RADIO WAVE OBSERVATION SYSTEM, CENTRAL STATION DEVICE, AND RADIO WAVE OBSERVATION METHOD

摘要

[Problem] To observe radio wave usage circumstances over a wide area and convert same into a database, at an achievable cost. [Solution] A radio wave observation system comprises: a plurality of wireless networks, further respectively comprising multiple terminal stations (2) and a plurality of base stations (3), which carry out wireless communication between the terminal stations and the base stations; and a central station device (4) which is connected to these base stations. Each of the terminal stations (2) further comprises an observation device (2a) which carries out radio wave observation and returns the results of the observation to the central station device in response to an instruction from the central station device. The central station device (4) further comprises: a storage means (5), further comprising a radio wave circumstance database (5a) which records the radio wave circumstances for each observation point; a terminal search function (6) which identifies, for each measurement point, the terminal station which is associated with one of the plurality of wireless networks, the present location whereof being the closest to the measurement point; and a radio wave circumstance collecting function (7) which instructs the identified terminal station to carry out the radio wave observation, and records the returned results of the observation in the radio wave circumstance database.

1. A radio wave observation system comprising:
a plurality of radio networks each of which includes a plurality of base stations and a number of terminal stations corresponding to each of the plurality of base stations and carries out radio communication between each of the terminal stations and the base station; and a central station device that is connected to the base stations, wherein each of the terminal stations includes an observation device that carries out radio wave observation when an instruction is issued by the central station device, and that responds to the central station device with a result of the observation, and wherein the central station device includes a storage unit that includes a radio wave state database in which a radio wave state in each measurement spot is recorded, a terminal search function for identifying, for each measurement spot, a terminal station that has a current position closest to the measurement spot and is included in any one of the plurality of radio networks, and a radio wave state collection function for instructing the identified terminal station to carry out radio wave observation and recording, in the radio wave state database, a result of the observation returned in response to the instruction.
