Solution Overview

Problem

Existing Wi-Fi network connection algorithms fail to optimize overall system performance in scenarios with multiple concurrent networks, leading to reduced throughput and increased latency due to improper channel selection and frequent switching.

Innovation Solution

A channel management method and system that employs an enhancement channel selection algorithm to determine the second channel for a new network connection, considering the existence of the first channel, thereby prioritizing Single Channel Contention (SCC) or Dual-Band Dual-Concurrent (DBDC) scenarios to reduce channel switching and interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If regular channel selection algorithm is used for each network independently, then each network can establish connections based on individual criteria (RSSI, interference, bandwidth), but multiple concurrent networks operate on different channels causing channel switching overhead and reduced overall throughput

Engineering Contradiction:
Improvenetwork connection flexibilityVSAvoidoverall system throughput
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The enhancement channel selection algorithm performs preliminary assessment of channel availability and device concurrency status before establishing new network connections. By evaluating which channels are already in use and predicting potential MCC scenarios in advance, the system pre-selects optimal channel configurations that prevent channel switching overhead, thereby maintaining connection flexibility while avoiding throughput degradation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The algorithm continuously monitors the operational status of concurrent networks and channel usage patterns, using this feedback to dynamically adjust channel selection decisions. When detecting that multiple networks are operating concurrently, the system receives feedback about the current channel configuration and modifies subsequent channel selections to consolidate networks onto fewer channels, thus improving overall throughput while preserving individual network adaptability.

Inventive Principle:
Principle #23Feedback

2Ease of operation

If devices establish connections on different channels for multiple concurrent networks, then individual network preferences are satisfied, but channel switching occurs leading to increased latency

Engineering Contradiction:
Improveindividual network connection easeVSAvoidchannel switching latency
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The enhancement channel selection algorithm merges multiple network connections onto the same channel or coordinated channels when concurrency is detected. By consolidating P2P and STA networks onto a shared channel configuration, the system eliminates the need for frequent channel switching between networks, thereby reducing latency while still allowing each network type to establish connections according to its operational requirements.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The channel selection becomes dynamic rather than static, adapting to the concurrent operation status of multiple networks. The algorithm continuously adjusts channel assignments based on real-time detection of MCC scenarios, transitioning from independent channel selection for each network to a coordinated dynamic selection process that minimizes channel switching events and associated latency.

Inventive Principle:
Principle #15Dynamics

3Reliability

If independent channel selection is performed for each network type (P2P, STA), then specific network requirements are met, but overall system performance is suboptimal due to MCC scenarios

Engineering Contradiction:
Improvenetwork connection reliabilityVSAvoidsystem performance
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The enhancement channel selection algorithm serves multiple network types (P2P, STA, and their concurrent combinations) with a single unified decision-making framework. This universal algorithm evaluates channel requirements across all network types simultaneously and produces coordinated channel assignments that satisfy individual network reliability requirements while optimizing overall system performance, eliminating the need for separate independent selection processes.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The enhancement channel selection algorithm acts as an intermediary layer between individual network connection requests and the physical channel allocation. It mediates between the competing requirements of multiple networks by translating individual connection needs into coordinated channel assignments, ensuring that each network maintains reliable connectivity while the overall system achieves optimal performance through reduced MCC scenarios.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A channel management method for concurrent networks, performed by a wireless device includes establishing a first connection in a first network with a first communication device through a first channel, and establishing a second connection in a second network with a second communication device through a second channel. The second network is the same as or different from the first network. The second channel is determined by an enhancement channel selection algorithm that takes into account the existence of the first channel through which the first connection has been established.
