5G Paging Class Adaptation for Resource and Energy Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G wireless communication systems face challenges in efficiently managing varying resource demands and load imbalances due to different quality-of-service classes, particularly in mobile devices, leading to inefficient resource utilization and increased energy consumption.
Innovation Solution
A radio network node determines a paging modification parameter metric and implements a modified paging policy by configuring user equipment with specific paging class indications, adjusting paging resources, and temporarily suspending or modifying paging processes based on criteria such as resource utilization and energy consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional paging policies are used for all user equipment, then uniform service coverage is maintained, but resource utilization becomes inefficient and energy consumption increases
Solution Approach 1:
The patent segments user equipment into different paging classes (first paging class and second paging class) based on service requirements and QoS parameters. This segmentation allows the network to apply differentiated paging policies - such as different paging occasions, paging cycles, and resource allocation - to different classes, thereby improving resource utilization efficiency and reducing unnecessary energy consumption from uniform paging approaches.
Solution Approach 2:
The patent implements dynamic paging policy adaptation where the network can modify paging parameters (such as paging cycles, occasions, and resource allocation) based on current network conditions, user equipment mobility patterns, and QoS requirements. This dynamic adjustment enables the system to optimize resource utilization in real-time while reducing energy consumption during low-activity periods.
2Reliability
If frequent paging is implemented to ensure service availability, then service reliability improves, but false paging rates increase and network efficiency decreases
Solution Approach 1:
The patent applies different paging characteristics to different paging classes based on their specific service requirements. High-reliability services receive more frequent paging with shorter cycles, while low-priority services use extended paging cycles. This localized quality approach ensures that each service class receives appropriate paging frequency to maintain its required availability without causing false paging in other classes, thereby preserving network efficiency.
Solution Approach 2:
The patent changes key paging parameters (paging cycle length, number of paging occasions, resource allocation) based on the paging class and current network conditions. By dynamically adjusting these parameters, the system maintains high service availability for critical services while reducing paging frequency for non-critical services, thus minimizing false paging rates and improving overall network efficiency.
3Adaptability or versatility
If paging resources are allocated uniformly to all user equipment, then service fairness is maintained, but load imbalances occur and resource demands cannot be met
Solution Approach 1:
The patent segments user equipment into different paging classes based on QoS parameters, service types, and mobility patterns. This segmentation enables the network to allocate paging resources according to specific service requirements rather than uniformly, allowing high-priority services to receive adequate resources during peak demand while low-priority services use resources during off-peak times, thus adapting to varying resource demands.
Solution Approach 2:
The patent creates a universal paging framework that can accommodate multiple service classes with different requirements through a common set of paging mechanisms. The differentiated paging classes share the same physical resources but with different allocation rules, timing, and priorities, enabling the system to handle diverse service demands without requiring separate dedicated resources for each service type.

AI summary
A serving radio network node may configure a user equipment with one or more paging class indications associated with one or more paging classes that may correspond to one or more capabilities corresponding to the user equipment. If the serving node determines to implement a paging modification policy based on a paging modification metric satisfying a paging modification criterion, the serving node may transmit to the user equipment an indication indicative that the serving node is temporarily suspending paging with respect to one or more of the paging classes. The user equipment may monitor a paging occasion corresponding to a node neighboring the serving node. If the user equipment detects, during a paging occasion corresponding to the neighboring node, a paging message corresponding to a suspended paging class, the user equipment may establish a connection with either the serving node or the neighboring node based on a configured indication.
