( https://gerrit.osmocom.org/c/osmo-bsc/+/29422 ) Change subject: add X27 timeout: release lchan that lacks L1 Info ...................................................................... Patch Set 2: (1 comment) Patchset: PS2: Is this behavior defined somewhere in 3GPP specs? Normally the BTS (not BSC) is responsible for declaring a radio link failure event by sending CONN FAIL IND over the A-bis/RSL. Doesn't Ericsson RBS 6xxx send us such a message? The radio lonk failure is declared "based upon either the error rate on the uplink SACCH(s) or on RXLEV/RXQUAL measurements of the MS" (see 3GPP TS 45.008 sections 5.3). The Connection Failure Criterion is configured via the A-bis/OML. -- To view, visit https://gerrit.osmocom.org/c/osmo-bsc/+/29422 To unsubscribe, or for help writing mail filters, visit https://gerrit.osmocom.org/settings Gerrit-Project: osmo-bsc Gerrit-Branch: master Gerrit-Change-Id: I6fb29315568554c8490ee999fcfd1b77d8245389 Gerrit-Change-Number: 29422 Gerrit-PatchSet: 2 Gerrit-Owner: neels <nhofmeyr(a)sysmocom.de> Gerrit-Reviewer: Jenkins Builder Gerrit-Reviewer: laforge <laforge(a)osmocom.org> Gerrit-CC: fixeria <vyanitskiy(a)sysmocom.de> Gerrit-Attention: neels <nhofmeyr(a)sysmocom.de> Gerrit-Attention: laforge <laforge(a)osmocom.org> Gerrit-Comment-Date: Tue, 20 Sep 2022 15:18:26 +0000 Gerrit-HasComments: Yes Gerrit-Has-Labels: No Gerrit-MessageType: comment
