1. A position measuring system using a Wireless Broadband (WiBro) signal, comprising:
- a main base station for providing information about neighboring base stations and transmitting a neighboring base station scan result;
a terminal for receiving the information about the neighboring base stations, scanning the neighboring base stations in response to a position measurement request, and transmitting the neighboring base station scan result to the main base station; and
a Position Determination Entity (PDE) for measuring the position of the terminal using relative delay information between the main base station and the neighboring base stations, which is included in the neighboring base station scan result from the main base station, and base station position information.

Abstract
Provided is a position measuring system and method using a Wireless Broadband (WiBro) signal. The position measuring system measures the position of a terminal using relative delay information that is a parameter of the WiBro signal, used for a hand-over. Since the position of a terminal is measured using a parameter for a hand-over, additional data measurement is not required for the position measurement. Furthermore, efficiency in the use of a parameter of a WiBro system can be improved by using a parameter used only in the hand-over for position measurement.
