This code simply enables the channel allocator to understand the
dynamic TCH/F / PDCH channel type as used by ip.access nanoBTS.
It does not actually try to switch the dynamic mode, but instead
sends signals to a (not yet present) dynamic switching algorithm.
|
|
We use the (currently unusued) flags member of the bts_trx_ts structure
to track if a dynamic TCH/PDCH is currently on PDCH mode or not.

The logging/debugging code is generic enough to move it into libosmocore
while keeping OpenBSC specific definitions in openbsc itself.
This commit uses the logging support present in libosmocore-0.1.2,
you will have to update your library to this version.

The "sms send pending" VTY command did not work due a mismatch
of types. We are specifying a unsigned long long in the query
and provided DBI with a signed integer type. The result was a
failure do find any information.
Change the API to operate on unsigned long long that is matching
the id of the SMS and the Subscriber and the mismatch with the
query string is gone and pending SMS are sent.

Remove further usage of lchan from the gsm 04.11 bits
|
|
The 08.08 API will interface with the internal BSC code and it is
the boundary between MSC and BSC. So nothing that calls the BSC
functionality should know about lchan or such.
|
|
|
|
Change the MSC transaction code to operate on a GSM Subscriber Connection
instead of the lchan. This will help us to separate the two commands properly.
|
|
Prepare to split the BSC and the MSC part by putting the
MSC data for a connection into a "gsm_subscriber_connection"
struct and renaming the macros.
|
|
the 0.1.1 API is cleaned up and removes all exported global static
arrays (like rlm_cause_strs). There are now proper accessor functions.

|
Together with the previos -e Number option one can easily turn on
debugging without needing to remember the category masks for a quick
check on what is going on.

When we are on a TCH/H or TCH/F always use the SACH for SAPI!=0
for the establishment otherwise it will never be answered. This
can be tested by starting to page with a traffic channel and then
trying to submit the SMS.

The code in 354ef81d8062510765b7280023b3f4ef98d0613a checked
for fd >= 0 but on startup the struct is memset to 0 so this
test is true. Initialize the fds to -1 to make the code work
and be able to handle all ranges of the fd.

|
It didn't really belong into the bsc_init.c... now we could
even easily autogenerate this file.
|
|
|
|
|
|
The copyright/version will be used from within the VTY code
which might be linked into binaries even when bsc_hack.c is
not linked into it.

Attempt to read the three byte IPA header. If we read 0 then
the socket can be closed otherwise we need to read three bytes, if
we don't we do have a failure.
After having parsed the header we need to evaluate the length,
if the length is bigger than would fit into our buffer we will
ignore that and print an error.
This is fixing a crash when the BTS is crashing...
|
|
This code used to be a sleep, it was changed to be a timer by Andreas
but this timer does not seem to have any use. When doing the sw load
this timer is increasing the upload time dramatically, reduce it to
make it work faster.
|
|
Currently one has to put -w in front of -f to really write the
firmware file to disk. Change the config handling to first take
all parameters and then execute on them. This means -f can now
be used with any other parameter.
|
|
We spearate OML/RSL by putting a magic number into the priv_nr. Use
a define instead of ordinary integers.
|
|
Fix a infinite loop when establishing a new RSL connection and the
BSC is identifying itself with a unit id of an already established
RSL connection. The infinite loops happens because we are corrupting
the the linuxlist inside the bsc_fd when registering the bfd twice.
Due the lack of proper authentication favor the new RSL connection
as the real one and close the previous one.
|
|
this creates a hard dependency to a certain base version of the library
|
|
|
|
system_information.c and rest_octets.c don't need a template...

It is now possible to enable/disable GPRS support purely based on
the vty / config file.
|
|
|
|
This new gprs-conf branch is intended to contain everything needed
to configure GPRS in the nanoBTS, but without implementing the SGSN/GGSN
functionality.
The SGSN/GGSN development will happen in a branch based on this branch
called "gprs-sgsn"
|

Use the start address inside the header entry, the start is relative
to the surrounding SDP record which is located in our base offset, when
writing it out also ignore four bytes of something (crc?).
|
|
The first non working version to dump the content of the sdp
to the terminal..
|
|
The sub entry might not be a SDP file so it is best to add the
read entry, add it to the list and then attempt to recursively
parse this one.
|
|
Make the code work/skip the other table and find the entries
at the given offset. This appears to work.
|
|
* The length of the table is not at a fixed position. We will need
to read the offset, seek there, read the data, convert it to the
host endianes.
* Prepare the code to work with offsets of 0...
|
|
* The two dummy bytes appear to be an offset, check that
they are zero and refuse to work when they are not.
|
|
|
|
We have derefenced that way before and would have crashed already.
|
|
* Ignore the value of the field there is no sematnic change
to the content of the file..
