Patent ID: 8112096

Claim:
A method for estimating a location of an unknown Node B in a wireless communication system having a plurality of other nodes and a plurality of location measurement units (“LMU”), the method comprising: (a) determining a first value based on a network measurement report characteristic; (b) determining a second value based on a first network timing characteristic one of the plural LMUs; (c) determining a third value based on a second network timing characteristic; (d) determining a fourth value based on a third network timing characteristic; (e) calculating an observed time difference of arrival (“OTDOA”) hyperbola based on at least one of said first, second, third, or fourth values; and (f) estimating a location of said unknown Node B as a function of said OTDOA hyperbola, wherein said network measurement report characteristic is a time offset between a first node and said unknown Node B, and wherein said first network timing characteristic is a time offset between a first node and said unknown Node B measured by a first LMU in said plurality of LMUs.
