A communication device, method and system in which tariff information is provided to a communication device from a control station at call setup, and the charges associated with a call can be calculated and displayed to a device user at the device itself, rather than at a central communication system processor. The tariff information includes the current tariff, future tariff, and time of tariff switch. By providing the tariff information to the communication device, significant signal processing resources at the central communication system processor can be saved.
