Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks struggle to effectively manage multiple wireless terminal apparatuses to satisfy the delay requirement conditions of low latency traffic.
Innovation Solution
An access point with a wireless signal processing unit and management unit manages service periods and transmission priorities for multiple wireless terminal apparatuses, adjusting configurations to prioritize low latency traffic and resolve conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If service periods are allocated to multiple wireless terminal apparatuses simultaneously, then network throughput is improved, but transmission conflicts occur causing delay requirement violations
Solution Approach 1:
The access point performs preliminary detection of service period conflicts between multiple wireless terminal apparatuses before allocating transmission opportunities. By identifying potential conflicts in advance and adjusting service period configurations proactively, the system ensures that low latency traffic requirements are met while maintaining high network throughput through efficient resource utilization.
2Reliability
If service period configuration is adjusted to resolve conflicts, then delay requirement satisfaction is improved, but system complexity increases
Solution Approach 1:
The access point autonomously detects service period conflicts and performs self-adjustment of service period configurations without requiring external intervention or complex coordination protocols. The conflict detection and resolution mechanism operates automatically based on predefined rules, ensuring delay requirements are met while keeping the management system relatively simple and efficient.

AI summary
An access point of an embodiment includes a wireless signal processing unit and a management unit. The management unit sets a first service period for providing a first traffic transmission opportunity to the first wireless terminal apparatus in a first cycle and a second service period for providing a second traffic transmission opportunity to the second wireless terminal apparatus in a second cycle. The management unit manages a first transmission priority based on a delay requirement condition of the first traffic and a second transmission priority based on a delay requirement condition of the second traffic. In a case of detecting a conflict between the first and second service periods is detected and confirming that the first transmission priority is higher than the second transmission priority, the management unit notifies the second wireless terminal apparatus of a change in a configuration related to the second service period.
