The partnership between Yaana and Cellusys aims to automate the roaming process using open APIs, eliminating manual configuration and improving operational efficiency. Currently, operators manually configure steering based on Yaana's forecasts, but with API integration, this process becomes automated, ensuring accuracy and operational efficiency. Yaana can also benefit from Cellusys's signalling data for better modelling and forecasting, improving overall performance and accuracy.
As roaming complexities grow with 5G, VoLTE, and IoT networks, automation becomes essential for operators. Traditionally simpler, roaming now faces challenges like data usage and network technologies. Event-driven steering by Cellusys tackles this by automating actions based on real-time analytics. This proactive approach ensures prompt issue resolution, enhancing the roaming experience. With preemptive and corrective strategies, operators make informed decisions upfront and adjust dynamically to real-time events. In summary, embracing automation empowers operators to efficiently navigate roaming complexities, ensuring seamless experiences for subscribers while optimizing resources.
Flash calls are emerging as a new challenge for mobile network operators (MNOs). These calls provide a means of authentication similar to SMS one-time passwords but are more cost-effective. However, they pose regulatory and revenue challenges for MNOs, who may not receive payment for zero-duration calls. Despite the controversy, flash call detection is crucial for MNOs to maintain control and security in their networks. Cellusys offers a Voice Firewall solution that provides real-time visibility and control over calls, ensuring network integrity and customer protection against flash call fraud.
