Working GSM1800 config for latest OpenBSC

by Stephen Mortimer

I have a ip.access nanoBTS (version 165AU9012)v(37) and have been using it with a very early version of OpenBSC (OpenBSC 0.01) and am now trying to upgrade to the latest version downloaded from GIT (OpenBSC version 0.9.0.565-993d). When I use the configuration that works on the old version, with this latest version, I get the following error: user@ubuntu:~/openbsc/src$ ./bsc_hack <0005> bsc_init.c:1024 WARNING: You are running an 'accept-all' network on a BTS that is not barred. This configuration is likely to interfere with production GSM networks and should only be used in a RF shielded environment such as a faraday cage! <0005> bsc_init.c:1024 WARNING: You are running an 'accept-all' network on a BTS that is not barred.

ipaccess-config now able to set static IP address / mask / gateway

by Harald Welte

Hi! I've committed some changes to enable ipaccess-config to set static IP address, netmask and gateway. A full command looks like this: ./ipaccess/ipaccess-config -U dhcp-enabled -S static-ip -S static-gw -i 192.168.100.222/255.255.255.0 -g 192.168.100.1 -r 192.168.100.120 This will * unset DHCP client functionality * set static IP address nvram flag * set static gateway nvram flag * set the BTS IP to 192.168.100.222 netmask 255.255.255.0 * set the default gateway to 192.168.100.1 * restart the BTS Regards, Harald -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."

Arfcn calculation tool

by dexter

Hi Folks. I always found it annoying to calculate the correspondending frequency of an arfcn by hand or with the webbased arfcn calculator. So i wrote a little program to do the work for me: http://www.root.runningserver.com/web/runningserver/software/arfcncalc.tar Maybe the one or other here on the list will find it useful. regards.

BSC API updates

by Holger Freyther

Hi all, I just pushed zecke/remove-use-count with two commits to almost complete the split. This code allocates the "struct gsm_subscriber_connection" dynamically and the follow on commit is removing the use_count and releases a channel as soon as it is unused (no operation/transaction is left on it). I would like to land this code now and continue with: -) Land some channel release changes from the On-Waves branch -) Update the channel release documentation... -) Start recreating the osmo-bsc... -) Implement the assignment command and use it from gsm_04_08.c and suddenly we can easily switch from very early to early assignment...

