Abstract
Connected relay stations of a network each include a network number, a clock ( ) defining a local reference time, a module ( ) for transmitting/receiving messages on a frequency varying according to a selected time-division scheme defined relative to the local reference time, and a control module ( ) for the messages. The control module of a synchronising relay station (SH) forms synchronisation messages including its network number, a common frequency, its time-division evolution scheme and a common reference time, for the transmission thereof. In addition, each relay station (SH) includes a synchronisation module ( ) capable of extracting the information contained in a synchronisation message received bearing a common network number, in order, on the one hand, to readjust the local reference time defined by the clock ( ) to the common reference time and, on the other hand, to provide the transmitting/receiving module ( ) with the common frequency extracted and its time-division scheme, such that the relay station is frequency-synchronised with the synchronising station and in turn becomes a synchronising station.
