摘要:
A method and network node for backhaul link failure recovery are disclosed. A network node is configured to attempt to find an alternative backhaul link to replace the failed backhaul link. If the attempt to find an alternative backhaul link fails, then the network node communicates a first indication of an existence of the failure to the first child network node one level below the network node affected by the failure and causes the first child network node to find another network node to serve as a new parent network node. If the first child network node finds another node to serve as the new parent network node then the network node is configured to serve as a second child network node of the first child network node so that the first child network node serves as a parent of the network node.
