Wireless Network Registration Using Altitude and Speed Thresholds
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing network registration processes in wireless devices do not effectively manage connections based on altitude and speed, leading to inefficient or undesired network usage, particularly in scenarios like airplanes or high-rise buildings, where alternative connectivity options like in-flight Wi-Fi or satellite networks may be more suitable.
Innovation Solution
Implementing sensors in wireless devices to measure altitude and speed, allowing network registration only when conditions meet predefined thresholds, ensuring optimal network selection based on altitude and speed criteria, such as being below a certain altitude and speed, or preventing registration when exceeding these thresholds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network registration is always initiated when a suitable network is available, then network connectivity is maximized, but unnecessary registration occurs in inappropriate scenarios (airplanes, high-rise buildings) leading to increased costs and resource usage
Solution Approach 1:
The patent changes the registration decision from a binary always/not-always approach to a parameter-based approach. By measuring altitude and speed parameters and comparing them against threshold values, the system dynamically adjusts registration behavior based on the current operational context, enabling registration only when both connectivity need and appropriateness criteria are met
Solution Approach 2:
The system implements feedback by continuously monitoring device state parameters (altitude and speed) and using this information to control the registration decision. The sensors provide real-time feedback about the device's operational context, which feeds back into the registration logic to determine whether registration should proceed, creating a closed-loop control system that adapts to changing conditions
2Measurement precision
If altitude and speed sensors are added to wireless devices, then network selection accuracy is improved, but device complexity increases
Solution Approach 1:
The patent leverages the universality of modern wireless devices by utilizing existing sensors (barometric pressure sensors and motion sensors) that were originally designed for other purposes (altitude measurement for weather compensation, speed for motion detection). By repurposing these existing components for network selection, the patent achieves improved measurement precision without significantly increasing device complexity
Solution Approach 2:
The system uses the device's own existing sensor capabilities to make autonomous decisions about network registration. Rather than requiring external input or complex configuration, the device self-evaluates its operational context using its built-in sensors and automatically determines whether registration is appropriate, reducing the need for additional control infrastructure

AI summary
A system of a wireless device for managing network registration procedure based on the device's altitude and speed is disclosed herein. The wireless device includes an altitude sensor to measure the device's altitude and a speed sensor to measure the device's speed of travel. The wireless device identifies, by a Public Land Mobile Network (PLMN) identifier, at least one telecommunications network available for connecting at a current location and initiates a network registration procedure with the telecommunications network when the altitude of the wireless device is less than or equal to an altitude threshold, the speed of the wireless device is less than or equal to a speed threshold, or both. When the altitude of the wireless device is greater than the altitude threshold, the speed of the wireless device is greater than the speed threshold, or both, the wireless device is prevented from initiating the network registration procedure.
