Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The proliferation of randomly generated SSIDs for access points complicates user connectivity, leading to cumbersome SSID selection and potential loss of important connection information due to storage overflow in mobile terminals.

Innovation Solution

A method is implemented in information processing apparatuses to delete SSIDs satisfying predetermined conditions, such as those including specific character strings, thereby managing and optimizing the list of stored SSIDs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the mobile terminal stores connection information (SSID) every time it is connected to an external apparatus, then the mobile terminal can be reconnected to the access point, but a large number of SSIDs are displayed on the SSID selection screen making it cumbersome for the user

Engineering Contradiction:

Improvereconnection capabilityVSAvoidSSID selection convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts and deletes SSIDs that satisfy predetermined conditions (such as randomly generated SSIDs starting with specific characters) from the stored connection information. This selective deletion removes the cluttering elements while preserving useful connection data, thereby reducing the number of SSIDs displayed on the selection screen while maintaining reconnection capability for important access points.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If the external apparatus randomly changes the SSID every connection operation, then another mobile terminal cannot be connected to the external apparatus first, but the mobile terminal stores a large number of randomly generated SSIDs causing clutter

Engineering Contradiction:

Improveconnection exclusivityVSAvoidnumber of stored SSIDs

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent changes the parameter of SSID identification by introducing a filtering criterion based on character strings. SSIDs with specific character patterns (indicating random generation) are identified and deleted, while SSIDs without these patterns are retained. This parameter-based differentiation allows the system to distinguish between useful and useless stored SSIDs.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If the mobile terminal displays all stored SSIDs on the SSID selection screen, then all connection options are available, but the user needs to find a desired SSID from a large list which is cumbersome

Engineering Contradiction:

Improveconnection optionsVSAvoidSSID selection time

Core Design Contradiction:

Adaptability or versatilityVSLoss of time

Solution Approach 1:

The patent extracts and removes SSIDs that are likely to be randomly generated and less useful for permanent connections. By deleting SSIDs matching predetermined conditions before they are displayed, the system reduces the number of options presented to the user, thereby reducing selection time while still providing access to important connection points.

Inventive Principle:

AI summary

In a method, that is executed in an information processing apparatus, of deleting an SSID (Service Set Identifier) of an access point stored in the information processing apparatus, information indicating SSIDs stored in the information processing apparatus is obtained from the information processing apparatus, and an SSID satisfying a predetermined condition is specified among the SSIDs included in the obtained information. The information processing apparatus is instructed to delete the specified SSID.
