Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inefficiency in establishing wireless connections due to large quantities of similar device identifiers in search results, leading to increased user time in selection and reduced connection speed and data transmission efficiency.
Innovation Solution
A method where a first device generates and provides connection information to a second device, allowing the second device to calculate and verify authentication information, enabling secure and efficient wireless connection establishment through probe requests and authentication modes like 4-way handshake or WPS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If device search results include identifiers of multiple devices of the same type, then the user can find the target device, but the user needs to spend a long time in distinguishing and selecting the appropriate device
Solution Approach 1:
The patent applies preliminary action by pre-generating connection information and calculating identifiers before the actual connection process. The first device generates connection information containing its identifier, and both devices calculate identifiers from this information in advance, so that when devices are discovered, the identification process is already prepared and can proceed quickly without manual searching.
Solution Approach 2:
The patent introduces connection information as an intermediary element that mediates the device discovery and selection process. Instead of directly comparing device identifiers in search results, the system uses calculated identifiers derived from connection information as an intermediate step, enabling automatic matching and eliminating the need for manual device selection.
2Productivity
If manual device selection is required from search results, then connection can be established, but the speed of establishing wireless connection is reduced
Solution Approach 1:
The patent implements self-service by enabling devices to automatically generate and verify connection information without user intervention. The first device generates connection information and calculates its identifier, the second device obtains this information, calculates its own identifier from the same data, and both devices automatically verify matching. This self-identifying mechanism eliminates manual selection and accelerates connection establishment.
Solution Approach 2:
The patent uses feedback by having the second device send a probe request containing its calculated identifier back to the first device, which then verifies whether this identifier matches its own calculated identifier. This feedback loop enables automatic verification and confirmation of the connection target, replacing manual selection with an automated verify-and-connect process.
3Measurement precision
If device identifiers are similar, then devices of the same type can be identified, but the user has difficulty in distinguishing the correct device
Solution Approach 1:
The patent applies parameter changes by transforming device identifiers through a calculation process. Instead of using raw device identifiers directly for matching, the system calculates new identifiers from connection information using a consistent algorithm on both devices. This transformation changes the parameter representation, ensuring that even if original identifiers are similar, the calculated identifiers will uniquely and accurately identify the connection target.

AI summary
Embodiments of the present invention relate to the communications field, and provide a method and a device for establishing a wireless connection. The method includes: after receiving an operation instruction of a first user, generating, by the first device, connection information according to the operation instruction, and providing the connection information to a second device near the first device, so that the second device generates or obtains a first identifier through calculation according to a first information portion of the connection information by using a preset algorithm; receiving a first message that is sent by the second device according to the connection information, where the first message carries the first identifier; determining whether the first identifier matches a second identifier of the first device, where the second identifier is equal to or corresponds to a result that is generated through calculation according to the first information portion; if the first identifier matches the second identifier, sending a second message to the second device; and establishing a wireless connection to the second device. The present invention can improve efficiency of establishing a wireless connection.
