摘要:
A wireless location system/method is disclosed having one or more location centers for locating mobile units. Mobile unit location requests can utilize Internet communication between a network of location centers. A plurality of mobile unit locating technologies may be used, including those based on: TOA, TDOA, GPS, locations of other mobile units in proximity of the mobile unit being located, indoor wireless signal detection units; and reduced coverage base stations. Location determination strategies disclosed: adapting and calibrating system performance according to environmental and geographical changes, using location signal data for enhancing a database of predictive location data, heuristically evaluating mobile unit estimates related to terrain, mobile unit velocity and path, and adjusting mobile unit location estimations adaptively or statistically. The system/method is useful for emergency calls, tracking, routing, people and animal location, including applications for confinement to and exclusion from certain areas.

A wireless location system is disclosed having one or more location centers for locating mobile stations (MS) based on, e.g., WIFI, CDMA, AMPS, NAMPS, TDMA, GPRS, and GSM. MS location requests can be processed via, e.g., Internet communication between a network of location centers. A plurality of MS locating technologies may be used, including those based on: two-way TOA and TDOA; pattern recognition; distributed antennas; and reduced coverage base stations. The system includes strategies for: automatically adapting and calibrating system performance according to environmental and geographical changes; automatically capturing location signal data for enhancing a historical data base retaining predictive location signal data; evaluating MS locations according to heuristics and constraints related to, e.g., terrain, MS velocity and path; and adjusting likely MS locations adaptively and statistically. The system is useful for emergency calls, tracking, routing, people and animal location including applications for confinement to and exclusion from certain areas.

A location system and applications therefor is disclosed for wireless telecommunication infrastructures. The system is an end-to-end solution having one or more location systems for outputting requested locations of hand sets or mobile stations (MS) based on, e.g., CDMA, GSM, GPRS, TDMA or WIFI communication standards, for processing both local mobile station location requests and more global mobile station location requests via, e.g., Internet communication between a distributed network of location systems. The following applications may be enabled by the location system: 911 emergency calls, tracking, navigation, people and animal location including applications for confinement to and exclusion from certain areas, friend finder applications, and applications for allocating user desired resources based on the user's location.
摘要:
A wireless location system is disclosed that may be configured as a gateway for receiving a plurality of requests for locating mobile stations for, e.g., E911 requests, vehicle location or tracking. For each mobile station (MS) location request, the system: (a) activates one or more location estimators for locating the MS, (b) receives one or more MS location estimates from the estimators, and (c) transmits a resulting location estimate(s) to an identified destination. MS locations are determined using one or more locating technologies based on, e.g.: computed offsets from terrestrial base stations, satellite transmissions, indoor antennas, low range base stations, and/or signal fingerprinting. The system may: adapt with environmental changes, evaluate MS locations using heuristics/constraints, and/or adjust MS estimates for more reliable and accurate estimates. The system is useful for 911 emergencies, tracking, routing (e.g., to desired products/services), people and animal location including applications for confinement to and exclusion from certain areas.
摘要:
A location system is disclosed for commercial wireless telecommunication infrastructures. The system is an end-to-end solution having one or more location centers for outputting requested locations of commercially available handsets or mobile stations (MS) based on, e.g., CDMA, AMPS, NAMPS or TDMA communication standards, for processing both local MS location requests and more global MS location requests via, e.g., Internet communication between a distributed network of location centers. The system uses a plurality of MS locating technologies including those based on: (1) two-way TOA and TDOA; (2) pattern recognition; (3) distributed antenna provisioning; and (4) supplemental information from various types of very low cost non-infrastructure base stations for communicating via a typical commercial wireless base station infrastructure or a public telephone switching network. Accordingly, the traditional MS location difficulties, such as multipath, poor location accuracy and poor coverage are alleviated via such technologies in combination with strategies for: (a) automatically adapting and calibrating system performance according to environmental and geographical changes; (b) automatically capturing location signal data for continual enhancement of a self-maintaining historical data base retaining predictive location signal data; (c) evaluating MS locations according to both heuristics and constraints related to, e.g., terrain, MS velocity and MS path extrapolation from tracking and (d) adjusting likely MS locations adaptively and statistically so that the system becomes progressively more comprehensive and accurate. Further, the system can be modularly configured for use in location signaling environments ranging from urban, dense urban, suburban, rural, mountain to low traffic or isolated roadways. Accordingly, the system is useful for 911 emergency calls, tracking, routing, people and animal location including applications for confinement to and exclusion from certain areas.
