The present invention relates to a method for configuring a base station (10) of a mobile communication network over a software defined radio module (12), that base station (10) serving at least one mobile terminal (20, 30, 40) over an air interface (52, 53, 54) served by that software defined radio module. When selecting the communication standard for the configuration of the base station (10) the characteristics of the air interface (52, 53, 54) are taken into account. The invention also relates to a base station (10) of a mobile communication network, that base station (10) serving at least one mobile terminal (20, 30, 40) over an air interface (52, 53, 54), that base station (10) comprising a configurable software defined radio module (12). The configurable software defined radio module (12) is adapted to take into account the characteristics of the air interface (52, 53, 54) when selecting the communication standard for the configuration of the base station (10).
