The invention proposes a method of determining communications network service trends. The invention therefore selects two or more parameters of a network representative of a network service and variable in time, measures at two or more times values of the network parameters, determines at two or more times the value of a service indicator as a function of said measured parameter values, and determines a trend of the indicator as a function of said determined indicator values. The method is used in particular to determine a time remaining before a service violation or the crossing of a threshold.
