    摘要: In accordance with the disclosed approach, positioning server(s) could receive, from mobile devices, information indicating a plurality of GNSS rescue areas, each respective GNSS rescue area of the plurality of GNSS rescue areas corresponding to a respective geographic area visited by a respective one of the mobile devices in which (i) at least one GNSS-based position estimate is or was unavailable and (ii) the respective mobile device had demand for positioning data of at least a particular quality level. Given this, the server(s) could generate a GNSS rescue map representing radio data for the plurality of GNSS rescue areas. In this way, the server(s) could transmit, to a mobile device, an offline radio map representing a subset of the GNSS rescue map, to provide radio data for at least one of the GNSS rescue areas or portion thereof.

    摘要: A computing device obtains an instance of radio observation data and an associated circumstance parameter. The instance of radio observation data indicates an observed signal strength a radio node observed by a mobile device. The circumstance parameter indicates a characteristic of motion of the mobile device and/or a characteristic of the environment about the mobile device when the instance of radio observation data was captured. The computing device determines a context associated with the instance of radio observation data based at least in part on the circumstance parameter; determining a context-specific signal strength correction based at least in part on the context; generates a corrected signal strength of the radio node based on the observed signal strength and the signal strength correction; and generates and/or updates a radio map based at least in part on the corrected signal strength of the at least one radio node.

    摘要: A method, apparatus and computer program product are provided to accelerate the estimation of a radio model of a beamforming access point within a radio environment, such as a beamforming access point that has been newly added to or relocated. In a method, the presence of a first beamforming access point in a radio environment is determined and information is obtained regarding one or more of a plurality of beams that are transmitted by the first access point. The method then estimates the radio model of the first access point based at least upon: (i) at least some of the information regarding the one or more of the beams transmitted by the first access point and (ii) signal propagation characteristics of one or more existing access points in the radio environment as represented by respective radio models of the one or more existing access points.

    摘要: A method, apparatus and computer program product are provided to accelerate the estimation of a radio model of an access point within a radio environment, such as an access point that has been newly added to or relocated within the radio environment. In the context of a method, the presence of a first access point in a radio environment is determined and the signal propagation characteristics of one or more existing access points in the radio environment are also determined. The signal propagation characteristics are represented by respective radio models of the one or more existing access points. The method also includes estimating the radio model of the first access point based at least upon the signal propagation characteristics of the one or more existing access points in the radio environment as represented by the respective radio models of the one or more existing access points.

    摘要: A network device receives a positioning request associated with a computing device; determines a position estimate of the computing device responsive to the positioning request and based at least in part on at least a portion of a positioning map; and determines whether an offline positioning enablement trigger has been identified. Responsive to determining that the offline positioning enablement trigger has been identified, the network device generates a positioning response that comprises the position estimate and information enabling offline positioning of the computing device at least at a location of the position estimate and provides the positioning response such that the computing device receives the positioning response.
