| 20080242312 | Updating position assist data on a mobile computing device - A mobile computing device comprises a memory, a processor and a transceiver. The memory is configured to store at least one type of position assist data. The processor is configured to provide a position fix based on the position assist data. The transceiver is configured for wireless communication. The memory is configured to store updated position assist data for the type of position assist data. The processor is operable in a first operating mode in which the type of position assist data is not updated and operable in a second operating mode in which the type of position assist data is updated in response to at least one triggering event. | 10-02-2008 |
| 20090098903 | USING WIRELESS CHARACTERISTIC TO TRIGGER GENERATION OF POSITION FIX - A wireless characteristic of a wireless signal may be used to trigger generation of a position fix. A mobile computing device may include a wireless transceiver, a location determination circuit and a processing circuit. The wireless transceiver may be configured to receive a wireless signal over a short range wireless network from a wireless system. The processing circuit may be configured to detect a change in the wireless signal and, in response to the detected change, to generate a position fix using the location determination circuit. | 04-16-2009 |
| 20090248178 | UPDATING POSITION ASSIST DATA ON A MOBILE COMPUTING DEVICE - A mobile computing device comprises a memory, a processor and a transceiver. The memory is configured to store at least one type of position assist data. The processor is configured to provide a position fix based on the position assist data. The transceiver is configured for wireless communication. The memory is configured to store updated position assist data for the type of position assist data. The processor is operable in a first operating mode in which the type of position assist data is not updated and operable in a second operating mode in which the type of position assist data is updated in response to at least one triggering event. | 10-01-2009 |
| 20100048231 | Handheld Threading - The present invention determines which messages to display in message threads to a user. An electronic communication device receives and stores numerous SMS messages transported through an SMS network, but the SMS messages are sent without explicit linking information such as a previous message or subject line. A threading module applies threading rules to determine which messages to correlate into an SMS message thread through implicit link information. The threading rules thread outgoing messages sent in response to an incoming message from a user, or incoming messages where a previous outgoing message was sent to the user. An SMS application displays threads in a user interface and indicates messages threads with an icon in one view, and displays an expanded message thread in another view. | 02-25-2010 |
| 20100304730 | SPACE & TIME BASED DEVICE CUSTOMIZATION - Customizing a device based on space and time (e.g., a geographic position of the device at a particular time) is disclosed. In one aspect, geographic position data of a device is obtained. Temporal data that is related to the geographic position data is obtained. An operational mode is selected based on the geographic position data and the temporal data for activation on the device. In some implementations, the operational mode identifies a communication medium. | 12-02-2010 |
| 20110116453 | LOCATION-BASED NETWORK DETECTION - A mobile device establishes communication with a number of wireless cellular networks at particular locations and records the locations and network information associated with the wireless cellular networks. The network information can be used to narrow a search for an available wireless cellular network from a plurality of potentially available wireless cellular networks when the mobile device is operating at a stored location. In one aspect, a Radio Frequency (RF) receiver on a mobile device can receive a broadcast radio signal from a transmitter and use the signal to determine an approximate location of the device based on a known location of the transmitter. A match between the approximate device location and wireless cellular network transmitters in communication range of the mobile device can be used to narrow a search for wireless cellular networks. | 05-19-2011 |
| 20110250903 | Selective Location Determination - Methods, program products, and systems for selective location determination are described. A mobile device can determine a location of the mobile device using various techniques. When there is a conflict between the locations determined using different techniques, the mobile device can select a most trustworthy location from the locations, and designate the most trustworthy location as a current location of the mobile device. The mobile device can determine a first location of the mobile device (e.g., a coarse location) using a cell identifier (cell ID) of a cellular network. The mobile device can determine a second location of the mobile device (e.g., a fine location) using one or more media access control (MAC) addresses of a WLAN. The first location and second location can be associated with confidence values that can indicate trustworthiness of the first location and second location. | 10-13-2011 |
| 20120021767 | UPDATING POSITION ASSIST DATA ON A MOBILE COMPUTING DEVICE - A mobile computing device comprises a memory, a processor and a transceiver. The memory is configured to store at least one type of position assist data. The processor is configured to provide a position fix based on the position assist data. The transceiver is configured for wireless communication. The memory is configured to store updated position assist data for the type of position assist data. The processor is operable in a first operating mode in which the type of position assist data is not updated and operable in a second operating mode in which the type of position assist data is updated in response to at least one triggering event. | 01-26-2012 |
