Kind Code:
A1
Abstract:
Provided is a radio base station that can maintain its internal clock with high precision even if an external temporal information notifying server, such as NTP server or the like, malfunctions. A radio base station (1-1), which wirelessly communicates with mobile terminals, is connected to a plurality of temporal information notifying servers (1-2, 1-3, 1-4). The radio base station (1-1) selects one of a plurality of pieces of temporal information notified by the respective ones of the plurality of temporal information notifying servers (1-2, 1-3, 1-4) and corrects, based on the selected temporal information, its internal clock. In this way, the internal clock of the radio base station can be maintained with high precision.
