Communication Device TDLS Connection Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly those using the IEEE802.11 standard, do not adequately consider the impact of establishing direct connections via Tunneled Direct Link Setup (TDLS) on existing connections, leading to potential instability and complexity in managing multiple connections.
Innovation Solution
A communication device is equipped with a control unit that restricts the establishment or switching of direct connections based on its current connection state, preventing excessive connection establishment and maintaining communication stability by determining whether to respond to or refuse TDLS requests and channel switching requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless communication device establishes multiple direct connections via TDLS simultaneously, then communication versatility and connectivity options are improved, but connection management complexity and system stability deteriorate
Solution Approach 1:
The patent applies preliminary action by checking whether a direct connection is already established before allowing a new TDLS connection to be formed. The control unit determines the connection state in advance and uses this information to decide whether to permit the new connection request, thereby preventing excessive connection complexity while maintaining versatility when appropriate
2Adaptability or versatility
If channel switching is allowed for direct connections, then communication flexibility is improved, but network stability and interference with existing connections deteriorates
Solution Approach 1:
The patent applies preliminary anti-action by detecting whether a direct connection already exists before allowing channel switching operations. When a direct connection is detected, the control unit prevents channel switching requests from being executed, thereby counteracting the potential harmful effect of interfering with existing connections while still allowing flexibility when no conflicting connections are present

AI summary
A communication device has a first function for forming a network, a second function for joining a network formed by a first other communication device, and a third function for communicating with a second other communication device that has joined the network formed by the first other communication device, through a direct connection based on the network formed by the first other communication device, when the communication device has joined, using the second function, the network formed by the first other communication device, and controls the third function so as to restrict processing for the direct connection using the third function, when the network has been formed by the first function.
