A method for activating a capacity station by using a beam, comprising: setting a set of beams to be transmitted for capacity stations in a dormant state according to positions and coverage areas of the capacity stations, in a case that it is detected that load of the coverage station is greater than a predetermined value, wherein the set of beams to be transmitted comprises at least one beam; transmitting the beams in the set of beams to be transmitted, and collecting load information corresponding to the beams in the set; determining capacity stations in the dormant state which need to be activated, according to the load information and a coverage relationship between the capacity stations in the dormant state and the set of beams to be transmitted; and activating the determined capacity stations in the dormant state which need to be activated by using the beams in the set of beams corresponding to the determined capacity stations; wherein the process of setting the set of beams to be transmitted for the capacity stations in the dormant state according to the positions and coverage areas of the capacity stations in the dormant state comprises: setting one corresponding beam for each capacity station in the dormant state, in a case that a quantity of the capacity stations in the dormant state is smaller than a first pre-set threshold; wherein the beams corresponding to the respective capacity stations in the dormant state form the set of beams to be transmitted, and each capacity station in the dormant state and the beam corresponding to the capacity station have a same coverage area. setting a set of beams to be transmitted for capacity stations in a dormant state according to positions and coverage areas of the capacity stations, in a case that it is detected that load of the coverage station is greater than a predetermined value, wherein the set of beams to be transmitted comprises at least one beam; transmitting the beams in the set of beams to be transmitted, and collecting load information corresponding to the beams in the set; determining capacity stations in the dormant state which need to be activated, according to the load information and a coverage relationship between the capacity stations in the dormant state and the set of beams to be transmitted; and activating the determined capacity stations in the dormant state which need to be activated by using the beams in the set of beams corresponding to the determined capacity stations; wherein the process of setting the set of beams to be transmitted for the capacity stations in the dormant state according to the positions and coverage areas of the capacity stations in the dormant state comprises: setting one corresponding beam for each capacity station in the dormant state, in a case that a quantity of the capacity stations in the dormant state is smaller than a first pre-set threshold; wherein the beams corresponding to the respective capacity stations in the dormant state form the set of beams to be transmitted, and each capacity station in the dormant state and the beam corresponding to the capacity station have a same coverage area. setting one corresponding beam for each capacity station in the dormant state, in a case that a quantity of the capacity stations in the dormant state is smaller than a first pre-set threshold; wherein the beams corresponding to the respective capacity stations in the dormant state form the set of beams to be transmitted, and each capacity station in the dormant state and the beam corresponding to the capacity station have a same coverage area.
