Abstract
The present invention concerns an exchange control method, wherein an old host exchange accommodating a remote switch unit or subscribers is adapted to be accommodated in a new host exchange, and its object is to allow call processing control to be performed by the new host exchange while making effective use of the resources of the old host exchange including the remote switch unit. The new host exchange and the old host exchange are connected in an interoffice configuration by a signaling link, and each exchange includes an emulation processor; the old host exchange and the new host exchange perform message editing and exchange between the respective emulation processors, and exchange control is performed in such a manner that when there occurs data or a request for basic control that is normally processed at the old host exchange, the data or request is transferred to the new host exchange, and the new host exchange processes the data or request and sends a notification to the old host exchange.
