1. A mobile device-implemented method comprising:
- receiving signals at a mobile device from one or more access points;
computing one or more positioning quality parameters by analyzing the received signals, the one or more positioning quality parameters being indicative of respective error levels corresponding to respective one or more estimated positions of the mobile device;
determining based, at least in part, on the computed one or more positioning quality parameters whether the mobile device is located inside or outside at least one of one or more pre-defined geographic areas respectively associated with the one or more access points, wherein determining whether the mobile device is located inside or outside the at least one of the one or more pre-defined geographic areas respectively associated with the one or more access points comprises determining whether the mobile device is located inside or outside the at least one of the one or more pre-defined geographic areas based on a determination of whether the computed one or more positioning quality parameters, indicative of the respective error levels corresponding to the respective one or more estimated positions of the mobile device, exceed one or more pre-determined error thresholds; and
switching an operating mode of a positioning engine between a single-fix mode and a tracking mode based on determination of whether the mobile device is located inside or outside the at least one of the one or more pre-defined geographic areas, wherein switching the operating mode further comprises disabling transitions between the single-fix mode and the tracking mode based on;
one or more values for at least one historical positioning quality parameter for one or more previous fixes,a determination of whether a difference between a first horizontal estimated position error (HEPE) value for a first time instance, preceding a current time, and a second HEPE value for a second time instance preceding the first time instance, is less than a pre-determined transitioning threshold,or both.
