Terminal Device Paging Determination Using eDRX Cycle and Subgrouping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal devices configured with Extended Discontinuous Reception (eDRX) and supporting subgrouping paging struggle to accurately determine the information of the paging to be monitored due to existing methods of defining their identity.
Innovation Solution
The identity of the terminal device is determined based on a preset cycle of eDRX and/or the maximum number of subgroupings supported by a paging occasion, allowing accurate determination of target paging information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing methods of defining terminal device identity are used, then the terminal device can operate with standard identity definition, but the terminal device configured with eDRX and supporting subgrouping paging cannot accurately determine the information of the paging to be monitored
Solution Approach 1:
The patent changes the parameters used for identity definition by introducing a new identity formulation that incorporates both eDRX cycle information and subgrouping paging information. Specifically, the terminal device identity is defined as a function of the eDRX cycle index and the subgrouping paging index, allowing accurate determination of paging information while maintaining compatibility with existing systems.
2Use of energy by moving object
If eDRX and subgrouping paging are combined, then energy consumption is reduced and battery life is prolonged, but the terminal device cannot accurately determine the information of the paging to be monitored
Solution Approach 1:
The patent segments the identity definition into two distinct components: eDRX cycle information and subgrouping paging information. By dividing the identity into these separate but coordinated elements, the system enables accurate paging determination while maintaining the energy-saving benefits of both eDRX and subgrouping paging mechanisms.
3Ease of manufacture
If existing identity definition is used, then implementation is simple, but subgrouping indexes may be unused and paging false alarms occur
Solution Approach 1:
The patent introduces a coordinated relationship between eDRX cycle index and subgrouping paging index as an intermediary mechanism. This intermediary structure ensures that all subgrouping indexes are properly utilized and mapped to appropriate paging occasions, eliminating false alarms while maintaining implementation simplicity through standardized procedures.

AI summary
A communication method, a terminal device and a network device are provided. The method includes following operations. If a terminal device is configured with extended discontinuous reception (eDRX) and supports packet paging, the terminal device determines, according to an identifier of the terminal device, information of a target paging to be monitored. The identifier of the terminal device is determined according to a preset cycle of the eDRX and/or the maximum number of subgroupings supported by one paging occasion.
