Paging Grant Short Message Notification Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication technologies, such as LTE and NR, face delays and resource inefficiencies in transmitting public warning system notifications and system information updates due to the need for UEs to acquire and read separate paging messages and system information blocks, which can be time-consuming, especially for urgent messages.
Innovation Solution
A method and apparatus for wireless communication that includes receiving a paging grant with a short paging message and a notification of its trigger reason, allowing UEs to determine the presence of the short message and obtain the reason without needing to search for separate paging messages or system information blocks, thereby reducing delays and conserving resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If separate paging messages and system information blocks are used to transmit notifications, then the system can provide comprehensive information, but the time delay increases and resource efficiency decreases
Solution Approach 1:
The patent combines the paging message and system information block into a single integrated structure. The paging grant includes both the paging message and the system information block that would traditionally be transmitted separately, allowing UEs to receive notifications and system information updates simultaneously without requiring separate acquisition and reading processes.
Solution Approach 2:
The paging grant is designed to serve multiple functions simultaneously: it conveys paging information, includes system information updates, and provides notification reasons all in one message. This multi-functional design eliminates the need for separate message types and reduces the overall time and resources required for communication.
2Loss of time
If UEs acquire and read separate paging messages and system information blocks, then complete information is obtained, but processing time and resource consumption increase
Solution Approach 1:
The patent merges the acquisition of paging messages and system information blocks into a single operation. The UE receives both the paging message and the system information block together in the paging grant, eliminating the need for separate acquisition steps and reducing processing time and energy consumption.
Solution Approach 2:
The system information block is prepared and included in advance within the paging grant structure. This preliminary inclusion of system information allows the UE to process both paging and system information updates in a single operation, rather than requiring subsequent separate acquisition and processing steps.
3Speed
If traditional paging mechanisms are used with separate messages, then system flexibility is maintained, but notification delivery speed decreases for urgent messages
Solution Approach 1:
The patent combines urgent notification delivery with system information updates in a single integrated paging grant structure. This allows urgent notifications to be delivered at high speed while maintaining the necessary system flexibility through the standardized integrated format, without requiring complex separate message handling procedures.

AI summary
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a paging grant that includes a short paging message and a notification of a reason that the short paging message was triggered; determine that the paging grant includes the short paging message; and obtain the notification of the reason that the short paging message was triggered based at least in part on determining that the paging grant includes the short paging message. Numerous other aspects are provided.
