Steering of Roaming (IPN)

Intelligent Preferred Network (IPN) is TOMIA’s Steering of Roaming service that helps operators to optimize roaming costs with automation and ensures the best user experience.

Market Challenges

Steering of roaming cannot be standalone but has to be integrated with commercial systems to intelligently recommend and execute network actions that will bring savings and high-quality services.

2G/3G Decommissioning

As operators navigate the shutdown of 2G/3G networks, they must address contingencies related to multiple network technologies and ensure uninterrupted voice service in roaming. In this perspective, the device capabilities must be considered during the steering process. Devices which do not support VoLTE or subscribers who have forgotten to activate it before traveling can get stuck in networks where voice service is unavailable. Operators need to manage these cases or notify the subscriber with instructions on how to activate VoLTE when roaming.

Steering and discount agreements have traditionally been handled by separate teams and independent services with different configuration sets and levels of granularity. While one service calculates traffic distribution based on unique roamers, the other measures additional metrics such as financial performance. This approach can potentially lead to misalignment between business strategy and technical execution, such as delayed steering actions when a commitment is met. In addition to the risk of commitment penalties, the cost for prolonged steering updates is estimated at $380K annually.

Even though the industry has made some progress in measuring Quality of Service (QoS) for roaming services, steering is still fundamentally accomplished based on whether coverage is available. If a high-usage subscriber raises a complaint, the Home operator often prefers to stop enforcing steering policies and allow it to connect to any network available, even if this results in additional wholesale costs. Operators are seeking solutions that go beyond non-coverage issues to improve the user roaming experience.

Operators are moving from one-size-fits-all to individual agreements that address specific IoT (Internet of Things) vertical needs. In addition, with multiple offerings targeting multiple consumer segments, it is imperative to move from a partner-level to subscriber-level control. By zooming into the subscriber-level, roaming managers can define network steering policies for specific segments without affecting others. This allows more flexibility and cost savings for the operator and a better roaming experience for the end user.
