Dual-Subscription Traffic Steering and Splitting for Wireless Sessions

The patent segments the wireless connection management by introducing separate policy nodes (first policy node and second policy node) that are specifically designated to handle different wireless subscriptions. This segmentation allows the UE to manage multiple concurrent data sessions across different wireless networks while maintaining organized and distributed control, preventing a single point of failure and reducing bottlenecks in connection management.

The patent introduces policy nodes as intermediary entities that mediate between the UE and the core network for traffic management. These policy nodes receive traffic information from the UE, apply appropriate policies, and forward traffic to the core network. This intermediary layer simplifies the UE's burden by handling complex traffic management tasks centrally, while still enabling enhanced network flexibility and performance through multiple concurrent data sessions.

The patent implements dualsteer capability by designing the network architecture to universally support multiple wireless subscriptions through a standardized mechanism. The policy nodes are configured to handle both single-subscription and dual-subscription scenarios, and the UE can indicate its dualsteer capability during registration. This universal design allows the network to accommodate different subscription configurations without requiring entirely separate systems, thereby reducing overall configuration complexity while maintaining adaptability.
