Dynamic DNS Configuration Selection for Edge Computing Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, especially in edge computing scenarios, existing DNS configuration methods fail to optimize latency and routing for user equipment (UE) effectively, leading to suboptimal user experience due to the inability to seamlessly integrate network-provided DNS configurations with local or application-specific configurations.
Innovation Solution
A DNS configuration processing method and apparatus that allows User Equipment (UE) to determine the appropriate DNS configuration by combining network-provided and local DNS configurations, with feedback mechanisms to stop maintaining unnecessary DNS handling rules, ensuring optimal latency and routing based on current application scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the network device provides DNS configuration to the UE, then the service latency is optimized and routing is improved, but the UE cannot respect local or application-specific DNS settings
Solution Approach 1:
The patent implements dynamic DNS configuration selection where the UE can switch between network-provided DNS configurations and local/application-specific DNS configurations based on current conditions. The UE determines whether to use the network-provided configuration or maintain local configuration based on feedback mechanisms and operational requirements, making the system adaptive rather than static.
Solution Approach 2:
The patent allows different DNS configurations to be applied at different levels (network level vs. local/application level) depending on the specific service requirements. Local or application-specific DNS settings can be prioritized when needed, while network-provided configurations are used for general services, creating a differentiated quality approach.
2Productivity
If the UE uses network-provided DNS configuration, then routing optimization is achieved, but unnecessary DNS handling rules are maintained in the network
Solution Approach 1:
The patent implements a feedback mechanism where the UE informs the network device whether it has used the network-provided DNS configuration or maintained local configuration. This feedback allows the network to dynamically adjust its behavior - maintaining DNS handling rules only when needed, thereby reducing unnecessary complexity in the network while preserving routing optimization benefits.
3Reliability
If the network maintains DNS handling rules for all UEs, then service availability is ensured, but network resources are wasted on unused configurations
Solution Approach 1:
The feedback mechanism enables the network to distinguish between UEs that need DNS handling rules and those that don't. By receiving feedback from UEs about their DNS configuration usage, the network can maintain service availability for active users while releasing or deactivating DNS handling rules for UEs that have switched to local configurations, thereby reducing wasted network resources.
Solution Approach 2:
The network can discard or deactivate DNS handling rules for UEs that no longer need them (those using local configurations), while recovering or reactivating these rules when UEs switch back to network-provided configurations, ensuring resources are allocated efficiently based on actual demand.
