Mobility Management Entity Cross-System Terminal Event Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently managing terminal event notifications when a terminal moves between different communication systems, such as 4G and 5G networks.
Innovation Solution
A communication method and apparatus are introduced, where a first mobility management entity receives event information from a unified data management function entity to identify terminal events. When a terminal is unreachable, the entity activates the corresponding terminal event, and upon becoming reachable, it sends a terminal event report to the subscribed application function entity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal event notification mechanism is implemented in a single communication system (4G or 5G), then the terminal event can be monitored and reported within that system, but the mechanism fails when the terminal moves between different communication systems
Solution Approach 1:
The patent creates a universal terminal event notification mechanism that functions across multiple communication systems (4G and 5G). The AMF entity is designed to handle both 4G and 5G terminal events through unified event information structures and standardized notification procedures, making the system adaptable to different communication technologies while maintaining reliable event monitoring and reporting
Solution Approach 2:
The patent introduces an AMF entity as an intermediary between the terminal and application function entities in cross-system scenarios. The AMF receives event information from unified data management, monitors terminal events across 4G and 5G systems, and forwards notifications to subscribed application entities, enabling seamless cross-system event notification without requiring system-specific implementations
2Stability of the object's composition
If event information is maintained in a unified data management function entity, then event context can be preserved during handover between systems, but the complexity of event information management increases
Solution Approach 1:
The patent extracts event information management from individual system-specific management entities and consolidates it into a unified data management function entity. This centralization preserves event context consistency during handovers while simplifying the overall system architecture by having a single point of truth for event information, reducing the complexity distributed across multiple entities
Solution Approach 2:
The patent establishes event information in the unified data management function entity before terminal handover occurs. By pre-configuring and maintaining event context in advance, the system ensures seamless continuity during handover without requiring complex real-time synchronization or re-negotiation mechanisms, thereby reducing operational complexity
Data Source
AI summary
This application provides a communication method and apparatus. A first mobility management function entity may receive event information from a unified data management function entity, where the event information indicates a first-type terminal event. Therefore, when a terminal apparatus is reachable, the first mobility management function entity may send, based on the event information, a terminal event report to an application function entity that subscribes to the first-type terminal event, thereby improving pertinence of sending the terminal event report.
