Abstract
A synchronization module is associated with a network node of a communication network which comprises at least one Synchronization Master entity. The synchronization module has knowledge of a plurality of Synchronization Master references. Endpoints of paths of the plurality of Synchronization Master references are obtained. Each of the paths extends between one Synchronization Master Entity and the first or the second access network node. The paths are obtained from a synchronization report module based on the obtained endpoints. For each of the Synchronization Master references, a first path and a second path of the obtained paths are selected. A time synchronization inaccuracy value between the first and the second access network node is calculated based on the selected paths. A Synchronization Master reference is selected based on the calculated time synchronization inaccuracy values, and the first and the second access network node are notified which Synchronization Master reference was selected.
