Paging Group Mapping for UE Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing communication technologies, when paging is performed without grouping, User Equipments (UEs) with relatively low paging probabilities may be incorrectly awakened, leading to unnecessary power consumption.
Innovation Solution
The method involves a base station sending first information to determine the supported paging grouping mode and the mapping relation between paging groups and resources, allowing UEs to accurately identify their paging grouping resources.

Engineering Contradiction Analysis
1Reliability
If paging is performed without grouping, then all UEs at a Paging Occasion are woken up, but UEs with relatively low paging probabilities may be awakened incorrectly causing unnecessary power consumption
Solution Approach 1:
The patent divides UEs into multiple paging groups based on their paging probabilities and assigns different paging occasions to each group. This segmentation allows the network to page UEs more efficiently by targeting specific groups rather than waking up all UEs simultaneously, thereby reducing unnecessary power consumption while maintaining reliable paging message delivery.
Solution Approach 2:
The patent applies different paging strategies to different UE groups based on their local characteristics (paging probabilities). High probability UEs are assigned to different paging occasions than low probability UEs, allowing each group to be paged according to its specific needs and reducing overall power consumption.
2Use of energy by moving object
If paging grouping is implemented, then power consumption is reduced, but the system complexity increases due to need for grouping configuration and mapping
Solution Approach 1:
The patent performs preliminary grouping of UEs into different paging groups and assigns paging occasions before actual paging occurs. The network configures the mapping between paging groups and paging occasions in advance, so that during paging operation, the network simply needs to reference the pre-established mapping rather than performing complex real-time calculations.
Solution Approach 2:
The patent introduces a paging group mapping relationship as an intermediary structure that simplifies the paging process. Instead of directly managing complex grouping configurations, the network uses this mapping table to translate paging group identifiers to corresponding paging occasions, reducing operational complexity.
