Methods and systems of adjusting antenna electrical tilt

摘要

There is provided a computer-implemented method for selecting an electrical tilt angle for at least one cellular antenna comprising: receiving at least one parameter indicative of mobile client resource use associated with at least one cellular antenna, the at least one cellular antenna being part of a plurality of antennas arranged in at least one cluster as part of a cellular network; and iteratively adjusting an electrical tilt angle of the at least one antenna so that the at least one parameter indicative of client resource use is maintained within at least one predefined threshold, thereby providing users of the mobile clients of the at least one cellular antenna with at least a level of service within the at least one predefined threshold.

1. A computer-implemented method of selecting an electrical tilt angle for at least one antenna, the method being carried out by a tilt angle calculation unit programmed to carry out the steps of the method, which comprise: receiving at least one parameter indicative of mobile client resource use associated with at least one cellular antenna, the at least one cellular antenna being part of a plurality of antennas arranged in at least one cluster as part of a cellular network; selecting a target coverage parameter for the at least one antenna according to the at least one parameter indicative of client resource use; calculating a coverage cost for the at least one antenna using an initial electrical tilt angle; iteratively adjusting an electrical tilt angle of the at least one antenna so that the at least one parameter indicative of client resource use is maintained within at least one predefined threshold, thereby providing users of the mobile clients of the at least one cellular antenna with at least a level of service within the at least one predefined threshold and wherein iteratively adjusting further comprises iteratively adjusting the electrical tilt angle according to the calculated coverage cost for the selected tilt angle relative to the target coverage cost parameter.
