Edge Enabler Server Application Context Relocation Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile edge computing systems, the simultaneous initiation of application context relocation procedures by multiple devices can lead to repeated signaling, increased system load, and disruptions in service continuity, especially when terminals move across different service areas.
Innovation Solution
A method is introduced to coordinate application context relocation procedures across multiple devices, involving the transmission of specific information between terminals, application servers, and edge enabler servers, and the selection of optimal relocation modes based on device capabilities, thereby reducing unnecessary signaling and ensuring service continuity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If application context relocation procedures are initiated by multiple devices simultaneously, then service continuity can be maintained, but signaling overhead increases and system load increases
Solution Approach 1:
The source EES acts as an intermediary that coordinates the application context relocation procedure. It receives relocation requests from multiple devices, manages the relocation process centrally, and sends notifications to prevent duplicate procedures. This mediator approach maintains service continuity while reducing signaling overhead by avoiding redundant relocation requests.
2Quantity of substance
If application context relocation procedures are coordinated centrally, then signaling overhead is reduced, but device complexity increases
Solution Approach 1:
The source EES performs multiple functions: it acts as the primary contact for relocation procedures, manages context information, sends coordination notifications, and handles service continuity. By consolidating these diverse functions into a single multi-functional entity, the system reduces overall complexity rather than increasing it, as each device has a clear, standardized role.
3Adaptability or versatility
If relocation procedures are allowed from multiple devices, then adaptability is improved, but system load increases
Solution Approach 1:
The system allows multiple devices to potentially initiate relocation (excessive action capability) but implements a coordination mechanism that ensures only one actual relocation procedure executes (partial action execution). The source EES receives requests from multiple devices, selects one to proceed, and notifies others to stop, thus maintaining flexibility while preventing excessive system load from duplicate procedures.

AI summary
The present disclosure relates to a communication technique for fusing a 5G communication system with IoT technology to support a higher data rate than a 4G system, and a system thereof. The present disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security and safety related services, etc.) on the basis of 5G communication technology and IoT-related technology. According to one embodiment of the present disclosure, provided is a method of a first server in a wireless communication system. The method of the first server is characterized by comprising the steps of: receiving first information on whether a relocation procedure of an application context can be started from at least one of a terminal and an application server; confirming second information related to the relocation procedure of the application context on the basis of the first information; transmitting the second information to the terminal and the application server; and when it is confirmed that the relocation procedure of the application context is being performed, transmitting an indicator indicating that the relocation procedure of the application context is in progress to the terminal and the application server.
