Radio Call Re-routing for Low Smartphone Battery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current radios operating in collaborative mode do not account for low smartphone battery levels, leading to communication failures when the battery is depleted, necessitating a solution for call re-routing.
Innovation Solution
A method where the radio monitors the smartphone's battery level and, when it falls below a threshold, connects to a new talkgroup via a narrowband network, rerouting calls to ensure continuous communication without relying on the smartphone, using a newly-created talkgroup for communication through the narrowband network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the radio operates in collaborative mode using the smartphone's broadband network, then communication capability is improved, but reliability deteriorates when the smartphone battery is low
Solution Approach 1:
The system monitors the smartphone's battery level in advance and detects when it falls below a predetermined threshold. By detecting this condition early, the radio can proactively switch to narrowband network operation before the battery completely depletes, preventing communication failure and ensuring continuous reliable operation.
2Adaptability or versatility
If the radio relies on the smartphone for broadband communication, then network coverage is improved, but dependency on third-party device increases
Solution Approach 1:
The patent introduces a conditional dependency mechanism where the radio can switch between two communication pathways: using the smartphone as an intermediary for broadband access when battery levels are adequate, or directly connecting to the narrowband network when battery levels are low. This intermediary approach allows the system to maintain network coverage while reducing dependency on the smartphone under critical conditions.

AI summary
A method and apparatus for re-routing a call a when utilizing a collaborative mode of operation is provided herein. During operation, when a radio is operating in a collaborative mode, a battery level of the smart device will be monitored by the radio. If the associated smart device's battery is below a predefined threshold, the radio will be connected to a new talk-group via a standard narrowband network. As a consequence, each outgoing (or incoming) call from the radio over the new talkgroup on the narrowband network will be re-routed to the broadband network via the narrowband network (without utilizing the smart phone).
