Wi-Fi Direct Network Management for Communication Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wi-Fi Direct networks are often left active after service communication ends, leading to unnecessary resource consumption and decreased usability due to potential interference with other communications, and vice versa, where ending the network disrupts ongoing service communications.
Innovation Solution
A communication apparatus with determination and leaving means to assess whether it joined a Wi-Fi Direct network prior to service initiation and process leaving the network accordingly when the service ends, ensuring appropriate network management based on usage circumstances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the Wi-Fi Direct network is ended when the service communication ends, then the resource consumption is reduced, but it is not possible to continue the other service communication
Solution Approach 1:
The system changes the state parameter of the Wi-Fi Direct network from active to inactive based on service communication status. When service communication ends, the network is ended to reduce resource consumption; when other communications are detected, the network is re-established to maintain connectivity. This dynamic parameter change resolves the contradiction between energy saving and communication continuity.
Solution Approach 2:
The Wi-Fi Direct network transitions from a static state to a dynamic state where it can be established and ended based on real-time service communication needs. The system dynamically monitors whether service communication is active and adjusts the network state accordingly, allowing the network to adapt between being active (when needed) and inactive (to save resources), thus resolving the contradiction.
2Adaptability or versatility
If the Wi-Fi Direct network is not ended when the service communication ends, then the other service communication can continue, but the resources of the apparatus are unnecessarily consumed
Solution Approach 1:
The system changes the state parameter of the Wi-Fi Direct network from active to inactive based on service communication status. When service communication ends, the network is ended to reduce resource consumption; when other communications are detected, the network is re-established to maintain connectivity. This dynamic parameter change resolves the contradiction between energy saving and communication continuity.
Solution Approach 2:
The system extracts the essential function of the Wi-Fi Direct network (enabling service communication) and separates it from the network itself. When service communication is not needed, only the network connection is ended while preserving the capability to re-establish it quickly when needed. This extraction allows the system to save resources without permanently losing the ability to communicate.
3Ease of operation
If a new Wi-Fi Direct network is established when no network exists, then the service communication can be implemented, but the processing load increases
Solution Approach 1:
The system performs preliminary action by checking whether a Wi-Fi Direct network already exists before initiating service communication. This advance check prevents unnecessary network establishment processes, reducing processing load. When a network already exists, the system can directly use it for service communication, avoiding the overhead of creating a new network and thereby resolving the contradiction between ease of operation and device complexity.

AI summary
A communication apparatus includes a determination unit configured to determine whether the communication apparatus has joined a wireless network established with another communication apparatus prior to start of a predetermined service, and a leaving unit configured to perform processing for leaving the wireless network according to a result of determination by the determination unit when the predetermined service ends.
