Determining communications network with best tariff for connections via different operator networks involves additionally transmitting tariff precedence/determination in signaling channel

摘要

The method involves transmitting an operator identification (CDPCIC) indicating the tariff precedence of each operator and implementation information (CCDONE) indicating the tariff determination as additional information in the signaling channel (ISUP). The additional information can be formed in the original network or exchange or in one of the other operators' networks.
