A logical function that enables non-real time control and optimization of RAN elements and resources. The four key features includes-
- Centralized Monitoring across Multiple Zones: Non-RT RIC with its distributed Architecture supports monitoring of multiple zone operations via a Centralized User Interface (CUI)
- Operational Management via Visual Indicators: Network Operators can manage their day-to-day operations through the Visual Indicators in Non-RT RIC Dashboard
- Complete Application Life Cycle Management (LCM): STL Non-RT RIC rApp Application Life Cycle Management (LCM) supports complete lifecycle of any 3rd Party rApp from Registration → Deployment → Monitoring → Upgrade → Downgrade → Removal
- Automated Installation: Enables cloud native deployment of micro services
a2. RAN Operations & Management (RAN O&M)
RAN OAM (Operations and Management) is responsible for the management of the elements under its span of control through the STL OAM GUI. Below are the three key features:-
- Vendor Agnostic Service: Management operations and/or notifications that is agnostic about the entities managed. For example, operations for creating, reading, updating, and deleting managed object instances
- Network Resource Model: It refers to management information represented by information models representing the managed entities
- Managed Entity: It refers to management information represented by information models representing the managed entities
a3. RAN Domain Orchestrator (RAN DO)
STL RAN Domain Orchestrator (RAN DO) will support such as Infrastructure Management, Site Registration Function, Image Inventory Management, Platform Installation, Location and Topology Management. It supports three key features
- RAN NSSMF (Network Slice Subnet Management Function)
- NF Orchestration
- Cloud infrastructure management and operatio
b. Near-Real Time RAN Intelligent Controller (Near-RT RIC)
Near-Real Time RAN Intelligent Controller (Near-RT RIC) is an O-RAN compliant logical function that enables near-real-time control and optimization of RAN elements and resources via fine-grained (e.g., UE basis, Cell basis) data collection and actions over E2 interface
- Network control back to operators: RIC with its standardized open interfaces gives the control of RAN optimization back to operators and enables them to host third party xApps
- Improves RAN performance: RIC effectively balances the RAN load and hence alleviates network congestion
- Quick enablement of new services: Separation between STL Near-RT RIC platform and xApps helps in quick enablement of new service
- Supports low latency applications: Fine time granular control loops across L3 to L1 helps in various dynamic situations like mobility, scheduling, and load balancing
- AI/ML Driven Network Control: Enables data driven optimization by supporting operator's RAN data to deploy AI/ML models
- Pre-O-RAN Support: STL Near-RT RIC can be deployed in both brown and/or green Fields
