Service Path Availability Detection in 5G Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G systems, there is a challenge in implementing effective service access through 3GPP or non-3GPP networks, as existing methods lack efficient mechanisms to determine and switch between available service paths, leading to potential service disruptions and poor user experience.
Innovation Solution
A service access method that determines the availability of a service path by analyzing receiving conditions of data packets, such as error rates and timing, and switches to alternative paths or reduces load on unavailable paths to ensure continuous and effective service access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a service path is selected for service access without determining its availability, then service access can be initiated quickly, but service disruption may occur due to path unavailability
Solution Approach 1:
The patent applies preliminary action by determining the availability of the service path before initiating service access. The first device sends a first data packet through the first service path to a second device and evaluates receiving conditions (such as packet delivery status, error rates, or acknowledgment receipts) to confirm path availability in advance. This preliminary verification ensures that service access is only initiated through proven available paths, thereby improving service access reliability without significant time penalty.
2Reliability
If multiple service paths are monitored for availability, then service continuity is improved, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the service access system into distinct functional entities: a first device (initiator), a second device (receiver), and potentially alternative service paths. Each path can be independently monitored and evaluated. When the first service path is determined to be unavailable through the data packet receiving condition assessment, the system can switch to an alternative service path. This segmentation allows for independent path management and failure isolation, improving service continuity while keeping the monitoring complexity manageable through modular design.
Solution Approach 2:
The patent implements feedback mechanisms where the second device provides receiving condition information back to the first device regarding the first data packet transmission. This feedback loop enables the first device to determine path availability based on actual transmission results. The feedback principle allows the system to dynamically adjust service access decisions based on real-time path conditions, ensuring service continuity while maintaining relatively simple monitoring through event-driven updates rather than continuous polling.
3Measurement precision
If service path availability is determined through data packet transmission testing, then path availability accuracy is improved, but network load increases
Solution Approach 1:
The patent applies partial action by using minimal data packets (single packet or small number of packets) to determine service path availability rather than extensive transmission testing. The first device sends a first data packet through the first service path and evaluates receiving conditions to determine availability. This partial testing approach provides sufficient accuracy for availability determination without imposing excessive network load or energy consumption, striking a balance between measurement precision and resource consumption.
