Vehicle Voice Link Handover via Background Network Relay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication between vehicle occupants is disrupted when the maximum range of the mesh network is exceeded, leading to connection loss and interference, especially in open vehicles like motorcycles and quad bikes, where background noise further hampers communication.
Innovation Solution
A method that establishes a network-spanning replacement connection using a background system to manage anonymized identifiers and connection information, allowing communication units to continue voice communication despite direct connection interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a direct link is used for voice communication between communication units, then communication quality is improved, but connection reliability deteriorates when the maximum range is exceeded
Solution Approach 1:
The patent introduces a background system as an intermediary that manages anonymized identifiers and connection information. When a direct link is interrupted, the background system mediates the reconnection process by facilitating the establishment of a replacement connection between the communication units, thus maintaining reliability without requiring direct continuous contact between the units themselves.
Solution Approach 2:
The patent performs preliminary actions by pre-storing anonymized identifiers and connection information in the background system before direct links are needed. This allows the system to quickly establish replacement connections when direct links are interrupted, reducing the time and complexity of reconnection operations.
2Reliability
If anonymized identifiers are stored and managed in a background system, then connection reliability is improved during interruptions, but system complexity increases
Solution Approach 1:
The patent extracts the complexity of managing connection information and identifier assignment from the communication units themselves and places it in a separate background system. This allows the communication units to remain relatively simple while the background system handles the complex tasks of storing anonymized identifiers and facilitating reconnections.
Solution Approach 2:
The patent uses anonymized identifiers as simplified copies or representations of the actual communication unit identities. These anonymized identifiers are stored in the background system and used to establish connections without requiring the exchange or management of complex personal data or detailed unit information.
3Measurement precision
If personal data is exchanged for establishing connections, then connection accuracy is improved, but privacy protection deteriorates
Solution Approach 1:
The patent uses anonymized identifiers as simplified copies that suffice for establishing and maintaining connections. These anonymized identifiers allow the background system to accurately match and connect communication units without requiring or exchanging personal data, thus maintaining connection accuracy while protecting privacy.
Solution Approach 2:
The patent extracts only the essential information needed for connection (anonymized identifiers) from the full set of personal data that would otherwise be required. This extraction process maintains sufficient connection accuracy while removing privacy-sensitive information from the exchange between communication units.

AI summary
The invention relates to a method for continuing a voice connection established via a direct connection (10) when this direct connection (10) is interrupted between two communication units (12a, 12b) connected to a respective motor vehicle. The two communication units (12a, 12b) are each connected in the respective motor vehicle to at least one communication set (16a, 16b) assigned to a motor vehicle user, forming a local network. The voice connection between the communication sets (16a, 16b) is established across networks via the communication units (12a, 12b) using their direct connection. Thus, after the direct connection (10) is interrupted, a network-crossing replacement connection (22) is established between the two local networks via a background system (20) in order to continue the voice connection.
