- Added function "gsm340_scts" to decode the service center time stamp
into a UTC/GMT timestamp
- in function gsm340_validity_period: can now decode validity period
format absolute.
In the case a transaction has been already scheduled return 0 was
called but the subscriber and transaction would leak. Fix it by
calling subscr_put and trans_free.
After claiming the channel also remove the reference on the subscr.
This is confirmed by looking at the source of their dissector.
The length can go up to 273 bytes apparently (again, according
to the source of their dissector).
Keep track of which SAPIs have been established either by the
BTS (from the MS) or by us. This can be used by the on-waves
BSC code to figure out if a new request should be made.
Be able to send RR CHANNEL MODIFY from the BSC/MSC code
as well. Move the method that knows about the IPAccess RTP
and issues the "bind" to the utils tool
Add code to generate an assignment command for a given lchan. It
is expected that the lchan is modified already and the mode will
be picked up from their. Currently only the mandantory items
are supported.
ipaccess-config stopped working after the introduction of
multi-TRX/RSL stream id support in commit 8175e95222.
Set the oml_tei to 0xff by default and add an option to set
a different stream id.
- Improved handling of extension-number string (as per review)
- Guard against a buffer-overflow if mobile sends a too-long USSD
- declare some function-parameters const
- fix gsm_ts_name function to display the right BTS number (bts->nr rather than bts->bts_nr)
This patch removes the need of static global variables and introduces a new,
caller-allocated 'struct ussd_request' that needs to be passed to the various
functions.
This is needed when you need to manually parse TLV blocks
that don't follow the logic supported by tlv_parse but you
still want to rely on working code and not fiddle with details.
bsc_init.c still contained a hard-coded channel configuration,
i.e. CCCH_combined on TS0 of C0, and TCH/F on all other channels.
Now it correctly uses the value as specified in the config file.
If we have a dynamic TCH/F / PDCH channel configuration, then
we can either ACTIVATE CHANNEL it for a TCH/F, or we need to send
this vendor-specific PDCH ACTIVATE command to use it as a PDCH.
As opposed to a fixed configuration, this allows an intelligent
BSC channel allocator to use otherwise idle channels as PDCH
as long as no more TCH's are needed.
Since TS 12.21 implements only SET ATTRIBUTE for some object classes,
ip.access had to extend it to be able to set attributes on arbitrary
objects. We now introduce a function implementing that message.
Supporting GPRS means we have a number of additional OML objects to
deal with. We need to extend our gsm_bts structure to at least
include the nm_state for each of those objects.
Tag-variableLength-Value is an encoding scheme used in the GPRS NS
and BSSGP protocols, where the length value can be 8 or 16 bits,
depending on actual demand.
