Teleconference system featuring a call-up

Abstract

When a teleconference sponsor wishes to have an SCP (service control point) for controlling an IN (intelligent network) service reserve a teleconference run, a teleconference reservation notifier in a teleconference registerer has the teleconference sponsor input data on the date and time of the teleconference run and data on the names of teleconference participants. This registers the teleconference, and notifies all the teleconference participants of a schedule of the teleconference run. When a teleconference participant wishes to receive data on the date and time of a teleconference run, a teleconference status confirmer in the teleconference registerer reads the registered data of the teleconference run, thereby notifying the interrogating teleconference participant. When a teleconference participant cannot attend a teleconference, a teleconference absence notifier in the teleconference registerer receives his absence notice, and notifies all other attending teleconference participants of his absence. On reaching the reserved date and time of a registered teleconference, a teleconference executor in the SCP automatically puts all the attending teleconference participants online. An SCP controller in the SCP performs the entire control of the teleconference registerer and the teleconference executor, as well as an interface with an exchange. The IN call processor in the exchange performs the interface with the exchange by a conversion between a message for use by the SCP and a message for use by the exchange, which is a conventional exchange.
