Base Station Paging Optimization via Segmented Occasions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 5G systems waste paging resources due to the need to configure resources for all paging occasions, even when system message changes occur infrequently, especially for devices with shorter paging occasion intervals compared to system message change cycles.
Innovation Solution
Implementing multiple paging types with corresponding paging occasion parameters allows the base station to selectively transmit paging messages at specific occasions, optimizing resource usage by matching message types with appropriate occasions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If paging resources are configured for all paging occasions to ensure system message change notification, then reliability of notification is improved, but paging resource waste increases
Solution Approach 1:
The patent segments paging occasions into two distinct types: first paging occasions for system message change notifications and second paging occasions for downlink data notifications. This segmentation allows the base station to selectively transmit different paging message types at appropriate occasions, avoiding the waste of transmitting system message change notifications at all paging occasions when such changes do not occur frequently.
Solution Approach 2:
The patent applies local quality by assigning different functions to different paging occasions based on local conditions. First paging occasions are specifically designated for system message change notifications, while second paging occasions are used for downlink data notifications. This localized functional assignment optimizes resource usage by matching notification types with appropriate transmission opportunities rather than using a uniform approach across all occasions.
2Speed
If paging occasions are configured with short intervals to improve notification timeliness, then notification speed is improved, but resource consumption increases
Solution Approach 1:
The patent implements periodic action by establishing regular intervals between first paging occasions that align with system message change cycles. This periodic configuration ensures timely notification when system messages change while avoiding unnecessary transmissions during intervals when no changes occur, thereby balancing notification speed with resource conservation.
Solution Approach 2:
The patent applies dynamics by making the paging occasion configuration adaptive to actual system message change frequencies. The base station can adjust the interval and frequency of first paging occasions based on observed system message change patterns, optimizing the balance between notification timeliness and resource consumption rather than using fixed intervals regardless of actual needs.

AI summary
Provided are a paging optimization method and apparatus. The method includes: determining, by a base station, paging types and corresponding paging occasion parameters, where the paging types comprise at least two types; and when transmitting a paging message by the base station, selecting a corresponding paging type and transmitting the paging message at a paging occasion corresponding to the paging type by the base station. Through adopting multiple paging types, different paging messages may correspond to different paging types and different paging occasions, so that the paging resources are effectively saved.
