A system for providing real-time always-on location is presented for maintaining the current location of a mobile device, while saving the battery by managing the GPS in a power-saving mode while the device is considered to be stationary. The system also provides a real-time location in an indoor environment where a GPS signal may not be available. Additionally, methods for driving detection are also presented.

Methods and apparatus for transmitting information associated with verified positions of Nodes based upon wireless communications between Nodes included in an array. Values for variables derived from multiple wireless transmissions between Nodes are aggregated, and a position of a particular Node may be determined based upon multiple data sets generated by multiple communications between disparate Nodes. Information is geolocated based upon the respective positions of the disparate Nodes. A user interface may provide a pictorial view of positions of all or some Nodes in an array, as well as associated information.

The present invention relates to a method for obtaining a location using Neighbor Awareness Networking, NAN, and a corresponding system as well as a method carried out by a NAN device and a corresponding NAN device so that a location can be obtained in a simple way. In particular, the method for obtaining a location using neighbor awareness networking, NAN, comprises requesting the location of a target NAN device; determining a cluster of wireless NAN devices comprising the target NAN device as well as one or more anchor NAN devices having predetermined locations to serve as positioning nodes; performing range measurements using the travel times of radio signals between the target NAN device and each of the one or more anchor NAN devices; and obtaining the location of the target NAN device based on the range measurements.

Inter-alia, a method is disclosed comprising: obtaining one or more first fallback objects indicative of a geographic area that is covered by one or more cells of a communication network; obtaining one or more pieces of cell information indicative of a number of positioning requests that a respective cell of the one or more cells has received; determining one or more second fallback objects out of the one or more fallback objects; determining for an area of the respective second fallback object in that the needed level of accuracy for determining a position is not achievable, one or more cells based at least partially on the one or more pieces of cell information; and outputting the determined one or more second fallback objects and/or the determined one or more cells for usage in a generation of a radio map. It is further disclosed an according apparatus, computer program and system.

A graphical near-field identification method and apparatus are provided. The method includes filtering a searched beacon signal according to a preset filtration condition. The method further includes matching a filtered beacon with beacons in all beacon graphs to obtain a beacon graph having a largest beacon matching number and the number of beacons matched with the beacon graph. The method further includes determining whether the number of the beacons matched with the beacon graph is less than a beacon determination minimum number requirement. The method further includes determining whether the number of the beacons matched with the beacon graph meets a beacon graph benchmark number condition. The method further includes determining that an object position is in a scenario where the beacon graph is located. The method further includes estimating a distance to the beacon by using a RSSI value of the beacon signal.

Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. Performance of such devices is improved with reduced time to first fix of location operations in conjunction with low-power operations. In one embodiment, low-power circuitry manages high-speed circuitry and location circuitry to provide location assistance data from the high-speed circuitry to the low-power circuitry automatically on initiation of location fix operations as the high-speed circuitry and location circuitry are booted from low-power states. In some embodiments, the high-speed circuitry is returned to a low-power state prior to completion of a location fix and after capture of content associated with initiation of the location fix. In some embodiments, high-speed circuitry is booted after completion of a location fix to update location data associated with content.

In order to promptly specify, with low power consumption, a location of a wearable device departed from a group, the wearable terminal includes a short-distance radio communicator, a location information report request receiver, a location information acquisition unit, and a long-distance radio communicator. The short-distance radio communicator normally performs short-distance radio communication with another wearable terminal. The location information report request receiver receives an externally transmitted location information report request requesting a wearable terminal to report location information of the local terminal to a specified destination. When the location information report request receiver receives the location information report request, the location information acquisition unit acquires location information of the local terminal. The long-distance radio communicator transmits the acquired location information to a destination specified by the location information report request.

A method of determining a location of a measurement device includes determining, at a server: measurement times of first positioning signal measurements, of first positioning signals from first positioning signal sources and/or a subset of positioning signal sources of second positioning signal sources. The method includes sending at least one measurement command from the server to the measurement device to cause the measurement device to obtain the first positioning signal measurements in accordance with the measurement times and/or obtain second positioning signal measurements of second positioning signals sent from the subset of positioning signal sources. The method includes: receiving, at the server from the measurement device, measurement data corresponding to the first positioning signal measurements and/or the second positioning signal measurements; and determining, at the server, the location of the measurement device based on the measurement data.

A position determination apparatus includes a memory and a hardware processor coupled to the memory. The hardware processor: determines position information on one or more wireless communication devices being located within a target region; judges position movement of the one or more wireless communication devices based on the position information; and transmits, to the wireless communication device whose position movement has been judged to be absent, a decrease instruction signal that causes the wireless communication device to decrease a communication frequency of the wireless communication device.

The invention relates to a method, system and computer program product for determining a distance between persons by means of a plurality of battery powered devices. The device is configured to perform a typical and atypical operating pattern, with the advantage of a longer device operating time.
