Description
The following LCLS tests fail:
BSC_Tests_LCLS.TC_lcls_connect_break
BSC_Tests_LCLS.TC_lcls_connect_clear
BSC_Tests_LCLS.TC_lcls_gcr_bway_dont_connect_csc
The tests fail because is for the same for all three tests:
"Received non-matching ASSIGNMENT COMPLETE"
All three tests expect the following ASSIGNMENT COMPLETE:
14:06:55.266136 10 MSC_ConnectionHandler.ttcn:842 { discriminator := '0'B, spare := '0000000'B, dlci := *, lengthIndicator := ?, pdu := { bssmap := { assignmentComplete := { messageType := '02'O, rR_Cause := *, circuitIdentityCode := omit, cellIdentifier := *, chosenChannel := *, chosenEncryptionAlgorithm := *, circuitPool := *, speechVersion := *, lSAIdentifier := *, talkerPriority := *, aoIPTransportLayer := ?, speechCodec := *, codecList := *, lCLS_BSS_Status := { elementIdentifier := '8D'O, lCLS_BSS_StatusValue := '0001'B, spare := '0000'B } } } } }
For all three tests, osmo-bsc sends the following message:
@BSSAP_Types.PDU_BSSAP : { discriminator := '0'B, spare := '0000000'B, dlci := omit, lengthIndicator := 20, pdu := { bssmap := { assignmentComplete := { messageType := '02'O, rR_Cause := { elementIdentifier := '15'O, rr_Cause := '00'O }, circuitIdentityCode := omit, cellIdentifier := omit, chosenChannel := { elementIdentifier := '21'O ("!"), channel := '0000'B, channelMode := '0000'B }, chosenEncryptionAlgorithm := { elementIdentifier := '2C'O (","), algorithmIdentifier := '01'O }, circuitPool := omit, speechVersion := { elementIdentifier := '40'O ("@"), speechVersionIdentifier := '0000001'B, spare1_1 := '0'B }, lSAIdentifier := omit, talkerPriority := omit, aoIPTransportLayer := { elementIdentifier := '7C'O ("|"), lengthIndicator := 6, ipAddress := { ipv4 := '7F000003'O }, uDPPortValue := 11002 }, speechCodec := { elementIdentifier := '7E'O ("~"), lengthIndicator := 1, codecElements := { { codecType := GSM_FR (0), tF := '0'B, pT := '0'B, pI := '0'B, fI := '1'B, extendedCodecType := omit, s0_7 := omit, s8_15 := omit } } }, codecList := omit, lCLS_BSS_Status := omit } } } }
We can see that the lCLS_BSS_Status is missing. This is why the testcases fail.
Notw: The problem is also reproduceable using the follwing git state, which
is just before the mgw/mgcp_client changes were merged.
