On-Demand Paging Class Segmentation for 5G Resource Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G wireless communication systems face challenges in 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 transmitting configuration information to user equipment, adjusting paging resources and intervals based on device capabilities and service levels, and temporarily suspending or modifying paging to optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If conventional paging policies are used for all user equipment, then paging coverage is maintained, but resource utilization is 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 device capabilities. This segmentation allows the network to apply different paging policies to different classes, optimizing resource utilization by not applying uniform paging to all devices. The segmentation resolves the contradiction by enabling selective paging that improves efficiency while maintaining necessary coverage for critical services.
Solution Approach 2:
The patent implements dynamic paging modification where the network node can adjust paging parameters (such as paging occasion frequency, timing, and resource allocation) based on determined paging modification parameter metrics. This dynamic adjustment allows the system to adapt paging intensity to actual network conditions and device needs, improving resource utilization during low-traffic periods while ensuring adequate coverage when needed, thereby resolving the energy consumption versus productivity contradiction.
2Use of energy by stationary object
If paging is modified or suspended for certain user equipment, then energy consumption is reduced, but paging reliability may be compromised
Solution Approach 1:
The patent applies local quality by implementing paging modification selectively for specific user equipment in the second paging class while maintaining conventional paging for the first paging class. The network node determines which devices receive modified paging based on their service requirements, capabilities, and current network conditions. This localized application of paging modification ensures that energy reduction is achieved for non-critical devices without compromising the reliability of paging for devices that require high reliability service.
Solution Approach 2:
The patent changes paging parameters dynamically based on determined metrics, adjusting the paging modification parameter to balance energy consumption and reliability. The network node monitors conditions and modifies paging parameters (such as reducing paging occasion frequency or adjusting timing) for specific devices when appropriate, while maintaining original parameters for devices requiring high reliability. This parameter adaptation resolves the contradiction by allowing flexible adjustment of paging intensity to match actual needs.
3Reliability
If paging resources are increased to maintain coverage, then paging reliability is improved, but resource utilization efficiency decreases
Solution Approach 1:
The patent applies partial action by providing enhanced paging resources and modified paging policies only to the extent necessary for specific user equipment in the second paging class, rather than uniformly to all devices. The network node determines the appropriate level of paging modification parameter adjustments based on actual needs, avoiding excessive resource allocation. This partial application of enhanced paging resources improves reliability for critical devices while maintaining efficient resource utilization overall, resolving the contradiction between reliability and productivity.

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.
