1. The identification of the most efficient tariffs
Due to the considerable complexity of the utilisation structures and their cost effects in connection with the large number of possible tariff variants, it is practically impossible to determine the most efficient tariffs by conventional means.
For each user, the individual and complex telephony behaviour (call duration and data volume per target network, country, etc.) would first have to be recorded. In the case of large companies, this information alone can comprise millions of parameters for a required representative period. In addition, the costs of up to several hundred combinations of tariffs and tariff options with partly intransparent performance characteristics for the telephony behaviour of each user would have to be calculated for each provider.
Possible flat-rate pricing models can reduce complexity to some extent, but are commercially disadvantageous because of the correspondingly higher flat rates.
