246tnt at gmail.com 246tnt at gmail.comWhen making a call from my test phone (a T610 here), I see the BSC assigning more than one channel ... For example, with a MO call : <0010> abis_rsl.c:1182 Activating ARFCN(514) TS(2) SS(0) lctype TCH/F chan_nr=0x0a r=OTHER ra=0xe7 <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=2) chan_nr=0x0a CHANNEL ACTIVATE ACK <0010> abis_rsl.c:1182 Activating ARFCN(514) TS(3) SS(0) lctype TCH/F chan_nr=0x0b r=OTHER ra=0xf8 <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=3) chan_nr=0x0b CHANNEL ACTIVATE ACK <0010> abis_rsl.c:1182 Activating ARFCN(514) TS(4) SS(0) lctype TCH/F chan_nr=0x0c r=OTHER ra=0xe3 <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=4) chan_nr=0x0c CHANNEL ACTIVATE ACK <0001> abis_rsl.c:1286 channel=(bts=0,trx=0,ts=4) chan_nr=0x0c sapi=0 ESTABLISH INDICATION <0004> gsm_04_08.c:1280 <- CM SERVICE REQUEST serv_type=0x01 mi_type=0x04 M(874908265) ... <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=4) chan_nr=0x0c CHANNEL MODE MODIFY ACK <0010> abis_rsl.c:1526 channel=(bts=0,trx=0,ts=4) chan_nr=0x0c IPAC_DISCONNECT_IND CAUSE=0x0f(Normal event, unspecified) <0001> abis_rsl.c:1286 channel=(bts=0,trx=0,ts=4) chan_nr=0x0c sapi=0 RELEASE INDICATION <0010> abis_rsl.c:721 RF Channel Release CMD channel=(bts=0,trx=0,ts=4) chan_nr=0x0c <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=4) chan_nr=0x0c RF CHANNEL RELEASE ACK <0002> gsm_subscriber_base.c:150 subscr 201 usage decreased usage to: 0 <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=2) chan_nr=0x0a CONNECTION FAIL: CAUSE=0x01(Radio Link Failure) RELEASING. <0010> abis_rsl.c:721 RF Channel Release CMD channel=(bts=0,trx=0,ts=2) chan_nr=0x0a <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=2) chan_nr=0x0a RF CHANNEL RELEASE ACK <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=3) chan_nr=0x0b CONNECTION FAIL: CAUSE=0x01(Radio Link Failure) RELEASING. <0010> abis_rsl.c:721 RF Channel Release CMD channel=(bts=0,trx=0,ts=3) chan_nr=0x0b <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=3) chan_nr=0x0b RF CHANNEL RELEASE ACK <0010> abis_rsl.c:721 RF Channel Release CMD channel=(bts=0,trx=0,ts=2) chan_nr=0x0a <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=2) chan_nr=0x0a RF CHANNEL RELEASE ACK <0010> abis_rsl.c:721 RF Channel Release CMD channel=(bts=0,trx=0,ts=3) chan_nr=0x0b <0010> abis_rsl.c:1001 channel=(bts=0,trx=0,ts=3) chan_nr=0x0b RF CHANNEL RELEASE ACK As you see, there was 3 TCH assigned ... (and of course two of those ultimately failed with Radio Link Failure ...). Is anyone else seeing this ? Sylvain -------------- next part -------------- An HTML attachment was scrubbed...
