Using a distributed architecture, the authentication and billing system cluster is deployed in the carrier's core data center, connecting to the carrier's OCS system to process top-up and bill payments. Deep integration with the carrier's SMS system allows users to complete a secure and convenient identity authentication process via a unified portal page using SMS verification codes.

In addition, the system collaborates with third-party broadband remote access servers (BRAS), third-party authentication systems (RADIUS), and the authentication gateway of our subsidiary, Anlang, to form a complete carrier network access control system.
