O-RAN Compliant E2 A1 R1 Cloud-Native AI-RAN ready xApp ready rApp ready

RIC-Sphere is BubbleRAN’s O-RAN compliant, interoperable RIC platform that brings fine-grain programmability, automation, and AI-driven optimization to 5G/6G Open RAN and AI-RAN deployments. It combines:

  1. Near-RT RIC for fast control loops down to sub-millisecond scale,
  2. Non-RT RIC for policies, analytics, and AI/ML orchestration,
  3. A Proxy-E2 Agent for legacy RAN adaptation and E2-node emulation,
  4. Plus a reusable ecosystem of xApps/rApps, SDKs, and DevOps workflows.

RIC-Sphere Software Stack!

SMO-Sphere and RIC-Sphere are core building blocks of the BubbleRAN Intelligent Automation Platform. They enhance RAN performance while driving operational efficiencies through cloud-native automation and intelligenace in radio access networks.

Outcome: build and validate closed-loop RAN use-cases faster (slicing, QoS/QoE, mobility, interference management, energy optimization, sensing/localization), and scale from lab experimentation to multi-vendor integration and operational trials—without changing platforms.

Frequently Asked Questions

1️⃣ What makes RIC-Sphere different from other RIC platforms?

RIC-Sphere combines O-RAN compliance, cloud-native delivery, fine-grain programmability, and sub-ms near-RT control in one platform—so you can develop differentiating use-cases (slicing/QoE/optimization and sensing-style workflows) without changing stacks as you scale.

2️⃣ Why does cloud-native deployment matter for a RIC?

Cloud-native deployment supports automated rollout/upgrade, scalable DevOps cycles, and smoother integration with adjacent services and app ecosystems—helping teams iterate faster from lab trials to operational validation.

3️⃣ How does RIC-Sphere support multi-vendor interoperability?

Interoperability is achieved through O-RAN standard interfaces and service models (E2/A1/R1). O1 interfaces is also supported (Experimental feature). Validation can be strengthened using third-party RIC test tooling to support integration and regression testing.

4️⃣ How customizable is RIC-Sphere?

You can extend RIC-Sphere through custom service models, xApps (Near-RT), custom rApps (Non-RT), AI/ML model integration, and service model extensions where deeper telemetry/control is needed.

5️⃣ How fast can we get started and prove value?

Teams typically start from provided workflows, SDKs, and example apps to build a first closed loop quickly, validate interoperability, and then extend toward production-like scenarios with repeatable pipelines.

6️⃣ What business value does Sphere-RIC deliver?

RIC-Sphere helps reduce OPEX and operational complexity by standardizing RAN programmability and automation across vendors, and by reducing integration friction through reusable artifacts and consistent DevOps workflows.
