Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication devices face challenges in establishing a reliable wireless link with external devices using NFC, particularly in scenarios where P2P mode is not supported, leading to unstable connections and difficulties in establishing Wi-Fi connections.
Innovation Solution
A communication device with a wireless interface that sequentially operates in multiple states, adjusting polling signal timing and mode configurations to enable P2P or R/W-CE links, and extending the Target time period to improve connection reliability and speed up the establishment of Wi-Fi connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wireless interface uses a fixed predetermined time period for the second state, then the operation is simple, but the connection reliability is poor when external devices do not support P2P mode
Solution Approach 1:
The patent implements dynamic adjustment of the second predetermined time period based on detection information from polling signals. The controller extends the time period when P2P mode is not supported to allow sufficient time for CE mode connection establishment, while maintaining the original shorter duration when P2P mode is supported for faster connection. This dynamic timing adjustment resolves the contradiction between connection reliability and operation simplicity.
2Reliability
If the second predetermined time period is extended to improve connection reliability, then the connection stability improves, but the time required for establishing wireless link increases
Solution Approach 1:
The patent dynamically adjusts the second predetermined time period based on the operational mode of the external device. When P2P mode is detected as unsupported, the time period is extended to ensure reliable CE mode connection. When P2P mode is supported, the original shorter time period is maintained for rapid connection establishment. This conditional dynamic adjustment optimizes both connection stability and establishment time.
3Adaptability or versatility
If the wireless interface operates only in P2P mode, then the connection speed is fast, but compatibility with external devices is reduced
Solution Approach 1:
The patent implements multi-functionality in the wireless interface by supporting both P2P mode and CE mode operations. The interface automatically detects the capabilities of external devices and switches between modes accordingly. This universal approach ensures compatibility with various devices while maintaining fast connection speeds through intelligent mode selection, resolving the contradiction between adaptability and productivity.

AI summary
The communication device may include a wireless interface configured to repeat operating sequentially in a plurality of states including a first state and a second state, a processor and a main memory. The communication device may acquire detection information from the wireless interface in a case where the wireless interface operating in the second state receives a second polling signal from a specific external device. The communication device may supply a specific signal to the wireless interface in a case where the detection information is acquired from the wireless interface operating in the second state, the specific signal being for causing the wireless interface to use, as a duration time period of the second state, a specific time period instead of the second predetermined time period, the specific time period being longer than the second predetermined time.
