MEC Geo-Service Subscription via Central Server Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing method for subscribing a mobile equipment to geo-services in an MEC architecture is costly and resource-intensive due to unnecessary communication and high uRLLC resource usage.
Innovation Solution
A method where the mobile equipment only triggers the subscription procedure with the peripheral server if it has information to supply, using a fast messaging channel for notification, thus reducing unnecessary message exchanges and resource consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mobile equipment uses the existing subscription procedure with peripheral server, then the geo-service information can be received, but the uRLLC resources and network communication costs increase significantly
Solution Approach 1:
The mobile equipment performs preliminary actions by sending a registration request message to the central server indicating the types of events it is interested in. The central server then proactively pushes notification messages to the mobile equipment when events occur, eliminating the need for continuous subscription maintenance and reducing energy consumption.
Solution Approach 2:
The invention extracts and separates the event notification function from the traditional subscription protocol. Instead of maintaining continuous subscription states and exchanging multiple messages, the system extracts only the essential event type information and delivers it through simplified notification messages, reducing communication overhead and energy usage.
2Speed
If the mobile equipment maintains continuous subscription to geo-service, then real-time event notification is achieved, but the communication volume and data transmission costs increase
Solution Approach 1:
The system extracts only the essential event type indication from full subscription messages. The notification messages contain only the necessary event type information rather than complete subscription data, significantly reducing communication volume while maintaining real-time notification capability.
Solution Approach 2:
The mobile equipment performs preliminary registration with the central server, indicating its interest in specific event types. This preliminary action enables the system to push only relevant event notifications without requiring continuous subscription maintenance, reducing overall communication volume while preserving real-time speed.
3Reliability
If the peripheral server processes subscription requests from mobile equipment, then service authorization is ensured, but the server computation time and resource usage increase
Solution Approach 1:
The central server acts as an intermediary between the mobile equipment and peripheral servers. It handles the registration request and event type indication, then manages the distribution of notification messages. This intermediary role reduces the processing burden on peripheral servers while maintaining service authorization through centralized control.
Solution Approach 2:
The mobile equipment performs preliminary registration with the central server, which authenticates and authorizes the device before event notifications are delivered. This preliminary authorization step reduces the need for repeated authentication and verification at the peripheral server level, reducing processing time while ensuring service security.

AI summary
The disclosure concerns a method for subscribing a mobile device to information on events from a geo-service hosted on a peripheral server for processing data in an MEC architecture network. The method includes the steps of: sending a registration message to a central server; sending a subscription message, to a type of event, to the peripheral server; receiving a message giving information on an event of the type, the registration message indicating the event type, and sending of the subscription message being subject to the prior reception of a notification message that an event of the type has occurred and that the corresponding information is suitable to be communicated by the peripheral server.
