A base station is disclosed. The base station includes several radio devices and a core network device. The core network device is connected to the several radio devices and is configured to determine a first user location data corresponding to a user device according to a user uplink transmission data and several user location data, and to determine whether to allow the user device to perform a data uplink transmission operation or not according to the first user location data. The user uplink transmission data is uplink transmitted by the user device, and the several user location data are establish according to the several radio devices and several user locations. The several user location data include the first user location data.

Base station and data uplink transmission abnormal detection method

A threat detection apparatus and a threat detection method thereof for a wireless communication system are provided. The threat detection apparatus receives an observed time difference of arrival (OTDOA) message for positioning a user equipment (UE) from a serving base station (BS), and determines that the UE connects to a false BS when the identity of the serving BS is not on the identity list. If the identity of the serving BS is on the identity list, the threat detection apparatus calculates a first distance according to the measurement report message transmitted from the UE, and calculates a second distance between the UE and the serving BS according to the OTDOA message. When the difference between the first distance and the second distance is larger than a threshold, the threat detection apparatus determines that the UE connects to the false BS.
