Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network performance monitoring is performed using existing schemes, then network traffic can be monitored, but quality degradation occurs due to congestion
Solution Approach 1:
The patent applies preliminary action by proactively distributing packets across multiple access networks (3GPP and non-3GPP accesses) before congestion occurs. The network entity monitors network telemetry information in real-time and preemptively redirects traffic through alternative access networks when congestion is detected or anticipated, preventing quality degradation rather than responding after the fact.
Solution Approach 2:
The patent segments network traffic into multiple access paths (3GPP access and non-3GPP access) and distributes packets across these separate channels. By dividing the single access path into multiple parallel access networks, the system prevents any single path from becoming congested, thereby maintaining transmission quality.
2Device complexity
If single access network is used for packet transmission, then network configuration is simple, but congestion occurs leading to quality degradation
Solution Approach 1:
The network is segmented into multiple access networks (3GPP and non-3GPP) with separate transmission paths. The network entity configures multiple access networks and distributes packets across them based on network conditions, preventing congestion while maintaining manageable complexity through automated traffic management.
Solution Approach 2:
The system dynamically changes transmission parameters by selecting different access networks (3GPP or non-3GPP) based on real-time network telemetry information. This parameter change allows the system to adapt to varying network conditions and avoid congestion without requiring complex manual reconfiguration.
3Reliability
If multi-access packet distribution is implemented, then congestion can be prevented, but system complexity increases
Solution Approach 1:
The network entity automatically monitors network telemetry information and performs self-service traffic distribution across multiple access networks without requiring external intervention. The system autonomously adjusts packet distribution based on real-time network conditions, reducing the operational complexity despite the increased architectural complexity of multi-access deployment.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring network telemetry information from multiple access networks and using this feedback to dynamically adjust packet distribution. This closed-loop control automates the complexity of multi-access management, allowing the system to maintain transmission quality while reducing manual configuration requirements.

AI summary
A method of a terminal according to an embodiment of the present disclosure may comprise the steps of: receiving, via a first access network from a first network entity performing a user plane function (UPF), a first packet including respective pieces of in-band network telemetry (INT) information of one or more nodes included in a transmission path between the terminal and the first network entity; determining a traffic distribution method on the basis of the first packet including the one or more pieces of INT information; and transmitting a second packet to the UPF via the first access network or a second access network on the basis of the determined traffic distribution method.
