Hi, Sylvain Munaut It's china mobile, i can provide more information if you need. Thanks for pointing out the right way, i'll try to modify codes according to BCCH'. BTW, i modify TS (line l1s_rx_win_ctrl _ONLY_) from 0 to 2, 4 and 6, the TS2 and TS4 work well, but the TS6 crash very soon because FCCH error, for example, what's wrong? (high TS -> low TS)?

About sniff multi bursts in a frame, CCCH_CONF
by Aegean Chou 26 Sep '11

26 Sep '11

Dear all, the bts arround me uses MultiCCCH, it's CCCH_CONF = 110 (6), so it uses TS0, TS2, TS4 and TS6 in a frame for PCH/AGCH. but the burst_ind only CCCH-CONF 0 & 1 are supported, it can sniff TS0 only, so only catch 1/4 IMM ASS for me. my OWN phone, it's just not in TS0 (i use nokia netmonitor to check it), so i can't catch it at all (phones use IMSI to decide page group). i read the source briefly, and modify prim_rx_nb.c line "l1s_rx_win_ctrl(arfcn, L1_RXWIN_NB, 0);" for TS2, TS4, TS6 temporarily, but this way i'll need 4 phones to catch ONE station. it's very strange, and not beauty. i think the bottleneck is the DSP, as the DSP task (ALLC_DSP_TASK) can only process one TS of a frame (it's enough for phone), i think maybe backup/restore the DSP task variable patch needed, i'm new to the DSP disassemble and patch, anyone can help? thanks Best Regards Steve

Proposed patch for libosmocore/gsmtap
by iZsh 23 Sep '11

23 Sep '11

Please find attached a proposed patch for libosmocore The modifications are needed if we want to be able to send a gsmtap packet with a type different than GSMTAP_TYPE_UM. It's a fairly straightforward patch. Best Regards, iZsh

what about femtocells?
by Sébastien Lorquet 22 Sep '11

22 Sep '11

Hi all, Do you see any interest in the domain of femtocells? this model, that will be sold in France, claims to be pluggable (probably via ethernet) into nearly any ISP provided home router (internet "box"). http://www.pcinpact.com/actu/news/65810-sfr-mobile-adsl-3g-femto.htm Is it in any way comparable to the nanoBTS and other stuff you're hacking nowadays ?

GSM 850 / PCS 1900 : PLEASE HELP NEEDED
by rola 21 Sep '11

21 Sep '11

Hi All, I have done all what I could in setting up the project and running of it as indicated in the wiki and mailing list. It has been over two weeks of trial and error of figuring out of what the problem is that led me to this conclusion that OsmocomBB project might not be designed optimally for US GSM Bands (GSM 850/ PCS 1900). The system could not get synchronised to a frequency when FSBS request is carried out. I read from the mailing-list about the possible modification to be done on the file rffe_dualband.c for GSM band in US in order to resolve the issue of synchronisation. I made a changed of DCS 1800 to PCS 1900 and yet the output remain the same with no difference. Perhaps, I am still overlooking a possible detail that might make the MS not synchronising. However the power measure is of average -90dBm which I think might be too low for required level. If there can be anyone with any clue to resolve or shed more light on this issue I am kindly requesting for assistance I have my configuration and output as followed: SYSTEM CONFIGURATION: OS : Ubuntu 10.10 Maverick Meerkat TI- Calypso: Motorola C155 (US Model) Cable: PL2303 USB cable Tool-chain: Self compiled GNUArm tool-chain based on instruction on http://bb.osmocom.org/trac/wiki/GnuArmToolchain OsmocomBB Branch: Successful installation of both Master and Sylvain branch with modification to Makefile to enable transmitting PROGRAM OUTPUTS: Running OsmocomBB (Sylvain Branch) Osmocon Output 1 : rola@amira:~/test2-osmocom-bb/osmocom-bb/src/host/osmocon$ ./osmocon -p /dev/ttyUSB0 -m c155 ../../target/firmware/board/compal_e99/layer1.compalram.bin got 1 bytes from modem, data looks like: 00 . got 6 bytes from modem, data looks like: 1b f6 02 00 41 01 ....A. got 1 bytes from modem, data looks like: 40 @ Received PROMPT1 from phone, responding with CMD read_file(../../target/firmware/board/compal_e99/layer1.compalram.bin): file_size=53804, hdr_len=4, dnload_len=53811 got 1 bytes from modem, data looks like: 1b . got 1 bytes from modem, data looks like: f6 . got 1 bytes from modem, data looks like: 02 . got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 41 A got 1 bytes from modem, data looks like: 02 . got 1 bytes from modem, data looks like: 43 C Received PROMPT2 from phone, starting download handle_write(): 4096 bytes (4096/53811) handle_write(): 4096 bytes (8192/53811) handle_write(): 4096 bytes (12288/53811) handle_write(): 4096 bytes (16384/53811) handle_write(): 4096 bytes (20480/53811) handle_write(): 4096 bytes (24576/53811) handle_write(): 4096 bytes (28672/53811) handle_write(): 4096 bytes (32768/53811) handle_write(): 4096 bytes (36864/53811) handle_write(): 4096 bytes (40960/53811) handle_write(): 4096 bytes (45056/53811) handle_write(): 4096 bytes (49152/53811) handle_write(): 4096 bytes (53248/53811) handle_write(): 563 bytes (53811/53811) handle_write(): finished got 1 bytes from modem, data looks like: 1b . got 1 bytes from modem, data looks like: f6 . got 1 bytes from modem, data looks like: 02 . got 1 bytes from modem, data looks like: 00 . got 1 bytes from modem, data looks like: 41 A got 1 bytes from modem, data looks like: 03 . got 1 bytes from modem, data looks like: 42 B Received DOWNLOAD ACK from phone, your code is running now!

Architecture of oscomBB
by nghia phan 18 Sep '11

18 Sep '11

Hello everyone, I'm new to OscomBB and have few questions about its architecture. I have ordered the C123 and the serial cable. Note: I have OpenBTS running quite well and would like now to explore the other end. I did look at the Software Overview page and have the following questions: a/ where can I log the raw burst (156 bits)? [ not the IQ samples ] on the PC? on the ARM7? b/ on the downllink path, how is the FCH detection process split between dsp, arm7 and PC? ie from raw burst to FCH detection indication and offset value. c/ on the downllink path, how is the SCH decode process split between dsp, arm7 and PC? ie from raw burst to GSM frame number, BSIC etc.. d/ on the downllink path, how is the BCCH decode process split between dsp, arm7 and PC? ie from raw burst to System Informations... d/ on the uplink path, how the RACH encode process (RACH_REQ) is split between dsp, arm7 and PC? Thank your for your kind answers. Rgds Nghia

RFC: libosmocore generic CRC
by Sylvain Munaut 17 Sep '11

17 Sep '11

Hi, I've just pused in libosmocore a branch sylvain/crc with a proposal for some generic CRC function. The goal here is to provide a base implementation so that channel coding/decoding of the various other projects can use this as a base rather than reimplement their own for each poly. The API is targeted towards that use (using array of ubit_t rather than a buffer of packed bits). The code is generated from a template and expanded into a 8 / 16 / 32 / 64 bits version by the Makefile (each capable of supporting any crc length inferior or equal to that. So a CRC12 would use the 16bits state function). Appropriate doxygen doc is included. If nobody has objection / comments / ... I'll go ahead and merge it. Cheers, Sylvain
