5G -NEAR RT-RIC

Developed NearRT RIC for 5G networks, incorporating diverse features and use cases to enhance platform performance. This included developing and working on various xApps for real-time network optimization, automated load balancing, and dynamic resource allocation. Implemented advanced features to improve network efficiency, reduce latency, and ensure scalable performance across different use cases.

Software Technology

C, C++, Shell scripting

Role

• Developed and deployed the E2 Connection Update, E2 Removal, RIC Service Query Update, E2 node Configuration Update, Error Indication E2AP and E2SM procedure features in compliance with O-RAN guidelines, following open-source specifications and standards.
• Worked on ASN.1 encoding and decoding APIs, specifically focusing on APER (Aligned Packed Encoding Rules) and UPER (Unaligned Packed Encoding Rules). Also handled ASN.1 file compilation to generate codec files, ensuring efficient serialization and deserialization of protocol messages.
• Worked on delivering use cases such as Traffic Steering with database integration and advanced handover algorithms, ensuring robust and efficient performance.
• Managed SCTP socket API calls for control command transfer and reception between CU/DU and the Near-RT RIC platform, ensuring reliable and efficient communication.
• Worked on CU/DU integration with the NearRT RIC platform, enhancing overall system performance and interoperability between components by using SCTP for CU/DU connections with the NearRT RIC and leveraging RMR and gRPC for communication with NearRT RIC services.
• Implemented an F1AP and NGAP decoder for dynamic data integration to efficiently fetch connected cell data and ID and connected UEs.
• Configured and managed CU/DU simulators compatible with the Near-RT RIC E2-Interface, for optimizing the testing and validation processes.
• Added support for dynamic cell details information at the CU/DU by implementing the E2AP configuration update feature. This enhancement allows for real-time updates of cell-specific details directly from the CU/DU.
• Implemented handling at the CU/DU for multiple subscriptions, RIC service query updates, and error indications, providing robust support for various E2AP message types.
• Added support for E2 connection updates at the CU/DU, facilitating dynamic management of E2 connections for more adaptable and responsive network control.
• Worked on NETCONF to efficiently manage network configurations within the 5G RAN ecosystem, enhancing system control and flexibility
• Worked on integrating and optimizing support for E2SM-KPM, CCC and RC functionalities.
• Implemented advanced features to facilitate the handling of multiple subscription requests within a single request, improving efficiency and scalability.
• Developed and refined E2AP control requests to effectively manage diverse RIC indication data.
