A backhaul domain of the communication network is determined 400, and a request for a synchronisation reference is received 402 from the first access node, the request comprising, ID:s of the first and second access nodes. For each one of the first and second access nodes, a first and a second combination are determined 404 of a first and a second respective synchronisation reference and related synchronisation paths extending between synchronisation reference nodes of the synchronisation references and the access nodes. For each one of the first and second access nodes, the first or the second combination of synchronisation reference and related synchronisation path is selected 406 based on synchronisation requirements for the first and second access nodes, and the first path or the second path is requested to be set-up 408 according to the selected 406 combination. By providing functionality which works on the top of existing control of radio and transport domains, appropriate synchronisation references may be determined with a limited amount of information exchanged between the respective domains. |
