METHOD FOR PROVIDING LONG DISTANCE TELEPHONE CHARGE AND METHOD FOR DESIGNATING ROUTE OF LONG DISTANCE TELEPHONE

摘要

PURPOSE: To obtain a method used for a remote communication service supply trader in a remote communication system with a working data base. ;CONSTITUTION: Inter-switching network communication traders 10 and 20 can obtain charge information for a long distance telephone service in a charge data base. A private branch exchange 40 and a telephone central station 31 perform access to the charge information by using a synthetic digital communication service network and/or SS7 type signal transmission. This charge information is used as a reference for deciding which communication trader should be used when it is applied during the designation of the route of the call. This access can be performed with reference for each calling. On the other hand, the charge schedule of the communication trader can be stored in one part of the private branch exchange 40 or in a private branch switchboard. Thus, it is not necessary to inquire to the charge data base for each call.;COPYRIGHT: (C)1994,JPO
