Goal-Driven RAN, Core & Subscriber
Subscriber experience, held as a goal — core, RAN, and edge correlated as one
CraftWorld Mobility is the carrier-grade assurance and autonomy platform for the 5G/4G mobile network — spanning the packet core, the radio access network, network slicing, and the subscriber edge. It unifies the full mobility stack under a single control plane, correlating a core network-function event with its RAN and subscriber impact so experience is measured and defended end-to-end. Operators declare the experience goals they own — session success, call quality, cell availability, and per-slice SLA — and the Ritam AIOps engine holds them true: predicting congestion and quality drops before the customer feels them, and acting through radio and slice adjustments on approval. The platform is multi-vendor and O-RAN-aligned, and runs in production at Tier-1 scale.
Platform Overview
| Domain | Carrier mobility — 5G/4G packet core, RAN, network slicing, subscriber edge |
| Control model | Declare experience goals (session success, call quality, cell availability, per-slice SLA) → Ritam measures & holds them |
| Autonomy posture | Agentic-with-approval — radio optimization actions execute autonomously to hold quality of experience; slice re-provisioning and capacity change is proposed, dry-run, and approved |
| Positioning | Correlates core, RAN, and subscriber as one experience — a core event and the cell it rode are one story, not two tickets |
| Delivery | SaaS or operator-cloud · augments incumbent EMS/NMS |
The Mobility Stack — Layer by Layer
CraftWorld manages five mobility layers, each monitored to KPI level and held to a declared experience SLA:
- Network Slicing — per-slice KPIs (throughput, latency, reliability), slice isolation, per-SLA held continuously
- 5G/4G Core — core network function health, registration success, session-path optimization
- RAN — cell setup success rate, radio resource utilization, self-optimizing network actions, neighbour offload
- Massive MIMO — beam management, beam-failure detection and automatic fallback-beam activation
- CPE / Subscriber Edge — per-subscriber signal trend, bearer continuity, pre-emptive handover preparation
Autonomous Capabilities
Predictive congestion handling — the platform learns each cell's busy-hour load pattern and detects saturation 20–30 minutes ahead — acting through radio self-optimization and resource re-allocation before quality of experience drops.
Slice SLA assurance — each tenant slice carries its own SLA. A latency-sensitive slice breach is pre-empted before it violates the contract, with dedicated resources re-provisioned on approval.
Cross-layer root cause — core, RAN, and subscriber-session telemetry are bound into one causal graph; a core-side failure and the cell it traversed resolve to a single root cause in under 60 seconds.
Beam-failure recovery — a Massive MIMO beam failure is detected and a fallback beam auto-activated before the cell visibly degrades.
Telemetry & Execution
Every automated action — self-optimizing network changes, resource re-allocation, function scaling, slice re-provisioning — is dry-run, approval-gated, audited, and reversible.
