Abstract: An apparatus for testing a device (DUT) includes a peripheral controller configured to communicate with an application embedded in the DUT. The application is configured to run self-diagnostic tests. An audio interface is arranged to transmit audio codes between the apparatus and the DUT on the basis of the tests, wherein the peripheral controller is coupled to the audio interface, being configured to encode and decode the audio codes. A method of testing a DUT includes running a DUT embedded application configured to run self-diagnostic tests. Running the application comprises transmitting encoded audio command signals via an audio interface from a testing apparatus to a microphone configured with the DUT to initiate self diagnostic tests, receiving audio response signals from the DUT generated on the basis of the tests via an audio interface configured with the testing apparatus, and decoding the received audio response signals by a peripheral controller.

Abstract: Methods, apparatus, and computer program products for determining a position of a mobile device in a network service area are described. An example of a method for determining the position of the mobile device includes receiving a positioning request for the position of the mobile device and, in response to receiving the positioning request, receiving signal characteristic measurements, estimating an a priori mobile device position area based on the signal characteristic measurements, determining a selected AD model, and determining the position of the mobile device using the selected AD model.

Abstract: A mobile device in a moving vehicle initializes a Global Navigation Satellite System (GNSS)-Inertial Navigation System (INS) system while the vehicle is in-motion with the orientation of the mobile device with respect to a global reference frame. The mobile device uses gyroscope measurements made while the vehicle is turning to determine a gravity vector. The gravity vector and accelerometer measurements may be used to determine a forward vector for the mobile device. A north vector is determined using the GNSS measurements. After the GNSS-INS system is calibrated, the mobile device may be positioned with respect to the vehicle. The orientation of the mobile device, prior to repositioning, may be compared to a current orientation, determined while the vehicle is in motion, in order to determine whether the GNSS-INS system should be re-initialized.

Abstract: Embodiments disclosed pertain to apparatuses, systems, and methods for dynamically characterizing a mobile station (MS) in a wireless network by determining the variability of measured Round Trip Time (RTT) parameter values, the variability of measured Received Signal Strength Indicator (RSSI) parameter values and other determined characteristics and classifying the MS into at least one of a plurality of classification groups based on the values of at least one of the RTT variability, the RSSI variability, or the other determined characteristics. The classification groups associated with a mobile station may be used to selecting a positioning method to determine the position of the MS.

Abstract: A method being for facilitating positioning determination of a UE includes: obtaining motion information indicative of motion of the UE; obtaining positioning information based on positioning signals received by the UE; determining a validity status of map data based on whether the positioning information, the motion of the UE, and the map data, that include locations of physical environmental features, are consistent, wherein the validity status is determined to be valid in response to the positioning information, the motion of the UE, and the map data being consistent; and determining at least one of a position estimate for the UE, or a direction of motion of the UE, based on the map data and based on the validity status being valid.
