The patent application outlines a system for managing transient roaming and network slicing in real-time distributed mobility management. It involves predicting the travel path of a mobile device using a primary network and identifying secondary networks that will be encountered along this path. The system synchronizes the communication requirements of applications on the mobile device with these secondary networks to ensure seamless connectivity and service continuity.
Transient roaming is a scenario where a mobile device temporarily connects to a different network operator’s public land mobile network (PLMN) while traveling. This system ensures that the mobile device maintains uninterrupted service even when moving between different network operators. The home network handles billing and authentication, while the visited network facilitates the connection, supported by core network components like the Mobility Management Entity (MME) and gateways.
Both 4G and 5G networks support roaming, with 5G offering more advanced capabilities through Non-Standalone (NSA) and Standalone (SA) modes. NSA uses 4G infrastructure for control signaling, while SA relies entirely on 5G infrastructure. Key components like the 5G core and Access and Mobility Management Function (AMF) manage user mobility and session states, ensuring seamless service access during roaming through agreements between network operators.
Network slicing in 5G networks allows operators to create multiple virtual networks on a shared infrastructure. During transient roaming, network slicing ensures consistent service quality by dynamically allocating resources based on location and service requirements. The home network coordinates with the visited network to maintain service slices, ensuring that users experience consistent performance and security, even when roaming.
The system includes a processing device with a processor and memory to execute instructions for predicting travel paths and identifying suitable networks. It synchronizes communication requirements between the home and visited networks, establishing communication sessions for mobile applications. The system supports various access methods and network types, integrating seamlessly with existing infrastructure to provide continuous service across multiple network environments.
