Mobile Edge Platform Switching for Service Continuity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service quality does not meet requirements when user equipment performs access network device switching in mobile edge computing, affecting user experience and service continuity.
Innovation Solution
A mobile edge platform switching method where a second mobile edge platform receives an application identity from a first mobile edge platform, determines a target application instance, and sends a switching notification message to instruct the target application instance to provide service to the user equipment, ensuring low-latency and high-bandwidth service by synchronizing context information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If access network device switching is performed to improve network connectivity and service availability, then service availability is improved, but service quality deteriorates due to potential service disruption and latency increase
Solution Approach 1:
The target MEC platform performs preliminary actions by pre-establishing application instances and preparing service resources before the actual switching occurs. When switching is triggered, the target platform already has the necessary application instances ready, enabling seamless service continuation without interruption or significant latency.
Solution Approach 2:
The patent introduces a service continuity mechanism as an intermediary that coordinates between source and target MEC platforms during switching. This intermediary ensures proper context transfer, maintains service state consistency, and guarantees quality of service parameters are preserved throughout the switching process.
2Reliability
If application instances are deployed on multiple mobile edge platforms to improve service redundancy, then service redundancy is improved, but system complexity increases due to coordination requirements between platforms
Solution Approach 1:
The patent implements feedback mechanisms where the target MEC platform receives status information from the source platform and provides confirmation of successful service takeover. This feedback loop enables automatic coordination, resolves conflicts, and simplifies management by allowing platforms to operate semi-autonomously while maintaining synchronization.
Solution Approach 2:
The system segments service functionality into independent application instances deployed on different MEC platforms. Each platform manages its own local instance independently, reducing coordination complexity. The segmentation allows failover to occur at the instance level without requiring full system coordination.
3Stability of the object's composition
If context information synchronization is performed during platform switching to ensure service continuity, then service continuity is improved, but information loss may occur during the transition process
Solution Approach 1:
The patent ensures continuity of useful action by maintaining active service connections and state information throughout the switching process. The target platform continues processing service requests without interruption, and context information flows continuously from source to target platform, preventing information loss even during transition.

AI summary
The present disclosure relates to a mobile edge platform switching method. In one example method, an application identity of a source application instance is received by a second mobile edge platform from a first mobile edge platform. The first mobile edge platform provides a service for the source application instance. The source application instance provides a service for a user equipment. A target application instance of the user equipment is determined based on the application identity. The application identity of the source application instance is the same as an application identity of the target application instance. The second mobile edge platform provides a service for the target application instance. A switching notification message is sent by the second mobile edge platform to the target application instance. The switching notification message is used to instruct the target application instance to provide a service for the user equipment.
