The following AVPs identify NAS filter inserts that are applied to a subscriber host. Those AVPs can be included in CCA-i, CCA-u or RAR message sent from the PCRF.
Charging-Rule-Install ::= <AVP Header: 1001>
Charging-Rule-Definition <AVP Header: 1003>
Charging-Rule-Name <AVP Header: 1005> = ‟allow-all”
Alc-NAS-Filter-Rule-Shared <AVP Header: 158> = "permit in ip from any to any "ASCII NUL" permit out ip
from any to any"
In this example, the filter entry defined in Alc-NAS-Filter-Rule-Shared AVP is inserted in the clone of the existing base filter for the subscribers.
