Bluetooth-Assisted Wi-Fi Direct Pairing for Stable Peer Connections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi direct communication technologies face inefficiencies in establishing stable and efficient peer-to-peer connections between devices, particularly in terms of connection setup time and reliability, especially when persistent group connections are required.
Innovation Solution
The electronic device employs a Bluetooth communication interface to exchange pairing state information with an external device, compares this information to determine the need for releasing or establishing a new Wi-Fi direct peer-to-peer connection, and generates a new group based on the comparison result, thereby optimizing the connection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If Wi-Fi direct connection is established without checking pairing state information, then connection setup is faster, but connection reliability and stability deteriorate
Solution Approach 1:
The patent applies preliminary action by checking pairing state information through Bluetooth communication before establishing the Wi-Fi direct connection. The electronic device transmits a pairing state request to the external device, receives pairing state response information, and compares the pairing states before finalizing the connection. This preliminary verification ensures connection reliability while the efficient comparison process minimizes time loss.
2Stability of the object's composition
If pairing state information is exchanged and compared before connection, then connection stability improves, but device complexity increases
Solution Approach 1:
The patent applies universality by using the Bluetooth communication interface for multiple purposes: both for initial device pairing and for subsequent pairing state verification before Wi-Fi direct connection. This multi-functional use of Bluetooth simplifies the overall system architecture by avoiding the need for separate dedicated verification mechanisms, thereby reducing device complexity while maintaining connection stability.
Solution Approach 2:
The patent implements feedback by having the electronic device transmit pairing state request information to the external device, receive pairing state response information containing the external device's pairing state, and compare the two pairing states. This feedback loop ensures that both devices are in the same pairing state before establishing the Wi-Fi direct connection, thereby ensuring stability without requiring complex verification procedures.
3Adaptability or versatility
If existing Wi-Fi direct connection is used without group management, then connection establishment is simpler, but adaptability for persistent connections deteriorates
Solution Approach 1:
The patent applies preliminary action by checking whether a persistent group already exists between the electronic device and the external device before establishing a new Wi-Fi direct connection. The processor determines if the external device is included in a persistent group and, if so, uses the existing group information to establish the connection. This preliminary check enables adaptability for persistent connections while avoiding the complexity of creating and managing new groups when they already exist.
