fixeria has submitted this change. ( https://gerrit.osmocom.org/c/osmo-ttcn3-hacks/+/28092 ) Change subject: bsc: test lchan rel during LCS Loc Req ...................................................................... bsc: test lchan rel during LCS Loc Req Test this scenario: Emergency call is started; Location Request is started to locate the emergency; lchan releases early for any reason; (Do not send Clear Request immediately); Location Request is completed, locating the emergency.
