P2P WiFi Group Creation with Embedded Credentials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting mobile devices to smart TVs require complex cable setups and cumbersome negotiation processes, disrupting existing wireless connections and complicating content sharing.
Innovation Solution
A method and device that create a peer-to-peer (P2P) group over a wireless local area network, where a first terminal generates and broadcasts a unique SSID and connection password within a Probe Request frame, allowing a second terminal to connect directly without prior connection establishment, thus simplifying the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional P2P connection methods are used, then data transmission between terminals is enabled, but complex cable setups and cumbersome negotiation processes are required
Solution Approach 1:
The patent embeds the SSID and connection password in advance within the Probe Request frame, so that when the second terminal receives this frame, it already possesses the necessary connection information to directly connect to the P2P group without undergoing complex negotiation processes. This preliminary embedding of connection credentials resolves the contradiction by simplifying the connection operation while maintaining secure P2P data transmission capability.
2Adaptability or versatility
If conventional P2P connection methods are used, then direct device connection is achieved, but existing wireless connections are disrupted
Solution Approach 1:
The patent creates a separate P2P group with its own SSID and connection password that operates independently from existing wireless connections. By segmenting the connection into a dedicated P2P network group, the system enables direct device-to-device communication while maintaining the stability and continuity of other wireless connections, thus resolving the contradiction between connection flexibility and wireless connection stability.
3Reliability
If terminals search for each other to establish connection, then connection is established, but time-consuming search and negotiation processes occur
Solution Approach 1:
The first terminal proactively embeds its SSID and connection password within the Probe Request frame before the second terminal needs to connect. This preliminary inclusion of connection credentials eliminates the need for time-consuming search and negotiation processes, as the second terminal receives all necessary information in a single frame and can immediately establish the connection, thereby resolving the contradiction between reliable connection establishment and connection setup time.

AI summary
The embodiments of the present disclosure provide a method and device for connection, in which a first terminal may create (S101) a P2P group, and then send (S103) an SSID and a connection password of the P2P group to a second terminal, or set the SSID and the connection password of the P2P group as an SSID and a connection password provided by the smart television. In this way, prior to establishment of a connection, the SSID and the connection password may have been transmitted, and the smart television may acquire the SSID and the connection password of the P2P group created by the mobile terminal, thus the SSID and the connection password may be used to directly connect the smart television with the terminal equipment without cumbersome search and negotiation processes in establishment of a conventional P2P connection.
