Abstract
Information on the area occupied by a receiving terminal is present is passed to the sending terminal, prior to setup a call, in units of CAs (Cell Areas) that are smaller than LAs (Local Areas). Accordingly, the position occupied by the sending terminal can be specified, so that calls that are unnecessary due to that position do not have to be made, whereupon unnecessary tolls are avoided.
