ATSSS Rule Updates for Application-Aware Network Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network access technologies fail to meet the diverse performance requirements of applications, as users cannot accurately determine the characteristics of access networks, leading to suboptimal data transmission.
Innovation Solution
A network access method that acquires target network performance for applications, detects mismatches in existing ATSSS rules, and transmits a target data steering mode to the network side for rule updates, ensuring applications connect to channels that meet performance requirements through 3GPP and non-3GPP data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users set access network types (Wi-Fi only, cellular only, etc.) on the terminal, then access network selection is simplified, but application performance requirements cannot be met
Solution Approach 1:
The terminal detects application performance requirements and feeds back target data steering modes to the network side. The network side updates ATSSS rules based on this feedback, creating a closed-loop system that adapts to application needs while maintaining user-friendly access network selection
Solution Approach 2:
ATSSS rules act as an intermediary mechanism between user access network settings and application performance requirements. The rules enable dynamic data transmission path selection without requiring users to understand network characteristics, thus maintaining ease of operation while improving application performance
2Reliability
If ATSSS rules are updated frequently to meet application requirements, then application performance is improved, but signaling storms occur
Solution Approach 1:
The terminal transmits target data steering modes only when application performance requirements are not met, rather than continuously updating. This partial action approach updates ATSSS rules only when necessary, improving application performance while avoiding signaling storms from excessive updates
3Manufacturing precision
If terminal settings are aligned with network-side ATSSS rules, then data transmission accuracy is improved, but system complexity increases
Solution Approach 1:
The terminal automatically detects application performance requirements and self-adjusts by transmitting target data steering modes to the network side. This self-service mechanism aligns terminal settings with network-side ATSSS rules without requiring complex manual configuration, thus improving data transmission accuracy while managing system complexity

AI summary
A network access method, a network device and a storage medium. The method in the present application comprises: acquiring target network performance of an application (101); detecting whether the target network performance of the application matches a data guidance policy that is comprised in an ATSSS rule issued by a network side (102); if not, transmitting, to the network side, a target data guidance policy corresponding to the target network performance, so that a device on the network side updates the ATSSS rule according to the target data guidance policy (103); and if an ATSSS rule update success message sent by the device on the network side is received, making the application access a network channel that satisfies the target network performance, wherein the network channel comprises a 3GPP data transmission channel and/or a non-3GPP data transmission channel (104).
