ABSTRACT:
A call processor performs call set-up/release processing based upon absence/presence of valid data from an SVC service terminal and either decreases or increases an idle band of the network by an amount equivalent to the assigned band of the SVC service terminal. Further, the call controller sends a network an OAM cell for band assignment or am OAM cell for canceling band assignment based upon absence/presence of valid data from a PVC service terminal and either decreases or increases an idle band of the network by an amount equivalent to the assigned band of the PVC service terminal. In a case where the transfer rate of data sent from terminal is high, a band assignment controller send the network an OAM cell for retesting band increase, increases the assigned band of the terminal by a prescribed amount and decreases the idle band by an amount equivalent to the increase in the assigned band. In a case where the transfer rate of data sent from terminal is low, the band assignment controller sends the network an OAM cell for requesting band decrease, decreases the assigned band of the terminal by a prescribed amount and increases the idle band by an amount equivalent to the decrease in the assigned band.
