I don?t, but I would love to hear what you find out. Also, to my understanding right now the PCRF is a bit of a stub process and simply says ?OK? to all requests right now.

Hello all and @Sukchan Lee <acetcom at gmail.com>,

I was thinking about one way to generate traffic accounting from the LTE
users of the Open5GS.

I'm rearching something using the iptables (in Linux), in this link we can
check a way to generate some traffic account in the linux:
https://catonmat.net/traffic-accounting-with-iptables

I'm thinking about writing a code, where the PGW adds a new line in
iptables with the IP/IPv6 address (TRAFFIC_ACCT_IN and TRAFFIC_ACCT_OUT)
when a new session is added and remove the same line when the session is
ended, with this the counter will restart, being able to use an external
program to get this information about the traffic sent and received by a
given user.

The bad from this idea is that this code only will work correctly in a
Linux box.

Does anyone have any other suggestions?

Thanks

Romeu Medeiros

Freediameter should be able to provide accounting so long as the ENB supports it.

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.

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.

+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.

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

Romeu Medeiros

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).

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.

great!

> I'm rearching something using the iptables (in Linux), 

Please don't.  iptables is mroe than 20 years old by now, and for any
new development you should consider using nftables.  It is much more powerful,
efficient nad also (contrary to iptables) has nice library API by which rules
can be installed from programs without fork+exec of an "iptables" binary with
command line arguments.

In Debian 10 (and presumably other distributions) nftables is alredy the default.
Based on the fact that there's an iptables compatibility layer on top, you may
not even know that.

The fundamental question is whether or not you want to do this in the external
packet filter of the OS or inside the PGW itself.  I would argue for the latter,
because:

> The bad from this idea is that this code only will work correctly in a
> Linux box.

that, and also because the open5gs PGW already contains a (stripped
down) BSD firewall code base if you want to do filtering or the like.

In general, the question is what kind of throughput in terms of
bandwidth and pps you are looking for.  Implementing GTP-U encap/decap,
accounting, filtering etc. inside a userspace process behind RAW sockets
and a tun device is not going to scale very far.  For a single-eNB lab
setup: Fine. But do you need accounting there?

For anything bigger, I would consider looking at other P-GW
implementations out there, such as ergw or the OMEC implementation.

They both do CUPS (control / user plane split) and have DPDK and/or VPP
accelerated user plane implementations.  Given they talk standard GTP,
you should be able to inter-operate them with open5gs.

Regards,
	Harald

Hi david,

If pcap is provided, it is more easier to analyze your problem.

BTW, from your log, I've found PDN connectivity reject with ESM_CAUSE:27.
It means that UE APN is unknown in HSS. So, you need to match APN name
between UE and HSS.

Thanks and regards,
   Sukchan

I figured out what was going on, so perhaps there is a solution already in place.  By default the Baicells UE do not request a specific APN.  That causes the EPC to reject the request.

Hi david,

 

If pcap is provided, it is more easier to analyze your problem.

 

BTW, from your log, I've found PDN connectivity reject with ESM_CAUSE:27.

It means that UE APN is unknown in HSS. So, you need to match APN name between UE and HSS.

 

Thanks and regards,

   Sukchan

Even though UE try to connect without APN, if you set the first APN(default
APN) to the mongoDB, open5gs won't reject the UE request. If the problem is
still not resolved, I need your pcap file to fix the issue.

I will get you a pcap.  The UE actually don?t have an APN listed by default.

Even though UE try to connect without APN, if you set the first APN(default APN) to the mongoDB, open5gs won't reject the UE request. If the problem is still not resolved, I need your pcap file to fix the issue.

I figured out what was going on, so perhaps there is a solution already in place.  By default the Baicells UE do not request a specific APN.  That causes the EPC to reject the request.

Hi david,

 

If pcap is provided, it is more easier to analyze your problem.

 

BTW, from your log, I've found PDN connectivity reject with ESM_CAUSE:27.

It means that UE APN is unknown in HSS. So, you need to match APN name between UE and HSS.

 

Thanks and regards,

   Sukchan

I have used internet as the default and some of the UE still do not come online.  Logging into the web interface it shows no APN listed.  I am looking to not have to touch each UE if possible.

Hi David,

Baicells CPE has "internet" set as APN by default.

And you can make changes to the APN name under APN management field.

Even though UE try to connect without APN, if you set the first APN(default APN) to the mongoDB, open5gs won't reject the UE request. If the problem is still not resolved, I need your pcap file to fix the issue.

I figured out what was going on, so perhaps there is a solution already in place.  By default the Baicells UE do not request a specific APN.  That causes the EPC to reject the request.

Hi david,

 

If pcap is provided, it is more easier to analyze your problem.

 

BTW, from your log, I've found PDN connectivity reject with ESM_CAUSE:27.

It means that UE APN is unknown in HSS. So, you need to match APN name between UE and HSS.

 

Thanks and regards,

   Sukchan

I believe the issue is with some UE not all of them.  Unfortunately there are a lot  out there I have to deal with.

Hi David,

Baicells CPE has "internet" set as APN by default.

And you can make changes to the APN name under APN management field.

Even though UE try to connect without APN, if you set the first APN(default APN) to the mongoDB, open5gs won't reject the UE request. If the problem is still not resolved, I need your pcap file to fix the issue.

I figured out what was going on, so perhaps there is a solution already in place.  By default the Baicells UE do not request a specific APN.  That causes the EPC to reject the request.

Hi david,

 

If pcap is provided, it is more easier to analyze your problem.

 

BTW, from your log, I've found PDN connectivity reject with ESM_CAUSE:27.

It means that UE APN is unknown in HSS. So, you need to match APN name between UE and HSS.

 

Thanks and regards,

   Sukchan

Does anyone know why I am getting this reject reason for network entry on a UE?

Have you tried to upgrade the firmware of the CPE. I have known baicells
CPE to work better after upgrade. You can use any CPE for your test. Just

Have you tried to upgrade the firmware of the CPE. I have known baicells CPE to work better after upgrade. You can use any CPE for your test. Just to be sure that it's not a CPE issue. I can recommend blinQ and Airspan CPEs

I have used baicells CPE and it got attached having used the default "internet" APN setting .

Hi David,

Baicells CPE has "internet" set as APN by default.

And you can make changes to the APN name under APN management field.

By default the Baicells UE do not request a specific APN.  That causes the EPC to reject the request.

Subject: Connect OCS to PCRF
Message-ID: <CABQDGDYcVtdKwq7SA55qnTn0BqyKrm1EONpZpoT6BC8_am0afQ@mail.gmail.com>

Hi Everyone,

I would like to know if anyone has been able to connect an OCS to open5gs
PCRF. I know OCS talks to the PCRF using the Sy interface and the Gy
interface to connect to the PCEF
Lastly, how do I define these interfaces?

Regards,
