The problems of satellite charges with reduced G/T stations for different pre-assigned and demand-assigned modes of operation are considered. A mixed pre-assigned demand-assigned operation is assumed as a model, in which large standard stations use the demand-assigned system for their overflow traffic. Determination of the optimum percentage of overflow for each link and of the global satellite revenue and occupancy, in terms of a general traffic matrix, is carried out and then used in the specific case of the Atlantic satellites to establish demand-assignment and pre-assignment charges as a function of G/T, based on a cost per unit bandwidth criterion. The effects of various demand-assignment systems on the economic balance is also considered. 相似文献
