Designing system and method for computer-aided access communication networks

Abstract

An access communication network to make possible automatic designing a lower cost access communication network under various constraints by using existing equipment on the basis of demand information is to be provided. The equipment is classified into communication equipment and civil-engineered equipment; information is given, before automatic designing, as to whether each item of equipment is to be deleted or its position is fixed to use its unoccupied capacity; and allows the designer to freely define an eligible deployment site for the equipment and thereby to calculate the configuration of a low deployment cost access communication network and civil-engineered equipment needed therefor. First, equipment information is read in (,), parameters including the number of current additional demands, the cost of each equipment item and the design policy are defined (,), the communication/civil-engineered equipment items are edited if necessary (,), designation is given for each equipment item whether or not to use it in automatic designing by an addition formula (,), and a low deployment cost access communication network is calculated by fixing the positions of those items of equipment for which the addition designing mode is designated and using them as being free of additional equipment cost.
