Claim:
1. A non-transitory computer readable storage medium containing instructions, which when executed by a processor in a network node of a communication network that includes at least one synchronisation master entity, causes the network node to perform operations comprising: obtaining endpoints of paths of a plurality of synchronisation master references, wherein respective paths extend between one of the at least one synchronisation master entity and a first access network node or a second access network node; obtaining the paths based on the obtained endpoints; for respective synchronisation master references of the plurality of synchronisation master references: selecting a synchronisation master reference from the plurality of synchronisation master references based on the calculated time synchronisation inaccuracy values, for notifying the first access network node and the second access network node as to which synchronisation master reference of the plurality of synchronisation master references was selected.
