Multi-Channel Device Discovery to Avoid Connection Collisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-screen collaboration technologies face challenges in device discovery and connection, particularly in the field of communication, where existing technologies have not efficiently addressed the need for device discovery and connection, particularly in the field of communication, where devices at two ends are unknown, leading to inefficient and time-consuming random collision, and poor user experience.
Innovation Solution
The method involves optimizing device communication by using the method of device discovery and connection by using a first device to receive discovery and connection request signaling of a second device on a first channel, where the first channel is used by the first device to communicate with a third device, and sending discovery request response signaling to the second device, thereby improving the efficiency of the method.

Engineering Contradiction Analysis
1Loss of time
If devices perform discovery and connection through random channel collision, then device compatibility is maintained, but device discovery and connection time increases significantly
Solution Approach 1:
The patent introduces a third device as an intermediary that receives discovery request signaling from the second device on the first channel and forwards it to the first device. This mediator resolves the channel misalignment problem by enabling indirect communication between devices that are not on the same channel, thereby reducing discovery time and improving connection efficiency without requiring random channel collision
Solution Approach 2:
The patent adds a network dimension to the traditional direct peer-to-peer discovery approach. By enabling discovery request signaling to be routed through a third device on a different channel, the system transitions from a single-channel direct communication model to a multi-channel indirect communication model, effectively solving the channel alignment problem and reducing discovery time
2Reliability
If devices use the same channel for communication, then communication reliability is improved, but channel availability and flexibility are reduced
Solution Approach 1:
The patent segments the discovery and connection process into distinct phases: discovery request signaling phase (using first channel through third device), discovery response phase, and connection establishment phase. This segmentation allows different channels to be used for different phases, maintaining reliability during critical communication phases while providing flexibility in channel selection across the overall process

AI summary
A device communication method includes receiving discovery request signaling on a first channel, where the discovery request signaling is used by a second terminal to request device discovery; sending discovery request response signaling to the second terminal; and receiving connection request signaling, and sending first control signaling, where the first control signaling includes at least first indication information, and the first indication information indicates the second device to establish a connection on the first channel. A first device operates on the first channel in a first time period group. The first device operates on a second channel in a second time period group. A plurality of time periods in the first time period group and a plurality of time periods in the second time period group alternate in sequence in time domain.
