摘要： Provided are a method of and system for controlling IPTV service authentication and traffic flow in an access network. The IPTV service system comprises: a subscriber concentrator which delivers an IPTV service request message that is sent from a subscriber terminal, receives an IPTV service authentication reply message generated in accordance with IGMP in response to the IPTV service request message, and sends a corresponding IPTV multicast stream to the subscriber terminal according to an IPTV service authentication result; a network connector which receives the IPTV service request message delivered from the subscriber concentrator, generates an IPTV service authentication request message in accordance with a RADIUS protocol, sends the generated IPTV service authentication request message to an IPTV service authentication/billing server, generates an IPTV service authentication reply message in accordance with the IGMP when receiving an IPTV service authentication reply message generated in accordance with the RADIUS protocol, and sends the generated IPTV service authentication reply message to the subscriber concentrator; and the IPTV service authentication/billing server which determines whether the subscriber is authorized for an IPTV service when receiving the IPTV service authentication request message that is generated in accordance with the RADIUS protocol and sent from the network connector, and generates the IPTV service authentication reply message in accordance with the RADIUS protocol and sends the IPTV service authentication reply message to the network connector. Accordingly, resources of the access network can be used effectively.
