<p>An access control method for multicast service in NGN network includes: the network access request sent by the user is authenticated by the network access control function (NACF), if the network access succeeds, the said NACF pushes the network configuration of the said user to the resource admission control function (RACF), and the network configuration of the said user includes the preset access control list; the said RACF pushes the access control list of the said user to the access device; after the said access device has received the multicast service request from the said user, whether to allow the said multicast service request to pass is decided according to the said access control list. By extending the multicast access control policy information of the interface between the RACF and the network transportation function, the operator can control the multicast service access of the user dynamically according to the network policy, reduce the effect to the network resource by the unsigned multicast service request, and save the network resource.</p> |
