Terminal Monitoring Synchronization Across Network Handovers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current terminal monitoring systems fail to maintain continuous monitoring when a terminal is handed over from one network to another, as monitoring information is not transmitted between networks.
Innovation Solution
A terminal monitoring information synchronization method and system that uses an information sharing network element to receive monitoring requests from a content server, determine if the target network supports the monitoring information, and send this information to a mobility management network element in the new network, ensuring continuous monitoring during handovers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal monitoring information is configured in a single network, then the monitoring system is simple and easy to manage, but terminal monitoring cannot be kept continuous when a terminal is handed over from one network to another
Solution Approach 1:
The patent introduces an information sharing network element as an intermediary between the content server and mobility management network elements. This intermediary receives monitoring requests, retrieves monitoring information from a database, and forwards it to the appropriate mobility management network element in the target network during handover, thereby maintaining monitoring continuity without requiring direct complex interactions between all network components
Solution Approach 2:
The patent divides the monitoring system into distinct functional modules: a content server that initiates monitoring requests, an information sharing network element that manages information retrieval and transmission, a database that stores monitoring information, and mobility management network elements that execute monitoring in specific networks. This segmentation allows each component to have a specialized function, improving reliability while keeping individual components manageable
2Reliability
If monitoring information is not transmitted between networks during handover, then the system operates independently in each network, but terminal monitoring becomes interrupted
Solution Approach 1:
The patent implements preliminary action by having the information sharing network element retrieve and prepare monitoring information from the database before the handover is complete. The monitoring information is obtained in advance and stored temporarily in the information sharing network element, ensuring that when handover occurs, the information is already ready for immediate transmission to the target network's mobility management element, preventing any information loss or monitoring interruption

AI summary
A method includes processing, by an information sharing network element executed by a processor, a monitoring request received from a content server to determine whether a handed-over-to network supports monitoring information included in the monitoring request. The monitoring information is associated with a terminal that is in one of a first network or a second network and is handed over to the other of the first network or the second network. The method also includes sending, by the information sharing network element, the monitoring information to a mobility management network element in a handed-over-to network based on a determination that the handed-over-to network supports the monitoring information. The monitoring information includes data associated with the terminal in a handed-over-from network.
