Re: MS cannot connect; Location Update Request not received by BTS

by Hossein Amini

I installed master branch now(4/feb/2017 at 18:30) and retry, but I can not release channel and receive error in nitb. I do not access to a external timing source like octoClock, do you use external timing source? do you have a easy solution to check that? My NITB log is like your log by 20170203014240662 and repeat. I retried connecting about 10 min but nothing happened. NITB log that repeat is: 20170204071216381 DRLL <0000> chan_alloc.c:352 (bts=0,trx=0,ts=0,pchan=CCCH+SDCCH4) Allocating lchan=0 as SDCCH 20170204071216381 DRSL <0004> abis_rsl.c:1819 (bts=0,trx=0,ts=0,ss=0) Activating ARFCN(0) SS(0) lctype SDCCH r=LOCATION_UPDATE ra=0x06 ta=0 20170204071216381 DRSL <0004> abis_rsl.c:580 (bts=0,trx=0,ts=0,pchan=CCCH+SDCCH4) Tx RSL Channel Activate with act_type=INITIAL 20170204071216381 DRSL <0004> abis_rsl.c:1189 (bts=0,trx=0,ts=0,ss=0) state NONE -> ACTIVATION REQUESTED 20170204071216381 DRSL <0004> abis_rsl.c:1546 (bts=0,trx=0,ts=0,ss=0) CHANNEL ACTIVATE ACK 20170204071216381 DRSL <0004> abis_rsl.c:1189 (bts=0,trx=0,ts=0,ss=0) state ACTIVATION REQUESTED -> ACTIVE 20170204071226381 DRSL <0004> abis_rsl.c:852 (bts=0,trx=0,ts=0,ss=0) RF Channel Release due to error: 1 20170204071226381 DRSL <0004> abis_rsl.c:762 (bts=0,trx=0,ts=0,ss=0) DEACTivate SACCH CMD 20170204071226381 DRSL <0004> abis_rsl.c:1189 (bts=0,trx=0,ts=0,ss=0) state ACTIVE -> RELEASE DUE ERROR 20170204071226382 DRSL <0004> abis_rsl.c:925 (bts=0,trx=0,ts=0,ss=0) RF CHANNEL RELEASE ACK 20170204071228382 DRSL <0004> abis_rsl.c:811 (bts=0,trx=0,ts=0,ss=0) is back in operation. 20170204071228382 DRSL <0004> abis_rsl.c:1189 (bts=0,trx=0,ts=0,ss=0) state RELEASE DUE ERROR -> NONE On Fri, Feb 3, 2017 at 2:28 AM, Neels Hofmeyr <neels(a)hofmeyr.de> wrote: > Dear Hossein, > > the mailing list is indeed the proper place to ask.

Downtime due FreeBSD upgrade.

by Holger Freyther

Hi, the machine hosting most of *.osmocom.org is running FreeBSD9.3 which EOLed end of december and I would like to upgrade to FreeBSD10.3. I do not expect many problems but I also don't want to interfere with other peoples work. Even if it is short notice, any objections for Saturday->Sunday night of a European timezone? Otherwise I would pick next Friday->Saturday. regards holger
