3 Signalling aspects

For user trigger, the operators can provide such pages/functions in the portal to allow users to order and
modify the smart policy. When the user modifies the policy, the distribution of new control policy is
automatically triggered by the service platform and distributed to the BNG.
The BNG can also provide smart user traffic monitoring function with some user traffic monitoring and
analysis device, which can be line card/mode for service monitoring within the BNG. The BNG can monitor
and analyse the real-time user traffic. When the user traffic meets the pre-defined condition, the BNG will
notify the service platform. Then the service platform can push portal pages to the user side by the way of
re-direction. The user can know the statistics of its service traffic and order/modify the pipe policy to enhance
the service quality. After the user order/modify the control policy, the distribution of new control policy will
be automatically triggered.

Other devices can also possibly trigger the modification of control policy. Suppose the BNG works together
with individual CGN or DPI devices. When the CGN or DPI device finds user traffic abnormal, it can inform the
service platform. The service platform can choose the appropriate control policy and distribute to the BNG.
The user traffic might be limited, and the user will be notified through portal page pushing technology.
The service platform/BNG can also receive the configuration commands from the NMS through SNMP or
other protocols, and the new control policy will be accordingly generated and distributed.
