Harald Welte a994a48635 remove misleading debug messages 2009-05-01 15:54:23 +00:00
Harald Welte cf55978e48 make sure we terminate bsc_hack if the OML/RSL listening sockets cannot be created 2009-05-01 15:43:49 +00:00
Harald Welte b463060db9 Fix long-standing bug: nanoBTS now even works after cold boot (first time after power up). 
The problem in the old logic was that we started talking to a given object
(e.g. radio carrier) one we received an administrative state change report.  It
turns out we have to wait for the software activation report instead - and
everything suddenly works.
 2009-05-01 15:43:22 +00:00

Harald Welte 23897662c7 make sure all REPORT type messages have debug statements printing object class and instance 2009-05-01 14:52:51 +00:00
Harald Welte 191280d04b abis_nm wants to use bts->bts_nr (the number of the BTS in the OML link) rather 
than bts->nr (the number of the BTS in the BSC).
 2009-05-01 13:20:04 +00:00

Holger Freyther bcdebbfcab [bsc_hack] House keeping, remove dead code 
This callback is not used from within the paging layer. We do
have a different set of callbacks in place. Remove it here.
 2009-04-19 06:39:29 +00:00
Holger Freyther c2995ea741 [db] Introduce a VLR database here 
This is not a proper VLR yet, specially the (subscriber_)id
used might not be the proper one in a real network.
 2009-04-19 06:35:23 +00:00
Holger Freyther 1d506c8a54 [db] Make the db connection static 2009-04-19 06:35:20 +00:00

Holger Freyther ef7f7ce452 [bsc_hack] Initialize db as part of the network 
Let us establish the rule that there is one DB
per network. This will allow to assign a BTS of
the network to a subscriber that is loaded from
the db across restarts.
 2009-04-19 06:35:12 +00:00
Holger Freyther d4cb79f90d [db] Remove FIXME as it is fixed... 2009-04-19 06:35:05 +00:00
Holger Freyther a1f92f0a43 [subscriber] Introduce subscr_put_channel 
Introduce subscr_put_channel to release a channel and to
allow gsm_subscriber.c to hand this channel to any suitable
pending requests.
 2009-04-12 05:37:52 +00:00
Holger Freyther 4a49e77ff4 [subscriber] Update the current_bts field on imsi detach and LOC accept 
When sending LOCATION UPDATING REQUEST Accept or when getting
a IMSI Detach update the gsm_bts of the gsm_subscriber.
 2009-04-12 05:37:29 +00:00
Holger Freyther 3190a89e38 [calls] Remove a tautology from gsm48_cc_rx_disconnect 
We directly assign the call->state and then check for something
that will never be true, and then immediately put the lchan and
schedule it's disconnect... and then directly after having closed
it down we send a message...

Change this to uncondtionally put down the lchan after having
changed the last(?) command.
 2009-04-12 04:36:16 +00:00
Holger Freyther 0469cf608b [e1] Enable dumping of LAPD frames again 
Kill mi_set_pcap_fd from the header, introduce e1_set_pcap_fd
and call it from bsc_hack.c. Hook into abis_rsl_sendmsg and
_abis_nm_sendmsg for sending and e1inp_rx_ts for reading. It compiles
and should not cause a regression.
 2009-03-31 12:14:16 +00:00
Holger Freyther 66e092bbd6 [e1input] Do not redefine PF_ISDN if it is already defined 
Fix compile warning in e1_input.c
 2009-03-31 12:13:50 +00:00
Harald Welte 7e310b12ff Store incoming SMS into SQL database 
* gsm_util now uses caller-allocated data (rather than callee-allocated)
* correctly parse destination address
* parse (but not transcode) non-default encodings of SMS
* reject SMS to unknown destination number
* resolve target subscriber id and store incoming SMS (without header) in 'sms' table

What we're now missing is the sending part, i.e. a regular task iterating over
all pending SMS and trying to deliver them.  Also, check for pending SMS once
we get a LOCATION UPDATE.

Holger Freyther 3b1f3d0798 [sms] Fix two bugs regarding 7 bit coding... 
- Fix the length (almost)
    - Move the second part by 8 - b_off
      e.g. with (ba) 0x62 0x61 the first bit of
      0x61 goes to the highest on the first byte and
      the second word contains 0x110000...

    - The simple test case is almost passed... just a missing
      character at the end.

    - header the (optional) SMS PDU header
    - payload the payload (utf8), raw data

Harald Welte ba59bafc8e remove subchan_demux debug statements, add DMUX commandline parsing 2009-02-23 00:04:04 +00:00
Harald Welte 7f93ceafef Ignore CONNECTION FAIL INDICATION cause 0x18 to make sure our phone calls survive on BS11. 
Apparently the BS-11 sends soem undocumented cause 0x18 as part of a CONN FAIL IND message
shortly after we establish the call.  If we close the channel, the voice call
is aborted. If we ignore the message, everything just continues to work.
 2009-02-23 00:02:59 +00:00
Harald Welte b49fe96ad6 reduce lag in voice calls by reducing the subchannel muxer tx queue depth to 
effectively three entries.  In the future we should probably think of only
having a one-frame deep queue.

Harald Welte 677c21f4ab add parsing for ip.access vendor specific NM messages 2009-02-17 13:22:23 +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

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 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

  one one 64kBps E1 channel
* add TRAU IDLE frame generation
* terminate bsc_hack in case there is a E1 / mISDN init error
* introduce 'e1_config.c' file with static configuration of our

Holger Freyther e64a7a3c3b [rr] Send a Channel Release before deactivating the channel 
After auto releasing a channel the next paging request will
not be immediately answered. The hypothesis was that we do
not release the channel properly. Implementing Channel Release
of GSM 04.08 should have fixed it, but it didn't. According
to the wireshark dissectors the message is correct though.

- Add the RR cause values to gsm_04_08.
- Implement the Channel Release message
- Invoke the release channel function before deallocating
  the lchan.

Holger Freyther ceb59b72c2 [paging] Move the paging state into struct gsm_bts 
There is a 1:1 relationship between gsm_bts and the paging

Holger Freyther 152a14718a [paging] Use the number of different paging subchannels... 
In our setup (1xCCCH combined, BS_AG_BLKS_RES=0,
BS_PA_MFRMS=0x3 -> 5) we have MAX(1,3-0) * 5 paging
sub-channels. Using this 15 I was able to successfully page
my phone/IMSI (934%15 -> 4).

My confusion is coming from the terms used for paging throughout
the documentation. GSM05.02 6.5.2 talks about "N = number of
paging blocks 'available' on one CCCH = (number of paging blocks
'available' in a 51-multiframe on one CCCH)xBS_PA_MFRMS" which
is already misguiding  and GSM04.08 is talking about number of
different paging subchannels on the CCCH and is providing a
formula.

I deduct that N == number of different paging subchannels on the CCCH
as of GSM04.08 and will simply test this with different IMSIs and
see if I can page them as well.
