METHOD AND EQUIPMENT FOR CONTROLLING ACCESS TO MULTICAST IP FLOWS

摘要

The invention relates to a method of controlling access to multicast IP flows. Following connection to a collection equipment (CE) by a user terminal, the method consists in: transmitting (2) an access authorisation request message (AAD) from said collection equipment (CE) to an access control server (ACS); and, subsequently, upon successful verification (3) of the user access right, transmitting an access authorisation acceptance message (AAA) comprising at least one multicast filter from the server (ACS) to the collection equipment (CE) or, in the absence of a successful verification (3'), transmitting (4') an access refusal message (AAR) from the server (ACS) to the collection equipment (CE) in order to inhibit the connection of the user terminal. The invention is suitable for multicast broadcasting over an IP, Internet and/or corporate network.
