Patent ID: 10756832

Abstract:
In the present invention, in order to predict discontinuous wireless quality changes without using wireless terminal position information in a cellular type wireless communication system, a wireless quality prediction device is provided with: a measurement information acquisition means for acquiring wireless quality measurement information measured by a wireless terminal that moves within a wireless communication system having at least two wireless cells; a wireless quality transition pattern construction means for using the measurement information to construct, as a wireless quality transition pattern, a time-series data pattern of wireless quality associated with the passage of time; and a wireless quality prediction means for acquiring from the wireless quality transition pattern construction means a wireless quality transition pattern having a high degree of similarity to the measurement information, in regards to the wireless quality measurement information acquired from a wireless terminal for which a prediction is to be made, and for using the acquired wireless quality transition pattern to predict that future wireless quality in respect to the wireless terminal for which a prediction is to be made, or a wireless cell in which the wireless terminal for which a prediction is to be made is located, will change in the future.
