A method for determining tentative locations for areas with poor radio coverage in a cellular communication system comprises the step of keeping position-related data of connected user equipment's updated in a network part of the communications system. The method further comprises detection of an accidental loss of connection to a user equipment. The position-related data of such a dropped user equipment is logged as a response to a detection of such accidental loss of connection. The logged position-related data for a multitude of accidental loss events are compiled as a quantity based on the number of accidental losses of connection as a function of the position-related parameter. The method further comprises identification of a tentative location for an area with poor radio coverage by statistical evaluation of that quantity. An arrangement for determining tentative locations for areas with poor radio coverage is also presented.
