`ABSTRACT
`(57)
`A hybridWireless location system and method is disclosed for
`locating mobile stations (MSs). Multiple Wireless location
`techniques (FOMs) are provided for MS location. One or
`more FOMs can be activated in various combinations (seri
`ally or parallelly) for outputting one or more MS location
`estimates With signal protocols, e.g., CDMA, TDMA, or
`GSM. Resulting location estimates may be for, e.g.: 911
`emergency calls, tracking, navigation, people and animal
`location, and] or applications for con?nement to andlor exclu
`sion from geographical areas. System components may be
`distributed on a network (e.g., the Internet). FOMs may be
`based on one or more of: TOA, TDOA, AOA, signal pattern
`recognitionl?ngerprinting, statistical analysis, base station
`coverage, GPS signals received at the MS, andlor input from
`mobile stations. Location estimates are enhanced by adjust
`ing MS estimates (and/or con?dences therefor) according to:
`a past performance of the FOM providing such estimates,
`and/or MS geolocation or velocity constraints.
