Session Validation Audit Indicators for Lightweight NF Messaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing session validation operations in wireless communication networks, such as those following 3GPP standards, incur significant processing costs and network strain due to the use of full-size messages for auditing stale sessions, which are inefficient and resource-intensive, especially when dealing with large numbers of sessions.
Innovation Solution
Implementing a fast audit parameter or indicator in messaging sessions between Network Functions (NFs) to facilitate the use of lightweight messages for validating session validity, reducing data elements in update requests and responses through handshake operations and custom headers or attributes, thereby minimizing processing and network bandwidth usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If full-size messages are used for session validation requests, then complete data payload is exchanged for thorough validation, but processing cost and network bandwidth consumption increase significantly
Solution Approach 1:
The patent extracts only the essential elements needed for session validation from the complete message payload. Instead of exchanging full-size messages with complete data, the system identifies and transmits only critical validation parameters (such as session identifiers and validity flags), thereby reducing processing overhead while maintaining validation accuracy.
Solution Approach 2:
The message structure is segmented into essential validation components and optional detailed components. The essential portion contains only the data necessary for session validity verification, while detailed payload information is omitted or deferred, allowing the system to process validation requests efficiently without handling unnecessary data.

3Loss of energy
If lightweight messages are used for session validation, then processing cost and network bandwidth are reduced, but compatibility with existing NFs without audit capabilities may be compromised
Solution Approach 1:
The validation request message is designed with a universal structure that can serve multiple purposes. The essential components are sufficient for both lightweight validation scenarios and full validation scenarios, allowing the same message format to be used across different NF capabilities without requiring separate message types or complex negotiation mechanisms.
4Reliability
If audit requests are sent frequently to validate stale sessions, then session validity is maintained, but network traffic and processing overhead increase
Solution Approach 1:
The patent extracts only the essential elements needed for session validation from the complete message payload. Instead of exchanging full-size messages with complete data, the system identifies and transmits only critical validation parameters (such as session identifiers and validity flags), thereby reducing processing overhead while maintaining validation accuracy.

AI summary
Various embodiments herein relate to systems, methods, and computer-readable storage media for implementing audit indications for session validation requests. In an embodiment, a method may comprise operating a Network Function (NF) of a network, including creating a messaging session between the NF and a second NF to facilitate communication service using the network, the messaging session created using a fast audit parameter to establish support by the NF and the second NF for utilizing lightweight messages to audit a validity of the messaging session. The method may further comprise exchanging an update request for the messaging session with the second NF, wherein the update request is processed as a full-size request when the update request does not include a fast audit indicator, and as a lightweight request having less data elements than the full-size request when the update request does include the fast audit indicator.
