| 20110156950 | Positioning System and Positioning Method - It is an object of the present invention to perform positioning at favorable positioning precision and in a favorable positioning time, according to whether a receiver is indoors or outdoors. A positioning server | 06-30-2011 |
| 20110156951 | Positioning System and Positioning Method - It is an object of the present invention to obtain a positioning result corresponding to the state of a receiver in less time. A positioning server | 06-30-2011 |
| 20110156952 | Positioning System and Positioning Method - It is an object of the present invention to perform positioning at the proper positioning time and positioning precision in response to a requirement with respect to positioning. A positioning server | 06-30-2011 |
| 20110187525 | Search Area Reduction For Estimating the Location of a Wireless Terminal Based On Indoor Detection - A method of using a non-GPS-derived technique to estimate the location of an Assisted-GPS-enabled wireless terminal for the purposes of generating location-specific assistance data for the wireless terminal is disclosed. The wireless terminal then uses the assistance data to acquire and process one or more GPS signals and to derive information that is probative of the wireless terminal's location. The GPS-derived location information is then combined with non-GPS-derived location to form an estimate of the location of the wireless terminal that is better than can be derived from either alone. This combination of GPS-derived and non-GPS techniques is particularly useful when the wireless terminal can only acquire one or two GPS signals because it is not possible to determine the location of the wireless terminal with only two GPS signals alone. | 08-04-2011 |
| 20110189960 | Estimating Whether A Wireless Terminal Is Indoors Using Pattern Classification - A method and apparatus for estimating whether or not a wireless terminal is indoors are disclosed. The illustrative embodiment employs a pattern classifier that is trained on a plurality of input/output mappings, where each mapping corresponds to a respective location, the output of the mapping is a Boolean value that indicates whether the location is indoors, and the input of the mapping is based on empirical and predicted signal data for the location. In accordance with the illustrative embodiment, a computer-executable program is generated based on the trained pattern classifier. The computer-executable program estimates whether or not a wireless terminal is indoors based on empirical data reported by the terminal, and on a location estimate for the terminal that might be crude or inaccurate (e.g., based on Cell Identifier [Cell-ID], GPS, etc.). | 08-04-2011 |