Segmentation fault while sending sms via bsc_hack_VTY

by Richard M. Zahoransky

Hello, We have a working OpenBSC-LCR-Asterisk setup by now. Sending SMS from one cell phone to another works perfectly after typing "sms send pending" in the vty-console. Is it always needed to trigger the sms-sending manually or is there a fixed intervall in which sms will be transfered? Still a problem exists. If we try to send a sms directly from the bsc_hack_vty with "subscriber extension xxx sms send "TEXT"", the bsc_hack crashes: <0008> paging.c:225 Start paging of subscriber 36 on bts 0. <0008> paging.c:225 Start paging of subscriber 36 on bts 1. <0008> paging.c:87 Going to send paging commands: imsi: '262012840035907' tmsi: '0x79d38c8e' <0008> paging.c:87 Going to send paging commands: imsi: '262012840035907' tmsi: '0x79d38c8e' <0008> paging.c:87 Going to send paging commands: imsi: '262012840035907' tmsi: '0x79d38c8e' <0008> paging.c:87 Going to send paging commands: imsi: '262012840035907' tmsi: '0x79d38c8e' <0004> abis_rsl.c:1165 (bts=0,trx=0,ts=0,ss=0) Activating ARFCN(871) SS(0) lctype SDCCH r=LOCATION_UPDATE ra=0x15 <0004> abis_rsl.c:969 (bts=0,trx=0,ts=0,ss=0) CHANNEL ACTIVATE ACK <0009> abis_rsl.c:831 MEASUREMENT RESULT NR=0 RXL-FULL-ul=-108dBm RXL-SUB-ul=-108dBm RXQ-FULL-ul=6 RXQ-SUB-ul=6 BS_POWER=0 NOT VALID NUM_NEIGH=0 <0005> abis_nm.c:519 OC=BASEBAND TRANSCEIVER(04) INST=(00,00,ff) Failure Event Report Type=processing failure Severity=warning level failure <0000> abis_rsl.c:1276 (bts=0,trx=0,ts=0,ss=0) SAPI=0 ESTABLISH INDICATION <0003> gsm_04_08.c:799 PAGING RESPONSE: mi_type=0x04 MI(2043907214) <0003> gsm_04_08.c:817 <- Channel was requested by 262012840035907 <0008> paging.c:289 Stop paging on bts 0, calling cbfn. <0007> gsm_04_11.c:1151 paging_cb_send_sms(hooknum=1, event=0, msg=(nil),lchan=0x85365d8, sms=0x859cd58) <0008> paging.c:293 Stop paging on bts 1 silently. <0009> abis_rsl.c:831 MEASUREMENT RESULT NR=1 RXL-FULL-ul=-47dBm RXL-SUB-ul=-47dBm RXQ-FULL-ul=6 RXQ-SUB-ul=6 BS_POWER=0 L1_MS_PWR= 2dBm L1_FPC=0 L1_TA=0 NOT VALID NUM_NEIGH=0 <0000> abis_rsl.c:1276 (bts=0,trx=0,ts=0,ss=0) SAPI=0 DATA INDICATION <0003> gsm_04_08.c:835 CLASSMARK CHANGE CM2(len=3) CM3(len=2) <0009> abis_rsl.c:831 MEASUREMENT RESULT NR=2 RXL-FULL-ul=-47dBm RXL-SUB-ul=-47dBm RXQ-FULL-ul=0 RXQ-SUB-ul=0 BS_POWER=0 L1_MS_PWR= 2dBm L1_FPC=0 L1_TA=0 RXL-FULL-dl=-47dBm RXL-SUB-dl=-47dBm RXQ-FULL-dl=7 RXQ-SUB-dl=3 NUM_NEIGH=1 <0009> abis_rsl.c:863 IDX=0 ARFCN=877 BSIC=63 => -56 dBm <0000> abis_rsl.c:1276 (bts=0,trx=0,ts=0,ss=0) SAPI=3 ESTABLISH CONFIRM <0007> gsm_04_11.c:1125 rll_ind_cb(lchan=0x85365d8, link_id=3, sms=0x859cd58, type=0 <0007> gsm_04_11.c:1057 send_sms_lchan() <0001> transaction.c:69 subscr=0x859cb98, subscr->net=0x8533960 Program received signal SIGSEGV, Segmentation fault. 0x003a4785 in ??

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, List! I found a bug in OpenBSC.

It only does that when in an active dedicated channel (either a call or a sms or some other transaction). If you enable the debug for the DMEAS (either in the console or with the -d option), you should see those reports. Also, it sends reports only for neighbor cell of your network (as specified in the BCCH SI messages). Cheers, Sylvain

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, List! As I promise, here my patch, to solve the problem I explained on 18.06.2010.

Measuring signal

by Luca Bertoncello

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, again! I have another question, and this is: how can I measure the distance of a mobile from a BTS? I'm reading the book "Die GSM-Dm-Kanäle im Dialog" by Joachim Göller, and I learned, that a mobile phone sends, about every second, a MEASUREMENT REPORT to the station, where it is logged. In this report the mobile sends the signal power of the cell, where it is logged, and of other neighborhood cells. With these signals, I can measure the distance of the mobile from my cell(s). But I don't understand how can I get this values using OpenBSC. Can someone explain me how can I do this? Thanks a lot! - -- _______________________________________________________________________ Luca Bertoncello Entwicklung Mail: bertoncello(a)netzing.de NETZING Solutions AG Tel.: 0351/41381 - 0 Kesselsdorfer Str. 216, 01169 Dresden Fax: 0351/41381 - 12 HRB 18926 / Ust.ID DE211326547 Mail: netzing.ag(a)netzing.de _______________________________________________________________________ -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) iD8DBQFMIb5RAXzltVKV/2wRAv4zAKDpdHjed/uWweDtoknOaaHIOZlB1QCgtkhs 2jxsdaR/Y2ZmHdT1Nh/mVVY= =9tWf -----END PGP SIGNATURE-----
