Abstract:
1. A method for handling of an overload by network nodes in a communications network, wherein said communications network is based upon a tree topology providing several levels of nodes in said communications network, said method comprising: providing of information about said overload by a node of a level of said communications network to a set of network nodes of a lower level, if an overload node, said overload node being a node with regard to which said overload has occurred, is said network node or a network node of an upper level to which said network node is connected; wherein each network node comprised in said set of network nodes is connected to said network node; wherein network nodes of a first level and a second level arranged below the first level are connected if they are either connected directly or connected through at least one further network node being located in at least one level between the first level and the second level in the communications network, wherein said information comprises an indication of said overload node, and wherein said set of network nodes comprises a relay node wirelessly connected to a base station of a radio access network.
