摘要:
Methods and systems are provided that use smartcards, such as subscriber identity module (SIM) cards to provide secure functions for a mobile client. One embodiment of the invention provides a mobile communication network system that includes a mobile network, a mobile terminal, a server coupled to the mobile terminal via the mobile network, and a subscriber identity module (SIM) card coupled to the mobile terminal. The SIM card includes a first key and a second key. The first key is used to authenticate an intended user of the mobile terminal to the mobile network. Upon successful authentication of the intended user to the mobile network, the mobile terminal downloads a function offered from the server through the mobile network. The second key is then used by the mobile terminal to authenticate the intended user to the downloaded function so that the intended user can utilize the function.

A GNSS enabled device that is communicatively coupled to a network, receives time stamps via the network. The time stamps are generated based on reference clock signals within the network. GNSS receiver clock signal frequency may be adjusted based on the time stamps. When GNSS satellite signals and/or SRN signals are not available, the time stamps enable synchronization with GNSS satellites. Network clock signals and/or time stamps may be generated by an access point, a DSL modem, a cable modem and/or a primary reference clock within the network. A series of time stamps may be utilized for adjusting frequencies. Clock signals may be generated for adjusting frequencies based on a comparison between time stamps and oscillator or mixer output. Clock signals are generated for baseband, intermediate and/or RF frequency signal processing. GNSS satellite signals may be demodulated, correlated with a pseudonoise code sequence and/or synchronized based on the time stamps.

A GNSS enabled mobile device moves from a first area where GNSS signal quality and/or level is above a threshold to a second area where GNSS signal quality and/or level is below the threshold. The GNSS enabled mobile device in the second area determines its own location utilizing previous GNSS measurements in the first area. GNSS signals are received to calculate GNSS measurements whenever the GNSS enabled mobile device is in the first area. The calculated GNSS measurements are utilized to determine a location of the GNSS enabled mobile device within the first area. The GNSS enabled mobile device in the second area utilizes the most current GNSS measurements in the first area to determine its own location. Sensors such as an image sensor, a light sensor, an audio sensor and/or a location sensor are used to refine the location of the GNSS enabled mobile device in the second area.
摘要:
A wireless communication device determines its location and communicates the location to other local devices utilizing a nonstandard, standard and/or proprietary protocol in combination with another protocol such as a Bluetooth, RFID, IEEE 802.11 and/or a cellular phone protocol. The location may be determined utilizing a GNSS receiver and/or network device information. A new location may be determined based on the determined location, a relative distance and/or a relative direction to other local devices. Determined location information may be communicated to other devices via a network. The wireless communication device may receive locations and/or corresponding location uncertainties from devices located within a limited range. The received information is utilized to determine a more accurate location. The more accurate location is communicated back to the devices within the limited range and/or to other communication devices.
摘要:
A mobile device may be operable to receive three or more location samples for the mobile device from each of three or more resources. Two or more valid location samples may be selected based on an accuracy indicator associated with each of the received location samples. A location of the mobile device may be determined utilizing the selected two or more valid location samples. A region around each of the received location samples may be determined based on the accuracy indicator and a condition of a geographic environment that is associated with each of the received location samples. Two or more valid location samples among the received location samples may be selected in instances when at least a portion of the region of each of the selected valid location samples overlaps with at least a portion of the regions of each of other selected valid location samples.
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:
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.
