Multi-AP Group Joining With Guard Window Synchronization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face challenges in seamlessly integrating new access points (APs) into existing multi-AP coordinated groups without disrupting ongoing operations or requiring group reformation, especially in dynamic and diverse deployment scenarios.
Innovation Solution
A method and system for managing multi-AP coordinated groups that enable new APs to discover and synchronize with existing groups by broadcasting coordination information, negotiating compatibility, and synchronizing behavior, allowing for selective integration without disrupting ongoing operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a new AP joins an existing multi-AP coordinated group, then the group's coverage and capacity are improved, but the synchronization and coordination among APs may be disrupted
Solution Approach 1:
The patent applies preliminary action by requiring the new AP to perform capability negotiation and synchronization parameter alignment with existing group members before officially joining the coordinated group. This pre-joining preparation ensures that the new AP is fully compatible with group operations, preventing disruptions to synchronization and coordination while enabling seamless integration that improves overall group coverage and capacity.
2Stability of the object's composition
If existing multi-AP coordinated groups require reformation to integrate new APs, then group integrity is maintained, but signaling overhead and operational complexity increase
Solution Approach 1:
The patent applies segmentation by dividing the AP integration process into distinct phases: capability advertisement, capability negotiation, synchronization parameter alignment, and formal group joining. This segmented approach allows new APs to integrate without triggering complete group reformation, maintaining group integrity while reducing signaling overhead and operational complexity compared to traditional reformation-based methods.
3Adaptability or versatility
If new APs are integrated into coordinated groups, then network scalability is improved, but compatibility and synchronization challenges arise
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting synchronization parameters and coordination settings based on the new AP's capabilities and current group state. During the capability negotiation phase, the system modifies timing parameters, power levels, and coordination modes to ensure compatibility. This parameter adaptation enables network scalability while managing compatibility and synchronization challenges through automated adjustment rather than manual configuration.

AI summary
The present disclosure relates to a method and an apparatus for managing a multi-access point (AP) coordinated group by at least one AP. The method comprises: broadcasting coordination information comprising a group identifier and guard window time information; receiving a join request from an external AP requesting to join the multi-AP coordinated group; determining whether the external AP is permitted to join the multi-AP coordinated group based on the guard window time information; and transmitting a response to the external AP based on the determination, wherein the response may indicate whether the join request is accepted or rejected.
