Another Compile Error

by Stuart Baggs

Hi guys, I am trying to get openBSC to compile on Ubuntu 2.6.31 but I get the following error when I run make: Making all in src make[2]: Entering directory `/home/stuart/openbsc/openbsc/src' CCLD bsc_hack libmsc.a(gsm_04_08.o): In function `mm_rx_id_resp': /home/stuart/openbsc/openbsc/src/gsm_04_08.c:259: undefined reference to `gsm48_mi_to_string' libmsc.a(gsm_04_08.o): In function `mm_rx_loc_upd_req': /home/stuart/openbsc/openbsc/src/gsm_04_08.c:345: undefined reference to `gsm48_mi_to_string' libmsc.a(gsm_04_08.o): In function `gsm48_rx_mm_imsi_detach_ind': /home/stuart/openbsc/openbsc/src/gsm_04_08.c:685: undefined reference to `gsm48_mi_to_string' libmsc.a(gsm_04_08.o): In function `gsm48_rx_mm_serv_req': /home/stuart/openbsc/openbsc/src/gsm_04_08.c:642: undefined reference to `gsm48_mi_to_string' libbsc.a(gsm_04_08_utils.o): In function `gsm48_paging_extract_mi': /home/stuart/openbsc/openbsc/src/gsm_04_08_utils.c:262: undefined reference to `gsm48_mi_to_string' collect2: ld returned 1 exit status make[2]: *** [bsc_hack] Error 1 make[2]: Leaving directory `/home/stuart/openbsc/openbsc/src' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/home/stuart/openbsc/openbsc' make: *** [all] Error 2 Any ideas?

openbsc with softBTS

by Fadil Berisha

I am doing some experimenting with openbsc with software emulation of ipaccess. At this early stage, I am communicating with openbsc with hard coded messages. Here is what getting as response from openbsc: ./bsc_hack --debug=DNM:DRSL DB: Database initialized. DB: Database prepared. <0005> bsc_init.c:626 bootstrapping OML for BTS 0 <0005> abis_nm.c:583 OC=BASEBAND TRANSCEIVER(04) INST=(00,ff,ff) SW Activate Request: ACKing and Activating <0005> abis_nm.c:934 Found SW config: 42 12 00 05 01 02 03 04 05 13 00 05 05 04 03 02 01 <0005> abis_nm.c:1482 state 4, NM MT 0x0e <0005> abis_nm.c:1581 Activate Software DONE! <0005> abis_nm.c:583 OC=BASEBAND TRANSCEIVER(04) INST=(00,ff,ff) Software Activated Report <0005> abis_nm.c:583 OC=BTS(01) INST=(00,ff,ff) IPACCESS(0xe1): RSL CONNECT ACK PORT=3003 Openbsc responding properly on PING from softBTS in both links for OML and RSL. Looks like OML and RSL connection are established, but, here is problem. To get RSL CONNECT ACK PORT=3003, I send OML message NM_MT_IPACC_RSL_CONNECT_ACK before recieving request NM_MT_IPACC_RSL_CONNECT from openbsc. My question is, how to get in stage when openbsc is ready to send NM_MT_IPACC_RSL_CONNECT. What expecting openbsc to get from ipaccess before sending NM_MT_IPACC_RSL_CONNECT? Thank you Fadil Berisha

AW: openbsc with softBTS

by Andreas.Eversberg

> I'll try to port my OpenBTS Abis/IP code against current OpenBTS and > release it soon. hi harald, i hope i undertood it right. does that mean that OpenBTS will be able to connect to a BSC like OpenBSC? that would be extreemly interesting when using USRP as BTS with other than GSM-P (900) and DCS 1800/1900 band. andreas

Can't start nanoBTS properly.

