CTRLXOS
Telecom Control & Service Enablement OS
CTRLXOS by NIVTRIX is a modular telecom control and service enablement platform that brings together subscriber authentication, signaling, policy control, online charging and service delivery within a common software architecture. Designed for telecom operators, ISPs, MVNOs and digital service providers, it supports the integration of network control functions with business applications, subscriber channels and external systems. Deploy individual functional modules or combine them into an integrated telecom control stack according to your network architecture, service requirements and integration needs.
What CTRLXOS delivers
CTRLXOS provides a set of telecom control and service enablement capabilities covering access control, policy enforcement, charging, signaling, subscriber interaction and application integration.
Authenticate
Authenticate and authorize subscriber and device access through supported AAA functions, with RADIUS and Diameter integration options for applicable network environments.
Control
Apply subscriber- and service-level policies through policy control functions, including supported QoS and bandwidth-control integrations.
Charge
Support real-time balance checks, quota reservation and usage-based charging through the Online Charging System (OCS), subject to the applicable charging integration.
Signal
Route Diameter signaling between supported telecom network functions and applications, with configurable peer management and signaling integration capabilities.
Interact & Provision
Support short-code-based interactive USSD services and over-the-air provisioning workflows for supported subscriber devices and SIM-based services.
Integrate
Connect supported CTRLXOS modules with business applications and external systems through a common API gateway and integration layer.
Seven building blocks, one control platform
CTRLXOS combines seven functional building blocks for telecom control, charging, signaling and service enablement. Each module addresses a distinct operational requirement and can be deployed independently or as part of a broader integrated stack, depending on technical dependencies and deployment requirements.
AAA
The CTRLXOS AAA module supports subscriber and device access control across applicable broadband, Wi-Fi, fixed-network and telecom environments. Authentication verifies presented credentials or identities; authorization determines access permissions according to applicable policies; and accounting records supported session and usage information for operational and business-system integration.
RADIUS & Diameter AAA
RADIUS and Diameter-based AAA integration, where supported.
Authentication & authorization
Subscriber and device authentication with access authorization.
Session management
Session management and accounting record handling.
CoA & disconnect
Change of Authorization (CoA) and session disconnect functions.
BNG/BRAS integration
Integration with applicable access-network elements, including BNG/BRAS.
Enterprise application
Centralize supported access-control functions and integrate session information with network operations and business systems.
Diameter
The CTRLXOS Diameter module provides signaling routing and proxy capabilities for communication between supported telecom control, policy and charging applications. Diameter routing directs messages between configured peers according to the applicable routing configuration, and the signaling layer can be integrated with relevant network functions to support communication across the control plane.
Routing & proxy
Diameter routing and proxy functions.
Peer management
Peer configuration and management.
Load balancing
Signaling load balancing, where configured.
Failover handling
Failover handling based on the deployed architecture.
Mediation & message handling
Signaling mediation and message handling.
Application integration
Integration with supported policy, charging and access-control applications.
OCS
The CTRLXOS Online Charging System supports real-time charging workflows for prepaid and other usage-based telecom services. An OCS can participate in service authorization and charging by evaluating applicable balance or quota information, reserving units and processing charging updates through supported integrations. Exact charging behavior depends on the service model, configured rules and interfaces between network functions.
Real-time balance checks
Real-time balance checks against configured account data.
Quota reservation & deduction
Quota reservation and deduction workflows.
Usage-based charging
Usage-based charging support.
Network function integration
Charging integration with applicable network functions.
Gy interface

Billing & BSS integration
Integration with relevant billing and business-support systems. Explore the NIVTRIX BSS/OSS Platform.
PCRF
The CTRLXOS Policy and Charging Rules Function supports centralized policy decision-making for applicable subscriber sessions and services. PCRF functions determine policy rules based on configured conditions, subscriber or service context, and supported integration with network elements. Enforcement is performed by the relevant network functions that consume and apply those rules.
Policy rule management
Policy rule configuration and management.
Subscriber & service policies
Subscriber- and service-level policy control.
QoS & bandwidth policy
QoS and bandwidth-policy integration, where supported.
Gx interface
Gx interface integration with applicable policy enforcement functions.
Charging coordination
Coordination with supported charging workflows.
Enterprise application
Establish a structured policy-control layer aligned to the operator's deployed architecture.
USSD
The CTRLXOS USSD module supports interactive, short-code-based mobile services through supported USSD gateway integrations. USSD enables menu-driven subscriber interactions without requiring a dedicated smartphone application, and operators can configure service menus and connect subscriber requests to relevant service logic or business systems.
USSD gateway integration
Integration with supported USSD gateways.
Short-code menus

Common Central
Common Central provides the shared API gateway and integration layer for connected CTRLXOS modules and external business applications. Instead of implementing every integration as a separate point-to-point connection, organizations can use a common integration layer to manage supported API access, routing, orchestration and service connectivity. Available controls depend on the interfaces and policies configured for the deployment.
