Abstract: PURPOSE: A method for transmitting charging information of a full electronic exchange is provided to collect charging files in a centralized automatic message account(CAMA) processor whenever the charging files are generated, after the exchange sets up a real time session, and to transmit the collected charging files to a charging collection center, so that the charging collection center can reliably collect the charging files in real time. CONSTITUTION: If a request for transmitting charging files is generated from a charging collection center, a centralized automatic message account(CAMA) processor transmits a signal for requesting a real-time session setup to a charging transmission processor of a switching system. The charging transmission processor sets up a real-time session, and checks whether the charging files are generated. If so, the charging transmission processor transmits information on the generated charging files to the CAMA processor. If a request for transmitting charging data is generated from the CAMA processor, the charging files are open to be cut off as inter processor communication(IPC) packet units, and transmitted to the CAMA processor. If charging file transmissions are completed, the charging transmission processor transmits transmission-completing packets relating to the charging files to the CAMA processor. If the transmission completing packets are received, the received charging files are transmitted to the charging collection center. If the charging file transmissions are completed, the CAMA processor transmits the transmission completing packets to the charging transmission processor. The charging transmission processor updates information on the charging files, and enters a stand-by state to monitor whether new charging files are generated.
