  Signaling Gateway (SG) solution via VXSM/MGX Ramped up quickly on CISCO’s complex VXSM Architecture & drafted Integration plan. Pioneered Integration of HSS developed Signaling Plane modules with CISCO’s VXSM Modules by establishing Task Model & Initialization sequence for all SG Modules. Porting HSS developed Signaling Plane modules to VXSM Architecture. Well documented design of RNC & MSC simulators to test SG/MG functionalities.Project was shelved during Design phase as Cisco acquired a company which had a SG solution, but this gave Cisco an insight into HSS capability to design solution. Show less Development of RRC Layer Pioneered integration of RRC module with RLC, MAC and FP layers thereby resolving challenges during integration by finding issues and their resolution. Developed Cell Reconfiguration feature after doing detailed Requirements analysis with multiple stakeholders for API design. Developed Query Interface & re-designed it later using pointers to functions. Leading Design & Coding for Debug module (Error/Traces/Statistics) which assisted in excellent troubleshooting of issues. RRC/SIB version upgrades from R99 to R4 & defined process for subsequent upgrades.  Driving Performance Measurement of Uu i/f after varying various parameters.  Ensuring scenarios identified for Acceptance Testing are executed successfully during System Integration Testing resulting in acceptance of Product by customer. Functional Area Representative for Integration & Testing Process areas during CMMI assessment which got CMMI Level 5 rating to the organization.The project earned Hughes Software Systems CMMI Level 5 and successful implementation of RRC layer was the stepping stone for numerous customer wins in coming years in UMTS/LTE domain which is the core expertise area of organization. Show less Development of Distributed RANAP Outstanding development of Overload Control functionality for DRANAP with most optimal Load distribution algorithm and Unit Testing ensuring 95% code coverage. Finding key issues during Performance testing/analysis of Distributed Iu stack during Dev. phase which accelerated QA cycle. Providing timely support to QA team which resulted in quick closure of issues. Resolving Customer reported queries at highest priority with 0 re-opened issues which won Award for Customer SupportThis was key deliverable for Ericsson which seeded many other opportunities. Show less Development of RANAP Layer Optimized Overload Control functionality by 35% by redesigning the algorithm Took initiative of understanding a new platform independent Porting LibraryPioneered 1st ever integration of RANAP/SCCP layers with this Library thereby resolving integration challenges and later on mentoring other teams for the same. Writing exhaustive Test Plans (Unit Test Plan, Sub System Integration Test Plan and Acceptance Test Plan) which resulted in 15 % less defects in QA cycle w.r.t Project goal Rigorous Testing at all levels (Unit Testing, Sub System Integration Testing, System Integration Testing, Regression Testing and Load/Soak Testing) which resulted in 5 % less defects in QA cycle w.r.t Project goal. Fixed over 20 defects with Zero re-opened defects. Development of peer side RANAP and RANAP User Simulators, to test RANAP layer on N/W side which won Award for Best Design Presentation.Successful implementation of RANAP layer completed HSS’s offering of Core n/w software solution. The same code based was also re-used to reduce time to market RNC side RANAP. Show less
