Background Traffic Policy Coordination via Analytics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conflicts between background traffic transfer policies formulated by different policy control network elements for different service network elements lead to network congestion and transmission failures in background traffic.
Innovation Solution
A method where a first policy control network element receives information from a requesting device to determine a background traffic transfer policy for a terminal device, sends this information to a data analytics network element to analyze based on a target policy of another terminal device, and adjusts the policy to avoid conflicts, ensuring non-conflicting policies and preventing transmission failures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different policy control network elements formulate background traffic transfer policies independently for different service network elements, then each service network element can obtain its requested policy, but policy conflicts occur leading to network congestion and transmission failures
Solution Approach 1:
A data analytics network element is introduced as an intermediary between policy control network elements and service network elements. This intermediary collects background traffic transmission data from multiple sources, analyzes it to determine data analysis results, and provides these results to policy control network elements. This mediator enables centralized coordination without eliminating the distributed policy formulation capability, thus resolving the contradiction between policy flexibility and transmission reliability.
Solution Approach 2:
The system implements a feedback mechanism where the data analytics network element continuously collects actual background traffic transmission data, analyzes it, and feeds back the analysis results to policy control network elements. These feedback results include information about transmission timing, data volumes, and successful transmission patterns, enabling dynamic policy adjustment that prevents future conflicts while maintaining adaptability.
2Productivity
If multiple terminal devices transmit background traffic in the same time period according to their respective policies, then each device can transmit its background traffic, but network congestion occurs causing transmission failures
Solution Approach 1:
The data analytics network element performs preliminary analysis of background traffic transmission data before conflicts occur. It determines analysis results that include recommended transmission timing and data volumes based on historical successful transmissions. Policy control network elements use these preliminary results to proactively adjust policies, scheduling transmissions during periods predicted to have sufficient network capacity, thus preventing congestion before it occurs.

AI summary
A method for determining a background traffic transfer policy and an apparatus are provided, to resolve a prior-art problem of a background traffic transmission failure caused by a conflict between background traffic transfer policies formulated by different policy control network elements for different service network elements. In the method, a data analytics network element may determine a background traffic transmission data analysis result of a first terminal device based on target background traffic transfer policies of another terminal device (that is, a second terminal device), and may further enable a first policy control network element to determine a background traffic transfer policy of the first terminal device. Therefore, the background traffic transfer policy of the first terminal device is determined by the first policy control network element with reference to the other terminal devices. In this way, the background traffic transfer policy that is of the first terminal device and that is determined by the first policy control network element does not conflict with background traffic transfer policies of the other terminal devices, thereby avoiding a background traffic transmission failure.
