ABSTRACT:
A system, device, and method for receiver access control in a multicast communication network uses a policy service to determine whether a subscriber device can be admitted to a multicast group. The subscriber device accesses the multicast communication network via an access device. The access device uses a policy service to obtain a policy decision from a policy server, where the policy decision indicates whether or not the subscriber device can be admitted to the multicast group. The access device enforces the policy decision by admitting the subscriber device to the multicast group if and only if the policy decision indicates that the subscriber device can be admitted to the multicast group.
