PURPOSE:To realize the know services in either of the single network and the inter- network connection by informing previously the immediate information register number to the terminal when the call connection is set up and then informaing the charging information to the terminal after giving the call again and informaing the number to the network. CONSTITUTION:With call given from data terminal 20, telephone exchange 21, packet multiplication device 30, packet exchange 35 and packet terminal 31 are actuated. And if the immediate information request is given, exchange 35 gives allotment to the information gathering area and the know register number. Under communication, the charging information is collected to the memory of main memory device 33 corresponding to the number. The charging information is preserved for a fixed time even after breaking of the call, and data terminal 20 transmits the known request based on the register number. Thus exchange 35 draws out the corresponding information from the gathering area and sends it to device 30 to then transmit the charging information contained in the information transmitted to terminal 20 by one character. |
