BLE Discovery for Wi-Fi Direct Service Intention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wi-Fi Direct technology lacks the ability to determine the receiving terminal's intention regarding file or service reception before establishing a connection, leading to potential unwanted file or service transfer after connection is established.
Innovation Solution
Implementing Bluetooth Low Energy (BLE) discovery mechanisms within Wi-Fi Application Service Platforms to enable two-way message exchanges that allow for the transmission of file attribute information and user intention confirmation before establishing a Wi-Fi Direct connection, using BLE service advertising packets and Wi-Fi P2P discovery methods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If Wi-Fi Direct device discovery and service discovery are performed before connection establishment, then devices can find each other and identify supported services, but the receiving terminal cannot determine user intention to receive files or services until after connection is established
Solution Approach 1:
The patent applies preliminary action by having the receiving terminal send a reception intention notification frame during the P2P connection establishment phase, before actual file transfer begins. This allows the transmitting terminal to know in advance whether the receiving terminal wants to accept files, eliminating the need for post-connection cancellation and preventing wasted transmission resources.
2Object-generated harmful factors
If the receiving terminal cancels reception during file transmission after connection establishment, then unwanted files can be rejected, but data transmission efficiency is reduced and battery life is consumed
Solution Approach 1:
The patent applies preliminary anti-action by having the receiving terminal proactively send a reception intention notification frame indicating whether it wants to receive files before the transmitting terminal begins file transmission. This prevents unwanted file transfers from occurring in the first place, eliminating the need for cancellation during transmission and avoiding the energy waste associated with interrupted transfers.
3Use of energy by moving object
If Bluetooth Low Energy discovery is used for initial device discovery, then power consumption is reduced and discovery speed is improved, but additional message exchange protocols are required
Solution Approach 1:
The patent merges Bluetooth Low Energy discovery with Wi-Fi P2P connection establishment by using BLE for initial device discovery and service identification, then seamlessly transitioning to Wi-Fi P2P for the actual connection. The BLE advertisement frames include Wi-Fi P2P interface information, allowing the seeking terminal to directly initiate Wi-Fi connection without lengthy re-discovery processes, thus reducing overall power consumption while managing protocol complexity through integration.
