Abstract: The invention relates to an information delivery system and, more particularly, to the provision of a content delivery system that properly bills a user when delivering content such as music and moving images to the user by means of streaming over the Internet. The system for delivering the content over the network comprises: a subscriber serving apparatus serving the user; a delivery server for delivering the content; and a billing server for billing for the delivery of the content, wherein the subscriber serving apparatus includes monitoring means for monitoring the data stream being delivered from the delivery server to the user, and the billing server includes judging means for judging whether to bill or not bill the user based on the delivery quality of the monitored data stream, and bills the user based on the result of the judgment made by the judging means.

Abstract: In a subscriber apparatus and a subscriber line concentrator used for an Internet connection service or the like, the subscriber line concentrator comprises a communication control unit multiplexing/demultiplexing packets from a subscriber I/F and a network connection I/F, the network I/F converting the formats of packets from the communication control unit and the network, a transmitting/receiving unit being able to transmit recorded usage period information data to a communication managing apparatus, and a recording unit recording the usage period information data relating to a connection history between the subscriber apparatus lent from a communication carrier and the network, which prevents communication for grasping the state of usage of the subscriber apparatus from suppressing the communication bandwidth used to provide the network service to the subscriber, and carry out an efficient packet processing in an access line in the network.

Abstract: In a call distribution control method for terminating an incoming call from a trunk or another extension at a pilot extension in a private branch exchange and routing the incoming call from the pilot extension to an idle agent in an agent group, a routing table corresponding to the pilot extension is provided for designating one or plural agent groups to which the incoming call is to be routed. Priorities are assigned to agents constituting the agent groups, and an agent group to which the incoming call is to be routed is decided, based upon the routing table when the incoming call is terminated at the pilot extension. The incoming call is routed to an idle agent, in the order of priority thereof, in the agent group to which the incoming call has been routed. Further, a prescribed agent is allocated to a plurality of agent groups upon assigning a priority to this agent.

Abstract: A device for receiving cells with varying time delays and for reconstructing a continuous signal from a sequence of the cells includes a delay absorbing unit for receiving, temporarily storing, and sending cells after absorbing a variation in time delays of the cells, a cell disassembling unit for reconstructing the continuous signal by processing the cells sent from the delay absorbing unit, and a cell counting unit for counting a number of the cells stored in the delay absorbing unit, wherein the cell disassembling unit starts processing a new cell when the number exceeds a predetermined number, so that a time delay of the continuous signal can be reduced.
