PROCEDURE FOR DETERMINING THE PAID OF PAYABLE TK SERVICES

摘要

The method involves calculating the currently arisen billing sum for an individual subscriber of a chargeable telecommunications service by device of a counter arrangement in a certain accounting period. After overstepping of a threshold value determined individually for the subscriber through the provider of the telecommunications services, a limited, cheaper, or preferably free of charge, use of the telecommunications services is made available to the subscriber.
