Core Network Key Activation Triggering for 5G Latency Reduction

The patent applies dynamics by making the key activation procedure optional rather than fixed. The core network element dynamically decides whether to trigger the activation procedure based on actual security requirements and service types. This transforms the static 4G procedure into a flexible 5G mechanism that adapts to different scenarios, reducing unnecessary latency while maintaining security where needed.

The patent changes the parameter of activation necessity from fixed to variable. By introducing indication information that reflects actual security requirements, the system adjusts whether key activation is performed based on service type, terminal capability, and security policy. This parameter change enables the system to avoid unnecessary activation procedures, thereby reducing latency while maintaining adaptability.

The patent extracts the key activation procedure from the mandatory sequence and makes it conditional. By separating the activation decision from the normal connection establishment flow, the system only performs key activation when security requirements dictate. This extraction reduces unnecessary signaling overhead while maintaining security protection where actually needed.

The patent applies partial action by performing key activation only when necessary rather than always. The core network element evaluates security requirements and triggers activation only for services or scenarios that demand enhanced security. This partial approach avoids excessive signaling overhead associated with universal activation while ensuring security where required.
