Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication apparatuses operating as parent stations in wireless networks face challenges in realizing different purposes when external apparatuses participate as child stations, leading to inadequate fulfillment of desired objectives.
Innovation Solution
A communication apparatus with dual wireless interfaces (Wi-Fi and NFC) and a processor, capable of establishing separate wireless networks for different purposes, allowing it to operate as both a Soft AP and a Group Owner, enabling it to manage connections and data transfer efficiently while preventing interference between purposes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a communication apparatus operates as a single parent station in a wireless network, then it can establish wireless connections with external apparatuses, but it cannot simultaneously fulfill multiple different purposes when external apparatuses participate as child stations
Solution Approach 1:
The communication apparatus is divided into multiple parent station functions operating on different wireless interfaces. The first parent station (Soft AP) handles one purpose while the second parent station (WFD G/O) handles another purpose, allowing simultaneous fulfillment of multiple different purposes without interference between them.
Solution Approach 2:
The communication apparatus is designed to perform multiple parent station functions simultaneously through different wireless interfaces. It can operate as both a Soft AP parent station and a WFD G/O parent station, making it universally adaptable to serve multiple different purposes at the same time.
2Adaptability or versatility
If a communication apparatus uses a single wireless interface for parent station operation, then it simplifies the interface configuration, but it cannot establish separate wireless networks for different purposes
Solution Approach 1:
The wireless communication functionality is segmented across multiple interfaces: the first wireless interface (Wi-Fi) is dedicated to Soft AP parent station operation, while the second wireless interface (WFD) is dedicated to WFD G/O parent station operation. This segmentation allows separate wireless networks for different purposes without interface conflicts.
3Reliability
If external apparatuses participate in a wireless network as child stations, then they can communicate with the parent station, but the parent station may not be able to appropriately realize different purposes due to network conflicts
Solution Approach 1:
The network is segmented into separate domains: one wireless network for Soft AP operations and another for WFD G/O operations. Each external apparatus connects to the appropriate network based on its intended purpose, eliminating network conflicts and ensuring reliable purpose realization without interference.

AI summary
A communication apparatus may include: a first wireless interface; a second wireless interface; a processor. The communication apparatus may perform: in a case where a first communication link via the second wireless interface is established with a first external apparatus while the communication apparatus operates as a first parent station of a first wireless network, operating as a second parent station of a second wireless network different from the first wireless network, each of the first wireless network and the second wireless network being for performing a wireless communication via the first wireless interface; and after the communication apparatus has started an operation as the second parent station, establishing a wireless connection via the first wireless interface with the first external apparatus so as to cause the first external apparatus to participate as a child station in the second wireless network.
