Solution Overview

Problem

Existing wireless communication devices store connection IDs of previously connected mobile communication terminals in memory, leading to a memory load that is not efficiently managed.

Innovation Solution

A communication device that obtains and stores variable communication information and identification information for establishing wireless connections, and upon disconnection, deletes the old information while associating new information with the updated identification, thereby reducing memory load.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If connection IDs of previously connected terminals are stored in memory, then connection history can be maintained and future connections can be facilitated, but memory load increases and memory resources are consumed

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The patent applies the discarding and recovering principle by deleting old connection information from memory after it has served its purpose of facilitating reconnection. The system maintains connection history only as long as needed, then discards it to free up memory resources, thereby resolving the contradiction between maintaining connection history and reducing memory load.

Inventive Principle:

Principle #34Discarding and recovering

Solution Approach 2:

The patent implements a dynamic memory management approach where the connection history is not statically stored but dynamically updated - adding new connection information when connections are established and deleting old information when memory capacity is reached or after a certain period. This dynamic approach allows the system to adapt memory usage to actual needs, balancing connection history maintenance with memory resource conservation.

AI summary

A first communication may be configured to, in a case where first communication information for establishing a first wireless connection between the first communication device and a second communication device is obtained and fixed identification information of the second communication device is received from the second communication device, store, in the memory, the first communication information and the identification information in association with each other, and in a case where variable second communication information for establishing a second wireless connection between the first communication device and the second communication device is obtained and the identification information is received from the second communication device after the first wireless connection has been disconnected, delete, from the memory, the first communication information which is associated with the identification information and store, in the memory, the second communication information in association with the identification information.
