a trilateration position estimating model. An error is determined between the self-location and the estimated position of the mobile communication device, whereby the self-location is deemed authoritative. The trilateration position estimating model is adapted based on the error determined and then used to determine the position of a second mobile communication device."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Adaptive feedback in cell tower trilateration locating of mobile communication devices","description":"A method of adapting determination of location of mobile communication devices.
