摘要： PROBLEM TO BE SOLVED: To provide a method of using a non-GPS-derived technology to estimate a location of an Assisted-GPS-enabled wireless terminal for the purpose of generating location-specific assistance data for the wireless terminal. SOLUTION: The wireless terminal uses the assistance data to acquire and process one or a plurality of GPS signals and derive information that is probative of the location of the wireless terminal. The GPS-derived location information is then combined with a non-GPS-derived location to form the estimate of the location of the wireless terminal that is more favorable than the case that it can be derived from either the GPS or non-GPS alone. This combination of GPS-derived and non-GPS technologies is particularly useful when the wireless terminal can only acquire one or two GPS signals because it is impossible to determine the location of the wireless terminal by only two GPS signals.

摘要： PROBLEM TO BE SOLVED: To provide a technique for predicting the position of a radio terminal, at an unknown location in a geographical region. SOLUTION: The technique for predicting the position of the radio terminal is based on the features of electromagnetic (radio) signal depending on topography, receiver, the location of transmitter, and other factors. Under the presumption that the radio terminal is received strongly at a first location and weak at a second location, for example; when the radio terminal located at an unknown location receives a weak signal from a specified radio (base) station, the possibility is high that the radio terminal is located not at the first location but at the second position.

SOLUTION: The technique is based on the recognition that there are traits of electromagnetic (radio) signals that is dependent on topography, the receiver, the location of the transmitter, and other factors. For example, if a signal from a particular radio (base) station is known to be received strongly at a first location and weakly at a second location and a given wireless terminal at an unknown location is receiving the signal from the radio (base) station weakly, it is more likely that the wireless terminal is at the second location than at the first location.

摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus for estimating whether a wireless terminal is indoors. SOLUTION: 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.).

摘要： PROBLEM TO BE SOLVED: To provide a method for predicting the positions of wireless terminals through the use of a non-GPS extraction technique for generating auxiliary data for specifying the positions of the wireless terminals adapted to assisted GPS. SOLUTION: A wireless terminal acquires and processes one or a plurality of GPS signals through the use of auxiliary data and extracts information proving the position of the wireless terminal. Subsequently, GPS extraction position information is combined with a non-GPS extraction position to form a prediction value of the position of the wireless terminal. This combination of a GPS extraction technique and a GPS extraction technique is especially useful when the wireless terminal can acquire only one or two GPS signals, since it is not possible to determine the position of the wireless terminal only by two GPS signals.
