    Patent number: 6804505
    Abstract: A method of determining a total call tariff in respect of a call from a Mobile Station currently registered with a foreign network. A total call tariff request is sent from a charging function of the foreign network to a rating node of the mobile telephone subscriber's home network, the message including a call tariff portion of the foreign network. At the rating node, the total call tariff is determined by applying a multiplying factor to the foreign network's tariff portion. The determined total call tariff is then sent to the charging function of the foreign network.
