1 hVoLTE: Performed basic power up test cases in hVoLTE mode into VOPS capable region and Non VOPS region.
Performed basic SIP test cases like SIP invite time out, SIP registration, de-registration etc Performed Service Specific Access Class, Mobile data barring related test cases.
Monitored transitions of device between VoLTE and SRLTE states when Entering SSAC Barring for MMTEL Tracking Area and Interaction with VoLTE_hyst timer.
Performed basic network reject silent redial on 1xRTT calling test cases by configuring the DCN.
Performed WPS Calling test cases during idle and active VoLTE call.
Performed basic UDP data performance during active VoLTE call.
Performed some silent redial test cases upon getting service request rejected with EMM cause code 9, RRC connection reject message for MO, RACH failure for MO VoLTE call, on loosing IMS PDN connection and Timer_VZW expiry.
Monitored the behavior of device in loosing LTE Service While on VoLTE call and Acquiring eHRPD and 1XRTT System.
LTE Functionality and Performance: Executed LTE intra and inter band handover test cases like Intra-eNB, X2-based, S1-based, inter MME, with active measurements.
Executed LTE handover with measurements-A5 event based Performed LTE intra and inter band network re-direction test cases.
Performed LTE intra and inter band cell reselection test cases.
Performed basic LTE attach, detach, IMS registration-de-registration, Normal Tracking Area, Periodic Tracking Area related test cases.
Performed LTE data performance in Closed loop, Open Loop, Transmit diversity mode in uplink and Downlink QPSK.
Executed loss of enode b one antenna path attach and rank indication test cases during active file transfer VoLTE: Executed basic IMS registration, IMS re-registration, multiple PDN attach, multi-bearer establishment related test cases.
Performed presence of publication, TTI bundling and ROHC related test cases.
