Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing volume of network events in 5G wireless communication networks, driven by higher numbers of devices and new service types, poses challenges for efficient event reporting, leading to significant server capacity and power consumption, and existing random sampling techniques may filter out problematic communication sessions, reducing anomaly detection efficiency.
Innovation Solution
A method that involves receiving network analytics requests and NF reports to generate and send event reporting requests based on event reporting requirements, capabilities, load, and capacity, allowing for controlled event reporting, including event sampling rates and filter settings, to optimize reporting without overburdening network functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If random event sampling techniques are applied to reduce the amount of data that needs to be analyzed, then the server capacity and power consumption are reduced, but the efficiency of network anomaly detection deteriorates because problematic communication sessions may be filtered out
Solution Approach 1:
The patent changes the parameter of event selection from random sampling to filtered sampling based on event criteria. The network function selects events for reporting based on specific filters and criteria rather than random selection, maintaining anomaly detection efficiency while reducing the volume of reported events to lower power consumption and server capacity requirements.
Solution Approach 2:
The patent extracts only the relevant events that meet specific reporting criteria from the total event stream. By applying filters at the network function level, only events that are likely to be anomalous or of interest are extracted for reporting, eliminating the need to analyze all events while maintaining detection efficiency.
2Reliability
If all network events are reported to achieve high resolution for network analysis, then the anomaly detection efficiency is maintained, but the server capacity and power consumption increase significantly
Solution Approach 1:
The patent changes the reporting parameter from complete event reporting to selective event reporting based on filters and criteria. The network function evaluates events against defined criteria and only reports those that meet the thresholds, maintaining sufficient resolution for anomaly detection while significantly reducing the data volume that requires processing and analysis.
Solution Approach 2:
Instead of reporting all events (excessive action), the patent implements partial reporting where only events meeting specific criteria are reported. This partial action is sufficient to maintain anomaly detection efficiency while avoiding the excessive power consumption and server capacity requirements of complete event reporting.
3Measurement precision
If the event reporting volume is increased to cover more devices and service types in 5G networks, then the network management resolution is improved, but the device complexity and processing requirements increase
Solution Approach 1:
The patent changes the reporting parameter from uniform high-resolution reporting to selective reporting based on event criteria and network function capabilities. By applying filters and selecting events based on specific parameters, the system achieves sufficient management resolution without the excessive processing requirements of reporting all events from all devices and service types.
Solution Approach 2:
The patent segments the event reporting process by applying different filters and criteria to different event types and network functions. Each network function reports events according to its specific capabilities and the relevance of its events, dividing the overall reporting task into manageable segments that reduce total processing requirements while maintaining comprehensive coverage.

AI summary
According to the present disclosure, a technique for controlling reporting of network events by one or more network functions, NF, of a wireless communication network is provided. A method implementation of this technique comprises receiving, from at least one network analytics component, a network analytics request indicative of at least one event reporting requirement of the at least one network analytics component, and receiving, from at least one IMF, one or multiple NF reports indicative of at least one of an event reporting capability, a load and a capacity of the at least one NF. The method further comprises generating an event reporting request based on the at least one event reporting requirement and at least one of the event reporting capability, the load, and the capacity of the at least one NF, and sending the event reporting request to the at least one NF so as to control event reporting by that at least one NF.
