Change in osmo-bsc[2022q1]: smscb: Always start ETWS timer even in cells without ETWS support

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bsc/+/28017 ) Change subject: smscb: Always start ETWS timer even in cells without ETWS support ...................................................................... smscb: Always start ETWS timer even in cells without ETWS support ETWS is sent over both dedicated channels and broadcast channels. Some BTS models may not support the latter, but it is still useful to start the related timer to ensure bts->etws.active gets set to false after the emergency period has concluded.

Change in osmo-bsc[2022q1]: cbsp: Implement KILL for Emergency Broadcast

laforge has submitted this change.

Change in osmo-bsc[2022q1]: smscb: Don't include extraneous IEs in CBSP KILL COMPLETE / FAILURE

by laforge

laforge has submitted this change. ( https://gerrit.osmocom.org/c/osmo-bsc/+/28015 ) Change subject: smscb: Don't include extraneous IEs in CBSP KILL COMPLETE / FAILURE ...................................................................... smscb: Don't include extraneous IEs in CBSP KILL COMPLETE / FAILURE TS 48.049 states the following rules for the KILL COMPLETE / FAILURE messages: The Number of Broadcasts Completed List IE, if present, contains for each cell the total number of broadcasts of the killed CBS message. The Cell List IE, if present, contains the cells in which the emergency message is successfully terminated. As any message can only be either emergency or CBS, this means that we can (at maximum) have only one of those two IEs in the message. As there is no explicit indication in the KILL whether it relates to CBS or Emergency, we use the "Channel Indicator" IE, which is specified as "only included if the message refers to a CBS message".
