Time-Windowed Device Provisioning for Low-Power Network Onboarding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The unpredictability of the time period required for provisioning messages in wireless communication systems leads to resource wastage and inefficiency, particularly in the onboarding process of USIM-less devices, as they need to remain in connected mode for an indefinite period, consuming network and device resources.
Innovation Solution
Implementing a time window negotiation mechanism between the device and the network entities to determine a scheduled time for receiving provisioning messages, allowing the device to transition to an inactive state outside this window, thereby optimizing resource usage and power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices remain in connected mode for provisioning, then provisioning can be completed, but network resources and device power are wasted
Solution Approach 1:
The device dynamically transitions between connected and inactive states based on the provisioning time window. During the window, the device is connected to receive provisioning messages; outside the window, it transitions to inactive state to conserve power, thus resolving the contradiction between ensuring provisioning completion and reducing power consumption
Solution Approach 2:
The system implements periodic connectivity where the device connects only during scheduled provisioning time windows and remains inactive otherwise. This periodic action ensures provisioning is completed during active windows while minimizing power consumption during inactive periods
2Reliability
If devices remain in connected mode for provisioning, then provisioning can be completed, but network resources are consumed
Solution Approach 1:
The network dynamically manages device connectivity by allowing connections only during provisioning time windows. This dynamic resource allocation ensures network resources are utilized only when necessary for provisioning, preventing resource wastage while ensuring provisioning completion
Solution Approach 2:
The network implements periodic provisioning opportunities through time windows. Devices are granted network access periodically during these windows to receive provisioning messages, optimizing network resource utilization by limiting connectivity to essential periods only
3Reliability
If devices stay connected indefinitely, then provisioning reliability is maintained, but scalability is reduced
Solution Approach 1:
The system provides periodic provisioning opportunities through time windows rather than requiring indefinite connectivity. This approach maintains provisioning reliability by ensuring devices can receive messages during their active windows while improving scalability by limiting the duration and scope of network resource commitments
Solution Approach 2:
The system changes the time parameter of connectivity from indefinite to window-based. By transforming the connectivity model from continuous to time-limited periods, the system maintains provisioning reliability through guaranteed access during windows while enhancing scalability by reducing overall network resource demands
