Claim:
A method for dimensioning different hardware components at a base station of a CDMA mobile communication network, wherein the hardware components comprise modems and channel elements, wherein for each base station a minimum number of hardware components is determined for which the predefined blocking probabilities are observed, wherein in the case of restricted “soft” capacity in consideration of on-net interferences, the hardware components are dimensioned in such a way that the “soft” blocking probability, in the case of unrestricted hardware resources, is increased by no more than a predefined factor, comprising the following steps: dimensioning the modems and channel elements separately from one another, wherein a fixed lower bound is assumed for the number of required modems M min and channel elements C min , calculating the blocking probabilities for this initial configuration of C min , and M min , wherein modems and channel elements are jointly considered and soft blocking is included in the uplink and downlink; in the case of predefined blocking probabilities being fulfilled for all sectors of the base station, the dimensioning method is concluded or otherwise it is distinguished whether the soft capacity has already been reached for all sectors; wherein in the positive case the hardware components are reduced so far that the blocking probabilities are above the pure soft blocking probabilities by no more than a value θ, and otherwise the number of hardware components is further increased, wherein the number of modems for the constant C min channel elements is increased until no more blocking by modems occurs, and also the number of channel elements for M min modems is increased, wherein this increase of the modems and channel elements is performed until either the desired blocking probabilities are reached or no more reduction of the blocking probabilities is achieved through additional hardware, since the soft capacity is achieved in the corresponding sectors, wherein the C max and M max resulting from this represent an upper limit for the required modems.
