Group Paging Mapping Management for Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, group paging methods face challenges in efficiently managing the mapping relationship between paging groups and resources, leading to potential paging failures when the number of allocated paging groups exceeds the supported resources.
Innovation Solution
The method involves a base station sending mapping relationship information to terminals, indicating the mapping between paging group information and resources. This information allows terminals to determine the appropriate paging group resource for monitoring, thereby reducing paging failures and improving reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the number of allocated paging groups exceeds the number of supported paging group resources, then the coverage of paging groups is improved, but the reliability of group paging deteriorates due to paging failures
Solution Approach 1:
The patent segments the mapping relationship information into two parts: a first part indicating the mapping relationship between paging group information and paging group resources, and a second part indicating the number of supported paging group resources. This segmentation allows terminals to separately process the mapping rules and resource capacity information, enabling accurate determination of paging group resources even when the number of allocated groups exceeds supported resources, thus preventing paging failures while maintaining extended coverage.
2Ease of operation
If mapping relationship information is not provided to terminals, then the base station maintains simpler operation, but terminals cannot correctly determine paging group resources leading to paging failures
Solution Approach 1:
The patent introduces mapping relationship information as an intermediary that bridges the base station and terminals. This information acts as a mediator that carries the mapping rules from the base station to terminals, enabling terminals to independently determine their paging group resources without complex base station intervention during the paging process, thus maintaining base station operational simplicity while ensuring reliable paging message reception.
3Device complexity
If the base station supports a limited number of paging group resources, then the system complexity is reduced, but the ability to page all terminals in allocated groups is compromised
Solution Approach 1:
The patent applies preliminary action by having the base station pre-configure and broadcast the mapping relationship information and the number of supported paging group resources before the actual paging process. This allows terminals to pre-determine their paging group resources based on the provided mapping rules and resource capacity information, enabling the system to handle more paging groups than physically supported by utilizing the mapping relationship to allocate resources efficiently, thus maintaining low system complexity while expanding paging capability.

AI summary
A method for group paging, performed by a base station, includes: sending mapping relationship information to a terminal. The mapping relationship information indicates a mapping relationship between information of a paging group and a paging group resource. The base station may determine whether to send the mapping relationship information to the terminal according to a number of paging groups allocated in a predetermined manner and a number of paging groups supported by the base station for the predetermined manner, wherein the predetermined manner is a manner that a network allocates paging groups.
