Method for reporting domain-specific error causes in 5G/EPC monitoring configuration failures through multi-node Event Exposure subscription requests with HTTP error codes.

Patentradars sammanfattning

This patent discloses a method for improved error reporting in monitoring configuration across multi-domain 5G networks involving EPC and 5GC domains. A first network node sends an Event Exposure subscription request to a third node (Application Function) with an indication covering both EPC and 5GC domains for multiple monitoring events. The third node forwards the request to a fourth node (UDM or PCF), which returns responses containing HTTP error codes and specific causes of configuration failures. Critically, responses propagate back with domain-specific failure information, enabling precise root-cause identification in complex multi-domain environments.
