Embodiment Construction
[0027] The disclosed embodiments facilitate positioning related operations, in part, by facilitating AP mobility indication. A device may be considered mobile if the device is not stationary. The term "mobility indication" is used to refer to a classification or classification of mobility and / or a characterization of mobility. For example, a mobility indication may indicate that the AP is mobile. As another example, the mobility indication may provide the speed and direction of travel of the AP. As another example, the mobility indication may provide a range of displacement and / or a radius of displacement over which the AP moves. For example, coordinates (eg, latitude, longitude, altitude) defining an area or range over which the AP moves may be provided as part of the mobility indication. In some embodiments, the range may be specified as some function of one or more coordinates. For example, coordinates (eg, center) and radius may be provided to indicate an area (eg, cir...

Methods for mobility indication of wireless Access Points (APs) are disclosed. An AP may determine mobility indication information, based, in part, on at least one of: configuration information on theAP pertaining to mobility; and / or wireless signal measurements associated with the AP, and / or captured images associated with the AP, and / or sensor measurements associated with the AP. The AP may transmit the mobility indication information for the AP. The mobility indication information may indicate that the AP is mobile and / or characterize the mobility. The mobility indication information may further include a request to remove information associated with the AP from location determination databases, location assistance databases, and / or base station almanacs. Disclosed methods also pertainto User Equipments (UE), which may receive wireless signals with mobility indication information associated with an AP; and determine a suitability of the AP for determining the UEs location based onthe received mobility indication information.
Description
[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority to US Non-Provisional Application No. 15 / 096,203, filed April 11, 2016, entitled "Access Point Mobility Indication." The above applications are all assigned to the assignee of the present case, and all of them are incorporated herein by reference. technical field [0003] The subject matter disclosed herein relates to position determination, and in particular, to position determination in environments that include mobile and / or autonomous wireless access points. Background technique [0004] There is often a need to perform positioning functions on user equipment (UE), such as mobile terminals, cellular telephones or other mobile devices. The terms "location" and "position" are synonymous and are used interchangeably herein. To estimate the location of the UE, various techniques may be used, such as Advanced Forward Link Trilateration (AFLT), Round Trip Time (RTT) ...
