1. A method of improving reliability in mobile device positioning, comprising:

  • generating, by a mobile device, position data for a device based on signaling between the mobile device and a first access point;

    receiving, at the mobile device from a positioning server, a first access point position reliability state associated with the first access point;

    determining, by the mobile device, a reliability of the position data based on the first access point position reliability state and an estimated location of the first access point;

    determining, by the mobile device, a threshold reliability requirement of an application associated with the mobile device;

    comparing, by the mobile device, the reliability of the position data to the threshold reliability requirement of the application;

    providing, by the mobile device to the application, the position data of the device based on the comparison;

    wherein the position data of the device comprises a first position of the mobile device, the method further comprising;

    determining, by the mobile device, a second position of the mobile device that is not based on signaling between the mobile device and the first access point;

    comparing, by the mobile device, the first position of the mobile device to the second position of the mobile device;

    generating, by the mobile device, a consistency metric based on the comparison of the first position of the mobile device to the second position of the mobile device, wherein the consistency metric is based on the measurement history of a given Local Area Network Wireless Access Point (LAN-WAP) including an accumulated number of reliable and consistent measurements;

    indicating that the first position is within a threshold distance of the second position and the first access point position reliability state is below a threshold, wherein the consistency metric indicates that the positioning server should increase the first access point position reliability state to a higher access point position reliability state; and

    sending, by the mobile device, the consistency metric to the positioning server.
