+1 to Harald. Doing traffic accounting at the PGW and then reporting these statistics over
Diameter is probably the most architecturally correct way to do this. I'm definitely a
fan of using IPTables for this kind of stuff, since it’s all just packets anyways.
For our networks, we wrote a completely separate tool called haulage
(
) that uses IPTables and does something very similar.
Basically logs packets that are forwarded from the virtual interface, draws them down
against a user’s prepaid quota, and cuts them off when they hit zero. We wrote this as a
separate app (in go) mainly to keep things simpler and let us move faster.

Freediameter should be able to provide accounting
so long as the ENB
supports it.
in which way is the eNB involved in traffic accounting in LTE?
Normally, AFAICT, accounting is implemented within the P-GW, potentially
interacting via Radios/Diameter or some other protocol with some external
entity that decides whether or not there is credit/budget remaining or not.
If not, the PGW would stop firwarding packets of the related
session/subscriber.
