[PATCH 1/2] gprs: Fix VTY NSVC initialisation bug by changing gprs_nsvc_create()
by Jacob Erlbeck 11 Nov '13

11 Nov '13

Currently the field nsvci_is_valid is set to 0 in the NSVC object returned by gprs_nsvc_create(). This was a semantic change probably introduced by commit 5e6d679d. As a result, NSVC created via the VTY have this flag set to 0 causing RESET_ACK messages to be rejected. This patch changes the default behaviour of gprs_nsvc_create() to always set this flag. So it must be set to 0 explicitely if needed which is more intuitive and thus less error prone. It fixes breaking connections from the Gbproxy to the SGSN.

OPENBSC/LCR/Asterisk
by Leonardo Nve 11 Nov '13

11 Nov '13

Hi, I have installed an infrastructure IPACCESS - OpenBSC - LCR (without misdn) - Asterisk LCR si connected via SIP to Asterisk. The problem is that i can call MT <-> softphone, soft and MT <-> MT BUT i don't hear anything in any side ( softphone <-> softphone works well). I think is a codec problem: Configured TCH/F FR for MT and we tried different codecs (alaw,gsm,ulaw, etc etc). Also I tried bridging GSM and SIP interfaces on LCR config and putting rtp-bridge. On LCR debug I see this error: 000000 DEBUG (in port.cpp/new_state() line 267): PORT(SIP-0-out) new state PORT_STATE_OUT_ALERTING --> PORT_STATE_CONNECT nua: nua_application_event: entering 000000 DEBUG (in sip.cpp/sip_callback() line 1775): Event 7 from stack received (handle=0x94906d8) 000000 DEBUG (in sip.cpp/sip_callback() line 1825): state change received nua: nua_application_event: entering 000000 DEBUG (in sip.cpp/sip_callback() line 1775): Event 7 from stack received (handle=0x94906d8) 000000 DEBUG (in sip.cpp/sip_callback() line 1825): state change received nua: nua_application_event: entering 000000 DEBUG (in sip.cpp/sip_callback() line 1775): Event 5 from stack received (handle=0x94906d8) 000000 DEBUG (in sip.cpp/sip_callback() line 1837): active received 000000 TRACE 06.11.13 20:10:06.434 EP(2): CONNECT from CH(2) connect id number= present='not available' 000000 TRACE 06.11.13 20:10:06.435 EP(1): CONNECT to CH(1) connect id number= present='not available' 000000 TRACE 06.11.13 20:10:06.435 EP(1): TONE to CH(1) off 000000 TRACE 06.11.13 20:10:06.436 CH(1): MNCC_SETUP_RSP LCR<->BSC connected type=0 plan=1 present=0 screen=3 number= 000000 DEBUG (in port.cpp/new_state() line 267): PORT(GSM-0-in) new state PORT_STATE_IN_ALERTING --> PORT_STATE_CONNECT_WAITING 000000 DEBUG (in port.cpp/message_epoint() line 617): PORT(GSM-0-in) setting tone '' dir '' 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 TRACE 06.11.13 20:10:06.563 CH(1): MNCC_SETUP_COMPL_IND LCR<->BSC 000000 DEBUG (in port.cpp/new_state() line 267): PORT(GSM-0-in) new state PORT_STATE_CONNECT_WAITING --> PORT_STATE_CONNECT 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. 000000 DEBUG (in gsm.cpp/audio_send() line 487): no valid CMR yet. <--...--> <-- THIS ERROR REPEATED CONTINUOUSLY DURING THE CALL --> <--...--> Configurations: OpenBSC trx 0 config: trx 0 rf_locked 0 arfcn 636 nominal power 23 max_power_red 0 rsl e1 tei 0 timeslot 0 phys_chan_config CCCH+SDCCH4 hopping enabled 0 timeslot 1 phys_chan_config SDCCH8 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 mncc-int default-codec tch-f fr LCR config: interfaces.conf [GSM] gsm-bs tones yes earlyb no [SIP] extern sip localhost:5059 localhost:5060 tones yes earlyb yes Asterisk User conf: user.conf (one user) [6001] fullname = SIPPhone2 registersip = no host = dynamic callgroup = 1 mailbox = 6001 call-limit = 100 type = peer username = 6001 secret = nomypasshere transfer = yes nat = yes context = openBSC_Integration dtmfmode = rfc2833 cid_number = 6001 disallow = all allow = alaw,gsm ; I Tried different codecs callcounter = no hasvoicemail = no vmsecret = email = threewaycalling = no hasdirectory = no callwaiting = no hasmanager = no hasagent = no hassip = yes hasiax = no canreinvite = no insecure = no pickupgroup = 1 autoprov = yes label = 6001 linenumber = 1 LINEKEYS = 1 Other configs seem irrelevant... -- -- Leonardo Nve <lnve(a)s21sec.com> Project Manager ACSS Grupo S21sec Gestión, S.A.

