Embodiment approach

[0036] An exemplary embodiment: the antenna end calculates the number of turns and the direction that the motor needs to rotate according to the angle information in the adjustment command and the functional relationship between the horizontal azimuth angle and the number of turns of the motor, and controls the rotation according to the number of turns and the direction of rotation The motor turns.

[0037] For example, the functional relationship between the horizontal azimuth Φ and the number of rotations n of the motor is Φ=f(n), and the adjustment command issued by the network management system includes Φ, and the antenna end can know the number of rotations and direction of the motor rotation according to the functional relationship.

[0038] Under the premise that the base station equipment network management does not perform any new development work, the above method can make the physical RAS equipment appear as a logical RET equipment through the logical RET identifier,...

Abstract

The invention discloses a method, device and system for remotely adjusting an antenna, and relates to the technical field of wireless communication. The method includes the following steps: an antenna end receives an angle adjustment command issued by a network management end, wherein the angle adjustment command includes angle information and logic remote electrical tilt (RET) identifier of an adjustment object; the logic RET identifier satisfies an RET identification mode and contains a differentiating position of RET equipment and remote azimuth steering (RAS) equipment; the antenna end judges that the adjustment object belongs to the RET equipment or the RAS equipment according to the differentiating position of the logic RET identifier in the adjustment command; if the adjustment object belongs to the RET equipment, the electrical tilt is adjusted according to the angle information in the adjustment command; and if the adjustment object belongs to the RAS equipment, a horizontal azimuth is adjusted according to the angle information in the adjustment command. According to the method for remotely adjusting the antenna, on the premise that no new development work of network management of base station equipment is carried out at all, and based on an RET protocol, remote adjustment of the electrical tilt and horizontal azimuth of the antenna is realized. A great deal of software development work of network management of the base station equipment is avoided, and expenses and risks brought by a system upgrade are also greatly reduced.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a method, device and system for remotely adjusting an antenna. Background technique [0002] Due to the many advantages of remote electronically adjustable antennas, it has become the first choice of most operators during the 4G network construction phase. During network operation and maintenance, network optimization engineers can remotely adjust the electrical downtilt angle of antennas through the network management system to improve cell coverage performance, eliminating the need for manual on-site adjustments and improving optimization efficiency. However, at present, only the electrical downtilt is adjusted, and in some special scenarios, such as tidal effects and interference coordination scenarios, remote horizontal azimuth adjustments are also required. Therefore, in practical applications, the adjustment of the two dimensions of electrical downti...
