Patent ID: 8855623

Claim:
A radio wave state measurement system comprising: a storage unit configured to store a time when a radio parameter of a base station is updated, before the radio parameter is actually updated; and an instruction unit configured to instruct a mobile terminal, which is in communication with the base station, to measure a radio wave state corresponding to the base station at a timing according to the stored time, wherein the instruction unit is configured to limit an area in which the measurement of the radio wave state is performed by referring to an estimated radio wave state, which is estimate as respective radio wave state that occurs either before or after the radio parameter is updated, wherein the instruction unit is configured to compare the estimated radio wave state before the radio parameter is updated to the estimated radio wave state after the radio para is updated, wherein the instruction unit is configured to extract an area in which the estimated radio wave state after the radio parameter is updated deteriorates more than a predetermined degree as compared to the estimated radio wave state before the radio parameter is updated, as a radio wave state deteriorated area, and wherein the instruction unit is configured to make the mobile terminal located inside the radio wave state deteriorated area perform the measurement of the radio wave state.
