Dear List,
I tried to set up Osmo-CBC with a Nokia MetroSite BTS according to the
wiki. But every time the CBSP clinet of the BSC connects to the CBC
server, the BSC log indicates:
DCBS cbsp_link.c:150 CBSP Client connected to CBC:
(r=127.0.0.1:48049<->l=127.0.0.1:46133)
DCBS smscb.c:805 (bts=0) Rx CBSP RESET: clearing all state; disabling broadcast
Same time on the CBC:
<0002> cbsp_link.c:265 New CBSP link connection from 127.0.0.1:46133
<0002> cbsp_link_fsm.c:181 local-bsc: RESTART (CBS) but re-sending not
implemented yet
The BTS is configured with CCCH+SDCCH4+CBCH, and these are the
relevant sections:
osmo-cbc.cfg:
cbc
unknown-peers reject
ecbe
local-ip 127.0.0.1
local-port 12345
cbsp
local-ip 127.0.0.1
local-port 48049
sbcap
local-ip 127.0.0.1
local-port 29168
peer cbsp local-bsc
mode server
remote-port 46133
remote-ip 127.0.0.1
osmo-bsc.cfg:
cbc
mode client
client
remote-ip 127.0.0.1
local-ip 127.0.0.1
local-port 46133
Every other CS service is working fine on the BTS.
Is there anything else I might have missed?
Regards,
Csaba

Hi Sipos,
I fail to see which is exactly the problem you have.
Can you describe what you expect instead of what you are getting?
Regards,
Pau

Hi Pau,
When I use the command:
./cbc-apitool.py create-cbs --msg-id 4370 --payload-data-utf8 "Bon giorno!"
Nothing happens. I thought the issue is with the link between the CBC
and the BSC due to this message in the logs.
The phone has a CBC app which is running, but nothing is displayed.

Hi,
"nothing happens" is a bit too vague.
Can you at least share a pcap file ?

Hi,
I cant share a pcap atm, but I enabled debugging for RSL and CBS, and
this is how that looks:
Tue Sep 26 11:52:32 2023 DCBS cbsp_link.c:150 CBSP Client connected to
CBC: (r=127.0.0.1:48049<->l=127.0.0.1:46133)
Tue Sep 26 11:52:32 2023 DCBS cbsp_link.c:193 Received CBSP RESET
Tue Sep 26 11:52:32 2023 DCBS smscb.c:973 CBSP Rx RESET
Tue Sep 26 11:52:32 2023 DCBS smscb.c:805 (bts=0) Rx CBSP RESET:
clearing all state; disabling broadcast
Tue Sep 26 11:52:32 2023 DCBS smscb.c:211 (bts=0) Success
Tue Sep 26 11:52:43 2023 DCBS cbsp_link.c:193 Received CBSP WRITE-REPLACE
Tue Sep 26 11:52:43 2023 DCBS smscb.c:860 CBSP Rx WRITE_REPLACE (CBS)
Tue Sep 26 11:52:43 2023 DCBS smscb.c:681 (bts=0) BASIC Added
MsgId=0x1112/SerialNr=0x7000/Pages=1/Period=5/NumBcastReq=999
Tue Sep 26 11:52:43 2023 DCBS smscb.c:211 (bts=0) Success
after this on RSL only "Rx Resource Indication" messages, and CBSP keep alives.
Based on this I would say the Osmo-CBC does sends the message to the
BSC, and nothing happens between the BSC and the BTS.

Csaba

The log looks fine.
If you look at the RSL from BSC to BTS you should see the related smscb sent to the bts.
