Efficient and secure Subscriber Data Management thanks to a modern WebGUI_

Subscriber Data Management in telecommunications – a complex challenge

Maintaining these massive volumes of data within highly interconnected and often heterogeneous system landscapes requires not only the utmost precision, but also uncompromising security standards. Because direct modifications reach deep into the operational network layer, careless errors can quickly lead to service outages or compliance risks. The cronn WebGUI makes SDM accessible to non-tech employees and lowers the effort required of administrators and IT staff.  

The challenges

Some of our customers in telecommunications use Nokia’s CNTDB (Nokia One-NDS) to manage mobile and fixednet subscriber data, as well as non-subscriber related (NSR) objects. This platform is typically operated via the complex SPML and DSML interfaces of the Provisioning Gateway (ProvGW) and does not provide a graphical user interface for administrators by default. Precise modifications, additions, or deletions must be executed via SOAP requests, which requires deep technical expertise.

The challenge was to implement a solution that allows less technical staff, such as customer care agents, to safely and intuitively edit these sensitive data sets. At the same time, strict requirements like multitenancy, isolation of IMSI/MSISDN ranges, and rigorous audit and security standards (such as digitally signed X.509 requests and TLS) had to be seamlessly enforced.  

cronn’s WebGUI: A product for modern SDM

To meet these requirements, cronn implemented its proprietary software product, cronn WebGUI, within the customer’s system environments. The application acts as an intelligent and user-friendly web interface between the operators and the provisioning gateways.

• Modern user interface: The React-based UI with custom-built editors allows non-technical users to search, read, and edit attributes for subscriber and NSR objects.
• Secure Authentication & Multitenancy: Integration with the company’s internal Active Directory established a fine-grained, role-based access control system. Permissions can be configured down to the attribute level. Furthermore, the system architecture natively supports multiple isolated tenants and provisioning gateway instances.
• Automation of Common Business Processes: Complex multi-step SPML adjustments (including multi-SIM support) are bundled into a single, simple view. Users can execute these without needing deep knowledge of the underlying data model.
• Cloud-Ready Container Deployment: The architecture, built on the newest Java version and Spring Boot, was delivered as a pre-configured Docker container, ensuring smooth and consistent deployment into the production infrastructure.  

Customer Benefit

By introducing the cronn WebGUI at our customers in telecommunications, operational workflows in Subscriber Data Management were significantly accelerated. The intuitive interface empowers users without deep SPML knowledge to execute complex provisioning tasks accurately and autonomously.

Thanks to comprehensive audit trails and strict Active Directory integration, the highest compliance and security standards have been maintained consistently. Additionally, a built-in provisioning-gateway-simulator gives development and test departments the ability to safely simulate interfaces and data models without affecting production customer data.
