( https://gerrit.osmocom.org/c/osmo-bsc/+/24891 ) Change subject: RES IND: add VTY: bts / channel allocator avoid-interference (0|1) ...................................................................... RES IND: add VTY: bts / channel allocator avoid-interference (0|1) Store the config option whether the channel allocator should try to avoid lchans with higher interference levels reported in RES IND. The actual implementation of avoiding interference follows in I844494092193811dfd9fa4d52983cbaed0fc9248 Related: SYS#5313 Change-Id: I8b62d0b41ad9e908b27713db9219e3dbc1ebaab7 --- M include/osmocom/bsc/bts.h M src/osmo-bsc/bsc_vty.c M tests/osmo-bsc.vty 3 files changed, 63 insertions(+), 0 deletions(-) git pull ssh://gerrit.osmocom.org:29418/osmo-bsc refs/changes/91/24891/1 diff --git a/include/osmocom/bsc/bts.h b/include/osmocom/bsc/bts.h index 2e88129..992c9bb 100644 --- a/include/osmocom/bsc/bts.h +++ b/include/osmocom/bsc/bts.h @@ -450,6 +450,10 @@ * rather than starting from TRX0 and go upwards? */ int chan_alloc_reverse; + /* When true, interference measurements from the BTS are used in the channel allocator to favor lchans with less + * interference reported in RSL Resource Indication. */ + bool chan_alloc_avoid_interf; + enum neigh_list_manual_mode neigh_list_manual_mode; /* parameters from which we build SYSTEM INFORMATION */ struct { diff --git a/src/osmo-bsc/bsc_vty.c b/src/osmo-bsc/bsc_vty.c index 07c8a9c..9c1813d 100644 --- a/src/osmo-bsc/bsc_vty.c +++ b/src/osmo-bsc/bsc_vty.c @@ -1073,6 +1073,8 @@ vty_out(vty, " channel allocator %s%s", bts->chan_alloc_reverse ?
