TELEPHONE CALL BILLING SYSTEM

摘要

The cost of a telephone toll call is shared by arranging the billing system of the telephone toll carrier to permit sharing of the period cost for at least one indivisible time period of a toll call. Accordingly, at least a portion of the period cost associated with at least one of the indivisible time periods of a toll call is assigned to both the terminating and originating subscribers, so that each subscriber to the toll call is billed for a portion of the total basic cost incurred for each of those indivisible periods of time over which it is agreed that the period costs will be shared. Anauthorization signal, indicating that the subscriber who would not have shared in the period costs for any indivisible period if the call had the call been placed as in the prior art--typically the terminating subscriber--agrees to accept his share of the period costs, may be required before any period cost sharing periods can occur.
