1. A supplemental service meter gateway comprising:
- a power measurer for implementing a high-speed power line communication with a regional information control device via subscriber networks, implementing a high-speed power line communication with terminals of dwellings via residential home indoor networks, and reading the accumulated power of the dwellings from the residential home indoor networks to provide the reading data to the regional information control device via the subscriber networks; and
a service measurer for providing to the terminals service data supplied from the regional information control device via the subscriber networks in response to a request signal from the terminals and measuring the service data based on type of service/content, used service time, service/content download frequency, content information quantity, unit information, and control service providing frequency to transmit the measured service reading data to the regional information control device.

26. A power line communication method, the method comprising the steps of:
-
(a) registering a common code key and/or private code key with a regional information control device, supplemental service meter gateway, residential home indoor information control device and terminal;
(b) prompting a subscriber to manipulate the residential home indoor information control device to transmit a service data request signal to an external server;
(c) prompting the outside server to transmit service data to the regional information control device via a data communication network in response to the service data request signal;
(d) prompting the regional information control device to encode the service data by using the common code key, and transmitting a first encoded data to the supplemental service meter gateway via subscriber networks;
(e) prompting the supplemental service meter gateway to decode the first data by using the common code key and to encode the first data again by using the private code key, and to transmit a second encoded data to the residential home indoor control device and the terminal via the residential home indoor network, and to measure the first data decoded based on the type of service/content, used service time, service/content download frequency, content information quantity, unit information, control service providing frequency to again encode the measured reading data by using the common code key and to transmit a third encoded data to the regional information control device via the subscriber networks;
(f) prompting the regional information control device to use the common code key to decode the third data and to transmit the decoded third data to the external server via the data communication network; and
(g) prompting the external server to allocate a service data charge based on the decoded third data. - View Dependent Claims (27)
