摘要： An interference control method and apparatus in a self-organizing system are provided. The method includes the following steps: interference information is received at an access node from at least two other access nodes, wherein the other access nodes serve communication devices interfered by the access node; then the interference information is evaluated at the access node to determine at least one action that could be taken because of the interference; information about the determined at least one action is communicated to at least one of the at least two other access nodes, and the recipient node is operated accordingly.
