Harald Welte f8d31a7d31 * 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 f9bb68cd37 fix the parsing of the 'normal' availability status 2009-02-18 03:43:01 +00:00
Harald Welte 34e106bf45 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 607579991f "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 55f1c5230e 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 a8685781bf use official TCH/F for initial channel modes rather than BS-11 specific 0x09 2009-02-18 03:37:20 +00:00
Harald Welte 06569326b4 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 ded8d686f5 * 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 7bad70cedb #defines for GSM48 channel modes 2009-02-18 03:28:01 +00:00
Harald Welte 73cd2d875e add DMUX debug prefix 2009-02-18 03:27:39 +00:00
Harald Welte a2addaf03e * 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 95ad2750f2 * use DEBUGP in TRAU frame code 
* make sure we actually set 'spare' bits to 1

Harald Welte d9edbd31f3 strip mISDN hardware header before putting B-channel data into subchannel demuxer 2009-02-17 19:02:29 +00:00
Harald Welte d200ba0e3d 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 4fc6a81938 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 44543bf06a correctly print IPAC_CONNECT_ACK debug statement 2009-02-17 15:29:58 +00:00
Harald Welte 52b3b72da2 various CC updates: 
* correctly lchan_put the second lchan of a call at teardown

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

Harald Welte 103a4156ef add parsing for ip.access vendor specific NM messages 2009-02-17 13:22:23 +00:00
Harald Welte 1da5d2346b add bits and pieces of documentation 2009-02-17 02:02:14 +00:00
Harald Welte 933351f979 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 c538651196 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 6a7c1ec3bc forgot the header files in last commit. sigh. 2009-02-16 22:53:52 +00:00
Harald Welte fbfd7eaa88 * 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 a7e7ff5bbe 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 b8ef4e4d55 * 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 3d566d7b3f introduce msgb_l2len() function 2009-02-16 21:09:34 +00:00
Holger Freyther 70cf9d20ef [sms] Send a notification on incoming SMS

on incoming SMS.
 2009-02-16 19:07:18 +00:00
Harald Welte b656f3ab87 introduce msgb_l3len() function 2009-02-15 17:18:37 +00:00
Harald Welte 1912f806ac * 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 24246825ca * 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 56113ebac5 support non-123 ARFCN on nonoBTS 2009-02-15 15:38:42 +00:00
Harald Welte d07d878c59 * add commond header file for ipaccess protocol 
* query for more attributes during ipaccess-find
 2009-02-15 15:32:53 +00:00
Harald Welte 952ff16e74 * 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 6aa4bae607 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 e3767a4dea 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 896da62528 * 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
 2009-02-15 03:34:15 +00:00
Holger Freyther aad5163f59 [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 576e4b5d58 [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 dcefb82258 [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 bd4dba8610 [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 4a869f8b24 [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 39bf3eb427 [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.
