Harald Welte 2c38aa8dcd * make sure we use the correct GSM48 encoding type 
* modify the RSL channel mode (BTS) side) after the 04.08 (MS side) has acked MODIFY
 2009-02-18 03:44:24 +00:00
Harald Welte 0b8348d397 fix the parsing of the 'normal' availability status 2009-02-18 03:43:01 +00:00
Harald Welte b110cee0a0 CONNECT TERRESTRIAL TRAFFIC needs to be in the CHANNEL object class in order to work 2009-02-18 03:42:35 +00:00
Harald Welte 7eb1f621e0 "the big fix", of the E1 subchannel [de]multiplexer. I don't even remember how 
many bugs I fixed during the last couple of hours.  It was never working at
any time before.

Harald Welte f9227c7562 write 160byte to one E1 TS at any given time, since that is one TRAU Frame (40 bytes) per sub-channel 2009-02-18 03:39:00 +00:00
Harald Welte 23887b607f use official TCH/F for initial channel modes rather than BS-11 specific 0x09 2009-02-18 03:37:20 +00:00
Harald Welte 41e166884e if TRAU frame decoding doesn't work, we don't need to even try to re-encode and just send an idle frame instead 2009-02-18 03:34:55 +00:00
Harald Welte da78376396 * ensure TCH/F are activated signalling-only 
* add function for RSL CHANNEL MODIFY REQUEST
* add missing channel activation function to header file
 2009-02-18 03:29:53 +00:00
Harald Welte 8e4ae95e0b #defines for GSM48 channel modes 2009-02-18 03:28:01 +00:00

Harald Welte 93d3f37f6c * disable TS3 TRAU frame handling for now 
* statically activate two sub-slots in TS2 (need to do this dynamic later)
 2009-02-18 03:27:14 +00:00
Harald Welte bb8c4061eb * use DEBUGP in TRAU frame code 
* make sure we actually set 'spare' bits to 1

Harald Welte 9e783318b0 strip mISDN hardware header before putting B-channel data into subchannel demuxer 2009-02-17 19:02:29 +00:00
Harald Welte 311d0cf245 don't reduce power quite as much to make sure we still get a singal (bs-11) and nanoBTS doesn't refuse the attribute at all 2009-02-17 17:45:59 +00:00
Harald Welte bfaf097905 in case pagign of the 'B-end' during call setup fails, transmit message to 
correct lchan rather than crashing
 2009-02-17 17:43:33 +00:00
Harald Welte 49dfa353e3 correctly print IPAC_CONNECT_ACK debug statement 2009-02-17 15:29:58 +00:00
Harald Welte 49f48b8b77 various CC updates:

* fix bug that prevented a CONNECt message to ever reach the 'B' side
 2009-02-17 15:29:33 +00:00

Harald Welte 677c21f4ab add parsing for ip.access vendor specific NM messages 2009-02-17 13:22:23 +00:00
Harald Welte 794d9b29f7 add bits and pieces of documentation 2009-02-17 02:02:14 +00:00
Harald Welte 7ccf77810b slightly more complete GSM 04.08 CC, we can now 
* initiate phone calls from one MS
* look-up the subscriber based on dialled extension
* page the called subscriber
* send the SETUP to the called subscriber, including CLIP/CLIR
* get ALERTING notification back to caller
* relay DISCONNECT from either side to the other
This is still far from being complete, but it at least works for the most common case
 2009-02-17 01:43:01 +00:00
Harald Welte 75a1fa834c switch paging code to use a timer again, since not all BTS send reliable CCCH load indications 2009-02-17 01:39:41 +00:00
Harald Welte 0932d1e2b4 forgot the header files in last commit. sigh. 2009-02-16 22:53:52 +00:00
Harald Welte 09e38afbcc * introduce a callback function when paging completes (I know this is somewhat of an overlap 
with the signals, but I think paging always has one reason and thus one caller wants to
  get notified about completion, including a caller-specific context, etc)
* introduce TLV parser definitions for GSM 04.08
* parse and generate BCD number IE's for 04.08 call control
 2009-02-16 22:52:23 +00:00

