IAB Base Station Access Control via Dedicated Cell Barring Parameter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication technologies lack a method to effectively control access for integrated access and backhaul (IAB) base stations, which is essential for managing network complexity and flexibility as the number of mobile base stations increases.
Innovation Solution
The method involves sending and receiving indication information using system and broadcast information, including parameters such as cell barring and reservation status, to determine whether access to another IAB base station is allowable, allowing for independent control of IAB base station access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access control for IAB base stations is managed through existing UE access control mechanisms, then system compatibility is maintained, but IAB base station access cannot be independently controlled
Solution Approach 1:
The patent segments access control into two independent mechanisms: one for UE access control (existing cell barring parameters) and another for IAB base station access control (new cellBarringIAB parameter). This segmentation allows IAB base stations to be controlled independently from UEs while maintaining compatibility with existing systems.
Solution Approach 2:
The patent introduces an intermediary parameter cellBarringIAB that specifically targets IAB base station access control. This intermediary mechanism bridges the gap between existing UE access control and the need for independent IAB control, allowing differentiated access policies without overhauling the entire access control system.
2Area of stationary object
If the number of mobile base stations increases to enhance network coverage, then network coverage is improved, but network management complexity increases
Solution Approach 1:
By segmenting access control into UE-specific and IAB-base-station-specific mechanisms, the patent enables scalable network management. Each IAB base station can be independently configured and controlled through the cellBarringIAB parameter, allowing linear scaling of network coverage without exponential increase in management complexity.
3Adaptability or versatility
If existing cell barring parameters are used for both UE and IAB base station access control, then system simplicity is maintained, but differentiated access control is impossible
Solution Approach 1:
The patent applies local quality by creating a dedicated cellBarringIAB parameter specifically for IAB base station access control, while leaving existing cell barring parameters for UE access control. This localized specialization enables differentiated access policies for different device types without complicating the overall parameter structure.
