Wireless Communication Service Discovery Across Modes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems are limited in detecting and acquiring service information from devices operating in different communication modes, as they can only detect devices in the same mode and lack comprehensive service information from surrounding devices.
Innovation Solution
A wireless communication system where devices transmit service or application information using a protocol that allows communication regardless of the mode, enabling devices to collect and share information across different communication modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a wireless communication device operates in a specific communication mode (e.g., STA mode, AP mode, Wi-Fi direct mode), then it can perform wireless communications in that mode, but it can only detect and acquire service information from devices operating in the same mode, limiting the scope of detectable devices
Solution Approach 1:
The patent introduces a universal service information transmission mechanism that acts as an intermediary between devices in different communication modes. Service information is transmitted using a protocol that can be received by devices regardless of their current communication mode setting, enabling cross-mode service discovery without requiring devices to switch modes or use mode-specific protocols
Solution Approach 2:
The patent implements a universal service information transmission capability that works across multiple communication modes simultaneously. The service information transmission function is designed to be mode-agnostic, allowing a single mechanism to serve devices in STA mode, AP mode, Wi-Fi direct mode, and other modes without requiring separate implementation for each mode
2Measurement precision
If a wireless communication device uses mode-specific service discovery protocols (e.g., SDP for Wi-Fi direct), then it can acquire service information from devices in the same mode, but it cannot acquire service information from devices operating in different modes
Solution Approach 1:
The patent changes the parameter of protocol compatibility by designing service information transmission to use a universal protocol format that can be interpreted by devices regardless of their communication mode. This allows service information to be transmitted with consistent structure and semantics across different communication modes, enabling accurate service discovery without mode-specific adaptations
3Reliability
If a wireless communication system requires devices to be in the same communication mode for service discovery, then service information can be reliably acquired, but the user must manually switch communication modes to access services from devices in different modes, reducing convenience
Solution Approach 1:
The patent enables the wireless communication device to automatically perform service discovery across different communication modes without requiring user intervention for mode switching. The device autonomously transmits and receives service information using a universal protocol, automatically adapting to devices in any communication mode and presenting a unified service list to the user, thereby eliminating manual mode switching operations

AI summary
Each of wireless communication devices 2A, 2B and 2C is configured in such a way as to transmit information about either a service or an application which the wireless communication device can provide, in accordance with a protocol which makes it possible to perform wireless communications with a wireless communication device 1 regardless of the setting of a communication mode to the wireless communication device 1, and the wireless communication device 1 is configured in such a way as to collect information about an application which is transmitted from each of the wireless communication devices 2A, 2B and 2C. As a result, the wireless communication device 1 can acquire the information about the providable application from each of the wireless communication devices 2A, 2B and 2C existing in the surroundings thereof regardless of the setting of a communication mode.
