Hi all, After buying a super Sim Kit (16 in 1) from China, I tried the reader (green PCB inside a blue transparent plastic case with a blue LED) and SIM (identified as a fakesupersim) with pysim tool. However i am getting the following error: /pySim-prog.py -n 26C3 -c 49 -x 262 -y 42 -z 1234 -j 1 -t auto Insert card now (or CTRL-C to cancel) Autodetected card type fakemagicsim Generated card parameters : > Name : 26C3 > SMSP : e1ffffffffffffffffffffffff058100945555ffffffffffff000000 > ICCID : 8949262427518313026 > MCC/MNC : 262/42 > IMSI : 262422461512085 > Ki : 7b74741a1ee14337ec23f9ab92a13648 > OPC : ccd867d60797d8d45354a51b3ef568ff Programming ...

Also I have tried forcing different models of SIM, but nothing is working. Obviously I can remove this check from the script file (__init__.py in /pySim/transport), however somebody had a reason to put such condition there. I would like to ask if it is safe to remove that line of code and the purpose of that line of code. Thanks a lot and best regards Martin

Re: Help with sccp library

by mosbah abdelkader

> I don't understand. This callback will be called with data you need to write > to the network. In case of MTP Level3 you will need to wrap that around the > msgb you got. I means: is the interaction with mtp3 layer implemented (is sending sccp data by mtp3 implemented by the library?)? Also, what about the reception of data from mtp3 layer. is that implemented in the sccp lib. I am asking these questions because I see the code of mtp3 in the lib but no significant call is present in the sccp part of the lib. Thank you for your help.

Re: Any interest for Osmocom meetings in Bavaria ?

by Dieter Spaar

So far three persons have indicated their interest to join a meeting at my place. Considering the time it takes to drive to my place, it probably makes sense to have the meeting at the weekend (either Saturday or Sunday) so that there is more time for the meeting itself. I can suggest one of the following dates for the first meeting, somewhere between 10:00 to 18:00 on each day: 25.8. (Sa) or 26.8. (Su) 1.9. (Sa) or 2.9. (Su) 8.9. (Sa) or 9.9. (Su) So please let me know when you have time and also make suggestions in which Osmocom topic you are interested in so that we can have some sort of agenda for the meeting to make best use of the time. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

SimpleHLR: A web interface for OpenBSC

by Peter Caprioli

Hello everyone, I've just finnished writing together a small web interface for the OpenBSC HLR. It allows you to modify various parameters in the database and also provides a set of functions to modify the HLR or sending SMSes in your own scripts. The project is still very alpha but it seems to work reasonably good. Feel free to give any feedback! Screenshots and source code is available on my website: https://stormhub.org/simplehlr/ -- *Best regards, Peter Caprioli*

Testing Openbsc without a BTS

by Priyanka Behl

Hi everyone, I am trying to test Openbsc without a BTS. I need your help as I am very new to Openbsc. After doing the configurations for openbsc-multitrx.cfg file this is how I started the process: cd openbsc/openbsc src/osmo-nitb -c doc/examples/osmo-nitb/nanobts/openbsc-multitrx.cfg -C And the output I received was: <0019> input/ipaccess.c:925 enabling ipaccess BSC mode DB: Database initialized. DB: Database prepared. <0001d> sms_queue.c:220 Attempting to send 20 SMS After this I added a subscriber in the hlr and the subscriber was added in the output: <0019> ipaccess.c:841 enabling ipaccess BSC mode DB: Database initialized. DB: Database prepared. <001d> sms_queue.c:232 Attempting to send 20 SMS <0002> gsm_subsciber.c:390 Expiring inactive subscriber Testing(ID 1) After this I used the following commands on the osmo-nitb console and receive the following output: Openbsc>show subscrber id 1 ID: 1, Authorized: 1 Name: 'Testing' Extension: 9999999999 LAC: 0/0x0 IMSI: 404012345678903 TMSI: 0012D681 Pending: 0 Usecount: 1 Openbsc> subscriber id 1 send sms Hello Openbsc> subscriber id 1 silent call start any %subscriber not attached Am I doing the right thing, are there some more configurations that I am required to do and is this the only output that can be achieved without a BTS? Also the lac is being displayed as 0/0x0, is this how it should have been? Please let me know, I really need help on this. Thanks and regards Priyanka
