Bandwidth Parts (BWPs) are used for the transmission and measurement of positioning reference signals during a positioning session. A location server may obtain relevant BWP information, such as the active BWP or a list of configured BWPs, from one or more base stations and/or the user equipment (UE) for the positioning session. The location server may provide assistance data to the UE that is determined based on the BWP information, so that the UE may measure PRS signals from intra-frequency base stations. The location server may further determine a preferred BWP or prohibited BWPs, which may be forwarded to the serving base station to control the BWPs that are used during the positioning session.

Methods and systems are disclosed which determine a location context of a mobile device such as a smartphone. The method may include the following steps: collecting sensor specific data from sensors of the mobile device, applying the sensor specific data to a decision function, and determining, as an output of the decision function, a location context of the mobile device. Also disclosed is a non-transitory computer readable medium containing instructions that when executed causes one or more processors of the mobile device to perform the disclosed method.

Methods and apparatuses for position determination and other operations. In one embodiment of the present invention, a mobile station uses wireless signals from a plurality of wireless networks (e.g., with different air interfaces and/or operated by different service providers) for position determination (e.g., for data communication, for obtaining time and/or frequency information, for range measurement, for sector or altitude estimation). In one embodiment of the present invention, mobile stations are used to harvest statistical data about wireless access points (e.g., the locations of mobile stations that have received signals from the wireless access points, such as from cellular base stations, wireless local area network access points, repeaters for positioning signals, or other wireless communication transmitters) and to derive location information (e.g., position and coverage area of the wireless access points) for the wireless networks from the collected statistical data.

A system and methods for estimating the location of a mobile device are disclosed. In accordance with one embodiment, a mobile device receives an ultrasound signal lacking an identification of the source of the ultrasound signal. One or both of the mobile device or a server identify which of a plurality of beacons transmitted the ultrasound signal based on the time at which the mobile device received the ultrasound signal and the time at which the mobile device received a wireless electromagnetic signal prior to receiving the ultrasound signal. One or both of the mobile device or the server estimate a location of the mobile device based on the identified beacon and on the times at which the mobile device received the wireless electromagnetic and ultrasound signals.

An information handling system operating a diverse wireless location determination system, comprising receiving an instruction to determine a location of an endpoint information handling system having a plurality of network interface device modules supporting a plurality of wireless network protocols, a processor executing instructions to aggregate data including detected time of flight (TOF) signal distance and signal quality values relating to signals exchanged between the endpoint information handling system and a plurality of diverse wireless protocol access points, the processor to determine at least three diverse wireless protocol access point signals meet a signal quality threshold, where at least two of the diverse wireless protocol access points operate under different wireless protocols, and the processor conducting weighted multiangulation or multilateration utilizing the detected TOF signal distances of the exchanged signals based on the detected signal quality category and type of wireless protocol for the exchanged signal.

A location system is disclosed for commercial wireless telecommunication infrastructures. The system is an end-to-end solution having one or more location centers for outputting requested locations of commercially available handsets or mobile stations (MS) based on, e.g., CDMA, AMPS, NAMPS or TDMA communication standards, for processing both local MS location requests and more global MS location requests via, e.g., Internet communication between a distributed network of location centers. The system uses a plurality of MS locating technologies including those based on: (1) two-way TOA and TDOA; (2) pattern recognition; (3) distributed antenna provisioning; (5) GPS signals, (6) angle of arrival, (7) super resolution enhancements, and (8) supplemental information from various types of very low cost non-infrastructure base stations for communicating via a typical commercial wireless base station infrastructure or a public telephone switching network. Accordingly, the traditional MS location difficulties, such as multipath, poor location accuracy and poor coverage are alleviated via such technologies in combination with strategies for: (a) automatically adapting and calibrating system performance according to environmental and geographical changes; (b) automatically capturing location signal data for continual enhancement of a self-maintaining historical data base retaining predictive location signal data; (c) evaluating MS locations according to both heuristics and constraints related to, e.g., terrain, MS velocity and MS path extrapolation from tracking and (d) adjusting likely MS locations adaptively and statistically so that the system becomes progressively more comprehensive and accurate. Further, the system can be modularly configured for use in location signaling environments ranging from urban, dense urban, suburban, rural, mountain to low traffic or isolated roadways. Accordingly, the system is useful for 911 emergency calls, tracking, routing, people and animal location including applications for confinement to and exclusion from certain areas.

A location server device includes a memory circuitry, a processor circuitry, and an interface.

The interface is configured to transmit, to the at least one selected positioning unit, an activation signal. The activation signal indicates to the at least one selected positioning unit to activate transmission of one or more second positioning signals at a second frequency that is different from the first frequency.
