The invention discloses a method and an apparatus controlling up load. The method comprises receiving searching capacity of each antenna of a receiver. The search energy of each antenna respectively represents capacity sum of all client devices singals searched by the antenna; according to the search capacity of each antenna, a correction factor of load information is determined; the load information comprises broadband reception total power and/or a load factor; according to the correction factor of the load information, corrected load information is determined, so up load of a small area serviced by the receiver can be controlled. With the method and an apparatus controlling up load and search capacity of each antenna via the receiver as well as the searching capacity of each antenna, correction factor of the load information can be determined, so the corrected load information can accurately reflect a current load condition.
