Abstract
The present invention relates to a dummy burst structure used in a cellular digital radio-communications system operating on the principle of time division multiple access, each cell in the system being associated with a beacon frequency subdivided into periodically-repeated frames, each of which comprises at least one signalling channel or beacon path for transmitting signalling messages to mobile stations, the other channels serving in particular to transmit useful data, the burst being transmitted over those channels of the beacon frequency which are not assigned to transmitting useful data, or over certain time slots of the signalling channel when there is no signalling data to be transmitted over the certain time slots, wherein the burst contains a signalling message.
