UE-Specific Paging Resource Selection for RRC-Inactive Wireless Networks
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in efficiently allocating paging resources for UEs in RRC_INACTIVE state, leading to increased power consumption and potential delays in system information acquisition due to inconsistent or unavailable UE-specific paging resource configurations.
Innovation Solution
Implementing adaptive and dynamic paging resource selection methods, including UE-specific paging resource configurations, where network elements negotiate and coordinate to select optimal paging resources based on UE-specific parameters such as CEL, Rmax-paging, and DRX cycles, ensuring consistent resource allocation even in RRC_INACTIVE state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If common paging resources are used for all UEs, then resource allocation is simple, but power consumption increases and system information acquisition delays occur
Solution Approach 1:
The patent segments paging resources by creating UE-specific paging resource configurations based on UE identities (IMSI, 5G-S-TMSI, or GUTI). This segmentation allows each UE to be assigned to specific paging occasions and paging frames, reducing the need for all UEs to monitor all paging resources, thereby reducing power consumption while maintaining manageable allocation complexity through systematic segmentation rules.
Solution Approach 2:
The patent applies local quality by tailoring paging resource allocation to individual UE characteristics. Each UE receives customized paging parameters including specific paging occasions, paging frames, and monitoring configurations based on its identity and service requirements. This localized optimization reduces power consumption for each UE without requiring complex network-wide resource management.
2Use of energy by moving object
If UE-specific paging resource configurations are implemented, then power consumption is reduced, but device complexity and coordination requirements increase
Solution Approach 1:
The patent implements a universal paging resource configuration mechanism that can serve multiple UEs with similar characteristics using the same configuration templates. The network elements (AMF, gNB, NG-RAN) use standardized algorithms and formulas to generate paging parameters, allowing them to handle multiple UEs efficiently without requiring complex individual coordination for each UE. This multi-functionality approach reduces network element complexity while maintaining UE-specific optimization.
Solution Approach 2:
The patent uses parameter changes by dynamically adjusting paging-related parameters (paging occasion, paging frame, monitoring timing) based on UE identities and network conditions. The standardized formulas and algorithms allow network elements to automatically adjust these parameters without complex manual coordination, reducing the perceived complexity while achieving UE-specific power optimization.
3Productivity
If standardized formulas and algorithms are used for paging resource determination, then allocation efficiency is improved, but adaptability to specific UE requirements may be limited
Solution Approach 1:
The patent applies dynamics by making paging resource configurations adaptable and changeable based on UE state transitions and network conditions. The standardized formulas incorporate dynamic elements such as UE identity variations, service type changes, and network load conditions, allowing the system to maintain high allocation efficiency through automated calculations while adapting to specific UE requirements through parameter variations.
Solution Approach 2:
The patent implements feedback mechanisms where network elements monitor UE paging reception success and adjust configurations accordingly. The standardized algorithms incorporate feedback from UE responses and network observations to refine paging resource allocation, maintaining efficiency through systematic processing while improving adaptability to specific UE requirements over time.

AI summary
This disclosure relates generally to adaptive and dynamic paging resource selection and System Information (SI) acquisition in a wireless communication network. Performed by a first network element in a network, the method including: receiving a first message from a second network element of the network; deriving a User Equipment (UE) specific paging resource configuration associated with a UE based on the first message; selecting a paging radio resource based on the UE specific paging resource configuration and based on a radio resource specific paging configuration pre-defined in the first network element; and sending a paging message over the selected paging radio resource to the UE while the UE is in a radio resource control (RRC) inactive state..
