8. LTE CONFORMANCE TESTING
 These sample tests show some of the selected test cases out of 3GPP
spec.36.523.
 The 3GNets team can provide similarly all the test cases in real live
network & LAB.
 The tests results will show if the functional tests are pass/fail and
performance of the Handset and/or Network at various L1, L2, L3 modules
in AS and NAS.
 The report here shows some tests how the Huawei LTE data card has fared
in Airtel’s LTE rel-9 Network.

9. Sample Test Case
Redirection Conformance
UE in E-UTRA RRC_CONNECTED. When { UE receives
RRCConnectionRelease including redirection Information with utra-
CarrierFreq UTRA frequency - then {UE enters RRC_IDLE on UTRA
frequency included in IE redirection Information }

12. • Analysis shows that the UE was supposed to
move to the carrier 10833 ARFCN and that is
an UTRA cell. It was in cell 20 and after the
release it shows that it is now receiving BCCH
of the UTRA cell.

13. A3 Measurement Report
 UE in E-UTRA RRC_CONNECTED & configured for A3. When {
Neighbour becomes offset better than serving } - then { UE
sends MeasurementReport with measId for event A3 }.
RLF & TAU
 UE in E-UTRA RRC_CONNECTED with default bearer established and
radio link failure was detected and UE initiates re-establishment.
When UE receives a RRCConnectionReestablishmentReject - then { UE
goes to RRC_IDLE and trigger TAU procedure in order to recover RRC
connection }
