Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional broadband access gateway devices fail to ensure network performance requirements for terminal devices with high performance needs, as multiple devices share networks, leading to inconsistent and unsatisfactory performance.
Innovation Solution
A packet transmission method and system that determines a dedicated sliced network for each terminal device based on its service information, creating an end-to-end tunnel for exclusive use, ensuring the network performance requirements are met by allocating specific SLA levels and configuring interfaces accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple terminal devices share a common network between SF and UP, then network resource utilization is improved, but network performance consistency deteriorates
Solution Approach 1:
The patent segments the shared network into multiple independent sliced networks, where each slice is dedicated to specific terminal devices. This segmentation allows the network to maintain resource utilization efficiency while ensuring consistent performance for each device by allocating dedicated network resources through slicing, directly resolving the contradiction between shared resource usage and performance consistency.
2Reliability
If a dedicated sliced network is allocated to each terminal device, then network performance consistency is improved, but device complexity increases
Solution Approach 1:
The patent introduces a network manager as an intermediary that automatically handles sliced network allocation, configuration, and management. This intermediary abstracts the complexity of dedicated network configuration from terminal devices, allowing performance consistency to be maintained through automated slice management without burdening devices with complex configuration tasks.
Solution Approach 2:
The sliced network architecture provides a universal framework that can serve multiple terminal devices with different performance requirements through a single system. The network slicing mechanism enables one network infrastructure to deliver customized, consistent performance to multiple devices simultaneously, reducing overall system complexity while maintaining performance guarantees.
3Reliability
If network slicing is implemented to ensure performance requirements, then service quality is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic network slicing where sliced networks can be flexibly allocated, adjusted, and released based on real-time service requirements. This dynamic approach allows the system to maintain high service quality by adapting network resources to actual needs while managing complexity through automated, flexible resource allocation rather than static, rigid configurations.
Solution Approach 2:
The patent utilizes parameter changes in network slicing configurations to adapt service quality to different terminal device requirements. By dynamically adjusting slicing parameters such as bandwidth allocation, latency constraints, and priority levels, the system maintains high service quality while managing complexity through parameter-based control rather than structural complexity.

AI summary
A method includes receiving a service request, where the service request includes service information of a terminal device that is to perform access; and determining a first device and a first sliced network based on the service information of the terminal device, where the first sliced network is between the first device and a second device, where the service request is forwarded by the second device, and where the first sliced network transmits a data packet of the terminal device.
