connecting two nanoBTS-GSM-Cells
by Fabrice Ismael Poundeu Tchouatieu 12 Apr '10

12 Apr '10

Hallo everyone, i'm trying to connect two nanoBTS-GSM-Cells together to simulate two different GSM Subscriber networks. I have tried to make it using lcr and asterisk but they were some difficulties using mISDNv2. Certainly some of you have made such a connection before. I just want to known if someone can tell me the best way to make such a connection and which components are necessary for that? -- Fabrice Ismael Poundeu Tchouatieu ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

Well, it is unlikely that it ignores the content. It is more likely that you are not using the database you think you are using. type bsc_hack and find the option to specify the path to the database, do a ls -la /proc/`pidof bsc_gack/fd to see which database was opened.

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 08 Apr '10

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

> 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
