Proximity Indication Reporting Control in Small Cell Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex small cell network environments, existing methods for Proximity Indication (PI) reporting are inefficient, leading to excessive information reporting and resource waste on the air interface, particularly in densely deployed small cell scenarios, which hampers accurate handover judgments and network performance.
Innovation Solution
A method and system where User Equipment (UE) receives PI information requests from the network side, allowing for controlled reporting of PI information, reducing unnecessary reporting by using specified RAT/frequency point, cell type, and geographical position information, enabling more accurate and effective PI information reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If UE autonomously triggers PI reporting based on stored historical information of small cells, then handover timing is improved, but excessive PI information is reported causing air interface resource waste
Solution Approach 1:
The network side pre-configures PI reporting control indication information and measurement control commands in RRC connection reconfiguration messages before handover scenarios occur. This preliminary configuration enables the UE to report PI information only when specific conditions are met, avoiding unnecessary reporting and reducing air interface resource waste while ensuring timely handover.
Solution Approach 2:
The network side receives PI information from UE and provides feedback by transmitting measurement control commands based on the reported PI data. This feedback mechanism allows the network to control and optimize PI reporting dynamically, reducing excessive reporting while maintaining accurate handover judgment.
2Device complexity
If network side uses simple PI reporting control indication, then system complexity is reduced, but PI information reporting accuracy deteriorates in dense small cell scenarios
Solution Approach 1:
The PI reporting control mechanism is segmented into multiple components: PI reporting control indication information for basic control, measurement control commands for detailed measurement configuration, and PI information requests for specific data retrieval. This segmentation allows the network to achieve precise control over PI reporting accuracy in dense small cell scenarios while maintaining manageable system complexity through modular control elements.
