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. ## Claims ### Claim 1 A teleconference system featuring a call-up being a telephone service system comprised of a switching matrix, a VRE (voice response equipment) unit having a recording function and a call processing unit for executing a conventional call processing, an exchange connected with a group of terminals, such as telephone sets and terminal devices, having a plurality of users, each terminal corresponding with a respective one of said plurality of users and an SCP (service control point) for controlling various kinds of telephone line services, said telephone system featuring a call-up comprising: teleconference registration means for registering, in said telephone service system, a reservation for a teleconference run by any of the users of said group of terminals, for notifying all teleconference participants of said teleconference run, for responding to a status confirmation request for the date and time of said teleconference run, and for notifying an attending teleconference participant of a teleconference participant who will be absent; teleconference run means for holding a teleconference by automatically connecting all attending teleconference participants online on the date and time of said teleconference run registered by said teleconference registration means; SCP control means for controlling said teleconference registration means and said teleconference run means separately from controlling said exchange; and IN (intelligent network) call processing means for replacing an instruction by said SCP control means by an instruction controllable by said exchange. ### Claim 2 (depends on 1) The teleconference system featuring a call-up according to claim 1, wherein said teleconference registration means comprises: teleconference reservation notification means for registering a reservation of said teleconference run by any of the users of said group of terminals and for notifying all teleconference participants of said teleconference; teleconference status confirmation means for automatically responding to a status confirmation request by a teleconference participant for an updated status of the date and time of said teleconference run; and teleconference reservation notification means for notifying in a batch attending teleconference participants of an absence of a teleconference participant invited by said teleconference reservation notification means, on receiving his or her absence notice. ### Claim 3 (depends on 2) The teleconference system featuring a call-up according to claim 2, wherein said teleconference reservation notification means in said teleconference registration means: registers in a database, together with a teleconference ID (identifier), the date and time of said teleconference run and the names of teleconference participants specified by one of the plurality of users of said group of terminals, said one of said plurality of users being a teleconference sponsor; has said VRE record a voice message of said teleconference sponsor; and notifies each of said teleconference participants, specified by said teleconference sponsor, of said date and time of said teleconference run in a voice message. ### Claim 4 (depends on 3) The teleconference system featuring a call-up according to claim 3, wherein said teleconference reservation notification means in said teleconference registration means: deletes, from said database data on the date and time of said teleconference run, data on said names of teleconference participants and data on said teleconference ID, when said teleconference run having said teleconference ID is canceled; and notifies the teleconference participants of said canceled teleconference. ### Claim 5 (depends on 1) The teleconference system featuring a call-up according to claim 1, wherein said SCP control means: controls said teleconference registration means in an SCP (service control point) independent of said exchange; and issues an IN (intelligent network) message pursuant to a No. 7 common line signal system (SS7) to interchange instructions with said exchange. ### Claim 6 (depends on 1) The teleconference system featuring a call-up according to claim 1, wherein said IN call processing means: converts an IN (intelligent network) message sent from said SCP control means to said exchange to an instruction processable by said exchange; and sends, by converting to an IN message interpretable by said SCP, an instruction from said exchange to said SCP.
