A computer implemented method for identifying a stationary user device of a communications network. This is performed by obtaining (301) usage data from the communications network; analysing (302) the usage data to check whether a user device fulfils the conditions of a stationary user device; responsive to finding that the user device fulfils said conditions of a stationary user device, concluding (303) that the user device is stationary; and outputting (304) information about the user device being stationary for the purpose of further analysis and/or management of the communications network. The conditions of a stationary user device require that the amount of data transmission to or from the user device exceeds a first threshold, and that the user device has been connected to a predefined maximum number or fewer base stations or cells.
