Hands-free Device Data Transfer Control During State Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques for transferring phone data from a mobile phone to a hands-free device face challenges in maintaining data consistency when the phone communication state transitions during the transfer process.
Innovation Solution
The hands-free device employs a hardware processor to establish connections using both hands-free and data transfer protocols, executing transfer control based on the type of data and the phone communication state, ensuring seamless data transfer and storage while handling state transitions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If phone data is automatically transferred from mobile phone to hands-free device using conventional techniques, then data transfer is achieved, but data consistency cannot be efficiently maintained when phone communication state transitions during transfer
Solution Approach 1:
The system dynamically adjusts the data transfer process based on real-time phone communication states. The hands-free device monitors state transitions (idle, incoming call, outgoing call, on call) and adaptively controls data transfer operations, switching between continuous transfer and suspended transfer modes to maintain data consistency while adapting to changing communication conditions
Solution Approach 2:
The system implements feedback mechanisms where the hands-free device receives notifications about phone communication state transitions and uses this information to adjust transfer control. The transfer control unit continuously monitors communication state feedback and modifies transfer operations accordingly, ensuring data consistency is maintained through responsive control based on real-time system state information
2Productivity
If data transfer protocol is established between hands-free device and mobile phone, then phone data can be transferred, but communication stability is affected when phone communication state transitions during transfer
Solution Approach 1:
The system segments the data transfer process into multiple phases based on communication states: initial connection phase, active transfer phase, and post-transition phase. Each phase has specific transfer control rules, allowing the system to optimize transfer efficiency during stable periods while ensuring communication stability during state transitions by pausing or adjusting transfer operations appropriately
Data Source
AI summary
A hands-free device is disclosed, in which a memory and a hardware processor connected to the memory are included. The hardware processor establishes a connection with a mobile phone using a hands-free communication protocol for making a hands-free call. The hardware processor establishes a connection with the mobile phone using a data transfer protocol for transferring phone data about a phone to receive the phone data transferred from the mobile phone, and stores the phone data into the memory. When a phone communication state of the mobile phone is transitioned while the phone data is being transferred, the hardware processor executes transfer control in accordance with transfer criteria, each depending on a type of the phone data being transferred and the phone communication state after the transition.
