    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.

    Abstract: A radio communication system, a radio station, a network operation management apparatus, and a network healing method are provided that can suppress system performance degradation caused when a failure occurs in a radio base station, a network apparatus, or the like. In a radio communication system which includes multiple radio stations (10, 20) and a network operation management apparatus (30) managing the radio stations and in which network optimization is performed, at least one of a first radio station (10) in which a failure occurs, a second radio station (20) different from the first ration station, and the network operation management apparatus (30) sends alarm information regarding the failure.
