Dynamic Paging Resource Allocation in D2D Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communications, resource utilization is low due to reserved resources not being reused when devices do not communicate as expected, leading to wasted resources and inefficient spectrum use in D2D communication.
Innovation Solution
A paging method where a first terminal requests the network side device to instruct it to page a second terminal only when necessary, allowing the network side device to schedule resources effectively and reuse reserved resources if they are not used, thereby improving resource utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station reserves a resource for the occasion on which the terminals communicate with each other, then the communication between the terminals can be ensured, but the resource cannot be reused if the terminals do not communicate, leading to low resource utilization
Solution Approach 1:
The patent implements dynamic resource allocation by allowing terminals to request paging resources only when needed, rather than reserving resources statically. The base station dynamically grants or releases resources based on actual communication needs, enabling resources to be reallocated to other uses when not required, thus resolving the contradiction between ensuring communication reliability and improving resource utilization
Solution Approach 2:
The system changes the state of resource allocation from fixed/reserved to flexible/dynamic by introducing a request-response mechanism. Resources are allocated based on changing parameters such as paging needs and terminal availability, allowing the system to adapt resource usage patterns and improve overall utilization while maintaining reliability when needed
2Reliability
If the base station reserves resources for terminal communication, then communication can proceed as expected, but the reserved resources are wasted when terminals do not communicate, leading to inefficient spectrum use
Solution Approach 1:
Terminals autonomously determine when paging is needed and actively request resources from the base station. This self-service approach eliminates the need for the base station to pre-reserve resources, as terminals only consume resources when they actually need to communicate, thereby preventing spectrum waste while ensuring communication reliability when required

AI summary
Embodiments of the present invention provide a paging method and a related device. The paging method includes: sending, by a first device, a first message to a network side device; receiving, by the first device, a second message sent by the network side device; and sending, by the first device, a paging message to the second device based on the second message. It can be learned that, when the network side device determines that the first device can page the second device, the network side device sends the second message to the first device, and the first device may page the second device based on the second message. The network side device may instruct the first device to page the second device while ensuring resource utilization, so that resource utilization is effectively ensured, and a resource waste is effectively avoided.
