Abstract
If the location cell of a calling subscriber or a called subscriber belongs to a set of special cells at the beginning of a call, a cheaper tariff is applied. According to the invention, the charging criterion is updated in the beginning and during the call. If a subscriber roams from the area of a public network cell to the set of special cells, the cell information propagates to the MSC of the called subscriber. The MSC and/or service control point compares this cell information with the set of special cells and determines that the new cell of the called subscriber belongs to the special cells, due to which the tariff can be changed. Information on the called subscriber's changed cell type is transmitted to the mobile switching centre of the calling subscriber.
