System Information Processing in Dual-Connectivity 5G Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G communication systems, the existing methods for handling System Information (SI) changes in dual-connectivity scenarios are complex and inefficient, leading to increased load and complexity for User Equipment (UE) due to the need for frequent handovers and independent monitoring of SI from multiple base stations.
Innovation Solution
A method and apparatus for processing SI changes in a dual-connectivity-based mobile communication system, where a User Equipment (UE) receives change notifications from a first base station and waits for updated SI, and the base stations broadcast change indication information, reducing unnecessary monitoring and overhead by using predefined patterns and indicators within paging messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing methods for handling SI changes in dual-connectivity scenarios are used, then complete SI update information can be provided, but the complexity and load on UE increases due to frequent handovers and independent monitoring from multiple base stations
Solution Approach 1:
The patent combines SI change notifications from multiple base stations into a single unified notification mechanism. The serving base station aggregates SI change information from neighbor base stations and delivers it to the UE through one point of contact, eliminating the need for the UE to independently monitor multiple base stations and reducing handover frequency while maintaining complete SI update information.
2Loss of information
If existing methods for handling SI changes in dual-connectivity scenarios are used, then SI information can be transmitted, but the overhead and load on base stations increases
Solution Approach 1:
The serving base station acts as an intermediary between neighbor base stations and the UE. It receives SI change notifications from neighbor base stations, processes and consolidates this information, and then transmits the unified notification to the UE. This intermediary role reduces the total communication overhead by eliminating redundant transmissions and consolidating information flow through a single base station.
