Asynchronous Event Reporting in Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication networks experience a high overhead of signaling messages and parameters across EPC interfaces, leading to inefficient event reporting processes.
Innovation Solution
Implementing an asynchronous activation or de-activation mechanism for event reporting functions in wireless communication networks, where context information is shared among network nodes to determine and manage event reporting without synchronous message propagation, reducing unnecessary signaling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If synchronous message propagation is used for event reporting activation, then event reporting accuracy is maintained, but signaling overhead increases
Solution Approach 1:
The patent extracts the event reporting activation indication from the synchronous signaling path and stores it separately in context information within the database node. This allows the MME to retrieve pre-configured event reporting parameters without requiring real-time synchronous message exchange, thereby reducing signaling overhead while maintaining reporting accuracy through the stored context information.
Solution Approach 2:
The patent implements preliminary action by pre-configuring event reporting context information in the database node before actual event reporting is needed. The SGW or PGW node stores activation indications and associated context information in advance, allowing the MME to quickly retrieve and apply these parameters without requiring synchronous coordination at the moment of event triggering, thus reducing real-time signaling overhead.
2Quantity of substance
If asynchronous activation mechanism is implemented, then signaling overhead is reduced, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary mechanism by utilizing the existing database node (SGW/PGW) as a mediator that stores context information. Instead of implementing complex asynchronous protocols between all network nodes, the system uses the database node as an intermediary repository that simplifies the asynchronous activation process. The MME retrieves pre-stored context information from this intermediary, avoiding the need for complex real-time coordination while managing system complexity through a centralized storage approach.
3Productivity
If context information is shared externally, then event reporting efficiency is improved, but information security requirements increase
Solution Approach 1:
The patent applies segmentation by dividing context information into specific components (event reporting activation indications, UE identifiers, etc.) and storing them in a structured format in the database node. This segmentation allows selective sharing of only the necessary information components for event reporting while maintaining security controls. The MME retrieves only the specific context information needed for event reporting, rather than accessing all UE data, thus improving efficiency while managing security through selective information exposure.

AI summary
A method performed by a first network node operating in a wireless communication network for enabling events triggered by a wireless device served by the first network node to be reported in the wireless communications network is provided. The first network node determines that an event has been triggered by the wireless device. Then, the first network node context information associated with the wireless device from a database node that is shared externally by the first network node with one or more network nodes in the wireless communications network, which context information indicates that events triggered in the first network node by the wireless device is to be reported in the wireless communications network. After the obtaining, the first network node determines that events triggered by the wireless device is to be reported in the wireless communications network based on the obtained context information.
