MEC Server Reallocation for Mobile QoS
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The MEC architecture faces challenges in ensuring end-to-end quality of service for mobile devices, particularly for vehicles with high mobility, as existing procedures fail to guarantee timely data processing and real-time requirements.
Innovation Solution
A method for reallocating data processing peripheral servers in MEC architecture, where a management unit selects a new server based on measured quality of service thresholds, using deterministic or predictive models, and interfaces with RNIS, LS, and BWMS services to ensure minimum quality of service compliance, while anticipating and accelerating reallocation to avoid service degradation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the standard hand-over procedures are used to select the closest server, then the data transfer time between server and mobile terminal is reduced, but the end-to-end quality of service cannot be guaranteed for high mobility scenarios
Solution Approach 1:
The management unit proactively selects a new peripheral server before the mobile device actually needs to hand over, based on predicted quality of service degradation. This preliminary action allows the system to prepare the optimal server in advance, ensuring continuous quality of service guarantees even for high mobility devices without waiting for degradation to occur first.
Solution Approach 2:
The system implements a feedback mechanism where the management unit continuously monitors quality of service parameters and uses this information to trigger reallocation when thresholds are approached. This closed-loop feedback ensures that quality of service is maintained by adjusting server allocation based on actual system performance and changing conditions.
2Device complexity
If the mobile device remains transparent to server changes, then the device complexity is reduced, but the quality of service management becomes less responsive to actual device needs
Solution Approach 1:
The management unit acts as an intermediary between the mobile device and the peripheral servers. It receives quality of service measurements from the device, processes this information, and makes informed decisions about server reallocation. This intermediary role allows the device to remain simple and transparent while the management unit handles the complex quality of service management and server selection logic.
Solution Approach 2:
The mobile device actively participates in quality of service management by measuring and reporting its own quality of service parameters to the management unit. This self-service approach allows the device to provide feedback about its actual performance needs without requiring complex device-side server management logic, maintaining simplicity while improving responsiveness.

AI summary
A method for reallocating a data processing peripheral server in an MEC architecture includes: a prior step of allocating a current peripheral server to process data for a mobile device, by a management unit, selecting a new peripheral server by the management unit, and notifying peripheral server reallocation to the current peripheral server by the management unit. The selecting is preceded by receiving, by the management unit, of a message dispatched by the mobile device and including a data item representative of a quality of service measured at the level of the mobile device.
