The present invention relates to an apparatus and method for pilot signal generation, and a system and method for measuring a position of a mobile station using a pilot signal generation apparatus. More particularly, the present invention relates to a mobile station by measuring the position of the mobile station in response to a location request received from the mobile station. The present invention relates to a pilot signal generation device and method for providing location information to a mobile station, and a location measurement system and method for a mobile station using the pilot signal generation device.

The development of high-speed wireless communication to IMT2000 and universal mobile telecommunication system (UMTS), which is being carried out at home and abroad, foreshadows the growth of data communication using wireless networks. In particular, a location-based data service providing a user location-based service among the services that can be provided using a wireless communication network is emerging as a core service.

In order to know the distance between the base station and the mobile station, the propagation time of the signal is calculated by the signal correlator.

In the case of time division multiple access (TDMA) and code division multiple access (CDMA), both of these propagation times are measurable. TDMA can observe time lag because the time at which the signal is sent varies slightly depending on how far the mobile station is to the base station.

The dummy pilot pseudo noise signal generated by each of the pilot signal generators 410-1 and 410-2 should be different from the pilot pseudo noise signal generated by the base station 420 and another base station adjacent to the base station 420. In addition, each of the pilot signal generators 410-1 and 410-2 receives a response signal for the dummy pilot pseudo noise signal from the mobile station 160, and receives a plurality of first parallax information from each of the received response signals. Create Each of the generated first parallax information is provided to the position measuring device 430.

The response signal includes information on the time at which the mobile station 160 receiving the dummy pilot pseudo noise signal transmits the response signal to the dummy pilot pseudo noise signal. Therefore, each of the pilot signal generating apparatuses 410-1 and 410-2 uses the transmission time included in the response signal corresponding to the dummy pilot signal transmitted by the pilot signal generator 410-1 and 410-2, and the reception time of the response signal.

The base station 420 provides a communication service to the mobile station 160, and provides a reference time to the pilot signal generators 410-1 and 410-2. In addition, the base station 420 receives the response signal for the pilot pseudo noise signal transmitted from the mobile station 160 to generate the second parallax information. The second parallax information generated by the base station 420 is provided to the position measuring device 430. The configuration of the response signal to the pilot pseudo-noise signal transmitted by the base station 420 and the second parallax information generation process of the base station 420 are dummy pilot pseudo noises transmitted by the pilot signal generators 410-1 and 410-2. Since the structure of the response signal to the signal and the first disparity information generating process of the pilot signal generating apparatuses 410-1 and 410-2 are similar, detailed description thereof will be omitted.

The position measuring apparatus 430 may receive RTP information, that is, each of the first parallax information provided by the respective pilot signal generators 410-1 and 410-2 and the base station 420. The position of the mobile station 160 is measured based on the second parallax information provided by.

The position measuring device 430 has a distance calculator 432 and a positioning unit 434.

The distance (R ₁ and R 2) between ₂ ) is calculated. The distance calculator 432 also calculates the distance R ₃ between the mobile station 160 and the base station 420 based on the second parallax information.

The positioning unit 434 focuses on the point where the respective pilot signal generators 410-1 and 410-2 are installed, and the mobile station 160 and the respective pilot signal generators 410-1 and 410-2. The circle whose radius R ₁ and R ₂ is the radius and the point where the base station 420 is installed, and the circle whose radius R ₃ is the distance between the mobile station 160 and the base station 420 The point of intersection is determined as the location of the mobile station 160.

In FIG. 5, a concept in which the position measuring device 430 determines the position of the mobile station 160 using parallax information is schematically illustrated. In order to measure the position of the mobile station 160 in the above-described manner, the mobile station 160, the pilot signal generators 410-1 and 410-2, and the base station 420 must all keep accurate synchronization.

When the mobile station 160 is notified that it is located in the handoff area, the mobile station 160 does not recognize the dummy pilot pseudo noise signal transmitted by the pilot signal generators 410-1 and 410-2, and thus the mobile station ( 160 does not transmit a response signal to the dummy pilot pseudo noise signal.

In this case, the position measuring device 430 locates the mobile station 160 based on the signal of the mobile station 160 detected by the base stations 420, 450, and 460 having a communication link established with the mobile station 160.

When receiving the location request from the mobile station 160 (S705), the base station controller 440 checks whether the mobile station 160 is located in the handoff area (S710). If it is determined that the mobile station 160 is not located in the handoff area, the process proceeds to step S715.

The mobile station 160 transmits the dummy pilot pseudo noise signal received from the pilot signal generators 410-1 and 410-2 and respective response signals for the pilot pseudo noise signal received from the base station 420 (S715). .