Harald Welte 595ad7b762 modify the signal handler/dispatch code (sorry zecke, no offense, I just had some different ideas) 
* introduce new notion of subsystem in addition to signal number
* no need for bitmasks of 'areas' (aka subsystems)
* pass subsystem/signal_nr/... per argument rather than by data structure
 2009-02-16 22:05:44 +00:00
Harald Welte 7509926614 * introduce TLV parser definitions for RSL IE's 
* introduce functions for ip.access specific RSL commands
 2009-02-16 21:12:08 +00:00

Harald Welte d4c9bf3c5a * add bs_power and ms_power attributes to each channel and use them in channel activation 2009-02-15 16:56:18 +00:00
Harald Welte cd99387bd2 * use more constants to name the various BTS/TRX/... attributes 
* set BS power reduction up to 30dB reduction.  we want to be quiet!
 2009-02-15 16:16:28 +00:00
Harald Welte 940093296e support non-123 ARFCN on nonoBTS 2009-02-15 15:38:42 +00:00
Harald Welte 4f361fcb68 * add commond header file for ipaccess protocol 
* query for more attributes during ipaccess-find
 2009-02-15 15:32:53 +00:00
Harald Welte e1bd2412c2 * use the correct BCCH channel type for nanoBTS 
* remove old code
* ensure that the default BTS type really is BS-11
* document the '-t' commandline argument in the --help message

With this commit, I can get the nanoBTS 900 working with OML and RSL, register
to the network from phones.  Paging is not tested yet, and voice traffic handling
is completely missing..
 2009-02-15 14:40:09 +00:00
Harald Welte 362322ed81 For Phase2 and higher BTS, use the FULL IMMEDIATE ASSIGN INFO attribute, rather than IMMEDIATE ASSIGN INFO 2009-02-15 14:36:38 +00:00
Harald Welte 5c1e458376 Add support for ip.access RSL link on port 3003 2009-02-15 11:57:29 +00:00

* add event-based OML bring-up for nanoBTS
 2009-02-15 03:38:12 +00:00
Harald Welte e0590df524 * extend TLV parser to use a list of TLV type descriptions 
* implement TLV type descriptions for NM
* add operational/administrative/availability state keeping logic to abis_nm
* explicitly print all NACK's in abis_nm
* make sure we produce [not just for BS-11] valid channel attributes

Holger Freyther 49314f6080 [paging] Do not create a request when one is already pending... 
This is removing a memleak, saving some mallocs and a crash
in the timer expired function that attempted to remove the
paging_request from a list it was not in....
 2009-02-14 23:53:20 +00:00
Holger Freyther 2fa4cb5bc9 [paging] Assign the subscriber to the channel first... 
Assign the GSM subscriber to the lchan and then inform
the paging layer and dispatch a signal. This makes sure
that lchan is updated with the right kind of information.
 2009-02-14 23:53:15 +00:00
Holger Freyther 531c0deecb [paging] Fix crash, move_to_next can not be used.... 
move_to_next is using the last_request but we do not have
one... but we know the list is not empty so just pick the
first entry.
 2009-02-14 23:35:09 +00:00
Holger Freyther 36b5d650b8 [signal] Fix misuse of llist_add_tail... 
The to be added llist_head comes first.......
 2009-02-14 23:35:06 +00:00
Holger Freyther 6b2d262888 [nm] Fix the ObjectClass for Set Channel Attribute 
In r308 the enum for the object class was fixed and we
started to send the wrong (0x4) instead of the right (0x3)
object class. Fix that.
 2009-02-14 23:16:59 +00:00
Holger Freyther 7aaf112ba7 [signal] Add consumer of the signal api, inform about paging 
Use the new signaling API in the telnet interface to broadcast
a succeeded or failed paging request.
