Hello Stefan Sperling, Vadim Yanitskiy, Jenkins Builder,
I'd like you to reexamine a change. Please visit
https://gerrit.osmocom.org/12133
to look at the new patch set (#3).
Change subject: Add VTY option to avoid sending empty Full BCCH Info for
disabled SI
......................................................................
Add VTY option to avoid sending empty Full BCCH Info for disabled SI
According to 3GPP TS 08.58 ยง8.5.1 BCCH INFORMATION:
"If the Full BCCH information element is not included this indicates that
transmission of the indicated SYSTEM INFORMATION message shall be stopped."
However, some ipaccess nanoBTS firmware versions are known to not support
some SI elements and also to dislike receiving BCCH Information for those SI,
even if received with empty BCCH Information meaning they should not be used.
Upon receival of this kind of message, nanoBTS sends a Failure Report
with following text:
Type=processing failure, Severity=critical failure, Probable cause=Manufacturer
specific values: Fatal software error, Additional Text=l2_bch.c:1149
****
** l2_bch.c#1149:BCHbcchSItypeValid( prim_p->infoType )
** IPA_SW_FATAL_ERROR
** In task "TRX Proc:L2_BCH" @ (325).
****
This kind of issue only appears with some fw versions, since it's known
to work fine in other ones, so let's not disable this kind of mesage by
default on all BTs of type "nanobts".
Instead, add a VTY command that allows disabling this kind of message in
order to be able to operate those nanoBTS units.
Fixes: OS#3707
