Deferring Load During Peak Periods on Core Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telecommunications networks face challenges in providing reliable and high-quality services during peak periods due to high volumes of sessions, leading to degraded user experiences with slower connections and dropped calls.
Innovation Solution
Implementing a load deferral system that selectively defers certain session management actions by a network function (SMF) during peak load conditions, thereby increasing available bandwidth and resources. This system applies a deferral action policy that includes actions such as stopping charging interactions, using locally stored policies, and modifying message transmissions to reduce load on the core network.

Engineering Contradiction Analysis
1Quantity of substance
If network resources are optimized during peak periods to accommodate high volume traffic, then network capacity increases, but service quality degrades due to resource contention
Solution Approach 1:
The patent applies preliminary action by pre-generating and storing session management messages and charging records during non-peak periods. When peak load occurs, these pre-prepared resources are immediately deployed, allowing the system to handle high traffic volumes without real-time processing delays that would degrade service quality.
Solution Approach 2:
The system dynamically adjusts its operation mode based on detected network load conditions. During non-peak periods, it operates in normal mode performing full session management. During peak periods, it transitions to deferred mode using pre-generated resources, and returns to normal mode when load decreases, thereby adapting network capacity to match demand while maintaining service quality.
2Ease of operation
If session management actions are performed in real-time during peak periods, then service functionality is maintained, but network load increases causing resource exhaustion
Solution Approach 1:
The patent extracts the computationally intensive session management actions from real-time processing during peak periods. By separating message generation and charging record creation into pre-processing steps performed during non-peak periods, the system removes the burden of these operations from peak-time network load while maintaining their essential functionality.
Solution Approach 2:
Session management messages and charging records are generated and stored in advance during non-peak periods. During peak periods, the system simply retrieves and uses these pre-generated resources without performing the intensive generation operations, thereby maintaining service functionality while dramatically reducing real-time network load.
3Productivity
If network resources are allocated for non-peak periods, then resource utilization improves, but network capacity is insufficient during peak periods
Solution Approach 1:
The system uses non-peak periods to pre-generate and store session management messages and charging records, effectively preparing network resources in advance. This allows the same physical resources to serve dual purposes: handling normal traffic during non-peak periods and providing deferred processing capability during peak periods, thereby increasing effective network capacity without additional hardware.
Solution Approach 2:
The system changes the operational parameters of network resources based on time of day and load conditions. During non-peak periods, resources operate in a high-utilization mode performing full processing. During peak periods, the same resources switch to a deferred processing mode using pre-generated data, effectively increasing network capacity to meet peak demand without requiring permanent over-provisioning.

AI summary
The present disclosure generally relates to deferring one or more load actions on a network function, such as a session management function (SMF), while providing access to communication-related services in a telecommunications network (e.g., a 5G mobile network). Systems described herein involve determining whether the SMF or core network of a telecommunications network is experiencing peak load conditions (e.g., a period of high network traffic) and, based on the determined peak load condition, causing one or more processes to be deferred or otherwise modified during the period of peak load. In this manner, the systems described herein preserve as much bandwidth and processing resources as possible in an effort to avoid degradation of communication applications and services, such as during voice and/or audio calls.
