Resetting Non-Responsive Mobile Units via Data Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Non-responsive mobile units, such as telematics units, can occupy cellular traffic channels, leading to network resource seizures and inability to resume normal voice calling operations, posing challenges for network providers to reset these devices without user intervention.
Innovation Solution
Establishing a wireless data connection with the non-responsive mobile unit over the same cellular traffic channel to transmit a reset command via a processor-executable protocol, allowing the device to reset and resume normal operations before network provider intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mobile unit occupies a cellular traffic channel in a non-responsive state, then the mobile unit continues to occupy the voice channel, but network resources are seized and normal voice calling operations cannot resume
Solution Approach 1:
The mobile unit is enabled to reset itself autonomously by executing a reset command received via data connection, without requiring network provider intervention or user action. The device self-diagnoses its non-responsive state and self-corrects by resetting its voice call stack, thereby serving itself to resolve the contradiction between maintaining channel occupation and restoring responsiveness.
Solution Approach 2:
A data connection serves as an intermediary communication path to deliver the reset command to the mobile unit. This intermediary channel allows the network to communicate with and reset the non-responsive device without requiring the voice channel to be functional, thus resolving the resource seizure issue while maintaining network control.
2Ease of operation
If network providers attempt to reset non-responsive devices, then device reset may be achieved, but user intervention is required and network resources remain occupied during the process
Solution Approach 1:
The mobile unit autonomously executes the reset operation upon receiving the command, eliminating the need for user intervention. The device self-manages the reset process including terminating the voice call stack and restoring normal operations, thereby simplifying the operation while reducing the time network resources remain occupied.
Solution Approach 2:
The reset command is transmitted proactively while the mobile unit is still in the non-responsive state but before network resources are permanently allocated or user intervention is sought. This preliminary action enables rapid reset execution, minimizing resource occupation time and simplifying the overall process.
3Productivity
If the mobile unit is reset before network provider intervention, then network resource seizures are prevented, but establishing data connection over occupied channel is required
Solution Approach 1:
The cellular traffic channel is utilized for dual purposes: maintaining voice channel occupation and establishing data connection for reset command transmission. This multi-functionality allows the same physical channel to serve both voice and data communication needs, enabling reset operations without requiring additional network resources or complex multi-channel coordination.
Solution Approach 2:
The data connection acts as an intermediary mechanism that operates parallel to the voice channel occupation. By using data bearers as a separate communication layer, the system can deliver reset commands without interfering with the voice channel state, thereby preventing resource seizures while avoiding the complexity of modifying voice channel protocols.

AI summary
A method for resetting a non-responsive mobile unit then-currently occupying a cellular traffic channel of a wireless network is disclosed herein. The method involves recognizing, at an external entity, that the mobile unit is in a non-responsive state that is occupying a voice channel of the cellular traffic channel, and establishing a wireless data connection between the mobile unit and an external entity over the cellular traffic channel. A data message is transmitted to the mobile unit from the external entity, where the data message includes at least a command to reset the mobile unit. In response to receiving the data message, the method further involves resetting the mobile unit via a protocol initiated by a processor associated with the mobile unit.
