ATM exchange
First Claim
1. A switching system for registering a camp-on when an empty band value corresponding to a band value requested from a transmitting terminal cannot be reserved, said switching system comprising:
- storage means for storing a band value requested from a transmitting terminal for which a camp-on is registered;
temporarily saved band value management means for adding an empty band value released by a disconnected call to a temporarily saved band value which is reserved for the transmitting terminal; and
camp-on execution means for executing the camp-on when the temporarily saved band value satisfying the band value stored in said storage means is gotten for the transmitting terminal by said temporarily saved band value management means.

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.

1. A switching system for registering a camp-on when an empty band value corresponding to a band value requested from a transmitting terminal cannot be reserved, said switching system comprising:
-
storage means for storing a band value requested from a transmitting terminal for which a camp-on is registered;
temporarily saved band value management means for adding an empty band value released by a disconnected call to a temporarily saved band value which is reserved for the transmitting terminal; and
camp-on execution means for executing the camp-on when the temporarily saved band value satisfying the band value stored in said storage means is gotten for the transmitting terminal by said temporarily saved band value management means. - View Dependent Claims (4)
notification means for notifying that the camp-on is executable to the transmitting terminal.

2. A switching system for registering a camp-on when an empty band value corresponding to a band value requested from a transmitting terminal cannot be reserved, said switching system comprising:
-
band management process means for managing an empty band value and a used band value on a transmission line;
camp-on registration process means for accepting a camp-on request from a transmitting terminal and for registering a camp-on for the transmitting terminal;
temporarily saved band value management means, when said band management process means detects an empty band value released by a disconnected call for adding the empty band to a temporarily saved band value which is reserved for the transmitting terminal for which the camp-on is registered as a part of the used band value, and camp-on execution means for executing the camp-on when the temporarily saved band value satisfies the band value requested from the transmitting terminal.

3. A switching system for registering a camp-on when an empty band value corresponding to a band requested from a transmitting terminal cannot be reserved, said switching system comprising:
-
band management process means for managing an empty band value and a used band value on a transmission line;
camp-on registration process registration means for distinguishing a class allocated for a transmitting terminal for which a camp-on is registered and for registering the camp-on for the transmitting terminal associating with the class;
temporarily saved band value management means, when said band management process means detects an empty band value released by a disconnected call for adding the empty band to a temporarily saved band value which is reserved for the transmitting terminal associating with the class of a higher priority among the transmitting terminals for which the camp-ons are registered as a used band value, and camp-on execution means for executing the camp-on when the temporarily saved band value satisfies the band value requested from the transmitting terminal.

5. A switching system comprising:
-
band management process means for managing an empty band value and a used band value on a transmission line;
camp-on registration process means, for registering a camp-on for the transmitting terminal when an empty band value corresponding to a band value requested from a transmitting terminal cannot be reserved; and
notification means for notifying the transmitting terminal of registration of the camp-on when said camp-on registration process means registers the camp-on;
wherein the switching system further comprises;
temporarily saved band value management means, when said band management process means detects an empty band value released by a disconnected call, for adding the empty band to a temporarily saved band value which is reserved form the transmitting terminal by which the camp-on is registered; and
second notification means for notifying the transmitting terminal that the camp-on is executable when the band value required from the transmitting terminal is gotten.
