The present disclosure relates to a method, performed in a network node of a first network, for designating one or more cells of a second network as neighbouring cells to the first network. The method comprises selecting a set of carriers employed in the second network and transmitting information for the selected set of carriers to a wireless device served by the first network. Measurement reports are received for respective carriers from the wireless device. The network node determines neighbour cell relations between the first network and one or more cells of the second network based on the received measurement reports.

The invention relates to a method in a communication node () for commonly managing resources in a radio access network between different network access technologies, which communication node () is comprised in a radio access network of a radio communications network. The communication node receives () from a first local resource manager () of a first network access technology, a first report of information regarding resources needed per service associated with the first network access technology, which service is associated with a first local service priority. The communication node () then receives () from a second local resource manager () of a second network access technology, a second report of information regarding resources needed per service associated with the second network access technology. The service is associated with a second local service priority. The communication node ranks the service priority in the first report in relation to the service priority in the second report. The communication node generates an allocation scheme of resources, which allocation scheme allocates resources to at least one of the first or second local resource managers () based on the ranking of the service priorities.
