A method (200) for facilitating network identification is provided. The method comprises, at an access node of a first network: detecting (S210) a physical-layer-related identity of each of one or more neighboring access nodes; decoding (S220), for each of the one or more neighboring access nodes, a network identity of the neighboring access node; for each of the one or more neighboring access nodes: determining (S230) whether the neighboring access node belongs to the first network or a different network; and determining (S230) an identity group in which the detected physical-layer-related identity of the neighboring access node is included; and selecting (S240), as a physical-layer-related identity of the access node, a physical-layer-related identity from an identity group other than any identity group in which a physical-layer-related identity of a neighboring access node belonging to a different network is included.