I downloaded and built the latest version of openbsc/libosmocore (that's today's version), but when running, it hangs on this part: <0005> abis_nm.c:519 OC=BASEBAND TRANSCEIVER(04) INST=(00,00,ff) IPACCESS(0xe1): RSL CONNECT ACK IP=10.100.1.22 PORT=3003 STREAM=0x00 <0005> abis_nm.c:519 OC=CHANNEL(03) INST=(00,00,00) CHANGE ADMINISTRATIVE STATE NACK CAUSE=Message cannot be performed <0005> abis_nm.c:519 OC=CHANNEL(03) INST=(00,00,01) CHANGE ADMINISTRATIVE STATE NACK CAUSE=Message cannot be performed <0005> abis_nm.c:519 OC=CHANNEL(03) INST=(00,00,02) CHANGE ADMINISTRATIVE STATE NACK CAUSE=Message cannot be performed <0005> abis_nm.c:519 OC=CHANNEL(03) INST=(00,00,03) CHANGE ADMINISTRATIVE STATE NACK CAUSE=Message cannot be performed <0005> abis_nm.c:519 OC=CHANNEL(03) INST=(00,00,04) CHANGE ADMINISTRATIVE STATE NACK CAUSE=Message cannot be performed <0005> abis_nm.c:519 OC=CHANNEL(03) INST=(00,00,05) CHANGE ADMINISTRATIVE STATE NACK CAUSE=Message cannot be performed <0005> abis_nm.c:519 OC=CHANNEL(03) INST=(00,00,06) CHANGE ADMINISTRATIVE STATE NACK CAUSE=Message cannot be performed <0005> abis_nm.c:519 OC=CHANNEL(03) INST=(00,00,07) CHANGE ADMINISTRATIVE STATE NACK CAUSE=Message cannot be performed <0005> abis_nm.c:519 OC=RADIO CARRIER(02) INST=(00,00,ff) STATE CHG: OP_STATE=Disabled AVAIL=Off line(03) <0005> abis_nm.c:519 OC=RADIO CARRIER(02) INST=(00,00,ff) Software Activated Report <0005> abis_nm.c:1770 Set TRX Attr (bts=0,trx=0) <0005> abis_nm.c:519 OC=RADIO CARRIER(02) INST=(00,00,ff) Sending OPSTART <0005> abis_nm.c:519 OC=RADIO CARRIER(02) INST=(00,00,ff) STATE CHG: OP_STATE=Disabled AVAIL=OK(ff) ADM=Unlocked <0005> abis_nm.c:519 OC=RADIO CARRIER(02) INST=(00,00,ff) Sending OPSTART It stops there and nanoBTS keeps blinking green light. When running an older version (without libosmocore), it works well. Is this a familiar behaviour, any idea? Thnx.

Thank you Holger. Info was there, proper SW Activate Report message solved problem.

building a connection (and communication) between two different nanoBTS GSM Cells

by Fabrice Ismael Poundeu Tchouatieu

Hallo guys, just a question. Did some of you can tell me the best way to connect two different GSM cells (two nanoBTS) and build the communication between the two of them over my IP network? Which components(Astersik, LCR, mISDN ....)are requested for that? is it possible at all? Thanks!! -- Fabrice Ismael Poundeu Tchouatieu ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

OpenBSC GPRS status update

by Harald Welte

Hi all! As some of you may have noticed, there are some references to GPRS in the openbsc 'master' branch now. The code in there is sufficient to configure a nanoBTS via OML and RSL (SI13) to establish contact with an existing NS-over-IP capable SGSN. All that needs to be done is to set a couple of parameters at the BTS level in openbsc.cfg. I've documented them briefly in the wiki (VTY reference page). Also, at least one of your timeslots have to be of PDCH pchan type. We don't implement dynamic TCH/PDCH switching yet. As the changes required to get this initialization/configuration done are non-invasive, I decided to include them in the master branch right away. If you set 'gprs enabled 0' in your openbsc.cfg, all GPRS functionality should be disabled. This is of course only the first step. The much bigger work will be in the grps-sgsn branch, where work will continue on completing the BSSGP and LLC protocol implementations and the actual SGSN + GGSN functionality. The goal is of course to eliminate the need for an external SGSN/GGSN completely.
