Hello everyone! Right now I am moving some code from OsmoBTS to libosmocore, exactly OsmoBTS/src/osmo-bts-trx/gsm0503*. And there is a licensing conflict, because this code licensed under AGPLv3+, but libosmocore code is GPLv2+. So, this is why I am contacting all authors/copyright holders. The question is: does everyone agree to re-license the code under GPLv2-or-later and move it code to libosmocore? Thanks in advance! With best regards, Vadim Yanitskiy.

MS Initial Registration failure observed in osmo-trx setup

by Mrinal Mishra

Hello All, We are trying to bring up osmo-trx setup in Ettus USRP B200 Board for Testing CS and PS call . When we tried to do the initial Registration for UE it is failing. Could you please help to point out what could be the issue and how to resolve this. Please find below the observation and log snippet for reference: After MS power Up Network is getting detected on the MS , Rach is received at BTS , Channel Activation is successful at A-bis interface and later Immediate Assignment is seen in the log. After Immediate assignment no further message is observed in Uplink/Downlink and later BSC is releasing the SDCCH/SACCH channel as observed from the log.

It is a patch from the Quickstart Guide for the new litecell15 board. Well, since it's already merged, I guess we won't mark it as a revert then, sorry about that.

Help Interpreting Classmark and sqlite BLOB storage

by Keith Whyte

Hi All, 2 (related) questions in 1 thread here: I'm looking at Chapter 10.5.1.7 of GSM 04.08, also Figure 10.5.7 there, but I am not quite getting how to interpret it in relation to either openBSC log output such as: <000d> db.c:1130 Sync Equipment IMEI=357371048322730, classmark1=33, classmark2=33 18 82 , classmark3=00 08 00 52 20 00 00 4b or equally: root@bsc:~# echo "SELECT classmark1 FROM Equipment where id='505';" | sqlite3 /var/lib/osmocom/hlr.sqlite3 | xxd 0000000: 3531 0a 51. root@bsc:~# echo "SELECT classmark2 FROM Equipment where id='505';" | sqlite3 /var/lib/osmocom/hlr.sqlite3 | xxd 0000000: 0132 1781 0a .2... root@bsc:~# echo "SELECT classmark3 FROM Equipment where id='505';" | sqlite3 /var/lib/osmocom/hlr.sqlite3 | xxd 0000000: 01ff 07ff 511f ffff 4a0a ....Q...J. Specifically, in this case, not having the mathematical theory, I don't understand how to map 01ff 07ff 511f ffff 4a0a to 00 08 00 52 20 00 00 4b It doesn't /quite/ match, but more importantly mapping to Classmark 3 Value Part Could you help me understand how to map 01ff 07ff 511f ffff 4a0a to Figure 10.5.7 BTW, I get that the BLOBs in sqlite are somehow encoded, (if that is not completely the wrong term to use) as hex_value-1, I've also noted this in the SMS table when trying to identify an sms in the sms_queue. So question part 2: what is that about? Is there an easy way I could "decode" on the command line, as in: echo "SELECT user_data FROM sms limit 1;" | sqlite3 /var/lib/osmocom/hlr.sqlite3 | some magic to display readable SMS content Any tips? Thanks!

tcp port 4252 used twice

by Neels Hofmeyr

When updating https://osmocom.org/projects/cellular-infrastructure/wiki/PortNumbers I noticed that 4252 is used both for OpenGGSN Ctrl as well as sysmobts-mgr VTY. Should we do something about that? Technically, we have VTY commands available to redirect the vty bind port, but sysmobts-mgr does not heed that VTY command yet.

PRACH fails

by Sipos Csaba

Dear Tom and List, I am in the process of updating the wiki for USRP radios, therefor I am recompiling everything Osmocom related with the latest master branches. I managed to setup the system, the CS services are working just fine (only fullrate and SMS is tested yet), but the GPRS service seems to be not working. I am using my well tested setup on 1800MHz (ARFCN 885), with duplex filters. On the Osmo-BTS end I get this message: <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access <0007> l1sap.c:957 RACH for packet access Osmo-PCU in the same time shows the following (repeatedly): Thu Sep 8 12:48:30 2016 DRLCMAC <0002> tbf.cpp:819 TBF(TFI=0 TLLI=0x00000000 DIR=UL STATE=WAIT ASSIGN) timer 3169 expired.

octasic build failure / header versions

by Neels Hofmeyr

Yesterday we had problems building the current osmo-bts-octphy with the current octphy-2g-headers. To resolve, we've reverted two commits and added a change in osmo-bts. (1) osmo-bts included a struct member not present anywhere in octphy-2g-headers. https://gerrit.osmocom.org/820 https://gerrit.osmocom.org/821 On our test setup at sysmocom, I found a version of the headers called OCTSDR-2G-02.05.00-B780-DEBUG that includes this struct member, but those headers have proprietary licensing. Also, the current version apparently is 2.07, while the one with the unknown struct header seems to be older: 2.05. So it looks like the usCentreArfcn item has been removed in a newer version, even though it looks really useful to me. It would be good to resolve this confusion, probably as soon as Max is back from vacation (Max is the author of the reverted commits). (2) In the most recent version, a #define naming has changed. In https://gerrit.osmocom.org/822 Holger asks: > Do we have any precedence of using #if for version checks? You can > use #ifdef for both of them to support old and new headers? We could use a check like #if cOCTVC1_HW_VERSION_MAJOR <=2 && cOCTVC1_HW_VERSION_MINOR < 7 [...]_IDLE[...] #else [...]_UNUSED[...] #endif but I doubt that we will want to go back to old headers. If I'm the only one in doubt, we'd have a check like above in three places in osmo-bts.

