Harald Welte gerrit-no-reply at lists.osmocom.orgHarald Welte has submitted this change and it was merged. ( https://gerrit.osmocom.org/13558 ) Change subject: MSC_Tests: Add testcase to simulate VLR/HLR failure (SGsAP) ...................................................................... MSC_Tests: Add testcase to simulate VLR/HLR failure (SGsAP) Currently we do not simulate a situation where the HLR is unreachable to the MSC. Lets add a test wehere the HLR is disconnected and an LU via SGsAP is tried. The SGs interface should then carry out a reset procedure.
