Abstract

A time stamp distribution system and corresponding method for a cellular telecommunication network (10), wherein a time distributing master node (20) receives a unique time stamp value from a reliable time source (24), such as a GPS terminal device, and forwards this time stamp value to a plurality of time slave nodes (22a-22c) of the cellular telecommunication system, through the signalling network (14) of the cellular telecommunication network. Upon receipt of the time stamp value, the time slaves nodes can synchronise their own internal clocks (23a-23c), so that time drifts between co-operating cellular nodes are avoided. The time synchronisation sequence can be either manually or automatically initiated from both the master node side and the slave node side.
