Communication relay system, control method, program and information processing system

摘要

In a case where a secondary use of a communication line which is provided as a communication service is permitted, an appropriate communication charge to be charged to each user is computed in order to promote the use of the communication line. There is provided a communication relay system providing communication service which connects a communication device to an existing communication network. The communication relay system includes a communication relaying unit which connects a primary communication device connected to a predetermined primary communication line to the communication network to relay communication between the primary communication device used by a subscriber and the communication network; an account database which records a communication charge for communication performed by the primary communication deice with the communication relay system through the primary communication line; and an accounting unit which reduces the amount of the communication charge recorded in the account database, if another subscriber connects a secondary communication device to the primary communication device and the communication relaying unit connects the secondary communication device to the communication network through the primary communication line.
