A method, a power adapter and a system for determining a location of the power adapter are provided. The method includes: determining whether the power input plug is engaged with an AC power output wall socket of a power source; if the power input plug is not engaged with the AC power output wall socket, instructing the beacon circuit module to broadcast tag information corresponding to the power adapter; else if the power input plug is engaged with the AC power output wall socket, enabling the tag reader to read a tag circuit of the power source; identifying an identification number detected from the tag circuit; determining a location of the power adapter according to the identification number and a location mapping table; sending a plug notification to a remote control center; and instructing the beacon circuit module for receiving a further tag information of a further power adapter.

Systems and methods for providing timely location estimates when a user equipment initiates a call to an emergency number are disclosed. The system enables a user equipment and network nodes (e.g., eSMLC/LMF) to send multiple location responses instead of just one so that the PSAP can benefit from accurate location techniques in a timely manner. For example, when a user equipment is located in an outdoor environment, it can immediately send its A-GNSS location after meeting quality-of-service (QoS) criteria, and the eSMLC/LMF can forward the location estimate to the PSAP immediately without first waiting for all of the other location estimates. When location estimates become available from other technologies (e.g., E-CID, or DBH, or both), the eSMLC/LMF can send to the PSAP another location response for that technology. As a result, the PSAP can always have the most accurate and up-to-date location information available to timely and accurately respond to emergency calls.

In an aspect, a user equipment (UE) receives a spoofing alert message from either a server or an internet-of-things (IOT) device that indicates whether a spoofed Global Navigation Satellite System (GNSS) condition is present. Based on determining that the spoofing alert message indicates that a spoofed GNSS condition is present, the UE determines, based on the spoofing alert message, a location of a spoofer broadcasting a spoofed GNSS signal, determines, based on the location of the spoofer and a current location of the UE, that the UE is within a receiving area of the spoofed GNSS signal, and determines a position of the UE without using the spoofed GNSS signal.

The present disclosure relates to determining proximity in a smart car system, and a method for operating a vehicle system comprises the steps of: receiving at least one signal transmitted by a user apparatus; transmitting measurement data for the at least one signal to a management apparatus; and receiving updated mapping data from the management apparatus for the measurement data and proximity data.

Embodiments described herein provide for system and methods to crowdsource the location of wireless devices and accessories that lack a connection to a wide area network. One embodiment provides for a data processing system configured to perform operations comprising loading a user interface on an electronic device, the user interface to enable the determination of a location of a wireless accessory that is associated with the electronic device, generating a set of public keys included within a signal broadcast by the wireless accessory, the signal broadcast during a first period, sending the set of public keys to a server with a request to return data that corresponds with a public key in the set of public keys, decrypting the location data using a private key associated with the public key, and processing the location data to determine a probable location for the wireless accessory.

In one example embodiment, a certified location service enables a mobile device to access a location-based service when a determined location meets a location requirement and an overall confidence score for the determined location exceeds a confidence threshold. A data package is received including identifiers of beacons observed by the mobile device, and a location of the mobile device is determined based on a calculated location of one or more of the beacons. An overall confidence score for the determined location is calculated based on one or more individual confidence scores for the one or more beacons used in determining the location or composite confidence scores for types of the one or more beacons. The determined location and the overall confidence score are provided to one or more provider servers that allow the mobile device to access a location-based service based thereon.

A method and system is disclosed for determining a probability that an encountered platform was of a specific type given that a plurality of emitters exist on the platform and each emitter has a computed probability that it is of each of a set of types. A preprocessing stage operates on a description of the environment and determines the probability of a set of events that are independent of any observation. A runtime processing stage uses the terms computed in the preprocessing stage along with data assembled from a set of observations to determine the conditional probability that a particular platform type was the type encountered.

Systems and methods for determining a location of a mobile computing device requesting emergency services are provided. A mobile computing device may receive an indication of a request for emergency services from a user of the mobile computing device. The mobile computing device may receive a first wireless signal from a first device. The wireless signal may include an indication of a first geographic position associated with the first device. The mobile computing device may determine a location associated with the mobile computing device based on the indication of the first geographic position associated with the first device, and may send the determined location to a provider of emergency services.

A system and method for an anti-hopping algorithm for an indoor localization system. A method includes receiving a plurality of beacons, each of the plurality of beacons is received from a respective transmitter, pre-filtering the plurality of beacons to identify a subset of the plurality beacons that exceed a minimum signal threshold, and comparing a signal strength of each beacon of the subset to a strongest signal strength threshold of a currently assigned beacon. A method includes selecting a beacon from the subset, the selected beacon has been detected to exceed the strongest signal strength threshold of the currently assigned beacon a predetermined consecutive number of times, and assigning a location to the receiver, the location corresponds to a location of a transmitter of the selected beacon.

Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine its position by receiving locations from one or more other UEs capable of network-based positioning. For example, a second UE may determine its location using network-based positioning and may transmit its location information to the first UE. The first UE may determine its location based on the received location information (e.g., by calculating a weighted average of different locations, by setting its location to be the same as the received location). In some cases, the first UE may receive location information from other UEs during or after a discovery process with other UEs. In some other cases, the first UE may receive messages (e.g., periodic safety messages) from the other UEs, and the messages may each include location information of the respective other UEs.
