WIRELESS BASE STATION DEVICE, WIRELESS SYSTEM, AND FAILURE DETECTION METHOD |
摘要 |
A wireless base station device includes a broadcast signal transmission unit that transmits a broadcast signal to a cell; a measurement signal communication unit that transmits to a mobile terminal device existing in the cell a measurement instruction signal and receives a measurement report signal from the mobile terminal device; a failure detection processing unit that detects a failure of a first cell with respect to a transmission function from the wireless base station to the first cell according to whether a measurement report signal including a measurement report of a wireless quality for a second cell measured by a mobile terminal device existing in a coverage area of the first cell is received or not; and an alarm signal transmission unit that transmits an alarm signal to notify a failure monitoring device of an occurrence of the failure of the first cell. |

1. A wireless base station device, comprising:
a broadcast signal transmission unit configured to transmit a broadcast signal to a cell corresponding to the wireless base station device; a measurement signal communication unit configured to transmit to a mobile terminal device existing in the cell a measurement instruction signal for instructing to perform a measurement of a wireless quality of the broadcast signal transmitted by the broadcast signal transmission unit and to receive a measurement report signal for reporting the measurement of the wireless quality for the cell from the mobile terminal device; a failure detection processing unit configured to detect a failure of a first cell with respect to a transmission function from the wireless base station to the first cell in accordance with whether a measurement report signal including a measurement report of a wireless quality for a second cell measured by a mobile terminal device existing in a coverage area of the first cell is received or not when a measurement report of a wireless quality for the first cell is not included in the measurement report signal received by the measurement signal communication unit; and an alarm signal transmission unit configured to receive from the failure detection processing unit a notification of the first cell in which a failure is detected when the failure of the first cell is detected by the failure detection processing unit and to transmit an alarm signal to notify a failure monitoring device of an occurrence of the failure of the first cell. |
