Method And Apparatus For Performing A Time Synchronization Of A Base Site

View page
US Patent:
61854298, Feb 6, 2001
Filed:
Jul 31, 1998
Appl. No.:
9/127484
Inventors:
James K. Gehrke - Lake in the Hills IL
Timothy J. Groch - South Elgin IL
Steven P. Shipton - Palatine IL
Mark G. Spiotta - Wheaton IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
H04B 100
US Classification:
455502
Abstract:
An unsynchronized base site (104) transmits a time synchronization request to a communication unit (110). A time synchronization error, or a timing offset, for the unsynchronized base site (104) is then determined and transmitted back to the unsynchronized base site (104) to enable the unsynchronized base site to synchronize itself. The time synchronization error is determined for the unsynchronized base site (104) based on the time difference of arrival of the signals received by the communication unit (110) from the base site (104) and at least one synchronized base site (101), the location of the communication unit (110), the location of the base site (104), and the location of the at least one synchronized base site (101).

US Patent:
60913576, Jul 18, 2000
Filed:
Dec 28, 1998
Appl. No.:
9/221058
Inventors:
Dominic Lazara - Chicago IL
Jeffrey J. Blanchette - Palatine IL
Frank W. Korinek - Carol Stream IL
Timothy J. Groch - Palatine IL
Assignee:
Motorola, Inc. - Schaumburg IL
International Classification:
G01S 502
H04B 7185
US Classification:
34235703
Abstract:
The present invention addresses the need for an apparatus and method of determining the reliability of a first signal (e. g. , 116) received by a given base site (e. g. , 126) without requiring the reception of additional signals (e. g. , 110 and 112) by the given base site (126). The present invention provides both a method and apparatus in which another base site (e. g. , 122) receives the additional signals (110 and 112) required to determine the reliability of the first signal (116). Upon determining that the first signal (116) is unreliable, the other base site (122) notifies the given base site (126) that the first signal (116) is unreliable.
