Solution Overview
Problem
Existing communication systems face disruptions when switching from Internet-connected access point communication to peer-to-peer (P2P) mode, leading to interrupted Internet connectivity and reduced customer convenience.
Innovation Solution
A communication apparatus that acquires information through near field communication to determine if a target device is connected to an access point, and if not, establishes a P2P connection, ensuring seamless transition and maintaining Internet connectivity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If the communication apparatus switches to P2P connection when a target apparatus is detected through NFC, then the connection establishment speed is improved, but the Internet connectivity is interrupted
Solution Approach 1:
The communication apparatus performs preliminary actions by acquiring communication information (SSID, password, IP address) from the target apparatus through NFC before establishing the actual wireless connection. This preliminary data acquisition enables the apparatus to pre-configure connection parameters and maintain infrastructure mode connectivity while still benefiting from the fast connection establishment of P2P mode.
Solution Approach 2:
NFC acts as an intermediary technology that enables fast discovery and information exchange between devices without immediately triggering a full wireless connection switch. The NFC-based communication information acquisition serves as a bridge, allowing the system to prepare for P2P connection while preserving infrastructure mode Internet connectivity through the access point.
2Ease of operation
If the communication apparatus always uses P2P connection mode, then the ease of operation is improved, but the adaptability to different network conditions deteriorates
Solution Approach 1:
The communication apparatus dynamically adjusts its connection mode based on real-time detection of target apparatuses through NFC. When a target apparatus is detected, the system transitions to P2P mode for ease of direct connection. When no target apparatus is detected or infrastructure mode provides better connectivity, the system uses access point mode. This dynamic switching optimizes both ease of operation and adaptability to different network conditions.
Solution Approach 2:
The system changes operational parameters by switching between P2P connection mode and infrastructure mode based on detection results. The determination unit evaluates whether to use P2P mode by checking for the presence of target apparatuses, and adjusts the connection parameter accordingly. This parameter change enables the system to adapt to varying network conditions while maintaining user-friendly operation.
3Stability of the object's composition
If the communication apparatus waits for P2P connection to end before allowing Internet access, then the connection stability is improved, but the loss of time increases
Solution Approach 1:
The communication apparatus performs preliminary action by acquiring all necessary communication information (SSID, password, IP address, gateway) from the target apparatus through NFC before establishing the wireless connection. This preliminary data acquisition eliminates the need to wait for connection establishment before accessing the Internet, as the apparatus already has the required parameters to immediately establish infrastructure mode connectivity for Internet access.

AI summary
A communication apparatus capable of performing near field communication acquires communication information of a target apparatus through the near field communication, determines whether or not the target apparatus is connected to an access point to which the communication apparatus is connected, on the basis of the communication information, and accepts the target apparatus as a target to which the communication apparatus is to be connected by using a peer-to-peer communication system, when it is determined that the target apparatus is not connected to the access point to which the communication apparatus is connected.
