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.

Claims

wherein each of the remote electrical tilt units is configured to;

receive permission configuration information sent by a first base station through a group of AISG ports of the remote control unit; and

configure, according to the permission configuration information, management permission of the first base station on the remote electrical tilt unit.

2. The remote electrical tilt antenna according to claim 1, wherein:

the permission configuration information comprises control permission configuration information; and

each remote electrical unit is configured to;

receive control permission configuration information sent by the first base station through the group of AISG ports of the control unit, and

notify the first base station of a control permission conflict when the control permission on the remote electrical tilt unit is allocated to a second base station, or allocate the control permission on the remote electrical tilt unit to the first base station when the control permission on the remote electrical tilt unit is not allocated.

3. The remote electrical tilt antenna according to claim 1, wherein:

the permission configuration information comprises query permission configuration information; and

each remote electrical tilt unit is configured to;

receive query permission configuration information sent by the first base station through the group of AISG ports of the control unit, and
