Paging Message Scheduling for Public Warning Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing public warning systems face challenges in quickly and efficiently transmitting warning messages to terminal devices, leading to delays in user notification and potential loss avoidance.
Innovation Solution
A communication method and apparatus that allows terminal devices to directly receive paging messages from network devices, eliminating the need to read System Information Block Type 1 (SIB1) and obtain scheduling information, thereby reducing the time required to obtain public warning system messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If terminal devices read SIB1 and obtain scheduling information from SI message scheduling list, then they can receive public warning system messages, but the time required to obtain the messages increases
Solution Approach 1:
The network device pre-configures and sends indication information in the paging message that directly points to the scheduling information of the SI message containing the public warning system message. This preliminary action eliminates the need for terminal devices to read SIB1 and search through scheduling lists during the warning message reception process, significantly reducing the time required to obtain critical warning information while ensuring reliable message delivery.
2Reliability
If terminal devices follow the conventional procedure to read SIB1 and determine SI window location, then they can ensure accurate message reception, but the complexity of the reception process increases
Solution Approach 1:
The invention extracts the essential scheduling information and window location indicators directly into the paging message itself. By taking out the critical scheduling details from the complex SIB1 structure and embedding them in the paging message with direct indication information, the system maintains accurate message reception while dramatically simplifying the terminal device's reception process.
3Loss of information
If terminal devices obtain scheduling information through multiple steps including reading SIB1 and determining SI window location, then they can ensure complete information acquisition, but the number of steps increases transmission time
Solution Approach 1:
The invention merges the scheduling information indication directly into the paging message structure. By combining the public warning system message indication with the scheduling information and SI window location indicators in a single paging message transmission, the system ensures complete information acquisition while reducing the multi-step process to a single integrated information delivery mechanism.

AI summary
Embodiments of this application provide example communication methods and apparatuses. One example method includes receiving a paging message from a network device, where the paging message includes first information, and the first information is used to indicate a resource location of a public warning system message. The public warning system message is received based on the paging message.
