Abstract:
1. An exchanger connected to external terminals and an external server through a network and connected to exchange-connected terminals, the exchanger comprising: an exchange server portion; pseudo exchange-connected terminal portions; pseudo external terminal portions; a database, and a pseudo external terminal and pseudo exchange-connected terminal portion, wherein the exchange server portion is adopted to connect the exchange-connected terminals to each other; the pseudo exchange-connected terminal portions correspond to respective external terminals and function as exchange-connected terminals with respect to the exchange server portion; the pseudo external terminal portions correspond to respective exchange-connected terminals and function as external terminals with respect to the external server; the database retains corresponding relations between a first user identification used in the exchange-connected terminals and a second user identification used in the external terminals; the pseudo external terminal and pseudo exchange-connected terminal portion retrieves the second user identification associated with the first user identification from the database, retrieves the first user identification associated with the second user identification from the database, functions as an exchange-connected terminal with respect to the exchange server portion by using the first user identification, and instructs one of the pseudo external terminal portions to function as a corresponding external terminal with respect to the external server based on the second user identification; access from a user to the exchanger is carried out through at least one of the exchange-connected terminals; and the pseudo exchange-connected terminal portions, the pseudo external terminal portions and the pseudo external terminal and pseudo exchange-connected terminal portion are independent with respect to one another.
