Determining telecommunication network side expense for calculating tariff charges

摘要

The present invention relates to a telecommunication network and to a method for the optimal definition, on a telecommunication network side, of the complexity (6), on the telecommunication network side, of a desired or existing telecommunication link (6) between two subscribers (1, 7) in order to determine the rate. According to this invention, one subscriber is a mobile subscriber (1) having a mobile radiotelephone, while the other is a fixed subscriber (7) connected to a fixed network. The position (2, radio cell 23a) of the mobile subscriber (1) is then detected. A local call is detected in the case of a telecommunication link (40) between the mobile subscriber (1) and a fixed subscriber (4) whose connection to the fixed network is located, due to the fixed network code, within a local area (3) surrounding the position (2, radio cell 23a) of the mobile subscriber (1). A toll call, which is relatively more expensive than a local call, is detected in the case of a telecommunication link (6) between the mobile subscriber (1) and a fixed subscriber (7) whose connection to the fixed network is located, due to the fixed network code, out of a local area (3) that can be predetermined and that surrounds the position (radio cell 23a) of the mobile subscriber (1).
