Method for controlling costs for mobile telephone stations uses groups of cells assigned to base transmitter/receiver stations to manage charges imposed on adjacent cells in different telephones.

摘要

A mobile telephone is located within a transmission area for a cellular communications network with multiple cells allocated to corresponding base transmitter/receiver stations. The network has a sub-area formed by a sub-group of cells within the network. A telephone device i.e. a mobile station is charged with a lower tariff compared to adjacent cells. An Independent claim is also included for a mobile telephone station for use in a cellular communications network.
