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) 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.

Hi David,

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.
