A 5G network architecture with dual UPF configuration enabling active-standby redundancy for enhanced service continuity and reliability.

Patentradars sammanfattning

The invention relates to a 5G core network architecture incorporating a hub-based topology with redundant User Plane Function (UPF) entities operating in active-standby mode. The system employs an Interconnection Control and Relay (ICR) transport channel to manage traffic routing between the gNodeB (gNB), Session Management Function (SMF), and dual UPF instances, with N3, N4, N6, and N19 interfaces managing control and data plane communications. This configuration enhances network resilience by enabling automatic failover between active and standby UPF nodes.
