    摘要: An apparatus and method for location estimation in a portable terminal are provided. An operation of the portable terminal includes, if a location estimation function is activated, determining whether a reference location corresponding to a cell IDentifier (ID) of a currently connected cell is prestored, determining a search frequency range of a Global Positioning System (GPS) signal using the stored reference location, and estimating a location of the portable terminal using the GPS signal detected in the search frequency range.

    摘要: An apparatus and method for sharing assistance data between an Assisted Global Positioning System (A-GPS) terminal and a Global Positioning System (GPS) terminal are provided. The method includes establishing a connection with an A-GPS terminal, transmitting an assistance data request message to the A-GPS terminal, receiving an assistance data response message including assistance data from the A-GPS terminal, and performing position determination by using the assistance data and GPS position information received from a GPS artificial satellite. Accordingly, position determination can be achieved faster.
