Communication method and communications control apparatus in circuit switching network
First Claim
1. A communication method of a circuit switching network, comprising the steps of temporarily disconnecting a circuit of the network, without ending a session, by a first communication control unit connecting a first terminal locally and a second communication control unit with a network, when no data is received from the network or when no data is to be transmitted to the network, and re-connecting by said first communication control unit the circuit that had been temporarily disconnected so that the session is resumed, when data to be transmitted is produced in the first terminal or when there is a request from a second terminal connected to said second communication control unit for a connection of the circuit.

Abstract
A communication control unit connecting a terminal and a network temporarily disconnects a circuit of the network without ending a session, when no data is received from the network or when no data is transmitted to the network. In response to an occurrence of the transmitted data in the terminal or in response to an occurrence of a request for the connection of the circuit, the temporarily disconnected circuit is re-connected so that the session is resumed.

19. A communication control unit comprising:
-
transmitted/received data state monitoring means for monitoring the presence/absence of data received from a network and data transmitted to the network; circuit connecting and disconnecting means for connecting and disconnecting a circuit in the network; and a control part for temporarily disconnecting a circuit in the network by said circuit connecting and disconnecting means when there is no data to be transmitted or when no data is received, while maintaining a session and keeping the other circuits connected, the temporary disconnection being performed on the basis of a monitoring result of said transmitted/received data state monitoring means, and for re-connecting the circuit that had been disconnected, when the data to be transmitted is produced by a local terminal or when there is a request for a re-connection of the circuit from a distant terminal with which the local terminal communicates via the network. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
