Wireless Communication Apparatus Parent Station Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In ad hoc wireless network systems, communication apparatuses face challenges in maintaining connectivity and reducing power consumption when a wireless connection between devices is disconnected, particularly when operating as child stations under a parent station.
Innovation Solution
A communication apparatus is designed to determine disconnection situations and form a new wireless network where it operates as a parent station, using stored wireless profiles to re-establish connectivity with other apparatuses, thereby reducing power consumption and ensuring continuous communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the first communication apparatus operates as a child station in the first wireless network, then power consumption is reduced and network management is simplified, but connectivity is lost when the parent station (third communication apparatus) disconnects
Solution Approach 1:
The first communication apparatus stores a wireless profile (including authentication credentials and network parameters) in its memory before disconnection occurs. This preliminary action enables the apparatus to quickly re-establish connectivity by switching to parent station mode and using the pre-stored profile, rather than needing to re-authenticate or reconfigure network parameters after disconnection.
Solution Approach 2:
The first communication apparatus dynamically switches its operational role between child station and parent station modes. When connected to the third communication apparatus, it operates as a child station to save power. When disconnection is detected, it transitions to parent station mode to maintain connectivity with the second communication apparatus, thus adapting its function based on network conditions.
2Reliability
If the first communication apparatus switches to parent station mode to maintain connectivity, then communication reliability is improved, but device complexity and power consumption increase
Solution Approach 1:
The first communication apparatus is designed with multi-functionality, capable of operating in both child station and parent station modes. This universal design allows a single device to fulfill multiple roles in the wireless network, eliminating the need for separate hardware configurations and simplifying the overall system architecture while maintaining communication reliability.
Solution Approach 2:
The wireless profile is pre-stored in the memory of the first communication apparatus before any mode switching occurs. This preliminary preparation includes authentication credentials, network parameters, and configuration data, which eliminates the need for complex real-time configuration when transitioning between modes, thereby reducing operational complexity.
3Loss of time
If the first communication apparatus stores wireless profile information, then reconnection speed is improved, but memory requirements and device complexity increase
Solution Approach 1:
The wireless profile containing authentication credentials, SSID, security parameters, and network configuration data is stored in the memory of the first communication apparatus before disconnection. This preliminary storage action enables immediate reconnection without time-consuming re-authentication or reconfiguration processes, significantly reducing reconnection time.
Solution Approach 2:
The first communication apparatus creates and stores a copy of the wireless profile information from the first wireless network in its own memory. This copied profile includes all necessary authentication and configuration data, allowing the apparatus to quickly re-establish connectivity by using this pre-copied information rather than requesting it again after disconnection.

AI summary
A first communication apparatus may comprise a memory configured to store a wireless profile being used in a first wireless network in a case where the first communication apparatus operates as a child station of the first wireless network. The first communication apparatus may determine, after the first wireless network in which each of the first communication apparatus and a second communication apparatus operates as a child station and a third communication apparatus operates as a parent station has been formed, whether a wireless connection between the first and third communication apparatuses is disconnected, and form a second wireless network in which the wireless profile is used in a case where it is determined that the wireless connection is disconnected, the second wireless network being a network in which the first communication apparatus operates as a parent station and the second communication apparatus operates as a child station.
