Our migration is *almost* done. We had to rewrite a lot of database code because we used
to integrate with OAI, but now have moved our systems over to open5gs. I’ll respond back
to this thread once we’ve finally migrated everything (should be by the end of the week).

Hello Spencer, Harald and all.
I really appreciated all infos, this saves me a lot of time!
Spencer, I'm seeing your tool, I think that is exactly like I need. My environment is
small (10 endbs).
I will try to use your tool here, In our github page you inform that the code is
migrating to open5gs. It's working with the open5gs?
Thanks

+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
(https://github.com/uw-ictd/haulage <https://github.com/uw-ictd/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.

Sorry yeah I meant the EPC. I am not sure if the Open5GS software supports
it but Freediameter would be the Accounting portion in AAA from what I can
tell.

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.
