PURPOSE:To inform the result of relay without charge imposed by storing the notice of the result of relay based on the instruction of other terminal equipment and implementing the relaying on a packet line through the use of a relay instruction serial number and a relay destination serial number. CONSTITUTION:A relay station 22 sends a relay result notice ID as a relay result notice 701, the relay instruction serial number, a relay destination serial number, relay result, and a relay result error code to a relay instruction station 21 through a packet line. The relay instruction station 21 checks whether or not a relay instruction serial number corresponding to a received relay result notice 701 is present on a relay instruction table 601 and references a relay destination table 602 of the relating instruction serial number when the serial number is present thereon. The relay instruction station 21 checks whether or no the relay destination serial number relating to the relay destination table is present thereon and reconstitutes the relay result table and the relay destination table in the case of presence. In this case, when no record is present on the relay destination table 602 having the relay instruction serial number, the relay instruction station 21 reconstitutes the relay instruction table 601. Thus, the notice of the relay result is implemented without charge imposition. |
