Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing Tunneled Direct Link Setup (TDLS) standard requires periodic channel switching between a base channel and an additional peer-to-peer channel, leading to degraded transmission performance due to channel transition and low synchronicity.
Innovation Solution
A network device and method that determine if the TDLS link throughput meets a threshold, and if so, perform an auto channel selection algorithm to establish an off channel, switching to either a dual-band concurrent mode or multi-channel concurrent mode based on the number of antennas to optimize connections.

Engineering Contradiction Analysis
1Reliability
If periodic channel switching is performed to keep devices connected to the access point, then connection reliability is maintained, but transmission performance is degraded due to channel transition and low synchronicity
Solution Approach 1:
The patent applies dynamics by making the channel switching strategy adaptive rather than fixed. The system dynamically determines whether to switch channels based on real-time throughput measurements and link conditions. When TDLS link throughput meets or exceeds the threshold, the system switches to off-channel mode; when throughput falls below the threshold, it returns to base channel mode, creating a dynamic response that balances connection reliability with transmission performance
Solution Approach 2:
The patent changes the operational parameter from fixed periodic switching to threshold-based conditional switching. By monitoring TDLS link throughput as a key parameter and using it to trigger channel mode transitions, the system optimizes transmission performance while maintaining connection reliability through parameter-driven decision making
2Adaptability or versatility
If channel switching is performed to transfer data via TDLS-link, then data transfer capability is enabled, but transmission performance is degraded due to channel transition
Solution Approach 1:
The system dynamically adapts its channel usage based on real-time throughput conditions. When TDLS link throughput is sufficient (meets or exceeds threshold), the system activates off-channel mode for enhanced data transfer capability. When throughput is insufficient, it deactivates off-channel mode to maintain stable base channel operation, creating a dynamic balance between data transfer capability and transmission performance
Solution Approach 2:
The patent implements feedback by continuously monitoring TDLS link throughput and using this information to control channel switching decisions. The throughput measurement serves as feedback that triggers appropriate channel mode transitions, ensuring that data transfer capability is activated only when transmission conditions are favorable, thus minimizing performance degradation
3Productivity
If off channel is established via auto channel selection, then transmission performance is improved, but device complexity increases due to additional mode selection logic
Solution Approach 1:
The patent simplifies the complex mode selection logic by reducing it to a single key parameter: TDLS link throughput threshold comparison. Instead of complex multi-condition decision logic, the system uses straightforward threshold-based parameter evaluation to determine whether to switch between base channel mode and off-channel mode, thereby improving transmission performance while minimizing the increase in device complexity
Solution Approach 2:
The system performs self-service by automatically monitoring its own throughput performance and autonomously making channel mode decisions without external intervention. The auto channel selection algorithm and throughput threshold comparison enable the device to self-optimize its transmission parameters, improving performance while keeping the control logic contained within the device itself

AI summary
A network device includes a processor circuit and transceiver circuits. The transceiver circuits are connected to a wireless access point via a base channel based on a control of the processor circuit. The wireless access point is connected to a first device. The processor circuit determines whether a tunneled direct link setup link (TDLS) throughput of the base channel is higher than or equal to a threshold value; if the TDLS throughput is higher than or equal to the threshold value, performs an auto channel selection algorithm to determine whether to establish an off channel; and if the off channel is established, performs one of a dual-band concurrent mode and a multi-channel concurrent mode according to a number of antennas corresponding to the transceiver circuits, in order to control at least one of the transceiver circuits to be connected to the first device via the off channel.
