The invention concerns a method of detecting an outage of a radio cell (C1) in a wireless telecommunication network (N), and a base station (B1 to B4) to execute this method. The network (N) comprises a plurality of radio cells (C1 to C12) and two or more base stations (B1 to B4). Each radio cell (C1 to C12) is associated with a base station (B1 to B4) providing telecommunication service to at least one user terminal inside the radio cell (C1 to C12). At least one of said base stations (B1 to B4) determines for at least one (C2 to C7) of the radio cells (C1 to C12) associated with the at least one base station (B1 to B4) values of one or more RF-signal related parameters associated with at least one user terminal inside the at least one radio cell (C2 to C7). From the determined values of the one or more RF-signal related parameters, one or more indications corresponding to the one or more RF-signal related parameters are determined. Said one or more indications are compared with respective references. If an indication differs from the respective reference in excess of a predefined threshold, a respective trigger event is generated. Dependent on one or more of said respective trigger events, it is indicated that one or more neighbouring radio cells (C1) neighbouring the at least one radio cell (C2 to C7) associated with the at least one base station (B1 to B4) are affected by an outage.