Openbsc support for new BTS
by Jason DSouza 08 Nov '13

08 Nov '13

Hello Harald and everyone out there! I have been going through your Osmocom projects especially Openbsc (osmo-nitb) and Osmobts projects and I must say it's a real great work! I'm a lead engineer at Octasic and after looking at your work on OpenBSC and OsmoBTS, we decided to use your OpenBSC stack for internal testing of our Octasic PHY. I know currently openbsc supports few BTS models like ip.access, sysmocom etc. I have gone through the wiki and some of the openbsc archives. I could find an archive regarding Octasic SDR, but I guess it has not gone any further. http://lists.osmocom.org/pipermail/openbsc/2010-November/002196.html I will be interested in osmo-nitb which I can use for network part of GSM and use osmo-bts for BTS L2/L3 stuff, which already has abis-over-ip interface to openBSC(osmo-nitb). I have Octasic SDR hardware that has the layer1 (DSP image), so all I need to implement is the interfaces between Octasic Layer1 and osmobts L2/L3 to communicate between them, which I'm working on. I have already installed openbsc (osmo-nitb) and also osmobts on my Debian 7.1.0. I'm currently in a process of writing interfaces between Octasic L1 and osmobts. I'm using the default config file openbsc.cfg for osmo-nitb & using ip.access config file for osmobts (with changes in the OML ip & band GSM900) At present I'm trying to get TRX config request from osmo-nitb. However though I'm receiving few OML messages like NM_MT_SET_BTS_ATTR (pcap attached), I guess they are specific to ip.access BTS, I'm not able to see any TRX config request coming from osmo-nitb (Or by any chance is that what I'm receiving is the TRX config one?) I'm simply sending ack for those OML messages and eventually expecting a TRX config request from osmo-nitb. I'm not sure if osmo-nitb expects something to se sent from BTS side, looks like it is simply waiting for something(see below). I have tried to run osmo-nitb program and it look like: ./osmo-nitb -c openbsc.cfg <0019> input/ipaccess.c:934 enabling ipaccess BSC mode DB: Database initialized.

At present, I have just created socket interface from osmo-bts to octasic L1 and I'm in the process of writing interfaces for the messages. I'm expecting 1st message, TRX config request from osmo-nitb and do not see it. I was thinking, once the abis interface is up (OML link), osmo-nitb will trigger TRX configuration and then based on the response from BTS, other configurations. Does osmo-nitb require some kind of handshake from the BTS side to send the TRX configuration? I shall be really grateful to hear advices from the experts out there. I can give you more information if required. Thanks, Jason D'Souza

New handover algorithm with Nokia BTS
by Sipos Csaba 06 Nov '13

06 Nov '13

I just wanted to ask before I spend a lot of time with it. Does the new HO algorithm also works with non-IP based BTSes like Nokia metro or insite? Or at least in theory it should work? Because the handover is not working with the current algo for Nokia, I want to give the new one a try. Csaba

[PATCH 1/2] sysmobts: Only set RC state to LOCK if all channels are muted
by Jacob Erlbeck 06 Nov '13

06 Nov '13

Currently only mute_state[0] (refers to ts[0]) is inspected to determine, whether the Radio Carrier's state is set to LOCK. This patch changes this by looking at all channels and using LOCK if (and only if) all channels have been muted successfully.

OpenBSC + LCR + Asterisk = half sided calls in one direction
by Sipos Csaba 05 Nov '13

05 Nov '13

Hi, I am setting up openbsc with LCR and Asterisk to provide external connectivity for the GSM clients, and I encountered and interesting problem. If the GSM phone initiates a voice call towards a SIP phone it works perfectly, the voice goes both ways, the quality is OK, everything is fine. But when the SIP phones initiates a voice call towards the GSM phone, only the SIP phone can hear the voice of the GSM phone, and not the other way around (half sided call). The connection setup works both ways just fine. The GSM and the SIP phone can also call the asterisk test numbers, and even can do echo test just fine. The two GSM phones can call each other too without any problem. Does somebody has any idea what could go wrong? Config: E1 based Nokia BTS with DAHDI card and TCH/F FR codec. The SIP phone uses Alaw, LCR also set to use Alaw. The LCR is bridged to Asterisk, interface.conf: [GSM] gsm-bs tones yes earlyb no bridge ast [ast] remote asterisk context from-lcr earlyb no tones yes bridge GSM routing.conf is completely empty.

[PATCH] sysmobts: Use status flags instead of direct LED access
by Jacob Erlbeck 05 Nov '13

05 Nov '13

Currently the LEDs are being accessed directly from within the l1_if.c file. So the handling of rf mute and activate/deactivate both access LED_RF_ACTIVE directly. This may lead to an inconsistent LED status. This patch replaces these calls to sysmobts_led_set() by an abstract equivalent bts_update_status(), that uses a set of independant status ids. The associated values can than be combined into a visible LED status. Currently LED_RF_ACTIVE is on iff BTS_STATUS_RF_ACTIVE is set and BTS_STATUS_RF_MUTE is not set.

[PATCH 1/4] femto: Add L1P_T_INVALID to l1prim_type
by Jacob Erlbeck 05 Nov '13

05 Nov '13

Currently uninitialized elements of the femtobts_sysprim_type array are mistaken as L1P_T_REQ (which is accidently the first element and thus 0). This patch adds a new element to the enum that has the value 0 to detect uninitialized elements of the femtobts_sysprim_type array. Those will then show up in the log as 'SYS Prim XXX is not a Request!'. This patch also adds missing definitions of the CalibTbl messages in the femtobts_sysprim_type mapping so that the requests can still be identified as such.

[PATCH] bsc/ussd: Send faked CM Service Accept before sending USSD
by Jacob Erlbeck 01 Nov '13

01 Nov '13

The MS do not show the USSD messages yet. This patch modifies the implementation to insert a CM Service Accept before the ussdNotify to finish the establishment of the MM connection according to 3GPP TS 04.10/3.2.1. This fix has been tested with a Blackberry phone that has shown an ussd_grace_txt after rf_locked has been set to '1'. Without this patch, that message wasn't shown. The phone has sent a CC Setup and other messages before processing the channel release message sent by the BSC, but these messages have not been forwarded to the MSC (as expected).
