Control method for a communication relay system
View Patent ↗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 device 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.
1. A control method for controlling a communication relay system for providing a communication service to an existing communication network, comprising:
authenticating information from a primary and a secondary user wherein the primary user uses a primary user terminal receiving communication data through a fiber to a home communication line and the secondary user uses a secondary user terminal receiving communication data relayed from the primary user terminal through a power line communication line;
encrypting, via a first encryption system, a data communication from a source to a primary communication device connected to the fiber to the home communication line and the primary user terminal, wherein the encrypted data communication identifies the primary communication device;
relaying the encrypted data communication from the source to the primary communication device connected to the fiber to the home communication line and the primary user terminal;
determining whether the encrypted data communication is directed to the primary communication device or to a secondary communication device connected to the power line communication line and the secondary user terminal;
encrypting, via a second encryption system, the encrypted data communication, which is directed to the secondary communication device, to produce a twice-encrypted data communication;
passing the twice-encrypted data communication to the secondary communication device through the primary communication device after receiving authorization from the primary communication device;
charging a fixed monetary charge to the primary user for communicating performed in the relaying of the data communication to the primary communication device through the fiber to the home communication line; and
charging a reduced amount of the fixed monetary charge as a proportioned monetary charge to the secondary user based on a proportional amount of data packets sent and received by the secondary user of the data communication relayed through the fiber to the home communication line.
