Hybrid Roaming Steering Solutions: Combining Network and SIM-Based Approaches

In order to maximize subscriber network choices and improve the roaming experience, hybrid roaming steering systems combine the advantages of both network-based and SIM-based roaming steering strategies. In order to impact the roaming network selection, network-based steering depends on signaling in the operator’s core network, typically through SS7 signaling to approve or reject network registration attempts. In contrast, SIM-based steering guides the device in choosing preferred roaming partners on its own by using the Preferred Network List (PNL) that is stored on the SIM or eSIM and updated over the air (OTA). Combining these strategies makes use of their complementing benefits.

Network-Based vs. SIM-Based Steering

Although network-based steering offers instant control and may respond dynamically to network status changes, it often has greater signaling costs and has difficulties with anti-steering techniques. By seamlessly guiding devices to preferred networks based on updated network lists, SIM-based steering lowers signaling load and enhances user experience. However, there may be delays because SIM updates necessitate device reboot or refresh commands. The hybrid model combines the flexibility and reduced cost of SIM steering with real-time control via network steering.

Customization and Adaptability in Hybrid Steering

Operators can customize roaming preferences depending on a variety of parameters, including subscriber profile, location, network performance, and roaming agreements, thanks to this dual approach. Operators can quickly adjust to shifting network circumstances and business agreements without user engagement by upgrading SIM profiles OTA. In the meantime, network steering manages situations when SIM steering might not be sufficient and guarantees prompt application of roaming restrictions.

Enhanced Reporting and Traffic Management

Furthermore, better analytics and reporting are made possible by hybrid steering technologies, which provide more precise roaming traffic control. Operators may improve customer satisfaction, maximize revenue through preferred partnerships, and more evenly distribute load among visiting networks with seamless and reasonably priced roaming connections. Proactive network management is made possible by these analytics, which enable prompt resolution of congestion problems and dynamic traffic flow adjustments. Improved reporting also facilitates better decision-making for partner network negotiations and roaming policy optimization.

Future-Proofing Roaming with Hybrid Solutions

As 5G and IoT ecosystems expand, hybrid roaming steering will eventually enable flexible and fine-grained control over massive global fleets of mobile devices and IoT devices. Because it enables scalable control of different device types and communication patterns over diverse networks, it is crucial for future-proofing roaming strategies. Operators will be able to dynamically manage a variety of connectivity requirements and maximize network performance in real time thanks to this breakthrough. Additionally, it facilitates the effective administration of large-scale IoT deployments and fleets of mobile devices, guaranteeing smooth worldwide connectivity and flexibility in response to changing user needs and technological advancements.

Conclusion Hybrid roaming steering solutions give telecom operators a strong, adaptable way to maximize roaming quality and cost by combining network-based and SIM-based strategies. These technologies improve user experience, lower operating costs, and allow for dynamic reaction to the changing roaming landscape by combining real-time network control with flexible SIM profile management. Hybrid steering will continue to be crucial for providing effective, superior roaming across the globe as connection demands expand and diversify.
