Hello! I Need Help
I install these three programs OpenBTS, OsmocomBB, Asterisk
Then run them, Everything works well
OpenBTS sent an SMS to my phones
I answered and he checked me
I registered into OpenBTS a second phone
I tried to transfer SMS between phones - all good
but when I try to call from one to another I did not get
Asterisk writes
================================================================
*CLI> Retransmission timeout reached on transmission 755803415(a)127.0.0.1 for
seqno 179 (Critical Response) -- See
wiki.asterisk.org/wiki/display/AST/SIP+Retransmissions
Packet timed out after 32001ms with no response
================================================================
Why?
What do I do?

Hey there, I bumped into this error when testing gprsdecode from srldabs.de When I try the sample .dat files provided from srlabs.de it works fine though. Any hints?
Kind Regards

Hey, I finally watched Nico's talk "let me answer that for you" and heard him say he ported layer2/3 to target.
Also found a mailing list message about him cleaning it up and putting it up on git and sending it to a few folks.
Did that code ever get shared? Would be cool to play around with and is certainly something I would eventually want to accomplish for my project of making a phone that works by itself.

Dear all, I vae the C115 with a T1 USB to Serial cable with the Prolific
chipset.
When i run osmocon i get :- an its just sits there with no further
processing.

I think the cable is ok as when i run my fingers on the tip i get random
Zeros so it appears to be talking to the cable.
Also when i tried to run Mobile i get the :- even though i created the
Mobile.cfg file in /etc/osmoco
Failed to parse the config file: '/home/raz/.osmocom/bb/mobile.cfg'
Please check or create config file using: 'touch
/home/raz/.osmocom/bb/mobile.cfg'
I have spent some hours researching the lists and trying various things to
no avail but I want to continue until I resolve this issues and use this
great stack to learn about the GSM network.
Please advise.
Great full for any help or pointers but this maybe a timing issue that is
difficult to debug.
Thanks

hi,
i did a lot of resarch and testing on cell selection and re-selection
process the last two week.
the cell selection process, network selection process (manual and
automatic) and mobility management process were already implemented in
OsmocomBB a long time, but turned out to be buggy and incomplete. i made
test drives to check the process and debugged it.
the re-selection process is new. it is used to track surrounding cells
while listening to the BCCH of the current cell (camping on a cell).
special extension to the layer1 firmare is used to measure neighbour
cells. if an neighbour cell becomes 'better', the mobile switches to
that cell, depening on different criteria. now it is possible to move
with OsmocomBB.
the re-selection process is not handover! handover is a process where a
phone switches between cells while doing a call. handover is one next
step to implement. the process is a little more complex, because it
requires not only neighbour cell measurements, but also syncing to them
without interrupting the traffic channel. most layer 3 stuff of handover
is already implemented.
if you like to play and test your moving OsmocomBB, you can check out
the "jolly/roaming" branch. it contains the extension to layer1, as well
as sim reader and fixes from "sylvain/testing" branch. use both "mobile"
and "layer1" firmware from this branch.
in order to see some process at VTY, you can do:
enable
monitor network 1 (continously display the strongest cell and neighbour
cells)
show ms 1 (to see current states)
show neighbour-cells 1 (to see a more detailed current list of
neighbours)

Hi,
in the osmocom bb mobile.cfg I don't see any posibility to set a fixed
Kc encryption key and the tmsi.
How could I achieve that osmocom uses my defined Kc and tmsi?
cheers,
Simian

Hi there,
I am sorry to bother you but I am really confused by recent experiment.
When I was doing the GSM sniffing I found that some of sms messages that
were sent continuesly were missing, I can only capture 50-60% of all test
messages. By analyzing wireshark data I found that osmocom program keeps
tracking packets(lapdm) once an Immediate Assignment captured and if at the
same time there comes another Immediate Assignment the program will miss
it.I think this is the reason why i lost some messages.So is there any
suggestions I can fix this up? Like using a backup phone to capture the
second Immediate Assignment during one period?
Thanks,
Swift

Without Filter Replacement can i use motorola c115 for OpenBTS?
or by just loading highram firmware can i able to get sms sent on any
networks and see them in wireshark?
P.S help required
Hello sir,
I'm from India, there is no encryption used, I used rtl sdr. In Kali Linux
successfully, but here hopping frequencies are used, so I want to try
osmocom, I did some search regarding this,but can you give me instructions
in steps to get GSM SMS sir.
Regards
HARI

Hello list,
I'm playing with the mobile application of OsmocomBB. I have two SIM
cards of
two different operators. Everything works fine with one of them, but it
doesn't
with the other one.
Layer1 hangs there:
SIM Request (7): a0 a4 00 00 02 6f 30
SIM Response (2): 9f 0f
SIM Request (5): a0 c0 00 00 0f
SIM Response (17): 00 00 00 f6 6f 30 04 00 11 ff ff 01 02 00 00 90 00
SIM Request (5): a0 b0 00 00 f6
and mobile hangs there:
<0005> subscriber.c:600 Requesting SIM file 0x6f30
<000f> sim.c:209 got new job: SIM_JOB_READ_BINARY (handle=00000004)
<000f> sim.c:241 SELECT (file=0x6f30)
<000f> sim.c:187 sending APDU (class 0xa0, ins 0xa4)
<000f> sim.c:876 received APDU (len=0 sw1=0x9f sw2=0x0f)
<000f> sim.c:949 command successfull
<000f> sim.c:571 GET RESPONSE (len=15)
<000f> sim.c:187 sending APDU (class 0xa0, ins 0xc0)
<000f> sim.c:876 received APDU (len=15 sw1=0x90 sw2=0x00)
<000f> sim.c:949 command successfull
<000f> sim.c:1065 selected file (len 246)
<000f> sim.c:277 READ BINARY (offset=0 len=246)
<000f> sim.c:187 sending APDU (class 0xa0, ins 0xb0)
So, as I understand it, it tries to read the PLMN selectors from SIM but
does
not get any answer and the callback function is not called.
Also, when using the command "off", everything shuts down with the first
SIM,
but I have to use ctrl-c for the second one after mobile hangs here:
<000f> sim.c:1234 exit SIM client
I have the last versions of libosmocore and osmocom-bb in the master
branch,
and I enabled TX support. I also tried to set my IMEI in the mobile.cfg
file
but this does not change anything. The config file is joined as well.
Did I forget something? Do you have an idea?
Thank you!

Hello list,
I'm playing with the mobile application of OsmocomBB. I have two SIM
cards of
two different operators. Everything works fine with one of them, as you
can see
in the mobile_ok log, but it doesn't with the other one, as you can see

Layer1 hangs there:
SIM Request (5): a0 b0 00 00 f6
and mobile hangs there:
<000f> sim.c:1065 selected file (len 246)
<000f> sim.c:277 READ BINARY (offset=0 len=246)

Then nothing happens.
Also, when using the command "off", everything shuts down with the first

but I have to use ctrl-c for the second one after mobile hangs here:
<000f> sim.c:1234 exit SIM client
