Claim Text:
1. A method comprising: receiving an indication from a node of a communication system in which communications occur via a plurality of nodes each providing a stratum for syncronisation, wherein the indication comprises one of the order number of the stratum if the stratum of the node transmitting the indication is in a predefined set of stratums, and a uniform indication if the stratum of the node is not in the predefined set of stratums; determining whether or not the stratum of the node is included in a predefined set of stratums in which case synchronisation with the node would be based at least in part on the order of the stratum; and in response to determining that the stratum is not included in the predefined set of stratums, synchronizing with the node differently from nodes with stratums that are determined to be included in the predefined set of stratums without taking the order of the stratum into account.
