Built-in Lightweight Policy Management ⚖️
Totogi now supports Built-in Lightweight Policy Management as a new module inside CaaS, evolving the platform from an OCS/CHF into a converged Charging + Policy solution. Operators now have the option of implementing high-impact policy rules directly within CaaS, with policy behavior configured in Plan Design without dependence on an external PCF/PCRF.

What’s included
– Built-in Lightweight Policy Management provides 3GPP-compliant policy control capabilities inside CaaS, delivered as a multi-tenant module:
– Native 5G policy control (PCF): Future-proof control over Service-Based Interfaces (HTTP/2 + JSON) for standalone 5G architectures.
– 4G policy control (PCRF): Full LTE policy control via an included Diameter adapter
– Roaming support (home/visited policy scenarios)
Supported interfaces
– 5G (SBI) -> Npcf_SMPolicyControl (PCF–SMF): session policy control
– 4G (Diameter) -> Gx (PCRF–PCEF) via the built-in Diameter adapter
Key features
⚙️ Session-level QoS negotiation: Supports default session QoS confirmation or downgrade at session establishment based on policy/plan constraints. Policies can be updated in response to events such as congestion, threshold crossing, and subscriber/profile changes.
🔄 Dynamic policy updates (event-driven): Dynamically align network resources with business rules. The system automatically confirms or optimizes session QoS based on plan constraints and can trigger real-time updates in response to network congestion or subscriber profile shifts.
🔀 Policy + charging alignment: Policy decisions can be driven by quota/spending limit triggers. The policy module is integrated with CHF using an internal N28-like interface, with charging counters behaving as if the PCF were integrated via N28.
🔔 Policy Event Exposure: Gain deep network visibility by exposing critical policy events to external analytics and management systems.
🛠️Configured in Plan Design: Policy rules are fully configurable in Plan Design, allowing your team to launch new services and iterate on plans without requiring product changes or technical overhauls.
Impact for existing customers
Existing customers that want to adopt Built-in Lightweight Policy Management will need to:
– configure Policy in Plan Design: Quickly define your logic in Plan Design and connect to your existing network interfaces (Npcf/Gx).
– integrate relevant network interfaces (5G: Npcf /4G: Gx)
There is no expected downtime when enabling the module.
What’s coming next
- Dynamic PCC rules
- Rx interface support (as part of the Voice over IMS enablement)
