ABSTRACT:
A spread-spectrum based cellular mobile radio system resolves average mutual interferences (I.sup.u (j).sub.av, I.sup.d (j).sub.av) between radio zones j, j') from a total interference experienced in a radio zone (j), using statistical methods. First, interference measurements are carried out in the radio zones (Z1, Z2), and data is transmitted to a central control arrangement (CA) which resolves the average mutual interferences. Then, these average mutual interference (I.sup.u (j).sub.av, I.sup.d (j).sub.av) are used in an optimization process for acquiring access control parameters (x) for controlling traffic per radio zone (Z1, Z2). In the optimizing process various objective functions may be applied so as to fulfil system operator demands. Thus, system overload is avoided, and further, a flexible tool is provided for satisfying operator demands.
