Communication Apparatus Search Method Power Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication apparatuses that search for other devices using both peer-to-peer (P2P) and basic service set (BSS) search methods unnecessarily consume power when both methods detect the same device, as they continue to search simultaneously.
Innovation Solution
Implementing a control unit that determines which search method to use based on connection status, switching to P2P search when not connected to an access point (AP) and BSS search when connected, and ceasing unnecessary searches once a device is detected that meets predetermined conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication apparatus searches for opposing devices by both P2P search function and BSS search function simultaneously, then the advantage is that opposing devices not detected by one method can be detected by the other, but the disadvantage is that power is unnecessarily consumed when the same device is detected by both methods
Solution Approach 1:
The system dynamically adjusts the search strategy based on connection status. When connected to an AP, it performs BSS search; when not connected, it performs P2P search. This dynamic adaptation resolves the contradiction by selecting the appropriate search method rather than running both simultaneously, reducing power consumption while maintaining detection effectiveness.
Solution Approach 2:
The invention changes the operational parameters of the search function based on connection status. By switching between P2P and BSS search modes depending on whether the device is connected to an AP, it optimizes the search process to avoid redundant detections and reduce power consumption while maintaining comprehensive device discovery.
2Reliability
If the communication apparatus always searches for opposing devices by both search methods, then comprehensive device detection is achieved, but search processing time is extended due to redundant searches
Solution Approach 1:
The system dynamically selects the search method based on connection status, switching between P2P and BSS search modes. This dynamic approach eliminates redundant searches while maintaining comprehensive device detection coverage, thereby reducing search processing time without sacrificing detection completeness.
3Reliability
If both search methods are performed simultaneously, then the advantage is that more opposing devices can be detected, but the disadvantage is that device complexity increases due to coordinated search management
Solution Approach 1:
The invention extracts the search coordination complexity by separating the search methods into mutually exclusive modes based on connection status. Instead of managing both P2P and BSS searches simultaneously, the system selects one method based on whether the device is connected to an AP, thereby reducing coordination complexity while maintaining effective device detection.
4Use of energy by moving object
If the communication apparatus uses P2P search when not connected to AP and BSS search when connected, then power consumption is reduced, but the capability to detect devices via alternative methods is limited
Solution Approach 1:
The system changes the search method parameter based on connection status, selecting P2P search when disconnected and BSS search when connected to an AP. This parameter-based selection achieves power saving performance while maintaining adaptability by appropriately matching the search method to the current network environment.

AI summary
A communication apparatus searches for another communication apparatus using either a method with which to perform direct wireless communication or a method for specifying a service via an apparatus for constructing a wireless network, and in a case where another communication apparatus is using one of the methods and the detected another communication apparatus satisfies a predetermined condition, the communication apparatus does not perform a search using the other method.
