Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi roaming assistance methods are unreliable in adapting to dynamic movements of mobile users, leading to delays and interruptions in connectivity due to unsuitable network device recommendations and inefficient scanning processes.
Innovation Solution
A network device equipped with roaming management logic that obtains location and motion data of a wireless device to generate a sorted and prioritized list of neighboring network devices, minimizing the need for extensive scanning and ensuring seamless transitions.

Engineering Contradiction Analysis
1Reliability
If a network device recommends a neighboring network device for Wi-Fi roaming, then the wireless device can maintain connectivity, but the recommendation may be unreliable when the wireless device is moving away from the recommended network device
Solution Approach 1:
The network device proactively obtains motion data and location data of the wireless device before the device actually needs to roam. By predicting the device's movement trajectory and obtaining data in advance, the system can pre-generate a prioritized list of neighboring network devices that will be suitable for roaming, rather than reacting after the device has already moved away from the recommended network.
Solution Approach 2:
The system dynamically adjusts the roaming recommendation based on real-time motion data and location data. Instead of providing a static list of neighboring networks, the system continuously updates the prioritized list based on the device's current movement characteristics, ensuring the recommendation adapts to the device's actual trajectory and intentions.
2Measurement precision
If the network device provides detailed roaming information, then the roaming assistance becomes more accurate, but the scanning process becomes less efficient
Solution Approach 1:
The network device performs scanning and data collection in advance by obtaining motion data and location data before the actual roaming event. This preliminary action allows the system to pre-process and prioritize neighboring network information, so when roaming is needed, the system can quickly present an already-sorted list rather than performing extensive scanning at the moment of transition.
Solution Approach 2:
Instead of providing uniform detailed information about all neighboring network devices, the system selectively provides detailed information only for networks that are locally relevant based on the device's motion and location data. The prioritized list focuses scanning and data collection efforts on the most likely candidate networks, improving efficiency by avoiding unnecessary scanning of irrelevant networks.

AI summary
Devices, networks, systems, methods, and processes for providing roaming assistance to wireless devices are provided herein. To provide roaming assistance to a wireless device, a network device may establish a communication link with the wireless device. The network device may then obtain at least one of motion data or location data of the wireless device. The network device may obtain the motion data or the location data based on at least one of a set of movement characteristics of the wireless device, a set of location characteristics of the wireless device, or one or more RF parameters of the wireless device relative to at least one neighboring network device. The network device may then generate a list of one or more neighboring network devices based on the obtained motion data or the location data, and transmit the list of one or more neighboring network devices to the wireless device.
