Solution Overview

Problem

Conventional wireless communication systems cannot efficiently manage communication systems across multiple frequency channels, requiring wireless communication terminals to repeatedly scan for available base stations and re-establish connections when switching frequency channels, as they lack notification of supported communication systems on other frequencies.

Innovation Solution

A wireless communication apparatus that notifies wireless communication terminals of supported communication systems on other frequency channels through a connection management table, allowing seamless switching between frequency channels by referencing the table for compatible communication systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wireless communication terminals scan for available base stations when switching frequency channels, then connection reliability is maintained, but communication efficiency deteriorates due to repeated scanning and connection setup

Engineering Contradiction:

Improveconnection reliabilityVSAvoidcommunication efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The base station performs preliminary actions by notifying terminals of supported communication systems on other frequency channels before the terminal actually switches channels. This is achieved through notification messages containing information about available communication systems on multiple frequency channels, allowing terminals to prepare for seamless channel switching without scanning.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The base station acts as an intermediary by maintaining a connection management table that stores information about terminals and their supported communication systems across multiple frequency channels. This intermediary structure enables the base station to facilitate efficient channel switching by providing terminals with pre-configured information about available communication systems on other channels.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If wireless communication terminals repeatedly establish connections when switching frequency channels, then communication reliability is ensured, but time consumption increases

Engineering Contradiction:

Improvecommunication reliabilityVSAvoidtime consumption

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The connection management table maintains continuous information about terminal capabilities across frequency channels, allowing the communication relationship to continue seamlessly during channel switching. The terminal switches channels while maintaining its communication context, avoiding interruption and time loss associated with re-establishing connections.

Inventive Principle:

Principle #20Continuity of useful action

3Device complexity

If wireless communication systems manage multiple frequency channels without notification mechanisms, then system complexity is reduced, but information availability deteriorates

Engineering Contradiction:

Improvesystem complexityVSAvoidinformation availability

Core Design Contradiction:

Device complexityVSLoss of information

Solution Approach 1:

The base station performs multiple functions: it manages multiple frequency channels, maintains the connection management table, and sends notification messages to terminals. This multi-functional approach consolidates information management capabilities in the base station, providing comprehensive information about communication systems across channels without significantly increasing overall system complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The connection management table automatically stores and updates information about terminal capabilities and supported communication systems on different frequency channels. The system self-manages this information repository, reducing the need for complex external management mechanisms while ensuring information availability for efficient channel switching.

Inventive Principle:

Principle #25Self-service

AI summary

A wireless communication apparatus which can simultaneously conduct communication on at least two frequency channels is described. The apparatus includes a communication unit which refers to a connection management table to determine a communication system which can be used by a wireless communication terminal using an identifier of the wireless communication terminal, and conducts communication with the wireless communication terminal on a second frequency channel using the communication system, when a request from the wireless communication terminal to change the first frequency channel to the second frequency channel is permitted.
