In a hierarchical cell structure, the parameter for setting a signal strengt h threshold which determines the selection of serving cell, along with the preference rating of umbrella macrocells, microcells and picocells in a cellular telephone system, is related to a quality criteria, such as speech quality. The "sufficient signal strength" threshold is automatically tuned according to the quality criteria thereby avoiding the need for expensive, time consuming manual adjustment of this parameter.
