Method for costing calls during roaming esp. for mobilephone networks, involves forming costing level from first and second costing components

摘要

A method for approving a link between a first subscriber in a first communication network to a second subscriber in a second communication network which is linked to the first network, in which the level of costing is compiled from a first costing component for the link in the first communication network, and from a second costing component for the link in the second communication network. A communication link is set up only if the first subscriber of both costing components concur. The second subscriber is deposited, before the setting up the link, when he does not agree on the costing component for the second communication network, case A, and case B, in which the first subscriber (Tin) is deposited, before the communication link is established, and that he agrees on the costing component for the second communication network (ADD). An independent claim is included for a device in a communication network for carrying out the method.
