Base Station Key-Ready Detection Before Client Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Delays in the installation of encryption keys between client computing devices and base stations in wireless networks can affect communication performance, particularly in scenarios where the base station is unable to process application data until key installation is complete, leading to dropped packets and reduced performance in time-sensitive applications.
Innovation Solution
A client computing device initiates a handshake with a base station to obtain encryption keys and transmits a test message with a distinct payload to determine when the base station has completed key installation, allowing it to resume data transmission only after confirming the base station is ready to process the data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption keys are generated and installed during roaming process, then secure communication is established, but communication performance is degraded due to installation delay
Solution Approach 1:
The patent applies preliminary action by having the client device proactively detect the base station's key installation status through test messages before actual content data transmission begins. This early detection mechanism allows the system to prepare for potential delays in advance, enabling the client to wait appropriately for key installation completion without unnecessarily delaying the communication process, thus resolving the contradiction between establishing secure communication and minimizing installation delay.
2Speed
If content data is transmitted before key installation completion, then transmission speed is improved, but data loss occurs
Solution Approach 1:
The patent implements feedback by having the client device send test messages to the base station and analyze the responses to determine key installation status. This feedback loop provides real-time information about whether the base station has completed key installation, allowing the client to make informed decisions about when to transmit content data. The feedback mechanism ensures that content data is only transmitted when the base station is ready, preventing data loss while minimizing transmission delays.
3Loss of information
If test messages are transmitted to detect key installation status, then data loss is prevented, but additional communication overhead is introduced
Solution Approach 1:
The patent applies the taking out principle by extracting the key installation status detection function into a separate, independent test message exchange that is distinct from the main content data transmission. This separation allows the status detection to be performed independently and efficiently, preventing data loss through dedicated status checking without unnecessarily complicating the main communication flow. The test messages are minimal and focused solely on status detection, reducing the overhead burden.

AI summary
A method in a computing device includes: establishing an association with a base station; initiating a handshake with the base station to obtain an encryption key; prior to transmitting content data associated with an application executing at the computing device, transmitting a test message to the base station, the test message containing a payload distinct from the content data; determining, based on a message received from the base station after transmission of the test message, whether the base station has completed installation of the encryption key; and in response to determining that the base station has completed installation of the encryption key, transmitting the content data to the base station using the encryption key.
