Re: Recording / Re: Regular Osmocom meeting in Berlin?

It was my understanding from your suggestion that there would be presentations and discussions after those presentations at the meetings, making this not just having a beer with friends but more formal affairs. That would be useful for people elsewhere to see, given that this is a global community. Not sure what German law has to do with putting online or streaming such presentations. Cameras off when it comes to the informal part and beer time.. Love this list otherwise. And will come to Berlin this summer so may attend one or two, regardless :) Cheers from New York.

The mere existance of the two words 'camera' and 'unobtrusive' in one sentence are a contradiction in terms. If I want to meet with a small group of people and informally discuss technical topic, than that is _very_ different from being live streamed to an unknonwn number of people, any of which could make recordings and I would have to very carefully think about each and every word that I'm saying. That's not a particularly relaxed environment and would kill all the fun there is in having the meeting in the first place. Legally, In Germany this corresponds to "not publicly spoken word" (nicht oeffentlich gesprochenes Wort). It is punishable under law to record or broadcast that. (Clause 201 of German criminal code).

Could not disagree more. We live-stream local events all the time with a very unobtrusive webcam/ustream and it bothers no one who is there but benefits all who are not.

It kills the local atmosphere without having any real benefit. Every decision/code and most likely slides will be public anyway. z. Sent via mobile. Hence, short.

Regular Osmocom meeting in Berlin?
by Harald Welte 31 Mar '12

31 Mar '12

Hi all, I was pondering to start a regular Osmocom meeting (monthly or bi-weekly) in Berlin. The idea would be not only to converge the existing developers in Berlin (zecke, roh, prom, tobias, peter, kevin, myself, ...) but to also try to share some knowledge and excitement with other interested hackers in the wider community. A split format for the event might make sense: Have a more or less organized 45min talk about one particular topic + 15min discussion and then switch to an informal meeting style without any particular topic or moderator. For the first half there is a long list of topics intended at informing people about the status and capabilities of the respective projects: OsmocomBB, OsmoTETRA, OsmoGMR, SIMtrace, etc. Regarding the venue, I would suggest to hold it at the Berlin CCC. What do you generally think about this? What day of the week should we be aiming at? Tuesday and Thursday is generally not a good idea, as those are already occupied with other events. If you think it's a good idea, I would request/register the event with the CCC Berlin.

Can you record the video about the presentations and upload to some video sharing site ? I'm certain, that there would be some interest watching it :) Thanks, Zsombor On 2012.03.30. 13:33, "Tobias Engel" <t-openbsc(a)tobias.org> wrote: On 29.03.2012 21:41, Peter Stuge wrote: > Harald Welte wrote: >> I was pondering to start a regular ...

Dear Osmocom community, This email to inform you that the call for participation for the next Libre Software Meeting (LSM or RMLL: Rencontres Mondiales du Logiciel Libre) ends on 31st March: http://2012.rmll.info/en/participate/call-for-papers This edition will take place in Geneva from 7th to 12th July 2012 (7-8 general public days, 9-12 theme focused, professional). It would be of great interest for the communities to learn about the Osmocom projects in presentations or workshop. Real world applications would be interesting too. So please don't hesitate to directly submit. Don't hesitate also to contact me for more information. Mathias Coinchon

Question regarding timeouts and RRLP
by Refik Hadzialic 28 Mar '12

28 Mar '12

Dear group members, I would like to ask you a question regarding the timeouts and initiating/allocating an SDCCH channel for a subscriber inside of the GSM network. I am trying to modify some parts of OpenBSC (/openbsc/src/libmsc/rrlp.c) and to implement the MS-based RRLP in OpenBSC (to send assistance data in form of almanac, ephemeris, BTS geolocation data and GPS reference time to the MS). At the moment I use the silent sms to start an RRLP request (send RRLP request + assistance data and then send the silent sms). But if it takes too long to send the assistance data OpenBSC starts from the beginning (send rrlp request + assistance data + sms again). I think this is because OpenBSC waits for an ack from the MS for the silent sms (which has not been sent) and therefore it's a timeout issue. As a quick hack I have modified parts of the code and got the RRLP to work (sent successfully these data and I got a position from the MS). Just for the curious one, I commented out three lines just before the return, in /openbsc/src/libmsc/gsm_04_11.c in the function, gsm411_rx_rp_ack, the following lines: //else //gsm411_release_conn(trans->conn); /* free the transaction here */ //trans_free(trans); and I changed one timer value from 10 to 100, in /openbsc/src/libbsc/bsc_rll.c in the function, rll_establish to: osmo_timer_schedule(&rllr->timer, 100, 0);. As I know what I did was wrong (since changing the timers and not releasing the channel properly influences the whole system) but I just did it for the purpose of testing and to see do I send correct data and does the RRLP work at all. I hope you can give me some hints and guides how to allocate a channel for around 130 seconds and to send the RRLP assistance data within that channel without doing the above tricks. Once everything works properly I will provide the RRLP code. Best regards, Refik Hadzialic

Supplementary Services / Call Waiting in openbsc
by Tobias Engel 22 Mar '12

22 Mar '12

Hi, I pushed the branches tobias/supplementary_services to libosmocore and openbsc repositories. The idea is to enhance openbsc to be able to provide Supplementary Services other than USSD. I tried to implement activation, deactivation and interrogation in a generic way. Registration is not yet implemented, also handling of different teleservices is missing (Everything will be treated as requested for "Telephony"). Call Waiting is now implemented on top of those changes (it is one of the SS that doesn't need registration). (De-)Activation and interrogation can be triggered from the phone using either the menu or the MMI codes *43#, #43# and *#43# (see GSM 02.30). So a call to a subscriber will now only proceed if said subscriber isn't busy or CW has been provisioned and activated. (For details see the commit messages.) I know this isn't the most sexy new feature, but I needed it to test something and maybe somebody wants to implement other supplementary services like call forwarding... -Tobias

(German: "Datensparsamkeit") Following up on this, it seems to me that there is an agreement that we want to record talks where speaker doesn't object against recording. So, I'll try to get a good FullHD camera today and bring it to the conference, but we also need a tripod for a good quality recording. Is there anyone local who could bring one? We don't want to bring one from Moscow. :) -- Regards, Alexander Chemeris. CEO, Fairwaves LLC / ООО УмРадио http://fairwaves.ru
