Paging Frame Grouping for UE-Specific Idle State Paging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing wireless communication systems, UEs in RRC idle or inactive states receive unnecessary paging messages due to uneven allocation of UEs with varying paging probabilities to the same paging occasions, leading to inefficient resource usage and increased power consumption.
Innovation Solution
A method and apparatus that group UEs of the same type based on their paging probabilities, allowing for more targeted paging by broadcasting a configuration message that indicates multiple paging frames within a cycle, each group associating UEs with similar paging characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If UEs with varying paging probabilities are allocated to the same paging occasions, then the paging configuration is simple, but unnecessary paging occurs leading to increased power consumption and inefficient resource usage
Solution Approach 1:
The patent segments UEs into different groups based on their paging probabilities (first group for high probability, second group for low probability). Each group is assigned to different paging frames within the paging cycle, allowing the system to tailor paging资源配置 to actual needs and reduce unnecessary paging for low-probability UEs, thereby reducing power consumption.
Solution Approach 2:
The patent applies different paging configurations to different UE groups locally. High-probability UEs receive more frequent paging opportunities in specific frames, while low-probability UEs are configured to monitor fewer frames, optimizing resource usage and energy consumption for each subgroup according to their specific characteristics.
2Device complexity
If UEs with varying paging probabilities are allocated to the same paging occasions, then the resource allocation is uniform, but resource usage becomes inefficient
Solution Approach 1:
The patent divides UEs into distinct groups (first group and second group) with different paging probabilities and allocates them to different paging frames. This segmentation enables differentiated resource allocation where resources are concentrated on high-probability UEs and reduced for low-probability UEs, significantly improving overall resource usage efficiency.
Solution Approach 2:
The patent changes the paging configuration parameters (paging frames, paging occasions) based on UE-specific paging probabilities. By adjusting these parameters dynamically according to UE behavior patterns, the system optimizes resource allocation efficiency without requiring complex real-time reconfiguration.
