Access Network Paging Parameter Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing wireless communications systems experience reduced performance due to a large quantity of signaling interactions between terminals, access network devices, and core network devices during the paging process, particularly when terminals move within different paging areas.
Innovation Solution
The proposed method involves determining paging parameters by access network devices, rather than core network devices, to reduce signaling interactions. This includes determining paging priorities based on mapping relationships between downlink data types and priorities, allowing for classified paging and efficient data transmission without core network involvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the core network device determines paging parameters and pages the terminal, then the paging process can be completed with core network involvement, but a large quantity of signaling interaction occurs between the core network device and access network device, reducing system performance
Solution Approach 1:
The patent extracts the paging parameter determination function from the core network device and assigns it to the access network device. The access network device independently determines paging parameters including paging priority based on downlink data types, eliminating the need for signaling interactions with the core network device during paging parameter determination, thereby reducing overall signaling quantity while maintaining paging completeness
Solution Approach 2:
The access network device performs self-service by autonomously determining paging parameters and executing the paging process without requiring core network device intervention. The access network device uses pre-configured mapping relationships between downlink data types and paging priorities to make independent paging decisions, reducing signaling overhead while ensuring reliable paging delivery
2Stability of the object's composition
If the core network device determines paging parameters, then centralized control is maintained, but waiting time for core network device to send downlink data increases, reducing productivity
Solution Approach 1:
The access network device performs preliminary action by pre-determining paging parameters including paging priority based on downlink data types before actual paging execution. This preliminary determination eliminates waiting time for core network device instructions, enabling immediate paging and data transmission, thereby improving productivity while maintaining stable network control through pre-configured mapping relationships
Solution Approach 2:
The patent introduces dynamic paging priority determination at the access network device based on real-time downlink data types. The access network device dynamically adjusts paging parameters according to data urgency and type using pre-configured mapping relationships, enabling faster response times and improved data delivery speed while maintaining overall network control stability

AI summary
Embodiments of the present application provide a paging method, applied to a wireless communications system. When downlink data to a terminal reaches a first access network device from a core network, the first access network device is triggered to determine a paging parameter of the terminal, and to send, based on the paging parameter, a paging message to the terminal through the first access network device or a second access network device.
