Be able to tune the RACH settings of the BTS via the vty interface,
by default they are initialized to -1 which means we will use the
content of the static array (BTS default) and can be changed via
the VTY interface. I have verified the setting on the nanoBTS with
wireshark and I have tested writing the config file.

This causes some config file breakage but sounds like a much cleaner
approach than to have two separate config variables for this.

Free all allocated channels on the TRX that failed, go through
lchan_free to signal higher layers and then force a reset of
the channel. Make the TRX and TS unusable by setting the operational
set to 0 (not really defined) which should be reset once the
RSL is coming up again.

Keep a static version as the shell script is not dealing well
with branch tags/names containing text.
Resolve merge conflict in the Makefile.am by adding both sides
to the list of sources for the libbsc.a

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.

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"

This library is intended to collect all generic/common funcitionality
of all Osmocom.org projects, including OpenBSC but also OsmocomBB
The library currently includes the following modules:
bitvec, comp128, gsm_utils, msgb, select, signal, statistics, talloc, timer,
tlv_parse, linuxlist
msgb allocation error debugging had to be temporarily disabled as it depends on
'debug.c' functionality which at the moment remains in OpenBSC

For R-GSM900 the channels 955-1023 are within the 900er band. The
System Information Type generation can not cope with these channels yet.

The exact sequence the states the BTS goes through is slightly
different for one of the nanoBTS 139 I have and it needs this
to start.

* On start the vty code will call the abis_nm method and this
will set the administrative state to unlock/lock
* During startup the BTS will report its state as well and would
possible overwrite the set administrative. We are only going
to update the administrative if it was 0 before. This appears
to work on all of my tests. In case this will not be the case
for others we will have to split the administrative into two
sets one for the BTS and one for the BSC.

Tweaking theses can be useful especially tx-integer that influence
both the spread of rach attemps and the delay between two attemps.
Looking up GSM 04.08 3.3.1.1.2 & 10.5.2.29 can help determine good
values. The default are choosed with a wide spacing between attemps
(tx integer = 9 -> T=12 & S=217 (non-combined CCCH/SDCCH) or 115 (for
combined CCCH/SDCCH)). This alleviates the problem of responding to
several RACH attempts by a same MS, allocating several RF channels when
only 1 is needed.

The biggest problem is the moving of the RTP code into
the RSL layer. This may break quite some things...

values that might change at runtime are moved to set_system_infos()
which we might now also call at runtime to update the BTS with
changes in the SI

This introduces a new LOGP() macro together with LOGL_* definition to
support multiple log levels (severities) throughout the codebase.
Please note that the actual logging system does not use them yet,
in this patch we simply introduce the new macros at the caller site.

With this commit, we can successfully hand over a channel from one cell to
another cell. We implement asynchronous intra-BSC (but inter-BTS) handover.
Changes:
* introduce new DHO log category
* extend rsl_chan_activate_lchan() with argument for HO reference
* introduce actual minimal handover decision making in handover_decision.c
* various fixes to bsc_handover_start() in handover_logic.c

allow setting of 'cell reselection hysteresis' and 'rxlev access min' from VTY
for experiments with cell reselection.

Before this commit, OpenBSC used templates for the SYSTEM INFO
1, 2, 3, 4, 5 and 6 messages. Those templates were patched in
various places to reflect the network config like ARFCN.
Now, we actually generate those SI messages ourselves, using
values from the configuration file, and even calculating neighbor
cell lists.
All bts'es that you have configured in OpenBSC will end up in
the neighbor cell list - which should be more than sufficient for
the current small-single-site networks.

- Make sure that on runtime the Radio Carrier can be
locked and unlocked. The vty code calls into the
Abis NM to lock/unlock the channel and the state is
stored there.
- Make sure that on start the Radio Carries remains
offline and we are not starting it. On start the
radio carrier is either locked or unlocked. This means
the RSL will not connect until the RF is unlocked. It
will connect then. To see RSL bringup failures one
needs to parse the RSL nack message.
- When the TRX is locked on startup the RSL link will
only be established after it will be unlocked.
|
|
On cold start the RSL link will not be brought up. Wait for the
Software to be Activated before starting the RSL link. This is
working reliable on the BTS I have tested with.
This is a partial revert of 8406ec2437fcc28906b2085e305d79ae73accc2a and
was discussed on the mailinglist.
