摘要:
A servicing communication device may receive a subset of a location reference database that is maintained by a plurality of location servers, and may provide location related data to a mobile device that is communicatively coupled to the servicing communication device based on the received subset. The servicing communication device may determine capabilities and/or requirements of the mobile device, and may generate the location related data based on that determination. The servicing communication device may determine attributes and/or parameters that may affect determination of the subset of the location reference database. The subset of location reference database may be requested based on the determined attributes and/or parameters. The attributes and/or parameters may comprise a location of the servicing communication device. The servicing communication device may determine its location, directly based on GNSS transmissions and/or indirectly based on assisted GNSS (A-GNSS) data received from the plurality of location servers.
摘要:
A mobile device may determine its location, receive transaction related information, and initiate, based on its determined location and/or the transaction related information, a transaction at the current location. The transaction related information may be received from a location server. The mobile device and/or its users may also be authenticated, using the location server. The initiated transaction may be completed automatically, without user input. The device user may also be prompted for authorization and/or information for completing the transaction. The transaction related information may specify if and/or when transactions are to be completed automatically. The mobile device may track user actions via the mobile device, and may generate based on that tracking, user action data pertaining transactions initiated and/or conducted by the user. The generated user action data may be communicated to the location server, and may be used to update the profile data maintained by the location server.
摘要:
Aspects of a method and system for authorizing network transactions based on radio frequency (RF) characterization of a device's location are provided. In this regard, whether to approve a communication device to perform a network transaction may be determined based on results of a comparison between a radio frequency (RE) characterization of a location of the communication device and one or more approved RF characterizations. The RF characterization may be based on information from a plurality of receivers within the communication device. The one or more approved characterizations may be stored in the network device. The RF characterization may indicate a quantity of RF sources detected and identified by the communication device at the location. The RF characterization may indicate signal strength of signals received from RF sources detected and indentified by the communication device at the location.
摘要:
Aspects of a method and system for authorizing transactions based on relative location of devices are provided. In this regard, data relating to a location of a first communication device and data relating to a location of a second communication device may be received, a distance between the first communication device and the second communication device may be determined based on the received data, and whether to approve a transaction may be determined based on the determined distance. The transaction may have been initiated from one of the first communication device and the second communication device, and may comprise a need to access an account. The transaction may be approved in instances that the first communication device and the second communication device are within a predetermined distance of each other. The received data may comprise distance information determined via communications between the first communication device and the second communication device.
摘要:
A mobile device may be operable to collect location data for a RF node and cache the collected location data in the mobile device. Resources that may be utilized for improving the uploading of the cached location data to a location server may be determined by the mobile device. The cached location data may be communicated, to the location server for updating a location database, by the mobile device utilizing the determined resources. The mobile device may determine and utilize an opportunistic transport based on a data usage and/or an access. The mobile device may store a subset of the location database locally for comparing with the cached location data for redundancy. The compared location data may be transmitted by the mobile device to the location server for updating the location database if the compared location data are not redundant data.
摘要:
A mobile device may be operable to receive historical location trail information of a building. A location of the mobile device within the building may be determined by placing, moving or snapping a reference location of the mobile device onto a trail according to the received historical location trail information. The historical location trail information may be acquired from a location server. The historical location trail information stored in the location server may be generated using a plurality of location samples that are provided by one or more other mobile devices that have been within the building. The historical location trail information may also be acquired from an indoor map of the building that is used by the mobile device for navigation within the building. The determined location of the mobile device may then be utilized by the mobile device to navigate within the building for location-based services.
摘要:
A location server may be operable to refine a location for a RF node based on a weight applied to one or more location samples that are received from one or more mobile devices. The received location samples may be weighted based on a manufacturer and/or a model information of each of the mobile devices, properties and/or conditions of a RF environment associated with each of the mobile devices, a GNSS dilution of precision, motion sensors used by each of the mobile devices and/or a geometrical population condition associated with each of the mobile devices within range of the RF node. A valid location for the RF node may be generated utilizing the weighted location samples. The location server may update location information for the RF node, which may be stored in a location database, utilizing the valid location for the RF node.
摘要:
A mobile device may be operable to determine, based on a known location of the mobile device, a location for a RF communication device that communicates with the mobile device, whenever the mobile device is within proximate range of the RF communication device. The determined location for the RF communication device may be stored in a location database in a location server and/or a memory in the RF communication device. The stored location of the RF communication device may then be used to determine a location for other mobile devices that may communicate with the RF communication device and are within proximate range of the RF communication device. The RF communication device may comprise a radio-frequency identification (RFID) device and/or a near field communication (NFC) device. The determined location for the RF communication device may comprise the known location of the mobile device.
摘要:
Methods and systems for stabilizing a GNSS clock by reducing interference are disclosed and may include stabilizing a frequency of a temperature compensated crystal oscillator (TCXO) on a chip in a GNSS device. A clock signal may be generated for the device by temporarily configuring circuitry adjacent to the TCXO at a constant power level. Temperature and electromagnetic interference of the TCXO may be stabilized by the constant power level of the adjacent circuitry, which may be on the chip or external to the chip. The frequency of the TCXO may be stabilized by temporarily disabling the adjacent circuitry. A GNSS clock signal may be stabilized by the configuring of the constant power level while a GNSS location may be calibrated. A GNSS location of a fixed wireless device, such as a wireless access point, may be calibrated utilizing the configured constant power level and shared with other wireless devices.
