running voice data/encryption on compal?

by Aaron Zauner

hi, a while ago i've read that someone managed to have an active phone call over osmocom for about 20mins. i woundered if it is theoretically & technically possible to have an active, serious (thus not a5) encryption running for voice or data calls on the stack? thanks in advance & greetings from vienna ;) azet

[PATCH libosmocore] gsm 03.41: fix GSM341_MSG_CODE macro argument

by Alex Badea

One usage of the "ms" argument is typoed as "msg". Fix it to prevent subtle future failures. Also paranthesize the macro argument for good measure.

open cell phone hardware questions

by Scott Weisman

Hi everyone. I'm admittedly more a lurker than an active participant in this project. I find it very fascinating and regard its objectives as important. I recently watched several of the C3 presentations, from this and previous years. Having open, documented hardware and software seems to be an important goal in itself. Just knowing about all the potential weaknesses in the software stacks of most phones, as well as hidden "features" like SMS messages that could, theoretically, do things like remotely enable the phone mic, among other things (things that are certainly technically possible, and also due to the closed nature of the software, completely unknown) are of grave concern to me. Now, given that the supported phone hardware is old and not reliably available, I was wondering if anyone knows if the Calypso and other chips in these old phones are still available for new designs? How much interest would there be, say, in an open, but VERY SIMPLE, actual phone? Kind of like the Pandora project, but without the ambition to make the most advanced portable game player possible. The Osmocom software would then be very easily portable to such a device. Given the seemingly widespread interest and enthusiasm for the Osmocom, OpenBTS, and OpenBSC projects, a real, genuinely open phone (not a pseudo-open phone like the FreeRunner) might possibly have enough interest, and be buildable for a low-enough cost, to merit further discussion. Anyone want to discuss this?

TODO: OsmocomBB to continually iterate over all cells and dump SI

by Harald Welte

Hi! A number of people want to do some long-term evaluation of their cellular environment and would be interested in an 'app' for OsmocomBB that continuously scans the spectrum and dumps the cell parameters such as * ARFCN, Signal Level, SNR * frequency synch offset * SCH info (BCC/NCC) * SI (at least 1-4) from BCCH I would love to do it, but I simply don't have the time. I thought maybe somebody on this list is looking for a relatively simple task and has some time. I think this is a great project to work with OsmocomBB without having to go into the details. The algorithm would look something like STATE 1: Power Scan * do power measurement over all supported bands * pick strongest N carriers and iterate over them STATE 2: FCCH/SCH acquisition * try to get lock on the carrier * if not, go back to next carrier from power scan * if yes, continue with STATE 3 STATE 3: Wait until all relevant SI have been received * generate GSMTAP output for the SI messages (or timeout) * go back to STATE 2 for next strongest ARFCN * after last ARFCN, re-start from STATE 1 This is basically the initial step of the GSM 03.22 cell (re)selection that we already have as part of the 'mobile' program. So all the code is there, but what's needed is a separate rady-made app, not requiring any user interaction. It should also include some e.g. shell script that automatically generates a new pcap file every N minutes/hours, and make sure to never overwrite any existing PCAP file. In the end, having this running for an extended period of time should simply produce a large number of PCAP files without any manual interaction. Lock-ups in any state should be detected by timers, singalling a proper L1_RESET to make sure it continues. Unplugging / re-plugging the phone should also not require any re-start of the program. Optional extensions: * software to aggregate info from the pcap files (remove duplicate entries, e.g.) * optional logging of GPS coordinates from a GPS receiver If anyone has some time to give this some work, I'd most appreciate it. Please inform the mailing list to ensure no duplicate work is created.

by SoftwareRadioGuy

Everyone, Is it true you can use a MTK Chipset as a DIY GSM BTS/USRP ? I've emailed this fellow who posted this back in December 2010 but have gotten no reply to date. This would be excellent for use on something I'm working on in Africa for about 50 - 100 IMPOVERISHED villages. Awaiting anyone's input on this.

OSX build

by MATTHEW EVANS

Hi All, I'm really struggling to get the latest source to build on OSX. Would anyone be kind enough to offer some assistance to getting this compiled? Build fails with: ./configure: line 3461: syntax error near unexpected token `LIBOSMOCORE,' ./configure: line 3461: `PKG_CHECK_MODULES(LIBOSMOCORE, libosmocore)' Any help or advice would be appreciated! Many Thanks, Matt.

C123: reading SIM stuck

by Frank Rosengart

Hi, just for curiosity, I would like to get the osmocomBB running on the Motorola C123. Everything works fine (radio starts scanning for networks) if I use the test SIM feature. But reading a real SIM plugged into the phone does not work for me. The 'mobile' app shows: <0004> subscriber.c:556 Requesting SIM file 0x2fe2 <000e> sim.c:209 got new job: SIM_JOB_READ_BINARY (handle=00000004) <000e> sim.c:697 go MF <000e> sim.c:241 SELECT (file=0x3f00) <000e> sim.c:187 sending APDU (class 0xa0, ins 0xa4) -end- Any hints where to start debugging? (does neither work with 3 different SIMs: swisscom, blau, super-sim) BTW: Are there any plans to support external SIM readers via PC/SC etc.? Thanks Frank

GSM Codes with Osmocombb

by Tim Ehlers

Hi, I'm playing around with Osmocom for a while now. My final goal is to use it as a stationary phone on a PC to be able to remotly control the phone. I checked out the sylvain/testing tree, to use my SIM card and managed to be able to make and receive calls. Very amazing so far. :-) Now I tried to send GSM codes (like *#21#, oder *21*{NUMBER}#) to set and unset call diverts. It seems, that "call 1 *21*{NUMBER}#" does not work. Normal GSM cellphones seem to handle these codes not as a normal call. Does anybody know how one could send GSM codes to the network? Thanks Tim
