Worked in Telecom project for the Development of 5G RAN. Currently working for the Centralized Unit (CU) Layer 2, of the 5G Networking system.
Agile Methodology with Jira for work management and git for version control.
Developed and implemented fixes for CU-CP and CU-UP codes.
Developed and tested code for var log traces with NODISCARD functionality for different log levels: ‘FATAL’, ‘ERROR’, ‘INFO’ and ‘WARNING’.
Worked on Handover feature over Xn and N2 interfaces.
Analyzed Wireshark (pcap) logs, obtained from tcp dump.
Component Test Cases in Robot Framework, along with q-tests, All-in-one and End- to-End Testing; Validation through yaml files for the Test Cases
Delivered critical features including Inter and Intradu Handover, CUUP Restart, DPDK logging enhancements, and, contributing to product reliability and scalability.
Conducted end-to-end testing on Test Line setups to validate system functionality and performance across different network configurations.
Client: Dell Technologies
Technologies: 5G NR, OS: RHEL, Windows
Operating System: Linux
Skills: Wireshark, Docker, Jenkins, Git, Git hub, Component testing, VS Code.
Features:
UESIM 3.0
Implemented the code for Uesim3.0 and worked on the throughput analysis of DL and UL data with different time and with different data and also with single UE and Multiple UE on the PAL
Inter-DU and Intra-DU Handover
Designed and implemented handover procedures between Distributed Units (DUs) to ensure seamless mobility and connectivity in the 5G RAN environment.
Optimized handover algorithms to reduce latency and improve network reliability during transitions.
Conducted extensive testing and validation to ensure handover processes met 3GPP standards and provided a smooth user experience.
CUUP Restart Feature
Developed and integrated the Centralized Unit User Plane (CUUP) restart feature to enhance network resilience and fault recovery.
Utilized Data Plane Development Kit (DPDK) for high-performance packet processing and efficient restart mechanisms.
Performed end-to-end (E2E) testing and wraparound testing to validate the stability and robustness of the CUUP restart feature.
Logging and Monitoring
Implemented comprehensive logging mechanisms to capture and analyze network events and performance metrics.
Developed tools and scripts for real-time monitoring and troubleshooting of 5G RAN CU components.
Ensured logs provided actionable insights for network optimization and issue resolution.
Coordinated with other engineers to evaluate and improve software and hardware interfaces.
Tested methodology with writing and execution of test plans, debugging and testing scripts and tools.
