To just "see" the network, the phone does not have to send anything and the BS-11 does not need to receive anything. This is necessary only when the phone registers to the network (Location Update). However the Abis link has to be up so that the cell information is sent, if the Abis link is down, the transmitter is most certainly still sending (I measured this here, but it was not yet confirmed by others so it might be wrong) but a phone won't see the network (probably no system information is sent in this case). > also i can create BBSIG1 and PA1, but it will not be used by bsc_hack. > what do i need to change in order to use the second transponder? maybe > this one works. I am not sure if OpenBSC already supports the second TRX. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

BS-11 runs, but no Network on my Mobile
by Andreas.Eversberg 01 Apr '09

hi, i finally completed the BS-11 setup: - original kernel 2.6.27.4 the mISDN-patch was for - bs11 with software load as described in the wiki - all BS-11 objects created as described - PA test passed - LMT shows no alarms (except cabinet-alarm) - after start of bsc_hack, all 8 channels on the first tansmitter are provisioned. - FM receiver clearly receives transmitter on channel 123, where no other base station is transmitting but i do not get any other network on my mobile. my mobile just finds: e-plus, t-mobile, o2, vodafone any ideas? thanx in advance andreas

The error message that LMT is not compatible to the firmware version should be no problem, it just complains about unknown attributes. Its strange, because you already know that the transmitter is working, so I wonder why you don't receive something on the phone. Have you tried a different phone, just to be sure ? Maybe also using a different ARFCN might help. Best regards, Dieter -- Dieter Spaar, Germany spaar(a)mirider.augusta.de

I most certainly cannot help this way, if bsc_hack sends the configuration and LMT shows no alerts than the BS-11 should actually work as configured by bsc_hack.

Have you already tried to restart OpenBSC ? I sometimes had the impression that the first configuration of the BS-11 after it has been turned on does not work.

the load is correct. i get an error pop-up while starting bsc_hack. this is because the LMT seems not to be 100% compatible with the load. with an older load i don't get this error pop-up, but it also doesn't work. also no alarms show on the LMT after syncing database. i will get the exact error message this weekend. -----Ursprüngliche Nachricht----- Von: Dieter Spaar [mailto:spaar@mirider.augusta.de] Gesendet: Mittwoch, 1.

i tried two different loads, many reboots. also i reconfigured the objects (delete / create). many restarts of the bsc_hack always gave the same results. transmitter is working fine, but no network indication on my mobile.

BS11 configuration problem
by Michael Gernoth 31 Mar '09

31 Mar '09

Hi, after receiving an E1 card, I tried (unsuccessfully) to get bsc_hack up and running: http://pbot.rmdir.de/19e2baa94ffedfdb814dce0a9346532e After that, no new network can be found with a mobile phone. bs11_config is reporting: PHASE: 3 Normal MBCCU0: Load MBCCU1: Load Abis-link: Up When bsc_hack is started, the following message appears a huge number of times in the kernel log: Mar 1 17:24:51 faui43g kernel: mISDN_send: error -12 and then sometimes messages like: Mar 1 17:24:52 faui43g kernel: ph_data_indication 0x0 0x3 0x0 The kernel version is 2.6.27.19 (patched), but I also tried the newest git tree from Linus with the same results. I think the configuration of my BS-11 is somehow broken, as both TRX seem to be enabled: BS11 Power Amplifier 0 ATTRIBUTES: TRX Power: 30mW (GSM) BS11 Power Amplifier 1 ATTRIBUTES: TRX Power: 30mW (GSM) But running bs11_config delete-trx1 (or create-trx1) just produces BS11 DELETE OBJECT NACK (respectively BS11 CREATE OBJECT NACK): http://pbot.rmdir.de/53344f67ed0cb86f24c4a79f0af4fe2e Trying to reset the standard configuration by deleting and recreating all objects in create_objects() doesn't work, too: http://pbot.rmdir.de/13e0b928689c0d527b13fa52698b9391 (Patch: http://pbot.rmdir.de/e549a8a52da6d389326e2e2891c2f289) It seems to me, that I have to reset the BS-11 to the factory defaults and recreate the configuration with bs11_config, but I don't know how to do that (and if I need the firmware files for that...). Did I miss something obvious, or is the configuration of my BS11 somehow broken?

RequestForHelp on mISDNUser
by Holger Freyther 31 Mar '09

31 Mar '09

Hey guys, some month ago I added basic support to dump the LAPD frame we send and receive. This code was disabled in Haralds restructuring of this layer in order to add support for the IP Access nanoBTS. The question is now should we repair or nuke this feature. Shortly after having finished my implementation prom pointed me to the mISDNuser tool[1]. It looks like this can write pcap files as well and that wireshark should be able to handle them. I would be happy if someone could try this tool and see what files are produced and if we should continue this way or restore the "-p file" functionality. thanks z. PS: Maybe we just need to move the pcap Linux-LAPD header over to this tool... [1] http://git.misdn.org/?p=mISDNuser.git;a=blob;f=debugtool/mISDNdebugtool.c;h…

SMS are now stored in SQL table
by Harald Welte 31 Mar '09

31 Mar '09

Hi all! Today I've just committed some code that stores incoming SMS in the SQL table as soon as they are received. There is also more error handling right now, i.e. if the SMS is sent to an unknown extension, it is rejected right away. What's still missing is the code to actually deliver the SMS from the SQL table to the destination phone. For this, we need to * decouple paging from voice calls * correctly construct TPDU and RP/CP header from actual SMS payload * trigger SMS delivery of pending messages at LOCATION UPDATING / IMSI ATT * trigger SMS delivery once the MS tells us it has memory (SMMA) * regularly iterate over undelivered SMS and try to send them * decide how to handle SMS while a voice call is ongoing If anyone has a good idea what to do about UCS2 encoded messages, I'm more than happy to hear about it. My plan so far is to translate it to UTF-8 and store it as UTF-8 in the SQL database. This way we have something that most linux systems (and other tools) can deal with. Disadvantage is that we'd end up translating a message back and forth... Also, if somebody is more familiar with the 'regular' SMSC architecture in real GSM networks, it would probably be good to think of a way how we can integrate external SMS delivery both incoming and outgoing. SMS is much easier since it is basically data/signalling only and there's no need to actually route unstructured voice data like it is the case for regular phone calls. -- - Harald Welte <laforge(a)gnumonks.org> http://laforge.gnumonks.org/ ============================================================================ "Privacy in residential applications is a desirable marketing option."
