Paging Cycle Configuration for Wireless Network Collision Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in LTE and NR technologies, face challenges in managing paging cycles, leading to collisions and inefficiencies due to the inability to concurrently receive paging from multiple access links, resulting in dropped pages and increased network resource utilization.
Innovation Solution
Implementing a method where user equipment (UE) and base stations (BS) can configure and switch between multiple paging cycles based on system time, frame number, slot index, UE identity, and randomization information, allowing for pseudo-randomization of paging cycles to avoid collisions and reduce network resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single paging cycle is used for all user equipment, then the system is simple to manage, but paging collisions occur frequently and network resource utilization increases
Solution Approach 1:
The patent segments the single paging cycle into multiple paging cycles with different periodicities. Each UE is assigned to one of multiple paging cycles based on its identity and service requirements, dividing the monolithic paging structure into smaller, manageable segments that reduce collisions and improve reliability.
2Reliability
If multiple paging cycles are configured for different UEs, then paging collisions are reduced and delivery reliability improves, but the system complexity and reconfiguration overhead increase
Solution Approach 1:
The patent implements self-service by enabling UEs to autonomously determine their assigned paging cycle based on pre-configured parameters such as UE identity, service type, and QoS requirements. The UE independently selects the appropriate paging cycle without requiring network reconfiguration messages, eliminating the need for complex centralized management while maintaining high reliability.
3Productivity
If paging cycles are frequently reconfigured to optimize performance, then paging efficiency improves, but network resource utilization and signaling overhead increase
Solution Approach 1:
The patent applies preliminary action by pre-configuring multiple paging cycles with different periodicities and characteristics before UE connection. The network establishes a pool of paging cycle options during initial setup, and UEs select from this pre-prepared set based on their current service requirements, avoiding the need for frequent real-time reconfiguration and reducing signaling overhead.
Solution Approach 2:
The patent implements dynamics by enabling flexible switching between pre-configured paging cycles based on changing service requirements and QoS parameters. The system dynamically adapts to different traffic patterns and service priorities by allowing UEs to transition between paging cycles without requiring network reconfiguration, maintaining high paging efficiency while minimizing resource utilization.

AI summary
A base station (BS) may determine a first type of paging cycle configuration and a second type of paging cycle configuration that is different from the first type of paging cycle configuration, wherein the second type of paging cycle configuration enables a plurality of different paging cycles. The BS may transmit to a user equipment, a paging cycle configuration message, wherein the paging cycle configuration message allowing the terminal UE to switch among the paging cycles.
