Communication Apparatus Master Station Disconnection Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When a master station device disconnects from a wireless network, existing communication systems face challenges in enabling seamless communication of target data between the master station and slave station devices without relying on the access point.
Innovation Solution
A communication apparatus that receives and registers identification information of slave station devices, allowing it to establish a new wireless network and transmit commands to facilitate communication of target data even after the master station's disconnection, by using a processor to execute specific commands and establish a new wireless network configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the master station device is disconnected from the wireless network, then the existing communication system cannot maintain communication between slave station devices, but the patent enables continuous communication by establishing a new wireless network
Solution Approach 1:
The communication apparatus pre-registers identification information of slave station devices in its memory during normal network operation. When the master station disconnects, this pre-stored information enables the apparatus to immediately establish a new wireless network without requiring real-time discovery or complex configuration procedures, thus maintaining communication continuity while managing complexity.
2Productivity
If the communication apparatus establishes a new wireless network to communicate with the first device, then communication can continue without the master station, but this requires additional network configuration and management
Solution Approach 1:
The communication apparatus acts as an intermediary by assuming the master station's role in managing the wireless network. It uses the pre-registered identification information to directly manage and coordinate communication between slave station devices, eliminating the need for complex peer-to-peer negotiation and simplifying network management while maintaining data transfer capability.
3Reliability
If the system uses the master station for all communication coordination, then network management is centralized and simple, but communication fails when the master station is disconnected
Solution Approach 1:
The system performs preliminary actions by having the communication apparatus register and store identification information of all slave station devices during normal operation. This preparation ensures that when the master station disconnects, the apparatus can immediately take over network management using the pre-stored information, maintaining both communication availability and operational simplicity without requiring real-time reconfiguration.

AI summary
A communication apparatus includes: a processor execute receiving identification information of a first device of the slave station devices from the first device through the master station device; transmitting, in a specific case where the master station device is disconnected from the first wireless network and a specific instruction to perform communication of target data with the first device is provided, transmits a first type command to the first device by using the identification information, the first type command being a command for establishing a state where a transmission source device and a transmission destination device belong to a same wireless network; establishing, when the first type command is transmitted to the first device, a specific state, and performing, when the specific state has been established, communication of the target data with the first device by using the second wireless network.
