AI Technical Summary

Technical Problem

The 5G Service Based Architecture network faces inefficiencies in signaling over interfaces due to large message sizes and increased network overhead, which can impact performance and require additional infrastructure to handle growing mobile broadband usage and new network functions.

Method used

Implementing event-based reporting mechanisms where Network Functions (NFs) send reporting instructions with trigger conditions and cached information, allowing only changed values to be included in reports, reducing message size and overhead.

Benefits of technology

This approach enhances resource-efficient signaling, lowers bandwidth requirements, and improves performance by minimizing unnecessary data transmission between NFs, thereby reducing the need for expanded network infrastructure.

Abstract

There is provided mechanisms for event-based reporting from a second NF to a first NF in an SBA network. A method is performed by the first NF. The method comprises sending reporting instructions of events for a session with the second NF. The reporting instructions comprise a list of triggers conditions for each of the events and information of IEs whose values are cached by the first NF for the session. Each of the trigger conditions is associated with its own set of IEs. The second NF is instructed to provide a report to the first NF when one of the trigger conditions is fulfilled at the second NF. The report comprises values of the set of IEs for the event that caused the trigger condition to be fulfilled. The second NF is instructed to include values in the report of those IEs cached by the first NF only if the values have changed compared to the cached values. The method comprises receiving, on an interface between the first NF and the second NF, the report of the event upon the trigger conditions having been fulfilled at the second NF.
