Abstract: While a SIM-enabled cellular device is in a disable-SIM-card-updates mode of operation during which SIM-card updates should be disabled, the SIM-enabled cellular device blocks updates of a cellular Subscriber Identity Module (SIM) card of the SIM-enabled cellular device. Upon determining that the SIM-enabled cellular device is no longer in the disable-SIM-card-updates mode, the SIM-card updates are no longer blocked. SIM-card updates may be blocked by blocking the following types of messages received by the SIM-enabled cellular device from a cellular network: Short Message Service (SMS) SIM, Short Message Service (SMS) SIM update, Bearer Independent Protocol (BIP) packet update, and Access Point Name (APN) packet update. The SIM-enabled cellular device may be an automotive Telematics Control Unit (TCU). The automotive TCU may enter the disable-SIM-card-updates mode due to an automotive telematics emergency call.

Abstract: The invention discloses an ultra-wideband (UWB) positioning system, UWB base stations (BSs), UWB tags and the operation methods thereof. Because the present invention uses a server aware of the positions of all BSs to determine the BSs that performs distance measurement, and the server assigns different time slots to each BS that performs distance measurement, the present invention can avoid collisions between the BSs in the process of distance measurement. Furthermore, because the tag can select a specific time slot to access the UWB positioning system by monitoring the UWB signals in the air, the present invention can reduce collisions between the tags. By carefully planning the system frames and subframes of the time division multiplexing system, and sophisticatedly arranging the operation timings of the BSs and the tags, the present invention provides practical and stable UWB positioning system, BSs, and tags.

Abstract: A user equipment (UE) initiates a positioning session based on ranging in a distributed system of UEs. The positioning session includes a plurality of anchor UEs with known positions that provide information including ranging information and their positions to the initiator UE in post-ranging messages. The initiator UE identifies anchor UEs that provide information that does not significantly contribute to the final position estimate for the initiator UE. The initiator UE, for example, may generate position estimates and associated accuracy levels for different subsets of anchor UEs and may use the accuracy levels to identify a subset of anchor UEs that may be used for positioning in place of the full set of anchor UEs without a significant loss of accuracy. Selected UEs are excluded from providing post-ranging messages in subsequent positioning sessions to reduce signaling overhead and improve efficiency.

Abstract: An approach is disclosed for determining a non-specific device location according to an observed mobility pattern derived from non-positioning related sensors. The approach involves, for example, determining non-positioning related sensor data collected from one or more sensors of a device. The approach also involves processing the non-positioning related sensor data to determine an observed mobility pattern. The approach further involves making a determination that the observed mobility pattern corresponds to reference data associated with a non-specific location, the non-specific location being at a designated location specificity level. Based at least on the determination, the approach further involves providing an output indicating that the device is located at the non-specific location.

Abstract: A method for performing contact tracing. An analysis system performing the method receives geo-temporal data comprising location data points for various wireless terminals, including the wireless terminal being used by a person diagnosed as having a specified disease and the wireless terminals of people who possibly have come in contact with the infected person. Based on filtering the geo-temporal data, the analysis system generates relatively-condensed mobility profiles that are representative of each person's locations and movements, and analyzes the mobility profiles. Through careful selections of various parameters based on the disease that is being analyzed, the mobility profiles are used instead of the relatively large amounts of geo-temporal data, to represent users of wireless terminals and to determine their interactions in regard to disease transmission.
