Mobile Network DNS Settings with Protected Edge Application Discovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In Edge Computing deployments, existing technologies face challenges in ensuring that Domain Name System (DNS) settings provided by mobile networks are not overwritten by user preferences, which can compromise service-level agreements (SLAs) between mobile network operators and application providers, leading to unreliable DNS resolution.
Innovation Solution
Enhancing User Equipment (UE) operating systems to manage and store multiple DNS settings, allowing applications to utilize the original mobile network-provided settings independently of any changes made to the OS-level settings, thereby ensuring compliance with service-level agreements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the operating system allows users to configure and overwrite DNS settings, then user control and adaptability are improved, but the reliability of service-level agreements is compromised because mobile network-provided DNS settings can be overwritten
Solution Approach 1:
The patent segments DNS settings into two distinct copies: a first copy that preserves the original mobile network-provided DNS settings for application use, and a second copy that allows user configuration and overwriting for OS-level use. This segmentation enables both user control and service-level agreement compliance to coexist by isolating the two functions into separate data structures.
Solution Approach 2:
The patent applies local quality by assigning different properties to different parts of the DNS settings system. The first copy of DNS settings is made immutable and protected from user changes to ensure service-level agreement compliance, while the second copy is made mutable and accessible to users for customization. Each copy serves its specific purpose with appropriate access controls.
2Reliability
If the operating system stores and manages multiple DNS settings, then reliability of Edge Application Server discovery is improved, but device complexity increases due to additional storage and management requirements
Solution Approach 1:
The patent divides DNS settings management into two separate stored copies with distinct purposes. The first copy is dedicated to Edge Application Server discovery and is protected from modification, while the second copy handles general OS DNS resolution and user customization. This segmentation simplifies management by clearly defining the role of each copy and implementing targeted access controls.
Solution Approach 2:
The patent creates a copy of the mobile network-provided DNS settings rather than allowing direct modification of the original. This copying approach preserves the authoritative DNS settings for Edge Computing services while creating a separate instance that can be safely modified for other purposes without affecting service reliability.
3Measurement precision
If applications use the original mobile network-provided DNS settings, then Edge Application Server discovery accuracy is improved, but ease of operation is reduced because users cannot modify DNS settings for all applications
Solution Approach 1:
The patent segments the DNS settings system into application-specific DNS resolution (using the first copy for Edge services) and OS-level DNS resolution (using the second copy for general purposes). This allows applications requiring high precision DNS resolution to use the protected first copy, while users retain full configurability of the second copy for their convenience needs.
Solution Approach 2:
The patent applies different quality characteristics to different DNS resolution paths. Applications performing Edge Application Server discovery use the high-precision, immutable first copy of DNS settings, while general OS and user applications can utilize the flexible, user-configurable second copy. Each path has the appropriate properties for its specific use case.

AI summary
The present disclosure relates to Edge Computing enhancements by provisioning applications with mobile network provided Domain Name System (DNS) settings. In one embodiment, a method performed by a User Equipment (UE), which supports an Edge Application Server (EAS) discovery procedure with an Edge Application Server Discovery Function (EASDF), includes receiving a DNS setting provided by a mobile network, and storing a first copy of the DNS setting provided by the mobile network as a first DNS setting and a second copy of the DNS setting provided by the mobile network. Herein, the stored first DNS setting is not impacted by any changes made to the second copy of the DNS setting provided by the mobile network.
