Bundled Audit for Stale Session Bindings in 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication networks face inefficiencies due to stale binding records, which can lead to resource wastage and network errors if not properly cleaned up.
Innovation Solution
A bundled audit system for stale binding sessions is implemented, where a Binding Support Function (BSF) determines potentially stale binding records and issues bundled audit requests to supported Policy Control Functions (PCFs), optimizing the cleanup process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If individual audit requests are sent for each stale binding record, then completeness of audit is improved, but network overhead and processing time increase significantly
Solution Approach 1:
The patent combines multiple individual audit requests into a single bundled audit request that can audit multiple stale binding records simultaneously. The BSF groups binding records by their PCF associations and sends consolidated audit requests, reducing the number of separate network transactions while maintaining complete audit coverage across all records.
2Loss of energy
If bundled audit requests are implemented, then network overhead is reduced, but compatibility with legacy PCFs that do not support bundling is lost
Solution Approach 1:
The system dynamically adapts its audit approach based on PCF capabilities. The BSF determines whether each target PCF supports bundled audit requests and adjusts accordingly - using bundled requests for capable PCFs to reduce overhead, and falling back to individual requests for legacy PCFs to maintain compatibility. This dynamic adaptation allows the system to optimize performance where possible while ensuring universal compatibility.
3Quantity of substance
If stale binding records are not cleaned up, then resource availability is maintained, but network efficiency deteriorates due to wasted resources
Solution Approach 1:
The system performs preliminary identification of stale binding records before they cause significant resource waste. The BSF proactively audits binding records that have become stale due to PCF failures or deletions, detecting and addressing the issue before it impacts network efficiency. This preliminary action prevents the accumulation of wasted resources while maintaining overall resource availability.

AI summary
Various embodiments of the present technology generally relate to systems and methods for efficiently cleaning up resources within a network by bundling binding session audit requests. A binding support function (BSF) may determine support for bundled audit requests and unbundled audit requests at one or more policy control functions (PCFs) associated with potentially stale session binding records at the BSF. Based on audit support function at the PCF, the BSF may determine whether to bundle audit requests together, issue unbundled audit requests, or not issue any audit requests. PCF support for bundled or unbundled auditing may be provided via a network repository function (NRF), via headers in binding creation or update requests, or both.
