Abstract: A method includes: obtaining user equipment distribution information of a beam domain, where there are at least two beam domains, and the beam domain is a vertical area in a physically vertical dimension of a cell coverage area; determining information about a concentrated beam domain based on the user equipment distribution information, where the concentrated beam domain is a beam domain in which a quantity of covered user equipments exceeds a quantity threshold; and compared with information about a historical concentrated beam domain, if the information about the concentrated beam domain satisfies a preset condition, adjusting a broadcast beam domain based on the information about the concentrated beam domain, so that a main lobe direction of the broadcast beam domain is adjusted to a beam domain corresponding to the concentrated beam domain.
