Abstract
Synchronization is effected in a cellular telecommunications network ( ) between a master timing unit ( ) located at control node ( ) of the network and a slave timing unit (STU) located either at the control node or a controlled node, e.g., base station ( ), of the network. In accomplishing the synchronization, one of the master timing unit or the slave timing unit serves as an initiating timing unit for transmitting a synchronization analysis command message including a first parameter (t ) to the other of the timing units which serves as a responding timing unit. In response, the responding timing unit sends a synchronization analysis response message which includes at least second parameter (t ) and preferably a third parameter (t ) to the initiating timing unit. The initiating unit uses e.g., parameters extracted from the synchronization analysis response message to determine a synchronization adjustment value for the slave timing unit. When the master timing unit is the initiating timing unit, the master timing unit transmits the synchronization adjustment value in a synchronization updating command message to the slave timing unit.