chan_alloc.c help

by Abdulghafar Shabaneh

Hi Neels and everyone in the list, Thanks for your help in installing OpenBSc on my Raspberry Pi :) It was as you said that I should delete it and build from scratch. The prefix command fixed the issue as well ./configure --prefix=/usr .. I was unable to install lcr due to an error: Makefile:1306: recipe for target 'chan_lcr.po' failed I don't know if that will fix the problem, though, its optional, and osmo-nitb should do the job by it self. Now I ran the osmo-nitb, osmo-bts-trx and osmo-trx all together with the USRP2 with FLEX900 daughter board GSM900 band, it all works well except the mobile is not able to register on the network. osmo-nitb shows this error: (towards the end) my file >trybsc.cfg contains this: ! password foo ! line vty no login ! e1_input e1_line 0 driver ipa network network country code 416 mobile network code 77 short name GSMab long name GSMab auth policy accept-all location updating reject cause 13 encryption a5 0 neci 1 paging any use tch 0 rrlp mode none mm info 1 handover 0 handover window rxlev averaging 10 handover window rxqual averaging 1 handover window rxlev neighbor averaging 10 handover power budget interval 6 handover power budget hysteresis 3 handover maximum distance 9999 timer t3101 10 timer t3103 0 timer t3105 0 timer t3107 0 timer t3109 0 timer t3111 0 timer t3113 60 timer t3115 0 timer t3117 0 timer t3119 0 timer t3122 10 timer t3141 0 dtx-used 0 subscriber-keep-in-ram 0 bts 0 type sysmobts band GSM900 cell_identity 0 location_area_code 1 training_sequence_code 7 base_station_id_code 63 ms max power 0 cell reselection hysteresis 4 rxlev access min 0 periodic location update 30 channel allocator descending rach tx integer 9 rach max transmission 7 ! channel-descrption attach 1 ! channel-descrption bs-pa-mfrms 5 ! channel-descrption bs-ag-blks-res 1 ip.access unit_id 1801 0 oml ip.access stream_id 255 line 0 neighbor-list mode automatic trx 0 rf_locked 0 arfcn 100 nominal power 0 max_power_red 0 rsl e1 tei 0 timeslot 0 phys_chan_config CCCH+SDCCH4 hopping enabled 0 timeslot 1 phys_chan_config TCH/F hopping enabled 0 timeslot 2 phys_chan_config TCH/F hopping enabled 0 timeslot 3 phys_chan_config TCH/F hopping enabled 0 timeslot 4 phys_chan_config TCH/F hopping enabled 0 timeslot 5 phys_chan_config TCH/F hopping enabled 0 timeslot 6 phys_chan_config TCH/F hopping enabled 0 timeslot 7 phys_chan_config TCH/F hopping enabled 0 pi@dwarfabd:~ $ sudo osmo-nitb -c ~/trybsc.cfg -l hlr.sqlite3 -P -C --debug=DRLL:DCC:DMM:DRR:DRSL:DNM <0005> bsc_init.c:498 VTY at 127.0.0.1 4242 <0005> bsc_init.c:427 WARNING: You are running an 'accept-all' network on a BTS that is not barred.

OsmoBTS -> libosmogsm code migration

by Vadim Yanitskiy

Dear all, We recently discussed with Harald, that there is a lot of code related to GSM L1 should be migrated from OsmoBTS to libosmogsm. The reason is that it would be better to have one shared implementation of the convolutional codes, mapping, interleaving, etc., because then in near future it can be used not only from OsmoBTS, but also from OsmocomBB and even from foreign projects, such as GR-GSM. I just started to work on this direction, and found that there is already some code, related to the conventional codes, in libosmogsm. But unlike OsmoBTS, where all the tables can be found within the single file named 'gsm0503_conv.c', these tables appears in separate files during building process. So, I have several questions: 1) Which approach is better to use? To store everything in a single file or to use auto generation (utils/conv_gen.py)? 2) What about the copyright? I have not seen any license/author info at the top pf these files. Who is the author? Also, there is the 'gsm0503_coding.c' file, which uses the following external dependences: * The DL1C logging category, which isn't defined in libosmocore; * The 'osmo-bts/gsm_data.h', which includes 'openbsc/gsm_data_shared.h' as well. So, there is regarding questions: 3) Which logging category it would be better to use after migration? 4) What to do with the 'osmo-bts/gsm_data.h'? 5) I don't think, that it's a good way to require something from the OpenBSC sources during OsmoBTS build... How can we change it? With best regards, Vadim Yanitskiy.

osmo-sip-connector codecs

by Anonim Stefan

Hi, Is there a way to make osmo-sip-connector advertise additional codecs (e.g.G711) besides GSM codec? Thanks, Stefan
