Abstract

The present invention refers to handling of an overload in a communications network and to handling of handovers occurring after the handling of handovers in the communications net work, wherein said communications network is based upon a tree topology providing several levels of nodes in said communications network. According to the present invention, in formation about an overload is provided through several levels of nodes in communications network, starting from the node, with regard to which said overload has occurred, and ending with nodes being located in levels arranged upside the level, in which the overload occurred, and being connected directly or indirectly with the node, with regard to which said overload has occurred. When handling a handover from a cell in a node, which is affected by the overload, the handover will be allowed only if the cell comprises at least one node, which is also affected by the overload.
