O-RAN Alliance Technical Steering Committee Structure - A Quick Overview
The O-RAN Alliance is the critical force in Radio Access Network (RAN) technology innovation, and It Keeps evolving automation, cloudification, and disaggregation aspects of ORAN.
Some key highlights:
The Alliance modeled the automation approach with two distinct RAN Intelligent Controllers (RICs): Non-RealTime and Near-RealTime RICs.
Non-RealTime RIC is detailed within the O-RAN Alliance working group 2.
The Near-RealTime RIC and its specifications are covered in working group 3.
The Service Management and Orchestration (SMO) architecture is outlined in working group 1.
The Alliance has been working on interoperable profiles for interfaces specified by 3GPP, focusing on F1, X2, and Xn interfaces and lower layer split (LLS).
The development of interoperable interfaces is covered in working group 5.
Working group 4 is focussing on LLS development.
The O-RAN working group 6, focuses on the O2 interface, which serves as the backbone for deploying, managing, and orchestrating the cloud infrastructure integral to RAN operations.
Second, it focuses on the hardware (HW) acceleration, exploring means of implementation.
A network of 11 work groups (WGs) and three focus groups (FGs) drives the ORAN mission.
The Technical Steering Committee (TSC) guides the technical workgroups responsible for the core O-RAN specifications.
Each technical workgroup plays a pivotal role in shaping the architecture.
The Security Focus Group (SFG) was initially established to oversee security across the open RAN ecosystem. Its responsibility spans all work groups.
While focus groups typically don’t engage in specification work, the SFG is an exception. Given its substantial contributions, it has evolved into WG11 (Security).
