Communication Terminal Network Joining via Connected Master Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication networks conforming to the Wi-Fi Direct specification, a terminal unconnected to any network may fail to establish connections with multiple terminals, leading to missed opportunities for communication.
Innovation Solution
A method where a terminal searches for and identifies a connected master terminal within its range, using communication messages to determine and connect with it, thereby joining the existing network.

Engineering Contradiction Analysis
1Ease of operation
If a communication terminal connects to any available terminal without discrimination, then connection establishment is simplified, but the terminal may miss opportunities to join larger networks
Solution Approach 1:
The terminal receives feedback information from discovered terminals indicating whether they are connected to networks. Based on this feedback, the terminal intelligently selects unconnected terminals as connection targets, avoiding terminals that are already part of networks. This feedback mechanism enables the terminal to adapt its connection strategy dynamically.
Solution Approach 2:
The terminal autonomously determines its connection strategy by evaluating the network connection status of discovered terminals. It automatically identifies and connects to unconnected terminals without requiring external guidance or manual intervention, thereby serving itself in optimizing network joining opportunities.
2Measurement precision
If a terminal searches for and selects specific connected master terminals, then network joining accuracy is improved, but the connection process becomes more complex
Solution Approach 1:
The terminal extracts and utilizes specific information from communication messages, namely the network connection status of other terminals. By extracting this key piece of information, the terminal can make informed connection decisions without needing to implement complex evaluation algorithms, thus maintaining simplicity while improving accuracy.
Solution Approach 2:
The terminal changes its connection selection parameter from random or first-available terminal selection to selective terminal selection based on network connection status. This parameter change enables more accurate network joining by targeting unconnected terminals specifically, while the selection criterion remains simple and easy to implement.

AI summary
A first communication terminal, unconnected with a communication network, searches for a second communication terminal existing around the own communication terminal. In the communication network, one of communication terminals functions as a master having a function of an access point and the rest of the communication terminals function as slaves of the master. Among the one or more second communication terminals found through the search, the first communication terminal determines a second communication terminal, in which information included in a communication message received from the second communication terminal shows that it is a connected master terminal which is a terminal connected with the communication network and functions as the master, to be a connection counterpart. Then, the first communication terminal configures a network with the determined connection counterpart.
