Abstract

Embodiments of the present invention provide a remote electrical tilt unit, a base station, and a method for managing a remote electrical tilt antenna. The method includes: receiving, by the remote electrical tilt unit, permission configuration information sent by a first base station through a group of AISG ports of the remote control unit; configuring management permission of the first base station on the remote electrical tilt unit according to the permission configuration information, where the management permission includes at least control permission and query permission, and control permission on the remote electrical tilt unit can be allocated to only one base station. In this way, multiple base stations jointly manage a remote electrical tilt unit in a remote electrical tilt antenna, and a problem that it is difficult to locate and troubleshoot a fault when configuration of the remote electrical tilt unit is incorrect is resolved.
