Dynamic Access Point Switching for Stable Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems in smart home environments face instability and security issues due to fluctuations in access point connectivity and lack of robust authentication processes, leading to data transmission interruptions and potential security breaches.
Innovation Solution
A method and apparatus for transmitting data that dynamically switches between a primary access point and a secondary access point based on their online status, with the secondary access point having a lower data transmission rate but higher security and stability, ensuring continuous data transmission and enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data transmission uses a high-speed access point, then data transmission rate is improved, but network stability and security deteriorate
Solution Approach 1:
The patent divides the access point system into multiple independent access points (first access point for high-speed transmission, second access point for stable transmission). Each access point serves specific transmission needs, allowing the system to segment the contradiction between speed and stability by using different access points for different purposes.
Solution Approach 2:
The patent implements dynamic switching between access points based on real-time connectivity status. The system dynamically determines which access point to use by detecting online/offline states, making the transmission path flexible and adaptive rather than fixed, thus resolving the contradiction through dynamic resource allocation.
2Reliability
If data transmission switches to a secondary access point when primary is offline, then network stability is improved, but data transmission rate deteriorates
Solution Approach 1:
The patent establishes multiple access points and their connectivity statuses in advance. The system pre-configures the switching mechanism and maintains awareness of which access points are available, so when the primary access point goes offline, the transition to the secondary access point can be executed smoothly without significant transmission rate penalty.
Solution Approach 2:
The patent introduces a control mechanism as an intermediary that manages the switching between access points. This intermediary coordinates the transition from primary to secondary access point, ensuring that the switch happens at optimal moments and that data transmission continues as smoothly as possible, mitigating the impact on transmission rate.
3Object-affected harmful factors
If authentication process is strengthened, then security is improved, but transmission continuity deteriorates
Solution Approach 1:
The patent segments the authentication function across multiple access points. Instead of having a single authentication process that could block transmission, each access point has its own authentication mechanism. This allows the system to maintain security through robust authentication while preserving transmission continuity by switching between authenticated access points if one encounters authentication delays.
Data Source
AI summary
A method for transmitting data includes: transmitting data by using a first access point in response to determining that the first access point is in an on-line state; and transmitting data by using a second access point in response to determining that the first access point is in an off-line state. A maximum data transmission rate supported by the second access point is less than that supported by the first access point.
