Communication Apparatus Concurrent Mode Control Timeout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses face challenges in concurrently maintaining wireless connections in infrastructure and peer-to-peer modes, particularly when the connection processing of one mode interferes with the other, leading to prolonged or failed establishment of wireless networks, especially when the power of the access point is turned off or immediately after activation.
Innovation Solution
A communication apparatus with a control unit that manages concurrent wireless communication modes by activating the peer-to-peer mode if the infrastructure mode connection is not established within a predetermined time, ensuring seamless operation and reducing the influence of one mode's connection processing on the other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication apparatus waits for infrastructure mode connection to be established before activating peer-to-peer mode, then the infrastructure mode connection can be properly set up, but the peer-to-peer mode activation is delayed or fails when the access point is off or recently activated
Solution Approach 1:
The communication apparatus performs preliminary actions by attempting to establish infrastructure mode connection first, but simultaneously prepares for and activates peer-to-peer mode as a backup if the infrastructure connection fails within a predetermined time period. This preliminary action approach ensures that peer-to-peer mode can take over quickly when infrastructure mode cannot establish connection.
Solution Approach 2:
The system dynamically switches between infrastructure mode and peer-to-peer mode based on connection establishment success. The control unit monitors the connection status and automatically transitions to peer-to-peer mode when infrastructure mode fails, creating a dynamic adaptation to changing network conditions.
2Device complexity
If the communication apparatus uses a common channel for both infrastructure mode and peer-to-peer mode, then device complexity is reduced, but connection establishment fails when the access point is off or recently activated
Solution Approach 1:
The control unit performs preliminary assessment of infrastructure mode connection status before committing to using a common channel for peer-to-peer mode. If infrastructure connection fails within the predetermined time, the system preliminarily switches to peer-to-peer mode with alternative channel selection, ensuring connection reliability without requiring complex pre-configuration of multiple channels.
3Stability of the object's composition
If the communication apparatus processes infrastructure mode connection first before peer-to-peer mode, then infrastructure mode connections are stable, but peer-to-peer mode activation is prolonged or impossible when infrastructure connection takes too long
Solution Approach 1:
The system executes preliminary infrastructure mode connection processing with a predetermined time limit. If the connection is not established within this time frame, the system immediately activates peer-to-peer mode without further delay. This preliminary action with time constraint ensures both infrastructure stability when available and rapid peer-to-peer activation when needed.
Solution Approach 2:
When infrastructure mode connection fails to establish within the predetermined time, the system skips further infrastructure mode processing and rushes to activate peer-to-peer mode immediately. This skipping mechanism prevents prolonged waiting and ensures rapid activation of the alternative communication mode.

AI summary
A communication apparatus has a communication function for performing wireless communication using one of a first mode of performing first communication with a partner apparatus via another apparatus, a second mode of performing second communication with the partner apparatus not via another apparatus, and a third mode of concurrently performing the first communication and the second communication. When the third mode is the operation mode of the communication function, the communication apparatus controls the communication function so as to activate a function of the second communication after executing processing to establish a connection for the first communication. When the connection has not been established even after a predetermined time has elapsed since the start of connection processing for the first communication, the function for the second communication is activated even if the connection for the first communication has not been established.
