Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual onboarding procedures are used for devices to private cellular networks, then device authentication and configuration can be controlled, but the process is time-consuming and inefficient
Solution Approach 1:
The patent implements self-service by enabling devices to automatically detect UWB base stations, request SIM configurations, and complete onboarding procedures without manual intervention. The device autonomously communicates with the SIM broker to receive and install eSIM configurations, eliminating the need for manual onboarding while maintaining security through automated authentication protocols.
Solution Approach 2:
The system performs preliminary actions by pre-configuring UWB base stations with SIM broker connections and pre-generating device identity information. When a device enters the network area, the UWB base station automatically initiates the onboarding process by detecting the device and requesting SIM configuration from the SIM broker before the device needs to connect to the private cellular network.
2Reliability
If separate devices are used for connectivity and location tracking, then functional requirements can be met, but device carrying burden increases
Solution Approach 1:
The patent applies multi-functionality by enabling a single device to perform both connectivity establishment and location tracking. The device uses its UWB capabilities to detect base stations for connectivity onboarding while simultaneously allowing the system to track the device's position. The eSIM configuration enables the device to maintain both communication and location services through a single integrated platform.
Solution Approach 2:
The system merges connectivity and location tracking functions into a unified process. The UWB base station combines device detection for connectivity purposes with location tracking in a single operation. The SIM broker integrates both functions by managing device identities for network access while maintaining position information, eliminating the need for separate dedicated devices.
3Productivity
If automated onboarding is implemented, then onboarding efficiency improves, but system complexity increases
Solution Approach 1:
The patent introduces a SIM broker as an intermediary component that simplifies the automated onboarding architecture. The SIM broker acts as a mediator between UWB base stations and devices, handling SIM configuration generation and distribution. This intermediary layer abstracts the complexity of automated authentication and configuration management, allowing base stations to simply detect devices and request configurations without implementing complex onboarding logic.

AI summary
A method of self-onboarding of a wireless device to a private cellular network includes detecting an ultra-wideband base station of an ultra-wideband network, the ultra-wideband network connected to a SIM broker, connecting the wireless device to the ultra-wideband base station in response to detecting the ultra-wideband base station, transmitting a request to connect to a private cellular network to the ultra-wideband base station, and receiving a SIM configuration generated by the SIM broker. The request to connect to the private cellular network is transmitted by the wireless device, a destination of the request is the SIM broker, and the SIM configuration is received from the ultra-wideband base station. The method further includes installing the SIM configuration to an eSIM of the wireless device and establishing a connection between the wireless device and the private cellular network using the installed eSIM configuration.
