Linked-Device Call Transfer for Signal Interference and Lag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current technology of pairing between mobile devices and vehicles, such as BLUETOOTH pairing, experiences lag and interference due to signal degradation within vehicles, leading to connectivity issues exacerbated by urban interference and weak reception in rural areas, negatively impacting user experience.
Innovation Solution
A call transfer management service that manages calls and transfers between linked devices by determining proximity, modifying call data, and optimizing connectivity by transferring calls to devices with better signal quality, using audio quality analysis to switch connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If BLUETOOTH pairing is used between mobile devices and vehicles, then device connectivity is established, but lag and interference occur due to signal degradation within vehicles
Solution Approach 1:
The system performs preliminary actions by pre-establishing link relationships between devices before calls are needed. When devices are detected to be in proximity, the system proactively sets up call transfer routes and identifies alternative devices with better signal quality in advance, so that when a call occurs, the transition is immediate rather than experiencing lag during connection establishment.
2Reliability
If BLUETOOTH pairing is used between mobile devices and vehicles, then device connectivity is established, but interference occurs due to signal degradation and urban radio frequency interference
Solution Approach 1:
The system introduces an intermediary mechanism by implementing a call transfer management service that monitors signal quality and intermediates call routing between devices. When signal interference is detected on the primary device, the service acts as an intermediary to transfer the call to an alternative device with better signal quality, thereby eliminating the harmful effects of interference without disrupting the user's call experience.
3Reliability
If call transfer between devices is implemented, then connectivity is optimized, but system complexity increases
Solution Approach 1:
The system implements self-service by enabling devices to automatically monitor their own signal quality, identify when they are in proximity to linked devices, and autonomously participate in call transfer decisions. The call transfer management service on each device handles its own connectivity optimization without requiring complex centralized control, thereby reducing overall system complexity while maintaining reliable call connectivity.

AI summary
Concepts and technologies disclosed herein are directed to providing a call transfer management service that enables management of calls and call transfers between linked devices to provide optimal connectivity for calls. A system can receive a notification that a first device and a second device are linked devices. In response, the system can determine that the first and second devices are linked devices. While the first and second devices remain within proximity of one another and in response to determining that the devices are linked, the system can modify call data associated with outgoing calls from the second device to assign a telephone number of the first device to the outgoing calls and modify call data associated with incoming calls to the first device to reroute the incoming calls to the second device. The system can also transfer an in-progress call handled by the first device to the second device.
