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 ATSSS rules, and updates the rules to connect applications to channels that satisfy the required performance using 3GPP and non-3GPP data transmission channels.

Engineering Contradiction Analysis
1Reliability
If users set access network types (Wi-Fi or cellular) on the terminal, then the terminal can establish basic network connections, but the application performance requirements (high-speed, low-latency) cannot be met because users cannot know the characteristics of the access network
Solution Approach 1:
The terminal automatically detects network performance characteristics and selects appropriate data steering modes without user intervention. The system self-adapts to network conditions by monitoring metrics like throughput and latency, then autonomously configures the optimal access network type and data steering strategy to meet application requirements.
Solution Approach 2:
The system continuously monitors network performance characteristics and feeds this information back to adjust the data steering mode dynamically. By establishing a feedback loop between network performance detection and steering mode selection, the system can adapt to changing network conditions and maintain optimal application performance.
2Productivity
If the terminal uses preset access network settings, then the network connection can be established quickly, but the network performance does not match the application requirements (e.g., high-speed or low-latency requirements)
Solution Approach 1:
The data steering mode is made dynamic rather than static, allowing it to change based on real-time network performance characteristics. The system continuously adapts the steering mode to match current network conditions and application requirements, transitioning between different access network types and configurations as needed to optimize data transmission performance.
Solution Approach 2:
The system changes key network parameters (access network type, data steering mode) based on detected network performance characteristics. By dynamically adjusting these parameters according to measured metrics like throughput, latency, and packet loss, the system optimizes data transmission performance to meet varying application requirements.
3Reliability
If the network side delivers generic ATSSS rules, then the rules can be applied broadly, but they do not match specific application performance requirements, causing data packet losses and confusion
Solution Approach 1:
The ATSSS rules are customized for specific applications and their performance requirements rather than being generic. Each application receives tailored steering rules based on its specific needs (high-speed, low-latency, etc.), ensuring that the network configuration is optimally adapted to local application characteristics and performance demands.
Solution Approach 2:
The system pre-configures appropriate data steering modes and ATSSS rules based on detected network performance characteristics before data transmission begins. By establishing the correct steering mode in advance, the system prevents data packet losses and confusion that would occur with mismatched generic rules.

AI summary
A network access method, a network device, and a storage medium are disclosed. The method may include: acquiring target network performance of an application; detecting whether the target network performance of the application matches a data steering mode included in an Access Traffic Steering, Switching and Splitting (ATSSS) rule delivered by a network side; in response to not matching, transmitting a target data steering mode corresponding to the target network performance to the network side, for a device on the network side to update the ATSSS rule according to the target data steering mode; and connecting, in response to receiving an ATSSS rule update success message sent by the device on the network side, the application to a network channel which satisfies the target network performance, where the network channel includes a 3GPP data transmission channel and/or a non-3GPP data transmission channel.
