7. A method performed by a second network node for establishing a second feeder link towards an airborne or orbital communication node in non-terrestrial communications network to handle wireless devices being served by the airborne or orbital communication node, wherein a first network node is handling the wireless devices served by the airborne or orbital communication node over a first feeder link between the first network node and the airborne or orbital communication node, the method comprising:
determining that the wireless devices served by the airborne or orbital communication node are to be handled by the second network node over the second feeder link;
establishing the second feeder link towards the airborne or orbital communication node; and
transmitting, to the first network node, information indicating that the second network node has established the second feeder link towards the airborne or orbital communication node in order to handle the wireless devices being served by the airborne or orbital communication node,
wherein the information indicates a served cell(s) that the second network node is providing through the airborne or orbital communication node.
