PURPOSE: A method for measuring a position of a UE(User Equipment) using the increase of a burst power and a system therefor are provided to measure the position of the UE using an AOA(Arrival Of Angle) and an RTT(Round Trip Time) on the basis of light weight and simplification of the UE. CONSTITUTION: An SRNC(Servicing Radio Network Controller)(100) informs a scrambling code of a connected corresponding UE(300) to node-Bs(200) in the circumference of the UE(300), and the node-Bs(200) measure AOAs and RTTs transmitted from the UE(300)(S3). The node-Bs(200) requests signal transmission to an upward link(S4), and the UE(300) transmits an upward link signal(S5). The AOAs and the RTTs measured from the upward link transmission signal of the UE(300) by two or more node-Bs(200) are transmitted to a PCF(Position Calculation Function) block of the SRNC(100)(S6). The node-Bs(200) requests that a signal is retransmitted by more increased power to the UE(300)(S7). The UE(300) retransmits the upward link signal by an increased power(S8). |
