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 <http://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 <http://vlr.example.net>
And configure the IMSI in the Osmo-HLR and NextEPC-HSS
If you need more help tell me.
Thanks
Romeu Medeiros

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,
Rafael Diniz

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?
Thanks

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 <http://msc.open5gs.org>
<http://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.
