MAIN POWER AREA ESTIMATION DEVICE AND MAIN POWER AREA ESTIMATION METHOD

摘要

A GPS position information acquisition unit (601) and a delay position information acquisition unit (602) acquire delay information, PRACH-PD position information and GPS position information. A main power area estimation unit (613) calculates the distribution of mobile devices (100) on the basis of the delay information, PRACH-PD position information, or GPS position information. Furthermore, the main power area estimation unit (613) estimates, on the basis of the calculated distribution of mobile devices (100) and the positions of antennas (201), the radius of a main power area wherein sectors to be estimated constitute the main power.
