A positional information tracking and forwarding method is disclosed for conducting an optimal forward destination control method to estimate the situations of a user. A position database stores a plurality of forward destinations for a call to the user that correspond to positional information and time period information (business hours or the like) of the forward destinations. This is used as a search table. For forwarding a call to the user, the current position of the user is detected from the position of a mobile telephone carried by the user, and a forward destination list is created based on the detected current position of the user, the current time, and the search table. The forward destination list enumerates forward destinations that are arranged in an order in which the user is more likely to be present at the forward destinations. The forward destinations are selected one after another in accordance with the forward destination list to forward the call to the user.
