Paging Mode Switching for Lower Overhead Wireless Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in managing paging resources, leading to excessive network overhead, increased power consumption, and decreased throughput due to static paging mode configurations that do not adapt to changing network conditions.
Innovation Solution
Implementing dynamic paging mode adaptation by allowing user equipment (UE) to switch between different paging modes based on signaling indicating a change, adapting configurations based on parameters like paging rate and blocking rate, and using unique P-RNTIs to reduce unnecessary decoding attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If static paging mode configuration is used, then device complexity is reduced and ease of operation is improved, but network overhead increases and throughput decreases
Solution Approach 1:
The patent implements dynamic paging mode adaptation where the network can switch between first mode (traditional paging) and second mode (group-based paging) based on current network conditions. The network determines when to activate each mode and signals UEs accordingly, allowing the system to adapt to varying traffic demands and optimize throughput while maintaining operational simplicity through automated mode selection.
2Device complexity
If static paging mode configuration is used, then device complexity is reduced, but network overhead increases and power consumption increases
Solution Approach 1:
The dynamic mode adaptation allows the network to switch to group-based paging mode when appropriate, enabling UEs to monitor group-specific P-RNTIs and reduce unnecessary decoding attempts. This reduces power consumption by allowing UEs to efficiently determine whether paging messages are intended for them, while the automated signaling keeps UE complexity low.
3Productivity
If dynamic paging mode adaptation is implemented, then throughput is improved and power consumption is reduced, but device complexity increases
Solution Approach 1:
The network autonomously determines the appropriate paging mode based on current conditions and signals UEs to switch modes accordingly. This self-service approach allows dynamic optimization of throughput and power efficiency while minimizing UE complexity, as the network handles the complexity of mode selection and switching rather than requiring complex UE-side decision-making.
4Adaptability or versatility
If traditional paging mode is used, then compatibility is maintained, but network overhead increases
Solution Approach 1:
The patent segments paging into two distinct modes: traditional individual paging for compatibility and group-based paging for efficiency. By dividing the paging functionality into separate modes with different characteristics, the system can maintain backward compatibility through the first mode while reducing network overhead by activating the second mode when appropriate, avoiding the need to choose one approach exclusively.
