Not able to see measurement reports in wireshark
by Mehrin Javed 21 Mar '13

21 Mar '13

Dear all, I have successfully made a call from the master branch of Osmocom-bb . After integrating it to wireshark, I am able to see system information 5 and 6 but I am unable to see the measurement reports and voice traffic. Following is what i am able to see when i execute the mobile application . There are valid measurement reports being generated , but why cant i view them in wireshark.? Looking forwards to your response as soon as possible.

Sharp drop in SNR during TCH
by Bhaskar11 21 Mar '13

21 Mar '13

Dear Sylvain, I'm studying traffic data using ccch_scan in burstind branch. In prim_sniff.c I track the SNR levels in l1s_sniff_resp() using code from print_tch.c to read snr values from: dsp_api.db_r->a_serv_demod[D_SNR]; I find that the level changes sharply from ccch mode to tch mode. In ccch mode most of the snr values are 16384. After switching to tch mode they range from 200 to 600 typically! Is this normal? Am I doing something wrong when changing mode? Below is the dump of snr values and freq_err during the run. B. =============== data dump fnx = fn % 26; freq_err = ANGLE_TO_FREQ(dsp_api.db_r->a_serv_demod[D_ANGLE]); snr = dsp_api.db_r->a_serv_demod[D_SNR]; fnx=6, bidx=0, freq_err=-24, snr=16384.

Decoding SDCCH
by Akib Sayyed 12 Mar '13

12 Mar '13

Dear List I am trying to decode SDCCH. but I am not able to do it properly. Here is part of burst_ind app_ccch.c code. if (rv == 0) { uint8_t chan_type, chan_ts, chan_ss; uint8_t gsmtap_chan_type; struct osmo_phsap_prim pp; /* Send to GSMTAP */ rsl_dec_chan_nr(bi->chan_nr, &chan_type, &chan_ss, &chan_ts); gsmtap_chan_type = chantype_rsl2gsmtap( chan_type, bi->flags & BI_FLG_SACCH ? 0x40 : 0x00 ); gsmtap_send(gsmtap_inst, arfcn, chan_ts, gsmtap_chan_type, chan_ss, ntohl(bi->frame_nr), bi->rx_level, bi->snr, l2, sizeof(l2) ); here l2 is 23 byte. I need to remove send it to lapdm to decode it further then will pass it to RR. Please help me in using Lapdm for decoding :) -- Akib Sayyed Matrix-Shell akibsayyed(a)gmail.com akibsayyed(a)matrixshell.com Mob:- +91-966-514-2243
