SYNCHRONISATION METHOD

摘要

The present invention relates to a method of synchronising a first communication device with a second communication device in a radio communication system, where the first and second communication devices comprise local clocks for obtaining local time signals. In the method the first communication device first receives (509) periodically a beacon signal from the second communication device, the beacon signal comprising a time signal of the second communication device and the quality of the time signal. Then the first communication device determines (512) quality of the local clock time signal of the first communication device, and determines (513) whether the received time signal is of higher quality than the local time signal of the first communication device, and in case the received time signal is of higher quality, then corrects the accuracy of the local clock of the first communication device.
