Abstract
A computer-assisted method for monitoring a first time base of a first communication device and a second time base of a second communication device. First, Cristian's algorithm is used to calculate time offset intervals between the time bases. Second, the maximally possible drift of the time offset is ascertained multiple times for two measurement steps. A minimally possible drift is ascertained from the upper limit of the time offset interval for the previous measurement step and the lower limit of the time offset interval for the subsequent measurement step. The upper and lower limits of a drift interval are calculated from the maximally and minimally possible drifts. Third, the lowest upper limit is defined as the upper limit of a resulting drift interval, and the highest lower limit is defined as the lower limit of the resulting drift interval with narrow limits for the relative drift.
