Abstract
Abstract A temporarily saved band value management table for managing temporarily saved band value is provided, as is a band management table for managing empty band value in the storage device of an ATM exchange comprising a storage device, a control device, and the like. The control device selects a corresponding empty band value for a temporarily saved band value when a first camp-on request is received from a terminal, and sets the empty band value to “0.” In addition, the control device adds to the temporarily saved band value a band value released by a break in communication when a camp-on request is registered, and grants permission for communication to the terminal that has issued this camp-on request when the temporarily saved band value is higher than the band value required by a registered camp-on request. The control device determines whether or not a connection request can be accepted on the basis of the empty band value stored in the band management table.
