  • Publication number: 20140211605
    Abstract: The present invention discloses a method and an apparatus for coordinating cell outage compensation and capacity and coverage optimization, and belongs to the communications field. In the present invention, a cell to be coordinated is determined, where the cell is a cell that needs coordination of a COC action and a CCO action; priorities of the COC action and the CCO action are compared, and a high-priority action and a low-priority action are determined in the COC action and the CCO action; and for the cell to be coordinated, the high-priority action continues to be performed, and the low-priority action is stopped from being performed. This effectively solves a problem of a conflict generated when the COC action and the CCO action are performed for the same cell, and ensures normal execution of a network optimization action with a relatively high priority.
