The sysmobts is now having a SAPI queue with all pending SAPI operations
on the BTS. Add the llist_head to the lchan and make sure it is initialized
by the shared code.
|
|
The token was compared with the configured one but only up to a
user supplied length. Compare the token sizes and then use memcmp
for the actual comparison to make sure to compare the right ammount
of characters.
There is no unit-test but there should be one.

It was possible that the tmp was strduped but not freed, e.g. when
the number of commas was not right. It would evenutally be freed at
the time the cmd is freed thanks to the talloc hierachy.

Linking started to fail for me due the symbol coming from the
vty library and the db code not linking to it.

In order to enable GPRS downlink measurements at mobile, the
network-control-order must be set to nc1.

An ESME can now be configured in the VTY to enable osmocom-extensions,
which will add vendor-specific SMPP TLVs for RxLev/RxQual/ARFCN/IMEI and
transmit power to the SMPP DELIVER-SM message type.

As bsc_gsmnet is NULL at the time we call smpp_openbsc_init(),
we later run into segfaults with subscribers that don't have a
subscr->net set.
However, we cannot delay smpp_openbsc_init() until after
bsc_bootstrap_network(), as we then fail to parse the SMPP specific
VTY/config file options...
|
|
This patch adds a new VTY command "ip.access rsl-ip A.B.C.D" at the
BTS level. If you set this IP address, the BTS will be instructed to
establish the RSL link to the indiciated IP address, rather than using
the same as for the OML link (default).
Use "ip.access rsl-ip 0" to disable the feature.

Inside the SI1 rest_octets we will need to indicate if the ARFCN
is band 1800 or 1900. If the BTS is either 850 or 1900 we assume
we are running a PCS network, otherwise it is a DCS network.
The band indicator is not documented in GSM 04.08 but it is in the
GSM 05.14 version 6.1.0 Release 1997.

The paging structure is still initialized lazily and we attempt
to traverse it before it is ready. The crash was discovered by
Katerina. Removing the lazy initialization will take a bit of work
as the gsm_data_shared is used by the osmo-bts and the OpenBSC but
paging is different.
|
|
We do not want to tell random users to run a network with the
accept-all. This was pointed out by Katerina.
|
|
Katerina pointed out that some nodes are not fully documented and
proposed some messages. The token/timeout messages were correct, I
have modified the other messages. I removed the full-stop from the
PING/PONG documentation as we are normally not using a full sentence.

Describe how we handle/dispatch SCCP messages in the osmo-bsc.

when the SMS code was moved into libosmocore, its logging prefix was
changed from 'sms' to 'lsms', which breaks existing config files.
This introduces a deprecated/hidden vty command to make sure those
config files are still parsed OK, and will simply print a warning
message about the config needing some update.
|
|
The message was corrupt at several points. They are fixed now and
successfully tested.
A default T3122 timer value of 10 is defined by default now. If set to 0,
the reject message will not be sent. Note that when using existing configs
with T3122 value set to 0.

The RF lock excluded BTS was not paged at all. Now forward the
paging message to the handler and call a function that will check
if this LAC can be paged right now. Introduce a new paging method
that allows to page on a dedicated bts, refactor the code to use
this method for paging.
|
|
When introducing the exclude for the BTS lock the RF stayed up but
all connections were immediately released. Optionally pass the BTS
as second parameter and check the exclude bit.
Tested-with: rf-lock-exclude/RFLockExcludeTest.st
|
|
Some BTS might be in locations where they can run all the time,
allow to exclude them from the global lock handling.
|
|
If after release has been sent, the call control layer waits for:
- reception of release complete
- or timeout
- or release of transaction (due to radio link failure)
In this case, an MNCC_REL_CNF is sent to upper layer. The callref must
still exist, so the upper layer can handle this confirm.
|
|
If transaction is destroyed, but callref still exists, the
mncc_release_ind function is called. If the upper layer already sent an
MNCC_REL_REQ, the state N19 was entered. In this case it expects an
MNCC_REL_CNF.

... as an empty system-id would render the openbsc.cfg unparseable on
next openbsc start.

Work on the 'forward' part.. tell the sms queue that something has been
submitted for it..

For PCS1900 the SI1 does not contain the ARFCN of the serving cell.
This is because the arfcn2band method will return GSM_BAND_1800 and
not GSM_BAND_1900. The academic fix would be to set the ARFCN_PCS bit
but this would require increasing the bitvector sizes from 1024/8 to
(0x8000 + 1024) / 8. This would increase the storage size for each
bitvector by three.
It is not possible to have DCS1800 and PCS1900 in one network so we
can avoid increasing the memory usage and check if the ARFCN resolved
to 1800 and then check if the BTS is a 1900 BTS and then claim that
this is compatible.
|
|
This makes reading the condition more easy and allows me to fix it
for GSM1900 more easily and I can remove one level of indention.

The code predates the TLV parser and we were parsing the RLM from the
wrong offset. In general we were using the length of the TLV which
happened to be equal to the T200 indication.
After consulting the RLM cuases not every of them should generate a
BSC_RLLR_IND_ERR_IND as these are forwarded to the MSC as a SAPI reject
right now.
TLV parsing now generates this due a bug in the osmo-bts code:
abis_rsl.c:1605 (bts=0,trx=0,ts=2,ss=0) SAPI=0 <0000> abis_rsl.c:1547 (bts=0,trx=0,ts=2,ss=0) ERROR INDICATION cause=Fraeme not implemented

Returns opearional, administrational state and RF policy
|
|
|
|
For short IP failures we want the RF to stay up and wait for
the re-connect but in case the A-link is gone too long it is
good to switch off the RF and wait for commands to enable it
again.
|
|
|
|
Provide an error message that makes it more clear that the command
is rejected because RF handling is not enabled in the BSC.

Send the current position when the MSC connection is established.
|
|
Use the delayed scheduling feature of the osmo_bsc_rf class to
avoid crashing the site controller of the nanoBTS.
|
|
|
|
Send the signal whenever a MSC appears to be authenticated.

The issue can be reproduced by typing the following 9 or more times.
OpenBSC> subscriber id 2 sms sender id 2 send bla
For some unknown reason the phone sends us a CP-ERROR for a transaction
identifier we have allocated and used but don't remember. Due the way
we use the SMC/SMR we 'establish' the machine and this results in a CP-ACK
being sent out. But the CP-ERROR is not having the content we want for
an establish so we send out a RP-ERROR. This will result in a CP-ERROR
because the phone does not know the transaction...
Avoid the issue by checking the direction of the transaction. If we do
not know the transaction and it is supposed to be allocated by us then
just ignore it and do not create a new transaction.

Make the macros use the cmd->node instead of the data pointer. The
naming of the variable inside the macro already indicates that it
should use the nodes data structure.
|
|
Like with all type unsafe callbacks we will need to cast from
void to the dtype. This addresses some compiler warnings.
Make it possible to only include the control_cmd.h to use the
macros defined in this file.
