Hands on experience in VoLTE technology acceptance, including:
-
Test Planning – Scheduling optimal test plans that minimize fault impact;
-
Scenario Assembly – Performing platform configuration (core, access and terminal) and service configuration that reflect test scenario parameters;
-
Test Execution – Meticulously going through the multiplicity of paths for test cases, both anticipated problematic and casual ones;
-
Analysis of Results – Gathering evidence of test progress and in depth multi-protocol analysis, using Wireshark. Characterization of degree of compliance with 3GPP and GSMA, as well as service characterization;
-
Fault Description – Technical background, service impact and operation impact;
-
Call Flow design and adaptation – Propose configuration alternatives and design alternative routing of application level traffic;
-
Reporting – Acceptance progress reporting.
Working knowledge of the following network functions:
-
IMS – X-CSCF, ENUM, SBC, MGCF, MGW, AS, MS, HSS, SLF, DRA;
-
LTE – PCRF, P/S-GW, MME, eNB;
-
CS – MSS, MGW, HLR.
Working knowledge of implementation constraints to deploy with the following features:
-
Continuity – SR-VCC from R8 to R10; (theory from R11 to R12)
-
Fallback – CSFB in R4.
