Dear Osmocom & NextEPC Community,
Today I've added CS Fallback and released NextEPC v0.5.0
So, I'd just like to test this part with Osmocom project, but it seems to
be a difficult task. The reason is why I have little knowledge about 2G/3G.
Nevertheless, I will try to do it
BTW, I don't know if there is anyone who wants to integrate this big thing.
Even though I'm not sure if this will help, but let me introduce the
configuration of the NextEPC.
To use SGsAP, change the mme.conf as follows:
#
# <sgsap>
#
# o Single MSC/VLR
# sgsap:
# addr: 127.0.0.2
# plmn_id:
# mcc: 001
# mnc: 01
# tac: 4130
# lac: 43690
#
# o Multiple MSC/VLR
# sgsap:
# - addr: 127.0.0.2
# plmn_id:
# mcc: 001
# mnc: 01
# tac: 4131
# lac: 43692
# - addr
# - 127.0.0.3
# - fe80::2%lo0
# plmn_id:
# mcc: 001
# mnc: 01
# tac: 4132
# lac: 43692
# - name: msc.open5gs.org
# plmn_id:
# mcc: 001
# mnc: 01
# tac: 4133
# lac: 43693
#
FYI, I also attach the pcap that I run with nextepc simulator as below.
$ ./tests/testcsfb
mo-idle-test : SUCCESS
mt-idle-test : SUCCESS
mo-active-test : SUCCESS
mt-active-test : SUCCESS
All tests passed.
Feel free to raise any questions about this things.

I advise you to not spend too much time on it until we can provide you
with a set of configuration and instructions on how to configure this,
instead of spending a lot of time in trial and error. I think we can
save you some time there.
A good starting point would be to use the nightly builds for Ubuntu or Debian,
(see https://osmocom.org/projects/cellular-infrastructure/wiki/Nightly_Builds)
and try to follow the general instructions of
https://osmocom.org/projects/cellular-infrastructure/wiki/Osmocom_Network_I…. The
goal would be to create a network with two phones/IMSIs
where you can have a 2G-to-2G voice call first. Only once that works, the
LTE neighbor cell information and SGs configuration can be added.
You will need the following parts for a minimal 2G setup:
* osmo-trx + osmo-bts-trx (if using SDR like B2x0)
* osmo-bsc (RR)
* osmo-msc (MM + CC)
* osmo-hlr
* osmo-stp (for SS7/SIGTRAN between BSC and MSC)
* osmo-mgw (for RTP audio streams; one instance can be shared between BSC and MSC)
All of the above can run on a single machine
BTW, I don't know if there is anyone who wants to
integrate this big thing.
For sure we want to, and we also know there are users out there who want to.
Even though I'm not sure if this will help, but
let me introduce the
configuration of the NextEPC.
Thanks, this is useful. We'll try to to set this up accordingly, but it may
take some time.
Philipp (Cc) has been developing most of the SGs interface on the Osmocom
side, he can help you (here on this list and by direct e-mail) with any related
issues.
FYI, I also attach the pcap that I run with nextepc
simulator as below.
Thanks, I'd like to ask Philipp to review this and report if it reflects his
expectations about the SGs interface procedures.
btw/unrelated: I've been hacking a lot on TTCN-3 tests for the MME, and
I've managed to get the way into NAS (EMM/ESM) and am getting all the
way up to a Attach Reject (see attached pcap). As I'm only simulating
S1AP and SGsAP so far (and not diameter), it's expected that the attach
will be rejected. I guess I'll start with using nextepc-hss first, and
add diameter support to the tests only in a later step.
Regards,
Harald

Rhizomatica is very much interested in testing such setup with CS voice
fallback for LTE to GSM.

Sorry, please find it attached. It's not much, but it shows that the basic
S1AP and NAS infrastructure for emulating eNB and UE works. I sill have
to write quite a bit of code to actually perform the authentication

Hello Sukchan and friends.
I'm trying to use the CSFB in test lab, and every time that nextepc send
the UEContextModificationRequest, the UE respond with an
UEContextModificationFaliure [ Protocol-cause=semantic-error ].

I'm looking why I'm getting this. Someone have any idea?

Hi all,
I'd also like to test SMS and CSFB in LTE. I have some experience with
the Osmocom GSM stack, but not much with the NextEPC LTE. Could you
point me which fields should I set in the configuration files?
Thanks,

Hello Rafael
I just configure the NextEPC to connect via SGS to OSMO-MSC, like this:
sgsap:
addr: 127.0.0.1
port: 29118
name: vlr.example.net
tai:
plmn_id:
mcc: 724
mnc: 21
tac: 12345
lai:
plmn_id:
mcc: 724
mnc: 4
lac: 51544
And the configuration in the MSC:
sgs
local-port 29118
local-ip 0.0.0.0
vlr-name vlr.example.net
And configure the IMSI in the Osmo-HLR and NextEPC-HSS
If you need more help tell me.
Thanks

Hi Rafael,
In the NextEPC, there are two ways to specify peers. 'addr' sets the IP
address, and 'name' sets the hostname.
So, if your network is configured to look up the VLR as a hostname, you can
use 'name'.
'port' was just made for testing. If you want to use a different port
without using standard 29118, you can put 'port' number.
By the way, I've changed how to configure CS Fallback & SMS as below.
# o Single MSC/VLR(127.0.0.2)
