Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in improving communication reliability and throughput, particularly in scenarios where terminal devices move and require handovers between access point devices.
Innovation Solution
Implementing a multi-link operation (MLO) that allows a non-access point multi-link device to connect simultaneously to multiple access point devices, utilizing a first and second link set for data transmission and reception, with selection criteria for secondary access point devices based on signal strength and load to enhance communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal device connects to a single access point device, then the connection is simple and easy to manage, but communication reliability and throughput are limited
Solution Approach 1:
The patent combines multiple access point devices into a unified network service provision system. The terminal device establishes connections to multiple access points simultaneously, merging their services to achieve higher reliability and throughput while maintaining unified network management through the access point selection module.
Solution Approach 2:
The access point selection module provides multi-functionality by automatically selecting optimal access points based on multiple criteria (signal strength, load, distance) and managing multiple connections simultaneously. This universal selection mechanism handles various scenarios including handovers, load balancing, and failover without requiring complex manual configuration.
2Productivity
If multiple access point devices provide network services simultaneously, then communication throughput and reliability improve, but the system complexity and coordination difficulty increase
Solution Approach 1:
The system implements feedback mechanisms where access points transmit their status information (load, signal strength, available resources) to the terminal device. The access point selection module uses this feedback to dynamically select optimal access points and adjust connections, enabling automatic load balancing and resource optimization without complex centralized control.
Solution Approach 2:
The terminal device autonomously manages multiple access point connections by automatically selecting, switching between, and dropping connections based on real-time conditions. The access point selection module self-adjusts without external intervention, handling handovers and load balancing automatically to reduce system complexity.
3Stability of the object's composition
If the terminal device frequently handovers between access points, then continuous network service is maintained, but acknowledgment information conflicts may occur
Solution Approach 1:
The system performs preliminary actions by establishing multiple simultaneous connections to different access points before handover is needed. The terminal device pre-configures alternative paths and maintains background connections, so when handover is required, the new access point is already prepared and can immediately take over without disrupting ongoing communications or causing acknowledgment conflicts.
Solution Approach 2:
The patent provides beforehand cushioning by maintaining redundant connections to multiple access points simultaneously. This redundancy acts as a buffer during handover transitions, ensuring that if one access point experiences issues or requires switching, the terminal can seamlessly switch to another connection without losing acknowledgment information or experiencing service interruption.

AI summary
This application provides a communication method, a communication apparatus, and a communication system. According to this method, a manner of cooperative communication between a plurality of access point devices is constructed. To be specific, one non-access point multi-link device may be connected to two or more access point devices (for example, connected to two access point multi-link devices, or connected to one access point multi-link device and one access point device) simultaneously. Therefore, the plurality of access point devices may provide, in same time, network services for the non-access point multi-link device simultaneously, so that communication reliability and a communication throughput can be improved.
