A method and apparatus for selecting a value of at least one network operating parameter, cell operating parameter, radio resource management parameter or dimensioning parameter for a cellular radio communications network having a base station and mobile units communicating therewith is described. A statistic is maintained of estimated mobile unit occurrence densities or estimated changes of mobile unit occurrence densities at locations in a cell. The selection of the value of the at least one network operating parameter, cell operating parameter, radio resource management parameter or a dimensioning parameter is made in accordance with an occurrence frequency density stored in the statistic. The apparatus and method are particularly suited for detection and remediation of hot spots.
