For the access-point dependent calculation of telecommunication rates by way of a network, connecting data is generated in response to obtaining and using, by a subscriber or group of subscribers, telecommunication links. The connection data contains data identifying a network-access point used by a subscriber. During a specific period of time, there is stored connecting data in a connecting-data file. By, as a function of data on access points used in the period of time by a subscriber or a group of subscribers, determining to which of the access points there are coupled rates specific to the subscriber in question or group of subscribers, access-point-dependent rating is made possible in a simple and automatically self-regulating way. A system for applying the proposed way of rating is described as well.
