Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices experience excessively long search times or search failures when projecting due to unstable network environments, leading to reduced search efficiency and user experience.
Innovation Solution
A communication system and method utilizing short-range wireless communication to establish connections between electronic devices, enabling them to send and receive multicast or broadcast search request messages with projection identifiers, allowing for simultaneous two-way searches and independent message transmissions to enhance search efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electronic devices perform searches using existing methods in unstable network environments, then the search process can be initiated, but the search success rate decreases and search time becomes excessively long due to packet loss
Solution Approach 1:
The patent applies preliminary action by establishing a short-range wireless connection before performing the search. The transmit end device and receive end device pre-establish a reliable communication channel through short-range wireless communication (such as Bluetooth or NFC), ensuring that subsequent search messages are transmitted reliably without packet loss, thus improving both search success rate and reducing search time
Solution Approach 2:
The patent uses short-range wireless communication as an intermediary channel between devices. Instead of directly searching over an unstable network, devices first communicate through a stable short-range connection to exchange search requests and responses, acting as a reliable mediator that eliminates packet loss issues
2Productivity
If electronic devices perform traditional searches, then the search process can be completed, but the search efficiency is low when network environment is unstable
Solution Approach 1:
The patent performs preliminary action by establishing a short-range wireless connection before the search operation. This pre-established connection provides a stable communication foundation, ensuring that search messages are transmitted efficiently without being affected by network instability, thereby improving search efficiency
Solution Approach 2:
The patent extracts the search operation from the unstable network environment and relocates it to a stable short-range wireless communication channel. By separating the search process from the unreliable network, the system achieves high search efficiency regardless of network conditions

AI summary
This application relates to the field of terminal technologies, and provides a communication system and a communication method. The method includes: A first electronic device and a second electronic device respectively send a first search request message and a second search request in a multicast or broadcast manner in response to establishment of a connection in a first short-range wireless communication manner. The first search request message multicast or broadcast by the first electronic device includes first identification information, and the second search request message multicast or broadcast by the second electronic device includes second identification information. After the first electronic device receives the second search request message or the second electronic device receives the first search request message, display may be performed based on the identification information in the search request message. This can effectively reduce a probability of a projection search failure, improve device projection search efficiency, shorten projection search time, and improve user experience.
