[S] Change in osmo-bts[master]: Store "Channel rate and type" from RSL Channel Mode IE in BTS

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bts/+/33291 ) ( 2 is the latest approved patch-set. No files were changed between the latest approved patch-set and the submitted one. )Change subject: Store "Channel rate and type" from RSL Channel Mode IE in BTS ...................................................................... Store "Channel rate and type" from RSL Channel Mode IE in BTS The RSL "Channel rate and type" field from the RSL Channel Mode IE in RSL_CHAN_ACTIV and RSL_MODE_MODIFY_REQ messages is the only place where the BSC differentiates between a normal TCH and the special TCH modes used in VGCS or VBS. Let's copy this field from the RSL message into the lchan state, so that BTS models can actually (in subsequent patches) reflect it when activating the L1.

[L] Change in osmo-bts[master]: ASCI: NCH / NOTIFICATION support

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bts/+/33289 ) Change subject: ASCI: NCH / NOTIFICATION support ...................................................................... ASCI: NCH / NOTIFICATION support This adds very minimalistic support for notification of VBS/VGCS calls. Minimalistic in that we * only notify via PCH (not via NCH or FACCH) * only include notification in otherwise empty PAGING TYPE 1 This means that notification will cease to work once the PCH becomes too loaded and we never would send otherwise empty PAGING TYPE 1 anymore.
