SLA Violation Mitigation in Wireless Network Slices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Monitoring and ensuring service-level agreements (SLAs) in wireless communication networks is challenging due to the expansion of bandwidth and user devices, leading to slicing of user devices and stratification of service levels, with existing technologies failing to effectively manage SLA violations and optimize network performance across diverse user equipment.
Innovation Solution
The implementation of a system that includes a network interface, processor, and memory to identify target base stations and slices, send trigger messages for SLA reporting, receive and analyze SLA reports, and determine updated scheduling parameters to mitigate violations, ensuring compliance with SLA constraints by optimizing resource allocation across network slices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network operators provide differentiated service levels to different user slices, then service quality for specific user groups is improved, but monitoring and ensuring SLA compliance becomes more complex
Solution Approach 1:
The patent segments the network into multiple slices with different service levels, and further segments the monitoring system into network-side components (base station, network controller) and user equipment components. Each slice has dedicated SLA parameters and monitoring mechanisms, allowing independent management of service levels without overwhelming system-wide complexity.
Solution Approach 2:
The patent implements a feedback mechanism where SLA reports are continuously collected from user equipment, analyzed by the network controller, and used to generate updated scheduling parameters. This closed-loop feedback system automatically adjusts resource allocation to maintain SLA compliance, reducing the need for manual intervention and simplifying operational complexity.
2Measurement precision
If SLA reporting is implemented for all user equipment, then service level monitoring accuracy is improved, but network signaling overhead and processing load increase
Solution Approach 1:
The patent applies local quality by configuring SLA reporting selectively based on user equipment characteristics, slice requirements, and current network conditions. Not all UEs report all parameters at all times - instead, reporting is tailored to local needs, maintaining monitoring accuracy where required while reducing unnecessary processing elsewhere in the network.
Solution Approach 2:
The patent dynamically changes reporting parameters such as reporting intervals, measured KPIs, and triggering conditions based on network load, slice priorities, and SLA violation risks. This allows the system to maintain monitoring precision during critical periods while reducing processing energy during normal operations through adaptive parameter adjustment.
3Speed
If real-time SLA monitoring is performed, then service level violation detection speed is improved, but system resource consumption increases
Solution Approach 1:
The patent implements periodic SLA monitoring where user equipment measures and reports KPIs at configured intervals rather than continuously. The reporting can be triggered periodically or event-driven (e.g., when thresholds are crossed), allowing the system to maintain fast violation detection capability while consuming energy only when necessary, balancing speed and energy efficiency.
Data Source
AI summary
An apparatus includes a network interface, a processor and a memory. The memory contains instructions, which when executed by the processor, cause the apparatus to identify a target base station and a target slice comprising an electronic device for service level agreement (SLA) monitoring, send, via the network interface to the target base station, a trigger message for initiating SLA reporting by the electronic device of the target slice connected to the target base station, receive, from the target base station via the network interface, at least one SLA report from the electronic device of the target slice, determine an SLA violation level based on the at least one SLA report, determine updated scheduling parameters based on the SLA violation level, and send the updated scheduling parameters to the target base station via the network interface.
