SYSTEM AND METHOD FOR DETERMINING LOCATION USING Wireless Broadband (WIBRO) SIGNAL

摘要

1. positioning system using a wireless broadband (WiBro) signal containing! the main base station for providing information about neighboring base stations and transmitting the result of scanning neighbor base stations; ! terminal for receiving the information about the neighboring base stations, scanning the neighboring base stations in response to a request for position determination, and transmitting the result of scanning neighboring base stations to the main base station and! positioning the object (PDE) to determine the location of the terminal using relative delay information between the main base station and the neighboring base stations, which is included in the result of scanning neighbor base stations from the primary base station information and base station location. ! 2. The positioning system of claim 1, which is provided with at least two pieces of relative delay information. ! 3. The positioning system according to claim 1, wherein the PDE determines the position of the terminal using the distance difference between the terminal and neighbor base stations obtained using the relative delay information and base station location information. ! 4. The positioning system according to claim 1, wherein the PDE stores information of location of base stations, base station IDs corresponding information. ! 5. The positioning system according to claim 3, wherein the PDE extracts the relative delay information and base station ID information from the result of scanning neighboring base stations. ! 6. The system defined
