Access Point Service Synchronization via Trigger Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi technologies face network congestion and stalling due to independent channel contention by multiple access points, leading to inefficient service transmission.
Innovation Solution
Implementing a service transmission method where a first access point sends a radio frame to a second access point to synchronize service initiation, allowing both access points to orderly initiate services and reduce network congestion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple access points operate independently and contend for channels independently, then each access point can autonomously manage its own transmission, but network congestion and stalling are aggravated
Solution Approach 1:
The patent merges the independent operations of multiple access points by introducing a coordinator access point that sends trigger frames to coordinate service initiation among multiple access points. This combines their operations into a synchronized sequence, preventing simultaneous channel contention and reducing network congestion while maintaining autonomous operation benefits.
Solution Approach 2:
The coordinator access point performs preliminary action by sending trigger frames before the actual service transmission begins. These trigger frames carry timing information and service identifiers that prepare subsequent access points for synchronized operation, ensuring they initiate services at appropriate times without causing congestion.
2Productivity
If access points send services simultaneously without coordination, then service transmission can proceed in parallel, but channel congestion increases leading to stalling
Solution Approach 1:
The patent implements periodic action through synchronized service initiation where access points transmit services in coordinated time periods rather than continuously. The trigger frames establish periodic transmission schedules with specific timing information, creating rhythm in the channel usage pattern that prevents random simultaneous transmissions and reduces congestion.
Solution Approach 2:
The system uses feedback mechanisms where the coordinator access point sends trigger frames containing timing information and service identifiers to other access points. This feedback loop allows access points to adjust their transmission timing based on coordinated information, preventing collisions and reducing channel congestion while maintaining high throughput.

AI summary
This application provides a service transmission method and a communication apparatus. The method includes: A first access point sends a radio frame to a second access point, where the radio frame indicates a service synchronously transmitted by the first access point and the second access point; and the first access point initiates the service. According to the foregoing technical solution, in this application, service synchronization between the first access point and the second access point can be implemented. Correspondingly, the first access point and the second access point may orderly initiate the service, so that network congestion and stalling can be alleviated.
