Appl. No.:

12/732849

Inventors:

International Classification:

H04M 3/16
H04W 24/00

US Classification:

455410, 4554563

Abstract:

A mobile device may communicate with a location server during location based services (LBS) operations using a secure identifier. The secure identifier abstracts identification information of the mobile device and/or identification information of a user of the mobile device in instances that the mobile device and/or user identification information are deemed protectable from the location server. The location server may be operable to store location data corresponding to the mobile device and/or the user in a location reference database based on the secure identifier. The secure identifier may comprise a unique value, which may be randomly generated. The secure identifier may also be generated based on the mobile device and/or user identification information, by applying, for example, encryption algorithms to the mobile device and/or user identification information. Service providers for the mobile device may retrieve the abstracted mobile device and/or user identification information from the secure identifier.

US Classification:

705 18, 705 43, 705 44, 726 4

Abstract:

Aspects of a method and system for authorizing network transactions based on device location are provided. In this regard, a request may be received to approve a transaction that was initiated from a first communication device and comprises a need to access an account. In response to the request, a second communication device that is associated with the account may be determined, and it may be determined whether to approve the transaction based on received data relating to the identity and location of the second communication device. The transaction may be associated with the second communication device via a database stored on the location server. The transaction may be approved in instances that the first communication device is in a location associated, via the database, with the second communication device. The transaction may be approved in instances that the first communication device is in substantially the same location as the second communication device.

H04M 1/66

US Classification:

705 44, 701300, 455411

Abstract:

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.

International Classification:

H04W 64/00

US Classification:

4554563

Abstract:

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.

International Classification:

H04W 24/00

US Classification:

4554561

Abstract:

A transmitting communication device may iteratively adjust its transmit power, and may estimate, based on iterative transmit power adjustment, relative location of a receiving communication device. The transmit power may be initialized to a maximum value, and the transmit power may be iteratively reduced until connectivity with the receiving communication device is lost. The loss of connectivity may be determined based on reception of responses to ping messages transmitted by the transmitting communication device. The transmitting communication device may authenticate the receiving communication device and/or a user of the receiving communication device. The authentication may comprises utilizing transmit power adjustment and/or relative location estimation therefrom to ensure that a separation between the devices does not exceed a maximum value. The transmitting communication device may generate location info associated with the receiving communication device based on the relative location estimation, and may communicate the location info to a location server.

International Classification:

G01S 19/05

US Classification:

34235742

Abstract:

A communication device within a GNSS group propagates GNSS assistance data to one or more other communication devices in the GNSS group. The GNSS assistance data includes ephemeris received from one or more GNSS satellites and/or predicted ephemeris. As a source device, the communication device generates, and/or acquires from other resources such as a remote location server, the predicted ephemeris. As a destination device, the communication device receives existing GNSS assistance data from a source device and/or other communication devices in the GNSS group. A GNSS position for the communication device and corresponding time information are used to refresh the received GNSS assistance data. In instances where the communication device further acts as a relay device, the refreshed GNSS assistance data is relayed to other communication devices over wired and/or wireless direct device-to-device connections utilizing appropriate communication technologies such as WiFi, Bluetooth and/or Bluetooth low energy.

Abstract:

A multi-radio mobile device comprises a plurality of different radios. When a location update occurs, the multi-radio mobile device, at a specific location, acquires location-based radio information from a remote location server. The multi-radio mobile device selects a radio for use in the specific location based on the acquired location-based radio information comprising available radios in the specific location and radio weights. The radio is selected from the available radios based on the radio weights in the specific location. Transmissions of a desired service are received in the specific location utilizing the selected radio. Location-based radio measurements reports to the remote location server are generated utilizing signal strength measurements for the received signals. Radio quality information of the available radios is calculated by the location server utilizing location-based radio measurement reports from associated users. The radio weights of the available radios are determined based on the calculated radio quality information.
