AGPS system using a public radio paging network and a terminal position measurement method using the system

摘要

An assisted global positioning system (AGPS) system capable of determining a position of a terminal more quickly and accurately by transceiving AGPS data utilizing a public radio paging network, which can transmit a large quantity of data at a very high speed. The present invention provides a mobile terminal with AGPS data through a public radio paging network, and the mobile terminal obtains a GPS signal more quickly by means of the AGPS data provided through the public radio paging network. Accordingly, the present invention reduces the time required for determining a terminal position using the GPS signal.
