A method for adjusting a broadcast beam domain, comprising: obtaining user equipment distribution information of a beam domain, wherein 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, and the user equipment distribution information is a distribution situation of user equipments in a coverage area of each beam domain; determining information about a concentrated beam domain based on the user equipment distribution information, wherein 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 the 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, wherein the determining information about the concentrated beam domain based on the user equipment distribution information comprises: obtaining, based on the user equipment distribution information, each quantity of user equipments covered by each beam domain; and if the quantity of user equipments exceeds the quantity threshold, determining a beam domain corresponding to the quantity of user equipments as the concentrated beam domain, and recording the information about the concentrated beam domain, wherein there is at least one concentrated beam domain, and wherein before the adjusting the broadcast beam domain based on the information about the concentrated beam domain, the method further comprises: obtaining the information about the historical concentrated beam domain, wherein the historical concentrated beam domain is a beam domain corresponding to the broadcast beam domain used when a broadcast beam was transmitted last time; if the historical concentrated beam domain and the concentrated beam domain reach a preset area isolation, determining that compared with the information about the historical concentrated beam domain, the information about the concentrated beam domain satisfies the preset condition. obtaining user equipment distribution information of a beam domain, wherein 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, and the user equipment distribution information is a distribution situation of user equipments in a coverage area of each beam domain;
