Abstract: Master Street Address Guide (MSAG)-validated street address data is correlated with real-world geographic (e.g., latitude/longitude) data. Conventional MSAG-validated street address data is processed, or geocoded, into an additional (or integrated) database that associates latitude/longitude information with a particular entry in the existing MSAG-validated database. The association of the lat/lon data may be direct, or indirect using link ID or other unique tags indicating a particular entry in the MSAG-validated database. The geocoding need be performed only once by a service provider, e.g., as part of the deployment of an emergency service system. In this way, the closest public service answering point (PSAP) to a given latitude/longitude position of a wireless or VoIP device may be determined quickly, providing emergency services with the smallest possible reliable response time.

Abstract: A system for automatically correcting a mistaken geocoded location input. A wireless device such as a cell phone ranks possible location input based on edit distance, which is a ‘confidence factor’. If there is no perfect match, then a list of geocode options is returned, preferably sorted by the score. The ‘closeness’ is derived by looking at the edit distance to go from the input to the matched address. Edit distance is defined herein as the number of insertion/deletion/replacement operations to go from input location to the possible matched location. In one embodiment, an option list, or ‘pick list’, may be provided based on an edit distance scoring system. The edit distance scoring system is preferably based on a number of keystrokes difference between the input location name and the possible matched location name.

Abstract: A tiled-map display control with a predictive caching technique that minimizes user wait time and provides at least the illusion of continuous panning, even while map tile images are being loaded. Important components of the tiled 5 map display are its definition and cached use of map tiles, as well as the way that the map tiles are put together on a small screen. Easy, seamless, wait-free and convenient viewing of a map for a user of a wireless device provides information, e.g., mapped traffic conditions. The disclosed embodiments are techniques that have been reduced to practice in both a BREW platform, and then in a J2ME platform, and deployed for operation in major carrier wireless networks. The invention has particular applicability for use in wireless devices with typically smaller display screens requiring the need for panning, and limited bandwidth capabilities of the supporting wireless network.

Abstract: A system for automatically correcting a mistaken geocoded location input. A wireless device such as a cell phone ranks possible location input based on edit distance, which is a ‘confidence factor’. If there is no perfect match, then a list of geocode options is returned, preferably sorted by the score. The ‘closeness’ is derived by looking at the edit distance to go from the input to the matched address. Edit distance is defined herein as the number of insertion/deletion/replacement operations to go from input location to the possible matched location. In one embodiment, an option list, or ‘pick list’, may be provided based on an edit distance scoring system. The edit distance scoring system is preferably based on a number of keystrokes difference between the input location name and the possible matched location name.

Abstract: As part of a handset finder service, a customer will download and install a small application, e.g., handset finder application, onto their wireless device. The first time this handset finder application runs, it registers to receive battery notification events from the device (or if not available, another type of wake-up event, like a timer or SMS wake-up). These events wake-up the application, which will determine whether a “low power” threshold has been reached. When this occurs, the application initiates a location query. The application will submit a determined location to a handset finder server.
