Abstract:
1. A method for use in a Wireless Location System (WLS) capable of locating a mobile transmitter and delivering location estimates to one or more location-based applications, wherein a location estimation process is performed according to one or more quality-of-service parameters, comprising the steps of: (a) assigning at least a first and a second set of predetermined quality-of-service parameters to a specific call class or mobile transmitter identity; (b) producing a first location estimate in a process whereby the collection of signal data and location calculation processing have been constrained by the first set of quality-of-service parameters; (c) delivering the first location estimate to at least one of the said one or more location-based applications; (d) producing a second location estimate with a process whereby the collection of signal data and location calculation processing have been constrained by the second set of quality-of-service parameters; and (e) delivering the second location estimate to at least one of the said one or more location-based applications.
