Neels Hofmeyr nhofmeyr at sysmocom.deSome code that is disabled to be able to compile libmsc without libbsc is related to communication to the BTS, that is replaced by the new A-interface. However, the following bits are not; Any opinions about what to do with it: - Report on which ARFCN and timeslot a silent call has occured. I would simply drop the ARFCN and timeslot information, saying "silent call successful". (same in two log messages) static int scall_cbfn(unsigned int subsys, unsigned int signal, void *handler_data, void *signal_data) { struct scall_signal_data *sigdata = signal_data; struct vty *vty = sigdata->data; switch (signal) { case S_SCALL_SUCCESS: vty_out(vty, "%% silent call on ARFCN %u timeslot %u%s", sigdata->conn->lchan->ts->trx->arfcn, sigdata->conn->lchan->ts->nr, VTY_NEWLINE); break; case S_SCALL_EXPIRED: vty_out(vty, "%% silent call expired paging%s", VTY_NEWLINE); break; } return 0; } - Add Osmocom specific TLVs to SMPP /* Append the Osmocom vendor-specific additional TLVs to a SMPP msg */ static void append_osmo_tlvs(tlv_t **req_tlv, const struct gsm_lchan *lchan) { int idx = calc_initial_idx(ARRAY_SIZE(lchan->meas_rep), lchan->meas_rep_idx, 1); const struct gsm_meas_rep *mr = &lchan->meas_rep[idx]; const struct gsm_meas_rep_unidir *ul_meas = &mr->ul; const struct gsm_meas_rep_unidir *dl_meas = &mr->dl; /* Osmocom vendor-specific SMPP34 extensions */ append_tlv_u16(req_tlv, TLVID_osmo_arfcn, lchan->ts->trx->arfcn); if (mr->flags & MEAS_REP_F_MS_L1) { uint8_t ms_dbm; append_tlv_u8(req_tlv, TLVID_osmo_ta, mr->ms_l1.ta); ms_dbm = ms_pwr_dbm(lchan->ts->trx->bts->band, mr->ms_l1.pwr); append_tlv_u8(req_tlv, TLVID_osmo_ms_l1_txpwr, ms_dbm); } else if (mr->flags & MEAS_REP_F_MS_TO) /* Save Timing Offset field = MS Timing Offset + 63 */ append_tlv_u8(req_tlv, TLVID_osmo_ta, mr->ms_timing_offset + 63); append_tlv_u16(req_tlv, TLVID_osmo_rxlev_ul, rxlev2dbm(ul_meas->full.rx_lev)); append_tlv_u8(req_tlv, TLVID_osmo_rxqual_ul, ul_meas->full.rx_qual); if (mr->flags & MEAS_REP_F_DL_VALID) { append_tlv_u16(req_tlv, TLVID_osmo_rxlev_dl, rxlev2dbm(dl_meas->full.rx_lev)); append_tlv_u8(req_tlv, TLVID_osmo_rxqual_dl, dl_meas->full.rx_qual); } if (lchan->conn && lchan->conn->vsub) { struct vlr_subscr *vsub = lchan->conn->vsub; size_t imei_len = strlen(vsub->imei); if (imei_len) append_tlv(req_tlv, TLVID_osmo_imei, (uint8_t *)vsub->imei, imei_len+1); } } deliver_to_esme() { [...] if (esme->acl && esme->acl->osmocom_ext && conn->lchan) append_osmo_tlvs(&deliver.tlv, conn->lchan); [...] } - Siemens BS11 MRPCI /* see mail on openbsc@ 9 Feb 2016 22:30:15 +0100 * We need to hook sending of MRPCI to Siemens BS11 somewhere else */ if (is_siemens_bts(conn->bts)) send_siemens_mrpci(msg->lchan, classmark2-1); - Debug log: report bts - trx - ts - ti in mncc_rcvmsg() (No BTS information available in OsmoMSC anymore) - In gsm48_cc_rx_setup(), populate struct gsm_mncc setup with lchan type. (lchan information is no longer available in OsmoMSC) - In libmsc, gsm_04_08.c, we connect libbsc handle_abisip_signal(); the same is done in osmo_bsc_audio.c in osmo_bsc_audio_init(), so I assume it can be dropped from libmsc. /* * This will be run by the linker when loading the DSO. We use it to * do system initialization, e.g. registration of signal handlers. */ static __attribute__((constructor)) void on_dso_load_0408(void) { osmo_signal_register_handler(SS_ABISIP, handle_abisip_signal, NULL); } ~N -------------- next part -------------- A non-text attachment was scrubbed...
