Wireless Terminal Network Selection via SSID Pattern Filtering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, especially in ad hoc networks, the large number of Basic Service Sets (BSSs) in a neighborhood leads to inefficient terminal participation due to the need for extensive memory storage and prolonged scanning times when searching for specific networks without known SSIDs, as terminals must list all BSSs, resulting in a cumbersome and resource-intensive process.
Innovation Solution
A wireless communication terminal employs a method to acquire and list network identifiers with predetermined patterns, allowing it to selectively participate in wireless networks by filtering and reducing the list of potential networks through pattern matching, thereby optimizing memory usage and scanning efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a terminal lists all BSSs in the neighborhood to allow user selection, then the terminal can find the desired network, but the memory capacity required increases and the scanning time increases
Solution Approach 1:
The patent extracts only the necessary portion of network information by filtering BSSs based on predetermined patterns (such as SSID patterns) rather than storing all BSS information. This selective extraction reduces memory requirements while maintaining the ability to find desired networks.
Solution Approach 2:
The patent applies different filtering criteria to different search scenarios. By using predetermined patterns to selectively identify relevant BSSs, the system adapts the search scope to local conditions, storing only the necessary network information rather than uniformly storing all BSS data.

AI summary
A game device is provided with a processor and an air interface apparatus. In a wireless communication environment such as that of IEEE802.11, a CPU of the air interface apparatus selects, in a search process, an SSID that includes at least in a portion thereof a predetermined pattern. Network information including the selected SSID is retained in a memory unit as a BSS list registering wireless networks that are targets, for connection. The processor refers to the BSS list and determines a wireless network to participate in.
