Abstract
A system and method for estimating a location of a wireless device receiving signals from a plurality of nodes of a communication system. A first value may be determined based on a network timing characteristic for one of the nodes, and a second value may be determined based on a network measurement report characteristic. An observed time difference of arrival ('OTDOA') hyperbola may then be calculated based on the first and second values, and a location of the wireless device estimated as a function of the OTDOA hyperbola.
